    This is the absolute easiest way to give lysine to a cat.

    Great product. Fast shipper by Wapito11/24/2012

    Our cat would not eAt another lysis product our vet gave us but he loved this product. Not available in mAny stores so this was a great wAy to buy it

    Worth trying by Faye09/22/2013

    Bought these as Lysine was recommended for my cats sneezing, and he wont eat the lysine medicine you can put in their food. At first he wouldn't eat them but mixed them with some other treats so now he eats them fine. Seems to help the sneeze a bit, so will continue to use.

    Enisyl-F Lysine Treats for Herpes symptoms by happykitty from SF Bay Area, CA10/04/2011

    The Enisyl-F Lysine Treats are wonderful for helping relieve symptoms of feline herpes. Stops the sneezing, stuffy nose, weepy eyes. The cats love their taste and eat them up better than any other treat I've tried. Seems to be more effective than the powder sprinkled on canned food, and infinitely better than the pastes as most of the cats won't eat the pastes.

    Disappointed by gemcat from Brooklyn07/29/2012

    Manufacturer changed product - my Persian used to love these, bought them bi-monthly. Now they are smaller, lighter in color and she no longer eats them. Trying the semi-soft treats now to get her the lysine supplements she needs to combat herpes outbreaks. Very disappointed in change in product.

    I have two cats with herpes virus; one is 15. Before I found these treats, she had a URI almost daily.

    My cat thinks these are her treats, not her meds! by Kali's Mom11/15/2011

    I give our rescue cat Kali the Enisyl-F paste in her food twice a day. On top of that, I throw her the treats down the hall so she gets her excercise while she's getting her medicine. She literally stands below the container in the kitchen and begs for her Enisyl-F treats. When she is having a flare up, I give fer a few extra, along with some of the paste. We've been able to control her feline herpes very well with these products. Thank you EntirelyPets!!!

    best price by cooncatlover from Indianapolis, IN10/23/2012

    My vet put my cat on these treats for an eye issue. I could not continue to pay as much as they charged, so decided to try to buy online. The difference was way more than half of what I was paying. Everyone should buy their pet meds online! Plus, the service is great and the products are awesome too. My kitty has not had another eye infection since she has been using the Lysine treats and they help to make her immune system stronger also. HIGHLY recommend these treats!

    Excellent product and price by Kathleen from Ogden, Utah04/13/2012

    I was told by my vet that 90% of kittens are born with the herpes virus. I have a Siamese that is in the emergency every three months with upper respiratory infection. She suggested Lysine treats daily for 2-3 years and that would probably kill the virus. Angus has been taking the Lysine for almost 2 years now and has not been to the vet for any Infections for 2 years. I highly recommend this product for every animal.

    The Lady or the Tiger by MacMinch's Mom from New York01/20/2015

    My cat loves these treats but I never know which version of themselves they'll be (nor does my cat) when I open the bag. There's the moist, dark, sort of stinky nugget my cat likes best, or there's the dry hard blond scentless nugget he doesn't notice I've put in the bowl. When you open this bag of Ventoquinol you don't know what you'll get -- the lady or the tiger. Peculiarly inconsistent product.

    Cat's Vitamin Aid by Vter08/07/2013

    I've had my Siamese cat on these for several years and it seems to help. She readily gobbles them right up, one of her favorites. I have ordered them from this company always, best price anywhere!

    Best deal best loved by oldcatfanatic07/23/2012

    Enisyl-F had been recommended by vet; all 3 cats LOVED the treats. When I went to reorder they were not available and I took a subsitute - and only 2 cats would eat them plus they were stinky smelling! Happy to be back to Enisly-F and I know that all are getting the dose they need:)

    Great product by LilMan from Lorain, Ohio10/23/2012

    Decided to get this product after a lot of research on line about products that help with feline herpies. In about a week all signs and symptoms my cat had disappeared. I love this product and highly recommend it to anyone!

    Life Saver Product by Becky12/06/2011

    It appears that this product has been instrumental in keeping my FIV infected cat healthy and I believe in extending his life. The vet is amazed at his health. Apparently, it is also important to provide some soft food (canned) each day so that the Lysine can be absorbed at maximum benefit. He gets the Lysine every day as directed on the package.

    eeehhh by MarFazio from Dallas, TX10/12/2013

    My cat ate a couple then wouldn't touch them after that. I prefer the formula that comes in a pump....much easier to give to my cat.

    An essential part of our cats' diet by Jim from Tarrytown, NY09/18/2013

    Some years ago, when our previous 'generation' of cats were quite old, a friend veterinarian (feline specialist) told me that L-lysine 'worked' to inhibit and control a number of problems. She admitted that, at the time, it wasn't known exactly 'how & why' this amino acid supplement worked, only that it 'did' work. Given her reputation and knowledge of cats, I totally trusted her and began seeking out a viable way to give L-lysine to our cats. Without going into all the difficult ways, I can only relate that we were fortunate enough to try convention 'samples' of Enisyl-F before it hit most sales outlets. From that time on our cats have 6 pieces every morning and devour them like treats. The fact that Enisyl-F may minimize flare-up of herpes is a significant bonus, especially with eye-related issues. This is a fine product and an essential part of each day for our 4 year old guys since they were kittens.

    Best Product ever by Rose from Surprise, AZ12/08/2011

    My cat has feline herpes virus, He is 18years, and was getting a lot of flare-up. The Vet put him on the paste form of this product, but he did not like the taste, so I tried the Treats form and he loves it, If a flare-up begins I increase his dose to 10 per day and his flare-up eases. At his age a bad infection could kill him, but with this product, he is able to live a less stress full live.

    Cats love the taste by Cat lover from Medina, ohio02/23/2013

    My vet suggested I use this product. My cats love the taste and it seems to help.

    Enisyl-F Lysine Treats by Achoo06/17/2013

    When we brought out kitten home from the county animal service she had sneezing fits. The vet thought it could be a "kennel cough" or allergies and recommended Enisyl-F Lysine.. We have had her on this for 1 1/2 years and her sneezes have gone away. She thinks the Lysine is a treat and continues to get it daily.

    Enisyl-F Lysine Treats by paulaj05/09/2012

    I am not about ordering this product again. My veterinarian says that the Lysine treats are not the same when ordered online other than getting them from the vet. They say that the Lysine ordered on line is not the real product. I called the Company that makes the Enisyl-F Lysine treats and they agreed and said they do not support buying their product online but only through the veterinarian.?????????????????

    Saved my cat by Jo from Kansas City, MO10/31/2011

    This is a great product and helps my cat who has feline herpes. He loves the crunchy flavor and it helps strengthen his immune system to kick recurrent herpes infections!

    by from 02/02/2012

    My cat loves these and it is much easier for him than using the ointment. We really appreciate it. It also seems to do as well with his herpes as the ointment .

    Enisyl-R Lysine Treats

    by from 12/24/2012

    Freaking awesome savings!! by birlyjane from KC, MOKim


    Great find! by Robin from Wacissa, FL03/04/2014

    My cat Lily loves the taste of the Enisyl-F Lysine Treats! Easiest way to feed lysine I've ever found.

    Enisy-F Lysine Treats (6.35oz) by tross1 from South Lyon, Mi12/01/2013

    Our vet recommended this product to aid our cats immune system. We give him 4 treats 3 times a day. In order to get our cat to eat these treats we started by giving him just 2 treats at a time while holding his regular cat treat bag. After several attempts with him getting no treats for the day he now takes his Lysine eagerly (looking forward to his other anticipated treats - which of course he gets) Product is competitively priced - We save cost by purchasing the quantity that provides free shipping.

    L-Lysine Treats a Hit with Tawny by Bobby from Houston, Texas03/28/2014

    My orange and white Tabby cat Tawny was born with feline herpes virus. It causes outbreaks of nasal congestion, sneezing and occasional fluid in one eye. The L-Lysine treats are a big help in suppressing the virus. There is no permanent cure but it can be controlled and the treats are a big part of that. He loves them and eagerly eats as many as 12 in one day when symptoms flare up. I recommend the L-Lysine treats because you can easily vary the dose. If you have other cats, as I do, you can give them ordinary treats when you give your other cat the L-Lysine treats so they won't feel left out!

    by loves cats07/24/2013

    They do seem to help with my sneezing cats. Everyone looks for the "treat" when they hear the bag opening. Originally recommended by my vet.

    Seem to be OK by tcgg from nj04/23/2014

    These are accepted OK, not great, but OK. The one thing to note is that, if left out, as in if she dosn't eat them all right away, they get hard. Once hard, my cat rejects them. You have to give 6 - 12 pieces a day but they are small so that is OK.

    Best product for my cat by ridgehaus23 from Freeland,Mi11/20/2011

    My stray cat was prescribed lysine powder.The powder had to be put in wet food- I have 5 cats which made it difficult to feed just one, then I was on this website and thought I would try It. What a fabulous product! This is so easy to give and Squeeky loves it!!!

    My Cats LOVE these by Tina from Arkansas05/05/2012

    I can't keep enough of these in the house. I have 4 cats of my own and 3 foster cats. When I get these treats out they come running. It does wonders in preventing URI infections. Next time I'm ordering 4 bags!

    Finally under control by Jeannie05/29/2012

    My 1 yr old kitty was diagnosed with Feline Herpes back in Oct. Since then we've made countless expensive trips to the vet for steroid shots...all to have it come back with a vengeance. I purchased this product as a last resort and gave her the prescribed 6 treats a day. It did nothing. But then I read that some folks were giving their cats double the dose. I started giving her 12 treats a day (4 treats 3X/day.) I am happy to report that her herpes is FINALLY under control. She still has a little redness from time to time but it is manageable. Tried the other brand of Lysine treats but she turned her nose up at it. She loves these!!! Very happy with this product.

    by from 12/16/2013

    We use these for both our inside and especially our outside feral cats. We have seen the outside cats eyes brighten, skin/fur look better and they have overall been much healthier. Seems silly, but we really attribute this to the ongoing use of Lysine.

    effective help by dee from Los Angeles, CA05/18/2013

    Enisyl-F Lysine Treats have really helped my cat's feline herpes eye infection. I recommend it to anyone whose cat has this problem. My cat came from the shelter as a kitten with his eye already bad. It got terrible, and a new vet recommended this product. I am glad she did!!!

    Lysine Treats don't cut it by Fubarahh from Hackensack, NJ12/12/2011

    Our kitty, Smokey, needs to have Lysine every day for feline herpes, and we figured we'd give these treats a try. He hated them and refused to eat them! And he likes everything food related, especially human food. We couldn't get him to eat these for love or money, and eventually we threw them out. A total waste of money, sorry.

    A couple of sniffs and that was it by Croucher08/25/2011

    Each of my cats are good eaters, and one of them has never turned down a treat. She looked at me when I put this down as if to say, "You've got to be kidding." Complete waste of my money.

    Lysine helps cat with feline herpes by skidrow from Long Island NY12/16/2011

    I have been using Lysine at the recommendation of my feline optomitrist for the better part of 3 years. I give my cat 6 treats a day, usually at night. In addition I mix in the powder from 1 Llysine capsule in the canned food he shares with his brother. This has really helped to prevent him from having flare ups.

    Great product by Gerry from I live in Myrtle Beach01/01/2014

    I have been using this Lysine Product for a few years now. It helps keep my boys healthy and free of colds. It was recommended by a Vet and It works so well! I give them 6 each a day in the morning. Albert and Willie love them and can't wait till I give them their Lysine treats!

    Easiest Cat medicine - supplements to give by Sophiegirl12/21/2012

    Fabulous product. My cat has herpes simplex in the eye and the vet said to put her on Lysine. He gave me it in a gel form but the cat did not like it very well. My sister told me about these Lysine Treats and how her cat loves them. I ordered them right away and my cat begs for them. This has been a great way to get a cat to take something like a medicine/supplement. Wish all meds could be administered this way! I highly recommend this product!

    Good Choice for hard to medicate cats!! by Boo Kitty03/02/2012

    I originally bought these treats because it was sometimes difficult to give kitty the gel. She comes to the kitchen every night before bedtime to get her Lysine Treat. I highly recommend these for those difficult cats who are hard to medicate orally.

    Awesome Enisyl-F Lysine Treats by Mary04/30/2012

    My cats can not get enough of these treats. I can bribe them any time I want with the offer of Lysine treats. P. S. I bought 7 packages of them!

    My cats love them by lp from Woodland, CA10/16/2011

    This product works great for cats that won't eat the liquid form. My cats love them and eat them right up! We have 5 indoor cats and need to keep them healthy and this really works.

    Cats love them! by Hallright from Roseville, CA08/08/2014

    My cats love these treats. Unfortunately, they haven't helped my black Persian, Annie, with her runny eyes. She doesn't seem to be sneezing as much however!

    Great Immune System Booster by jfortes01/20/2013

    I have been giving this to my cats for a long time now to strengthen their immune system. I care for several cats that have a recurring virus and this keeps it from being too severe. They still get sneezy but it hasn't evolved into an upper respiratory problem. I would definitely recommend them for any animal that needs their immune system boosted. I started mine on them per my vet's recommendation and receive them every month on auto ship which is a big plus.

    A great find! by moongazer03/12/2012

    This has proven to be a great way to get my cat the required amount of Lysine she needs every day. Her outbreaks are well under control because I can get the entire dose in and not fight with the oral syringe and make her anxious!

    by kristina from Kent, OH06/26/2012

    This works really well for my two girls - I use the minimum recommended dose daily for them, but when they start to seem like they're having a reaction of some kind, possibly even allergies, I give them the maximum recommended dose and it seems to clear things right up for them! Nice way to stay out of the vets. :)

    Good product easily administered by Critterchic from VA10/29/2011

    I fostered a kitten that had the herpes virus. He spread it to my other cat. We now treat both cats with treats. Looks like catfood, just measure out the dosage. No mess no mixing no fuss. This is the second batch we ordered so far so good. Also Entirely has the quickest shipping. I ordered it on a Thursday and got it in the mail on Sat. GREAT JOB

    very happy w/purchase! by catlindacat13 from milford,ct02/07/2012

    myself and my cat trey are very happy w/ the lysine treats, trey was very sick nov/dec from a kitten we adopted infected him w/ a very bad upper respiratory infection and feline herpes. he was very sick and wouldn't eat and the vet had to insert a feeding tube it was a terrible ordeal and while he was in the hospital the dr recommended we use the lysine to boost his immune system so i picked up the pills at the vit store and was giving them crushed w/water thru his feeding tube, so after they took the tube out i would mix it w/ his food but then i looked online to see if there was any kind of treats because trey loves his treats and he loves these that i purchased, i will be ordering more since he will have to have the lysine the rest of his life. thankyou!!!!

    Enisyl-F Lysine Treats -finally, something works! by Happy Cat Mom! from Ohio05/10/2010

    Barn-E-Cat went thru a lot of medical problems; we found him when he was about a year old and starving. He lost almost all of his teeth; still had one "weeping" eye from virus. These lysine treats have done the trick!! and economically, too. I've never submitted a review before, but am happy to send this one! He gets five AM and PM mixed in with his food and loves them. (No problem eating dry cat food without teeth; glad his vet was glad about that.)

    Tom has herpes virus he was born with in his eyes and the chews really seem to help irratation and drainage problems he has. shipping and prices were fair and will buy again.

    by Toby from NJ03/11/2012

    This product was recommended by our Vet. Only one of my 3 cats will eat them!! This has nothng to do with the product but with my finicky kitties. I even tried crushing them and putting in their food. I stand firm on the product and would definitely recommend. However, a smaller trial package is suggested to see how one's cat will take to them. Thanks!

    by from 11/10/2011

    I adopted several kittens over the last few years from a cat shelter and some of them have Kitty Herpes, which causes respiratory illnesses and watery eyes and stopped up noses, etc. Lysine was recommended to me by the vet. to help with these ailments. I appreciate being able to buy these products from your store at a bit of a discount compared to the vet's prices. This helps me with my budget!

    Great for Allergies! by Laurie07/31/2014

    My vet recommended this product because all of the sudden my cat's one eye was tearing up all the time and oozing plus she would get a droopy eyelid. I gave her the recommended double dose the first couple of days then backed down to the daily dose and her symptoms cleared up within two days. There are times when I forget to give her the treats (because I have another cat that has stomach issues and cannot have the treats and she knows when they are out) so within a day or two you can start to see the symptoms return. Once I start giving her the treats again it completely goes away. I would highly recommend this product for allergy issues.

    Herpes by Grace01/20/2013

    Good for Herpes control in cat's eye. Also good tasting. She loves it.

    My cats love them by Sandra11/17/2011

    I was afraid that my picky cat, the one who really needs the lysine, wouldn't eat them. But she loves them! Way cheaper here than from the vet.

    Healthy Cat for Half the Price by Emily Sweetpea's Mom from Burrton, Kansas10/25/2011

    Our cat, Emily Sweetpea, has a chronic sinus infection and we have learned to help her fight it with these Enisyl-F Lysine Treats. We were so thrilled to find them at EntirelyPets because we could get TWO pouches for only $4.00 more than we usually pay for ONE at our Vet's! THANK YOU ENTIRELYPETS!!!

    Poor Condition by Rusty Junior08/21/2012

    This is a wonderful product which my cat likes as long as it is fresh. I ordered a package. It was open to the air and had drawn moisture. The problem was that there was a hole punched into the top of the pouch probably to hang it on a display hook. The seal of the pouch closes to the Lysine had opened and the display hole had allowed air and moisture to enter. The top edge seal was still sealed but that did not prevent the air hole from allowing moisture and air into the Lysine. I returned the pouch immediately to you. I have had no response at all from your company.

    I have been using Enisyl-F Lysine for years. I have always purchased from a Vet-supply source. Your price is much lower and free shipping is a definite plus. I am more than satisfied.

    Not recommended by CMMartin from WA State01/31/2012

    I've tried this for my four cats, and none of them will do more than sniff at them and turn away. The size of the treats is too large, and even when I broke them into smaller bits, they had no interest whatsoever. Very disappointing!

    Enisyl-F Lysine Treats by Joan02/07/2012

    I have used this product for about 2 years for my cat who was infected with the herpes virus in her eyes as a kitten. L-lysine is known to help with the immune system, especially working on eye issues. She loves these treats and they keep her eyes clear and prevents irritation. I also feed a dry food with l-lysine as one of the ingredients.

    Enisyl-F Lysine Treats by Snaplilly02/22/2014

    Our two cats love them. They wait every morning for the treats. I give them six and if they start sneezing I give them more in the evening and it really helps them get over the sickness quickly. Sometimes they actually stop sneezing within a day or so. I will never be without them and they are a little cheaper getting them from Entirely pets than at the vet.

    great buy by kim10/28/2013

    I was so glad I purchased these Lysine treats from EntirelyPets, I save $10 on each pack. They are the exact product I got from my vet

    Best treat ever by peanut from Cape Coral, FL06/12/2013

    I ordered Enisyl-F Lysine Treats together with the L-Lysine powder. When I shake the bag, everybody comes running, sitting patiently in a half circle awaiting their part. They like the smell and the soft chew.

    Chief likes this brand the best by Chris12/25/2012

    Of the three lysine cat treats on the market, our herpes-afflicted cat Chief likes these the best.

    Great Product by Paula from Birmingham, AL07/23/2012

    My cat, Leah, has recurrent herpes eye infection. Enisyl-F Lysine powder sprinkled on her food was recommended by a veterinary eye specialist years ago. Leah rarely consumed all of the food. That jar of powder outlasted the expiration date. A year or two ago my vet suggested using the Lysine paste squirted into the cat's mouth daily. I didn't want to fight with my cat every day. Finally a neighbor introduced Enisyl-F Lysine treats to me. I found them on-line and purchased them through Entirely Pets.com. The product is great! The cat eats 6 treats every AM prior to her breakfast. She thoroughly enjoys the treats and gets her medicine at the same time. I informed my vet about the product and she passed the info on to another client who is also pleased with the ease of administration of the treats. I highly recommend this product for cats with recurrent herpes eye infection.

    Effective aid for feline herpes by tvcatrescue from Long Island, NY08/14/2014

    One of our three cats has herpes. This supplement is easy to administer: once a day I add 6 little pieces to her dry food OR to the top of wet food. I feed the cat from a separate bowl, so that I can see that she has eaten it. This has kept her herpes under control for several years now - there have been no flare ups, only a bit of tearing from one eye.

    Cats love them! by Jen02/27/2014

    Lysine is important for cats with upper respiratory illnesses or feline AIDs, or any virus. This is the treat my cats love the most!

    good purchase and better priced than at Vets by kz from Atlanta, Ga03/11/2014

    Really has helped my cat go for longer periods before having to give her antibiotics. An excellent suppliment to help with her cronic upper respitory problem.

    Great supplement for my 2 cats by Heather11/13/2012

    Wish the size of each treat was more consistent. Some bags have large ones and other bags have very small ones. But my cats eat the up regardless! Haven't had any health problems since we started using these a couple of years ago.

    Very helpful for chronic eye problems by doggymom from Dearborn, Mi.10/19/2011

    Last winter I adopted two beautiful kittens who were born outside and needed a home. Unfortunately, they both had running eyes from most likely herpes infections, according to my vet. They were given antibiotics, but the running tears continued, so I tried the Enisyl -F treats every morning with their breakfast. The results have been very good, both of them have much clearer and drier eyes. They love the treats and insist on them every day!

    My big boy has a terrible time with herpes during the spring and summer months. I feed him 5 treats a day and he hasn't had a flare-up since I started giving them to him. Excellent product but hard to find.

    I bought a bag each of 3 kinds of lysine treats, hoping that my sickly cat would willing eat one of them, and this is the one that he liked.

    my cats loves these! by chrisc from massachusetts01/12/2012

    recommended by my vet to keep my cat's runny eye issues away- my cat loves them and eats the recommended amount daily.

    Helps to Keep Herpes under control by catlover from California12/01/2012

    My cat went through months with an eye herpes eye infection. Once the right medications were found, with the help of Lysine treats it was under control. He hasn't had any further problems, as I keep him on Lysine Treats everyday.

    Help at Last! by RB from North Carolina10/29/2011

    Feline herpes is very common among cats and two of mine have really bad flares from time to time. The vets have prescribed corticosteroids for long periods of time - not always a good idea. I recommended l-lysine to friends suffering from cold sores (herpes simplex) and the lights went on when I found Enisyl-F. These "treats" are very well tolerated and have moderated herpes outbreaks to the point that I have discontinued using steroids. My vets concur that L-Lysine is a great way to deal with feline herpes. Thank you!!! My cats LOVE them!

    Different from before by Deb12/01/2014

    I have been giving my cat these for years now. However when I opened the ones that I recently purchased, they were different in color and shape. When I contacted Entirely Pets, a nice young man named Michael checked with his Product Director; Nino and they assured me that the manufacturer had changed them and that they were good to use.

    Happy kitties by Moo03/11/2013

    After several years of not knowing what was causing our cats to sneeze so much and so gross (including visits to two different vets) these Lysine treats have helped tremendously. Both cats like them and we have already seen a marked difference in their well being. Well worth the price.

    by tom from tucson,az05/15/2013

    A speedy delivery after placing order and a great price.

    Great Product Great Company by Lisa from Minnesota01/16/2012

    My cat Wolf loves these treats. He has no idea they are good for him. His herpes has been under control since he started this product. As of today, the website says to give 5 tablets a day which provides 250 mg. The package says to give 6 for the 250 mg. Wolf gets 6 a day. Another great thing about ordering from Entirely Pets is that they contribute a percentage of my purchase to my favorite animal charity as long as I log into Entirely Pets through the charity's site. This way my cat Wolf gets his "treats" and other pets are being helped same time. It's a Win - Win! Thank you Entirely Pets!

    Great lysine treat by lauracaron from Chicago, IL06/06/2013

    My vet recommended this treat and I had to buy it from the vet at the time at a higher price and whenever they stocked it. Entirely Pets has it at a good price and at any time and they ship so fast. Great company to buy from.

    same good treats by cat house04/13/2013

    This is probably the sixth bag we've used with the first being from the vet which was more expensive. None of our cats have turned up their noses at the treats and they always disappear even with our toothless cat.

    Great supplement by Dudley's servant from Myrtle Beach SC10/17/2013

    Cat likes this product better than another brand which is hard to chew and has difficulty swallowing. This brand is soft and is very like other cat treats and don't have to force cat to take.

    Service is Awesome! by catlover06/23/2012

    My vet put my Maine Coon cat on these treats when she got herpes conjunctivitis. A pack of these at their office cost $40.00. The service was absolutely excellent from your company, the product very reasonably priced, shipping was very fast, and my cat fights me to give her these; she loves them! I will definitely continue to use your services in the future. Oh, and they work well too!

    easy to use product by nfg12/12/2011

    I've been using this product for my cat with feline herpes. They are easy to get her to take and I have been successful keeping her out breaks to a minimum.

    different by jw09/10/2014

    The lysine treats were different from the ones I received from my vet, despite being the exact same brand. They were much lighter in color, less moist, and looked "old"; surprising and somewhat disappointing. Cat still eats them, nonetheless.

    Good treats by Delref307/26/2012

    Use to buy at our Vets for $21 a bag. They are good for our cats health and they eat them up. These only cost around @13 a bag so we save $7 a bag so we stock up on 3 or more per order. Glad I found Entirely Pets!

    Great Product! by Barb10/31/2012

    Was cat sitting for my daughter while she was on vacation. She was low on the Lysine treats and suggested that I order Enisyl-F-Lysine Treats.. Her cat has had a Herpes virus in her eyes and has been eating the Lysine treats on a regular basis to help keep the virus infection from coming back. It has worked great.

    Worthy purchase, but I hoped for better. by JP from Vernon, NJ03/15/2012

    Since I've started feeding these treats to my cat, I've definitely seen improvement. She used to have a constant sinus infection due to feline herpes, and we've seen definite improvement on that front...but we're talking degrees. The nasal discharge is still there on a near-constant basis though the content and consistency of the fluid has improved greatly, and her cough is much less frequent. Her sneezing (multiple times every day) is just as frequent as ever. Regardless, I'd still recommend this product since there has been visible improvement in her condition. It's just not quite as effective as I'd hoped. It's looking like we're headed for a 3rd antibiotic injection within the last few months.

    Ensisyl-F Lysine Treats by Star's Daddy from Kingsville, Texas04/07/2014

    My cat, Star has feline herpes and at her current age (13yrs) she has flare ups that cause sneezing and coughing. My local vet recommended this supplement and I started about five months ago. It works. Her health has improved ( no more sneezing and coughing) and she's gained weight and strength.

    Lysine by Cindy from South Carolina11/06/2012

    These lysine chews made it very easy to keep my 3 cats free from symptoms of a feline herpes virus they picked up.from another cat.

    by from 02/16/2012

    My beloved vet recommended this product for my little BearBear. He loves the 'treats' & they are very good for him. So, it is definitely a win win!

    L-Lysine Treats by TN from Baltimore, MD01/23/2013

    My cat LOVES these treats and I'm so thankful, because he needs lysine to control his chronic herpes condition in his ears, nose, eyes and throat.

    speedy delivery by CKK from rural north California03/05/2013

    I'm still trying to figure out how I get what I order on line the following day! My vet recommended Enisyl-F Lysine for my cats as they all have Herpes. Unfortnuately for some time either one or another were sneezing, conjested and miserable. My vet said they all had chronic upper respitory illness (herpes). Lysine is magic. Their bouts are less often and much less severe than they used to be. Ordering through entirelypets.com is less expensive and FAST. It almost would take me longer to go to the vet to get them!

    Enisyl-F Lysine for Feline Ocular Herpes by Katsarah from Barberton, OH02/25/2012

    My cats loved the treats. We haven't seen any improvement in the cat's eye infection yet, but I understand that it can take some time, so we are still trying to see if it will help.

    A very good product by Lisa from Iowa City, IA09/15/2014

    Our vet recommended this product to control symptoms of feline herpes in a young kitten. It works very well, and I'd recommend it wholeheartedly.

    Helps with herpes by Big Rube from Gaithersburg, MD01/27/2015

    Our cat Domingo has herpes in his eyes, causing excessive tearing. Our vet recommended these Lysine treats, which he loves. I only wish our other cat would also eat them. Bottom line, the herpes hasn't gone away, but it's much better.

    by from 07/27/2012

    Cats used to fight over these treats. Now most of them will not eat them unless you mix them with wet food and you can use the powder for that at a lower cost.

    helps with viral cat diseases by DJ from Downers Grove03/18/2014

    my vet recommended lysine for Ringo. he doesn't like crush pills but loves the treats. he had a herpes condition from the shelter he was in. he hasn't had an outbreak in 5 years!

    enisyl-f lysine treats by lexy02/13/2013

    The "treats" were fine--my cats love taking their medicine in this form but, the packaging on this batch could really be improved. The resealing closure was positioned above the place where the bag opened, forcing me to cut off the resealing feature in order to open the bag--weird but true. Just means using a clothespin to keep the bag closed. It is nice to use the reseal feature, when it works.

    by from 10/27/2011

    I have a sick little cat who has been on this product for two years. It has helped to keep him as healthy as possible. The best part is that by ordering it here it is costing me less than half of what the vet had been charging!

    Disappointed in new shape & texture by Trose from Arkansas06/27/2012

    My cats used to love this product but the company recently changed the shape & texture of the product. It's too small now to be called treat size. They are shaped like little pellets of food and I see my cats spitting them out as they try to eat them. I switched brands and recently purchased Vetri-lysine plus. These are treat size and I only have to give them 2. They love them and have no issues chewing them! Plus the bag should last longer!

    A great way to administer Lysine! by Izzy's Mom from Maryland06/25/2011

    We have tried all sorts of ways to give our cat, Izzy, Lysine but I could never get enough into him to make a difference. I found that although Izzy won't won't eat these treats outright, I can, however, crush them up and mix them into his wet food. Doing this everyday has definitely helped with the feline herpes symptoms - especially with the chronic eye infections. I have to mention that my other cat will gobble these treats up right away without any crushing and mixing, but in general he's not as picky as Izzy.

    A little clumped this time by Cathy from Baltimore01/25/2015

    I really like this treat. It helps my kitties who have Herpes Virus suppress the virus and control their symptoms. This particular bag was very clumped together and abnormal looking, but they usually are very good.

    Great product by Sunkis07/14/2012

    Perfect remedy for cats with sneezing issues that are contagious to other cats. My cats eagerly ate the treats and in a matter of days the sneezing had stopped.

    Cat loves them by MAC from Verona, NJ01/11/2013

    My cat loves these treats making it so easy for me to help boost his immune system.

    Tasty treats by Michelle from La Quinta, CA04/23/2012

    You know how finicky cats can be! Our little girl LOVES these treats and we are using them as an enhancement to the Lysine that we are adding to her food. Thank you!

    Yummy! by pet lover from eastern, WI11/13/2013

    Lucy and Milo love these treats. They were a very good deal online so I bought 2 bags. This helps them from sneezing so much and was recommended by our vet. All good!

    Healthy cat by Dick from Depew, NY01/01/2013

    The treats have kept our cat healthy this year. Last year he had sneezing problems which required a human Rx to remedy. This year, no problems even though the vet. said the problems would reoccur.

    Great product - vet prescribed by lilmcmac from orlando04/04/2013

    I like this product, what it does and how well it works. But my fussy little persian gets tired of it and they are a bit hard for her to chew. So I switch to Optixcare L-Lysine for Cats, when she gets tired of it. Or try the paste as another way.

    My cats love them by kitkatfan07/23/2013

    I use this product, because my calico contracted feline herpes as a kitten. This product not only helps boost her immune system effectively, I also don't have to "force" her to eat it. She loves the taste. It has a pungent tuna smell, that appeals to cats.

    good product by catchaos03/14/2013

    Most of my cats liked the treats and it seems to be helping with runny eye issues we were having. The cat that didn't like them doesn't have any eye problems and has a real "mouth-feel" issue with all food and treats.

    Enisyl-F Lysine Treats by Rayford from Jacksonville, NC03/04/2012

    I took my cat to the vet. because he was sneezing. The vet. gave my cat a shot and avised me to give him Lysine Treats. I ordered the treats, and in the mean time my other cat started sneezing. After four days the Lysine Treats arrived. I gave the treats to both cats per directions on package. Both cats stopped sneezing after three to four days. I notice that both cats were sneezing less after the first day of taking the Enisyl-F Lysine Treats.

    Enisyl-F Lysine Treats by John01/18/2012

    Enisyl-F Lysine Treats were recommended to us by a friend as a way to help our Maine Coon combat a sinus infection. While it wasn't the cure we had hoped for it appears to have helped and the cat loves the treats.

    Treats that really treat! by SouthPhillyin AZ from Phoenix, AZ10/27/2011

    These really help Jake with his allergies.

    Tasty Treats by thompsonmd76 from Ventura, CA01/08/2013

    Our kitties love these things and come running when they hear the bag open. Easy way to ensure they get their full daily dose of Viralys. The Viralys powder is useful, but more difficult to ensure a full dose if your cats don't eat their entire meal. Our cats like to share their food (some more than others), so certain cats may get less than a full dose and some more by using the Viralys powder. The treats are easier to keep track of, albeit pricier than the powder. Definitely recommended spending the extra money if you have finicky eaters or multiple household cats.

    My 3 cats love these treats. by shopperkitten from Destrehan, LA05/02/2014

    My vet recommended these treats for one of my cats as she had ragged breathing. They cleared her right up. And she said all of my cats could eat them if they liked. I give them to all 3 from time to time. I think they keep them healthier.

    Great price and prompt delivery by jan09/07/2013

    The treats were more affordable than my vet's fee and my cat appreciates them

    easiest way to give medication by flasunshine from Seminole, Fla.09/12/2014

    Sometimes the gel form could be difficulty to give as well as quite sticky when it got on my cats fur, this is so easy and he LOOKS FORWARD TO 'TREAT' TIME!

    Its Not The Same by Jose10/23/2012

    I've been using these treats for over a year and the cat has been eating them up. Then ... same packaging ... but the treats had a different shape, lighter color, and obviously a different taste. The cat really isn't interested anymore. Sometimes, with persistence, I can force one down. Most times, no. The product only works if the cat eats them, and that's not happening much anymore.

    Two out of three is not bad! by Chrys02/07/2012

    Two of my 3 cats love these treats. Only one of them won't touch 'em. That's not too bad-the 2 that like them even prefer them over the Greenies, and they like those too.

    Great product by Ken from St. Augustine, FL12/08/2011

    Several of our cats here have regular upper respiratory infections due to a herpes virus. We give lysine treats to minimize the symptoms and it works well. The Enisyl-F treats we ordered were shipped in one day and arrived in perfect condition. Couldn't ask for more than that!

    Great Product by Jenny from Indiana11/03/2013

    Has done a good job keeping Buddy's eye discharge in control. However, do not buy to much at a time as the product does seem to get hard and lose it's smell . We store it in a plastic jar with screw -on lid, after we open the original bag. After it begins to dry out Buddy will not eat it.

    Helpful therapy for chronic Herpes eye infection by Mike from Eastchester, NY10/25/2011

    Treats that are good for health by wige03/18/2012

    Enisyl-F Lysine treats were recommended by my vet for one of my cats who is a carrier of the herpes rhino virus. I shouldn't have worried they might not eat them - all three INHALE the treats. Your site had the best price, including shipping/handling. Am very pleased And my cats are too

    Stale Treats by Annie C. from North Carolina10/23/2012

    I previously purchased this item through the local vet. The treats were fresh. When I got these Enisyl-F Lysine treats from Entirely Pets, the treats were stale. My cat doesn't eat them enthusiastically like he did before. I won't be ordering from Entirely Pets again.

    Super Product...Great Price! by Chris from Jackson, MI08/01/2014

    I've purchased these treats from entirelypets.com a few times and my cat loves them. They are a great supplement for his ocular herpes that came about after his surgery. I plan on buying more for sure.

    Great Purchase by Beaniesmom from Chicago, IL01/26/2012

    My cat Frank is on Viralys Oral Gel twice a day. I was looking for a way to get him a more regulated dose to control his symptoms since I don't measure out the gel. He LOVES these treats. I give him 6 each night instead of the gel. No matter where he is in the house he comes running when I open the bag.

    Easiest way to give Lysine by Ghost's Meemaw11/07/2011

    The only feline lysine supplement worth buying by Big Wheel from Columbus, OH02/06/2013

    When my cats contracted the their upper respiratory infection, I tried a lot of lysine supplements. I tried several treats, powders, pastes, and liquids. This is the only one that works for them. My cats readily eat these as treats, so getting them to take them is not a chore. They are the only lysine supplement that actually helps control my cats condition with no flare-ups, as long as they take five tiny treats daily. They Work!

    by Judy from California09/24/2013

    My girls love it. I orginaly got it from my Vet for one of my kitties eyes. Now both come running when I say Treats! I have recommended this to my Groomer as well.

    Great for Feline Herpes by Kathy09/25/2013

    I have two cats, male and female. The female likes these treats more than any of the other products for Feline Herpes.

    cats thinks treats are great by chris moose01/29/2013

    our owned and feral cats that we feed eat these treats before they eat the wet food that we place the treats on. Less expensive that thru the vet.

    Enisyl-F Lysine Treats - Excellent Product by Bear Bear's Mom12/06/2012

    Recommended by my kids' vet for my Bear Bear that has MRSA. He gets at least 6 of these 'treats' everyday & really likes them.

    by meomagi02/20/2013

    When my little DSH grey/white tabby wants a treat, she receives the daily recommended dosage of this treat. Sometimes she receives the recommended dosage of the Lysine paste, sometimes the "treats" as she likes to have her "treats". IF a person has difficulty giving their pet the paste formula, these treats are a great way to ensure your pet is receiving the much needed nutrient.

    Works great! by Jen from Wellsville, Ohio01/04/2012

    BEST PURCHASE EVER by jane10/26/2011


    best purchase by georgia peach from Monroe, MI06/24/2012

    I had tried various treats for my 8 year old cat, but he did not like any of them. He waits each night for the clock to strike nine, then comes and sits right in front, staring at me until I give him his 6 treats. Also, it has helped him with the sneezing he has had since he was a kitten. Recommended by his vet.

    I didn't know it was good for me! by Sinbad from Sunny California12/31/2011

    I am a 7 year old Abby who was recently adopted by a very loving home. My new vet said I had a herpes eye infection which we now have under control. She sold my mom these wonderful treats and said since I would be on these long term (I hope forever!) she should look on-line for a cheaper price - and wow I can get 3 bags from EntirelyPets for the cost of 1 bag at the doctors! Thanks for the tip Dr. Ann! Any way these are the best tasting treats I have ever tasted. The smell is delightful and the flavor is to die for. I get two bags mailed to me every two months (automatically) so I never run out. And I have not had a flare up in my eyes since! When compared to other lysine treats which only let you have 2 treats, Enisyl lets me have from 6 to 12 treats - I never feel limited or denied. Some people don't like the fact not all the treats are "purrfectly" shaped, but to us cats it all taste GOOD. So to all my fellow cats - if you need to take lysine, Enisyl -F lysine is the "cats meow" and EntirelyPets treats you like the King of the Wild that we are.

    Really helps with my cat's respiratory problems by Lynn11/17/2011

    I researched this product before I purchased it. I read many veterinarian site reviews. My cat had been sneezing and coughing. As soon as I gave this to her, she improved. Now I give it to her every day and also to my other cat as a preventative.

    Cleared sneezing, gentle on stomach by Tess02/15/2012

    When multiple rounds of veterinary prescribed antibiotics did nothing for my cat's chronic sneezing, I did some research and found out about Lysine for feline herpes. After running it past my vet, I tried these, and they have really made a difference. Our cat sneezes a lot less than he used to. He also loves the taste of these treats, and they are gentle on his sensitive stomach.

    Really great by healthful from Durango, CO07/30/2014

    My cat has a thyroid problem and is on medication twice daily. This has affected her immune system, and the vet recommended the lysine treats. I give her four each morning, which she likes, and it seems to stabilize and help her immune system.

    Lives up to its claims!! by Lil Man05/30/2012

    My adopted cat came with feline herpes but we fell in love with him the minute we saw him. Researched the helpful things for feline herpes and found these Lysine treats very much recommended! Began giving them to my cat and he has ALL his symptoms under control! No bare skin patches and his cloudy eye has cleared up also! Thank you for a wonderful product! Will continue to buy them no wondering needed!!

    Easy to administer by DC10/23/2012

    Although my cat will willingly take the gel, these "treats" make it easier to make sure she gets the right dose (just in case she's being finicky that day about the food mixed with the gel).

    Wonderful product! by feline03/23/2013

    Whatever is used to make these therapeutic treats enticing to cats really works! My cat loves the taste of the treats and the l lysine is so effective in keeping the herpes virus from cropping up in stressful situations. Great product.

    My cats love them by Wyeast from Portland, OR03/05/2014

    Both of my cats used to have herpes breakouts occasionally. I originally used the powder version of Enisyl mixed in with wet food, but they didn't always eat it all. They both went crazy for these treats when I tried them and they don't have kitty colds or conjunctivitis any more.

    by Rusty Junior from Rowlett, TX11/19/2011

    Great product with a great price!!! I definitly recomment it and Entirely Pets!!!

    Good value, about 250pcs. in bag. by craigs folly from souuthwest Ohio03/28/2014

    Both of our cats had this product suggested to us by our Vet. The Vet charges about 30% more for the identical package. I try to feed one to each cat about six times daily.Usually the cats just smell the little ball of product and down them without any problem. It seems like lately the cats will walk away from the product and I have to force feed. They don't seem to mind the forced feeding, but then cats are at best . . . strange. I do not have to use much effort when forced feeding. I would never do anyt6hing to harm my cats.

    kitty approved! by Sloane10/26/2013

    This is a great way to give your cat L-ysine if you have to give this daily.My 6 month old kitten loves them and they're easy to give as a treat. It saves me from having to crush Lysine to put in his food all the time!

    Cats Love It by Deb G from Utah04/24/2014

    My cats thinks this is the best treat ever!! And it's good for their immune system.

    Enisyl for Cats by Sebastian's Mom from Armonk, NY02/12/2012

    My adopted kitty has herpes in his eyes and gets flare ups now and then if I don't use enisyl. However, he refuses the gel form. Luckily enisyl comes in treat form. Sebbie loves his "cookies" and gets his med consistently every day. I showed these to my vet who now orders them for his practice. Great product. I even give it to my elderly kitty as a supplement for her failing eyes (vet approved!). Entirely Pets has great prices and is very responsive and reliable.

    Prescribed by Rosie from Walpole, MA01/16/2015

    This product was prescibed by my vet for my cats facial herpe. While she loves the products and eats them as if a treat, I have seen no improvment in her conditions whatsoever. I am now merely just ordering for her pleasure.

    Not the best L-Lysine treats by KImber07/06/2011

    These treats are hard, misshapen and often broken, therefore hard to give in correct dosage.

    Great product! by got3cats from Virginia12/02/2011

    I have two cats that need this supplement. One loves these treats and the other loves the paste. Great to have the choice! Price here is cheaper than what I paid at the vets - I'll be buying from this site from now on. Super fast delivery on the paste product I bought.

    My cat has seasonal allergies. Enysyl-F Lysine Treats help to calm his allergies. He really likes the taste of the treats and they save me a trip to the vet a couple of times a year. I 'll continue buying this product and I highly recommend it to my friends and other cat owners as well.

    My cats love it! The older female who won't accept Lysine paste or other options eats it up willingly and looks for more.

    Keeping feline herpes in check by Mike from Westchester, NY04/18/2013

    We've been using this product since we adopted our cat as a young kitten. We adopted the kitten from a veterinarian friend who told us of the chronic herpes eye infection the kitten was born with; he recommended this type of product. Although the condition is incurable, the addition of these treats to "Bella's" daily diet seems to keep the condition in check and the cat loves them.

    by from 06/18/2012

    This product is given by many veterenarians for a particular health problem in cats (herpetic eye condition) but I would certainly recommend it to a friend whose cat had the same problem. I got it from the vet first and the price was about 3 times more than you charged. Service was easy and delivery was prompt. I will certainly use you again.

    Thank Goodness my two little ones love these, as they really help with their calicci virus! Actually look forward to getting their "treats" daily!

    Fantastic product! by Lil Man from Ohio11/02/2011

    My cat LOVES these treats and they work amazing! With his feline herpes he will always have the symptoms but with the Lysine treats the symptoms are under control! Will ALWAYS have these for him!

    Loved by cats but expensive by Purrfect from MI11/06/2012

    Our cats love these but it is much less expensive to use the Felisyl powder to give them the dose of L-Lysine HCL they need.

    Worked Great by normah from Ontario. Canada07/31/2012

    My cat stopped sneezing within days and both my cats like the taste of the treats. I will continue to give them the treats to prevent future virus'. Only downfall is the shipping costs to Canada, It is about the same price as the product.

    My cat loves these! by lillydblue01/23/2012

    My vet advised me to start giving my cat 250 mg of lysine twice a day. Well, he wouldn't eat the pill in a 'pill pocket' and he wouldn't eat any moist food that had the grounded pill in it, so I decided to try these. He loves them! Any time he hears the bag move, he comes running. No more trying to force a pill down his throat. I love the ease in giving my cat medicine!

    Enisyl-F Treats by Joe from Missouri02/07/2013

    My cat will not eat these even when mixed in with some canned food. Stick to the paste using a syringe.

    Great Product by uukristina from Kent, OH06/28/2013

    These are really good. My one cat has a little trouble getting them in well all the time, but these help them a lot when they start to get sneezy or seem like they might be getting a cold or something. The size of the treats vary sometimes - it hasn't been a problem but in case anyone else wonders if that's normal! :)

    Great treats by Kking03/13/2013

    These treats are great! Both my cats have feline herpes and get squinty in their eyes often. As soon as I give them these treats their eyes are better! They like the taste of the treats too which is a huge plus:)

    Really helps! by sara1133 from Payson, Utah08/23/2014

    My vet recommended this for a feral kitten I adopted when'd the antibiotics did not clear up his eye infection completely -- said it is a common herpes virus that may never clear up completely. These treats have cleared his eyes to the degree that there is only a very tiny bit of issue every 2-3 days that is really no problem at all. He absolutely loves them and comes running when he hears me shake them in the package. I give the recommended 6 per day -- 3 in the morning and 3 in the late afternoon. An added bonus is that his coat has gotten incredibly soft. They have been a great investment for me and I will continue to give them to him the rest of his life.

    Formula Change? by Sebbie's Mom from Armonk, NY12/20/2012

    My kitties usually crave the Enisyl so I serve them as treats. However, once the packet was opened the kibble seemed to dry out and lose its semi-soft consistency. Now the cats won't eat them. Not sure if they changed the formula or if the product is stale.

    My cat's chase and kill "treat" by Kali's Mom from Utah04/10/2013

    I use these treats for upping the coverage of lysine for my cat Kali. I throw them one by one down the hall for her to chase and devour. She loves them, and it's an easy way for me to get extra lysine into her when her herpes is flairing up too much. I'm thankful that there are easy ways for me to get medicine into my cat rather than holding her down and forcing something down her throat every day!

    by linda from milford,ct04/02/2013

    my cat Trey looks forward to getting his lysine treats every morning!

    My cats love this. by Bubba from Canyon Country,Ca05/24/2011

    My cats love this product. You guys cost less than the stores. My cats look forward on getting their treats. It also helps them getting sick. You guys are great. Thank's for helping my cats and your prices.

    Both my cats like the taste and prefer treats over the paste.
