Vetri-Science® Laboratories’ Vetri-Lysine Plus is recommended to support immune system function, collagen formation, tissue repair, antioxidant activity and antibody and lymphocyte production. The amino acid L-lysine supports hormone, antibody and enzyme production, as well as collagen formation and tissue repair. The inclusion of DMG supports methylation, providing useful methyl groups to support the production of hormones, neurotransmitters, antibodies, nucleic acids, and other metabolically active molecules. Research indicates that supplementing with DMG enhances oxygen utilization at the cellular level and supports the immune response.

For use in cats and kittens only.

    Tasty and Healthy treat! by Molly's Mom from Wellesley Ma11/13/2011

    My cat was suffering from drippy eyes, not sure if it was allergy or immune deficiency. Since using these soft chews, my cat has been perfect. She begs for them every day! They were less expensive from Entirely Pets than the vets or anywhere else.

    Found it! by Woodson's maid from Colorado11/08/2012

    The vet recommended lysine supplements as an immune booster to fight a latent herpes infection (eye goobers) that my cat Woodson got when he lived with a hoarder. Most sources/forms of lysine I have found were a powder or oil that you put on the food, but since I have a automatic (think gum ball dispenser) feeder for everyday, this was just not practical. I looked high and low for a chewable treat containing lysine, and I finally found it, and at a great price. Bonus: Woodson loves getting his special "treat" every day and he has not had an eye infection since. Just look at those baby-blues!

    Didn't work for my cat by mastercat from Encinitas, CA03/15/2012

    My cat is infected with the herpes virus, so I give her Enisyl-F paste twice/day. I tried these soft treats to make it easier and more pleasant to take, since she will be on L-Lysine for a long time. She liked these treats, but the symptoms returned to her eyes immediately (inflamed and tearing eyes). When I went back to the paste, it cleared up the same day. So these treats didn't seem to work for my cat.

    vetri-lysine really helps! by JT from Hemet, CA06/12/2013

    My cat Joey was born with a defect in his nasal cavity that makes it more difficult to breath and he also has a tendency to get stuffed up and sneeze a lot. Giving him vetri-lysine plus "treats" every morning and evening has been like a miracle to keep his breathing less labored and keep his small nasal passage open. And he LOVES getting his treats!

    Gizmo The Cat could not live without these. by cey from Maine10/28/2011

    Cuts back on sneezing, scratching, and helps her from contracting urinary tract infections. Consider purchasing them for any older cat. Gizmo is 13.

    Works When nothing Else Did by Me71901/26/2012

    I took my cat to the vet for a eye nfection. I was told there was nothing that I could do, he had eye leukemia. I did some research online and saw lysine can help. He didn't like the paste but eats these treats right up. These do make his condition much better

    So Helpful by Leener02/23/2011

    My cats have a very common virus called herpes that they will always carry. Thank god I found out about lysine. A Yahoo group for feline herpes really has a lot of info about this. I give them these treats everyday to suppress it and it has helped them so much. They love the treats so it's easy.

    by woodlee from Ma.06/14/2012

    Vetri-Science Vetri-Lysine Plus - Soft Chews (120 chews) is an excellent product. It eliminates the mess of using a liquid or jell and the cat loves them. She thinks they are a treat. It has made giving her medicine a pleasure not a tough job.

    Great product, easy purchase by Susan11/18/2011

    I have used these for quite a while and was so happy to see them here for a lower price! They really do work - I have 2 cats, one with respiratory issues and these help stave off any major respiratory problems. Entirely Pets was easy to order from and I got my product quickly!

    He likes 'em! by KDLady07/29/2010

    My cat ate these right from the start. And he does not usually eat anything but his dry food. He even knows when to ask for them after dinner. I break them in half since they are kind of big.

    Fabulous find by Specks from Florida10/09/2011

    Great product. My cats devour it as though it was food. As soon as they hear the crinkle of the foil they line up for it.

    We buy these snacks here to treat our cats viral infection of the eye. My vet charges TWICE as much for the very same product.

    These treats are miracle workers. I have a cat that I adopted from the Humane Society that was always getting sick. I had to take her to the vet about every 2-3 months in addition to her shots. This got very expensive. Plus, she was on food that was $60 per 8lb bag and medicine that was $60/month.

    I have an elderly cat and a younger FIV+ cat that both require supplements to augment their immune systems; the FIV cat needs it and it's just good sense for the elderly cat.

    by The Clan from Delmar, NY04/30/2013

    My cats like these as special treats and they do seem to help with sneezing at times.

    Another good one by lilmcmac from orlando04/04/2013

    I have 5 cats all with different likes and dislikes. That being said, this is another way to get the ones who don't like Optixcare L-Lysine for Cats chews to take what they need. They are not as soft as the Optixcare, but they are smaller. My fussy little persian doesn't like these, but, she just like that. The others love it.

    My Cat Loves These by Sharon01/23/2012

    My vet recommended lysine twice a day for my cat Chloe. We tried the gel kind first, but it was messy and she didn't really like it. These soft chews are great, she thinks they are "treats" and meows for them.

    She likes it by gemcat from Brooklyn, NY08/12/2012

    My persian has battled herpes outbreaks since she was a kitten. She likes these! That's all I need to know. These help with the eye irritations, etc. Buying more.

    Paw-print seal of approval by Kim2012 from Chicago, IL11/11/2011

    My cat loves the Vetri-Lysine treats, which is a big compliment coming from this picky eater. The only drawback when compared to other L-lysine treats is that you need to feed 2 treats, compared to 1 treat with other brands. Good thing that isn't a problem with my picky eater!

    lysine for eye health by romeo from pittsburgh06/14/2012

    my cat would not eat anything with lysine gel in it and even managed to spit it out. so much for "palatable" on the label. these soft chews are eaten easily. i leave it on the mat with the food and water and he finishes it off each day.

    URI by Kris11/17/2011

    I use this for cats with Upper Respiratory issues.

    Love it!! by gidget from Oklahoma City04/01/2012

    I have 3 cats, and all 3 love these "treats". It is so much easier than the gel. Just wished they came in a bigger quantity.

    not for every cat by katlady from Fairless Hills,Pa02/08/2012

    This is an excellent product if your cat will eat them. I have 3 [three] and only my short hair eats them. This is fine because she had dry skin for years and after 4 weeks of eating these treats it has vanished and her coat is in the best shape since I have owned her. She was a rescue from my vet.

    Vetra Lysine Plus by Vetri-Science by Sharon from Dublin, Ohio03/03/2012

    Best selection of products and best pricing. My cats love this supplement, and actually beg for it. I have noticed an improvement in their general health since I have been using it.

    Great for all cats! by sadiecat from Charlotte, NC12/04/2011

    Our cats think these chewy vitamins are a treat, they like them so much. I have seen a huge difference in my 12 year old cat. She is more playful and lively! They have also helped her overrall help. Iwould highly reccomend these for all cats.

    by from 07/30/2012

    My cat developed feline herpes which caused an ulcer on one of his eyes. My vet said that he needed to take 500mg of lysine every day. We got through the first week or two with crushed up vitamins in can food, but usually, my guy eats dry. I found these chews online and ordered them immediately.

    Leo loves them by Sugar from Fort Collins, Colorado12/06/2012

    Leo loves to take his medicine. No hassle! My cat thinks they are treats! It is so convenient to order and receive them fast! Best thing I ever did, finding Entirely Pets!!!

    lysine+ soft chews by ecmck from DC05/30/2012

    My cat loves these chews. However, she can no longer eat them. She has no teeth, and these chews are not soft enough. Attempting to eat them causes her gums to bleed.

    Vetri-Lysine Plus by sidjes01/06/2013

    Great Product! My cats both take this product daily. It really helps!

    So much better than powder! by Jen from Beaverton, OR08/05/2012

    I used Lysine in a powder form that I got from my vet. My cat hated it and would do everything she could to eat around it, leaving much of it in her bowl. I found this about a month ago and have been giving it to her as directed (2 twice a day) for 3 weeks now. She LOVES them!!! And it is working. She has been sneezing less and less each day, almost no eye boogers anymore, and she isn't crying red tinged fluid.

    Allergy help by Whispurr07/03/2012

    My rescue kitty caught the sniffles from the shelter. I give four of these a day, in two servings, to keep her from becoming too sniffly. Wish they were 250mg each, instead of having to give two chews equalling 250mg. In other words, it would be nice if they were stronger.

    Lysine Chews by cat Manager10/30/2012

    Entirely Pets carries two varieties of Lysine Chews. We ordered the other variety first, and loved it. This one seemed to be half the cost, so we ordered this one. Not the case in the end. This one requires twice as many chews to get the same dose. But, the cat on Lysine (we have 8 cats) loves both varieties, and the cost is the same. I probably feel better with Vetri-Science Lysine since we have used their brand for so long with this cat. We were giving Barnstormer the jell, then went to tablets in pill pockets, and the cost of these is comparable to the pill pocket w/o the tablet. It made more sense to give him these (especially once he learned how to chew the pill pocket off the pill in order to get a second pill pocket!).

    my cat just love these treats by marcie61101/09/2012

    My 12 year old cat had the herpes virus as a kitten and I have been giving these treats to him daily which keeps him well.I would highly reccomend them.

    Lysine Treats by Cat Servant from Olympia, WA02/09/2012

    My kitties love their Lysine treats. These cost about half what the vet is charging when purchased through Entirely Pets. Will keep buying them this way!

    verti-lysine by kfogarty from Reno, NV12/06/2011

    This product is helping my cat's eyes. He has feline uviitis. The vet recommended lysine, but I couldn't get him to take it until I started giving him these chews.

    Great product by oct2497 from NJ12/06/2011

    I've had my cat on this product from the time she came to us off the street by our house. She was 5-6 months old & I started using this for her & she's been fine. Her eye has gotten a little bit better & does not tear as much as it did. I recommend it highly. Easy way to get them to take it too.

    Great product! by Neecy11/27/2011

    My cats clamor to eat these treats which makes it so much easier to give them the Lysine they need.

    Awesome item by Debdog from Huntington Beach, CA02/27/2012

    This item has really helped keep both of my cats immune system in balance.

    Stale Product by Diane05/14/2013

    Well this is a mixed review at best. I have ordered Lysine Plus from Entirely Pets in the past and had a favorable experience. My cat needs this product daily bc she has Feline Leukemia. However this last time, the product seemed old and stale,,,they are usually soft and easy for her to chew. Considerinig the cost involved I was very disappointed. I will look elsewhere.

    WHAT SERVICE! by ZAK from California01/21/2013

    Great PRODUCT I paid a couple bucks extra for 3-5 day shipping and the product actually arrived THE NEXT DAY! fantastic

    Tasty and Good for Them! by Cat Friend from NE Texas11/03/2012

    I was very relieved to see that all of my cats like the taste of this product and so will eat them. It's too soon to tell if the product is helping but the main thing is that it is getting into their systems so that it has a chance to help them!

    Best Product Ever by Foster98 from Cape Coral, FL11/08/2012

    I have an elderly cat who got so sick (due to the ignorance of a veteranarian) that he almost died. That was 6 years ago and these Lysine chews are amazing they keep my cat's resperatory issues under control, and he thinks they are treats. BONUS!!!

    by from 05/30/2011

    My 15 year old cat has been suffering from long-term sinus problems and has been sneezing goop all over the house at all hours for years (eww!), despite numerous courses of antibiotics. I read about lysine being good for chronic URIs and asked the vet about it, and she said to give it a try.

    Foster kitties love them by LPcatlady from Bentonville, AR07/10/2012

    Decided to give these lysine treats a try since the other brand Enisyl-F changed the shape (smaller) of their lysine treats. These treats are true treat size and the kitties love them. They actually smell good too. Plus I only have to give them 2 treats vs. several with the other brand.

    My cats LOVE these! by Julie361 from NC03/27/2013

    These are highly recommended, my cats run when they hear me pick and open this bag of treats. They're good for them and both cats have a beautiful healthy fur coat.

    by from 04/24/2013

    These are the only form of lysine that my cat will eat. She'll wake up from a dead sleep when she hears the bag open and anxiously await her "treat".

    I have been very satisfied with all the products that I have purchased from Entirely Pets, during the last year. Easy ordering process, speedy delivery and quality products!!

    Great for Shelter usage by Ronnie from Fairbanks, AK12/01/2011

    We use this during the winter months at our Shelter. We've found it really useful for preventing/ameliorating feline respiratory infections from getting worse. Best of all, the cats really like it so there is not a problem in dosing

    Great price by blnd1ab05/13/2012

    I usually spend about $25/bag to get these from my vet. How wonderful to order online and save almost 10/bag after shipping!

    Tasty tasty tasty by d'Artagnan's butler&maid from Santa Barbara, CA12/13/2011

    Recommended by vet. Fussy eater loves these! First time I have ever seen him race to food dish where he hears the crackle of the packet opening.

    Best Ever! For the price! by Mami from Chicato, IL10/31/2011

    My Cats Veterinarian thinks this is the best product ever invented. But he charges way too much $$ for this exact product. Cats with respiratory issues will often suffer from chest/nose congestion, sneeze and cough and they get as miserable as when we get the flu. These soft chewy fish shape treats are delicious to them and will take care of these symptoms. Also, contain DMG for immune system support. I have been using this product for about 2 years, Best of the Best Ever!! We love it!!

    Awesome Product! by Dana04/16/2012

    I have an elderly cat with stomatitis and he was continuing to have outbreaks every few months requiring antibotics and steriod injections. The lysine was actually given to me for his sneezing that was occurring upon completion of a course of antibiotics, however, I discovered that a daily dose of just one treat has kept him "outbreak free" for the last 1 1/2 years! It's easy to use, palatable to the cats, and what an inexpensive way to treat such a troublesome condition! I reccommend it highly for anyone that has a cat with a challeged immune system!!

    Best Price! by slp1921 from Massachusetts06/08/2012

    My vet charged me twice as much for the exact same product. My vet said that Vetri-Lysine is important for kittens because they are more prone to getting sick and this product is like a kitty version of echineacea.

    cats are crazy about it by Katzen from Toronto, ON, Canada11/09/2012

    for Herpes cats by Snooz03/12/2013

    I have a 3 year old cat that had a rough start in life and has herpes. He stays congested and his immune system is severely compromised. If he doesn't stay on these lysine chews (one a day) there's a good chance he'll spike a fever and need to go through a round of antibiotics and eye ointment. These are truly a life saver for him.

    Cleared chronic sneezing by Tess02/15/2012

    We tried these for my cat's chronic sneezing (after getting approval from our vet), and found they really helped to clear it up. Our cat loves the taste so they're easy to give, and they don't upset his sensitive stomach. So nice for him (and us) to get a break from all that sneezing!

    Lysine treats by Lynn from pgh, pa12/12/2011

    My kids love their "medicine" treats. I have to give them 2 x day and I have 2 cats and the deal I get thru Entirely Pets is so much cheaper than what I can get locally. Awesome!!!

    Easy way to get Lysine into my cats! by Karen from Pasadena, MD01/16/2013

    I have two cats that have bad outbreaks of the herpes virus. One has ocular and the other has upper respiratory issues due to the virus. Vet recommends lysine every day for each. This make it very easy to get it into them and they love them! It's a blessing for sure!

    Cat loves it and it's good for him! by Robin from Memphis, TN11/12/2012

    I purchased this product based on breeder's recommendation. I was worried my cat would not like it, but he comes running when he hears me open the package. He considers them a treat and I am so glad he eats them willingly.

    Wonderful product! by Lauren from Jacksonville,FL03/11/2012

    No problems getting my sometimes picky eater to eat these. She loves them! And they make such a difference in a matter of minutes. Wonderful product. A must have if your kitties have upper resp conditions!

    Great Service and Products by mmazanec from Galveston, TX01/16/2013

    Bought the Vetri-Lysine chews for our cats and I love making my purchases through Entirely Pets. They have a great website, prices, and the service is on point. A great experience overall.

    Vetri Lysine is a Boost for Persian Cats by trailwaif from Lake Elizbeth01/23/2012

    Helps with the breathing issues they normally have.

    Most Cat Friendly Lysine by msr from Baltimore, MD10/25/2011

    This is the easiest lysine to administer, all three cats love it, and it doesn't have lots of unwanted ingredients in it as many of the other lysine products have. Powdered lysine is difficult to dose properly because the cats steal each other's food and the paste type has ingredients I don't want my cats to eat, so this is the best. Even my cat who has no teeth can gobble them down. I just have to crumble them for her.

    Vetri-Lysine Chews by EireGirl05/02/2012

    My 6-year old female cat has been on these treats twice a day for about 3 months now. She loves the taste! Her veterinarian recommended the treats to help prevent her recurring respiratory infections. She hasn't been sick since she's been taking them, so I'm keeping my fingers crossed that the Lysine will help her long-term.

    Cassandra loves them! by Pak from Champlain, NY12/07/2012

    My cat, Cassandra, looks forward to her "treats" each day. She doesn't realize that she is taking her medicine. She has feline herpes virus and I use Verti-Lysine Plus (recommended by my Vet) to enable her immune system fight flare-ups of the virus. They are easy to chew and obviously delicious!

    This really works by Mami10/18/2010

    I have a cat with mega colon, herpes virus and spinal lesion and in just a brief time this has made such a difference with her physically and mentally because both her attitude and fur coat are precious. She loves the taste and I give her 2 daily. Definitely a great product for the money. Lysine is great, but so is the DMG, I give this to all my other cats since it is a great support for their immune system. Can't say enough........

    Lysine Treats by SilverGrandma05/12/2012

    Pet store in town doesn't carry lysine treats which I need for my cat, Ladybug. She has an eye problem and giving her lysine daily helps prevent flareups. Ordering from Entirely Pets helps eliminate the stress of finding and giving her the lysine. She loves the chicken flavored treats and eagerly eats (gulps) them. I definitely will continue to buy them from Entirely Pets.

    by donna from Cincinnati, OH02/08/2012

    I have order this product multiple times from the seller and have always received it quickly and without any problems. I will continue buying from them as it is the only thing we found that helps our cat.

    Our new kitty has feline herpes. I researched how to help him with it and found Vetri-Science Vetri-Lysine Plus soft chews. Within a few days of taking it he was much better. It has been serveral months now and he is sooo much better. He does not sound raspy in his breathing at all any more. also has not had a breakout since starting this product!

    Keeps our cat healthy! by Kumo from Arizona07/04/2010

    Our vet recommended these for our cat. She is 13yrs old and in the last year has gotten feline herpes. We aren't sure how she got it. She was on antibiotics for months at a time! Our vet told us to try these and she hasn't had a full blown sickness since. She sneezes and can't breathe at all when she gets sick. It seems to be worse in the summer for some reason. Now we just give her 2 chews 2 times a day and she's not sick! Besides the fact that she thinks she is getting treats all the time! Love this product!

    When my vet prescribed these, I was charged $30 for one bag of Vetriscience L-Lysine to treat his eye infection. Here, the cost was $12.99, less than half. The order ( I got two bags) came quickly. Cat's eyes are getting better. Thanks for allowing me to treat my cat without it costing so much!

    GOOD PRODUCT by KAT from Dearborn MichigaN02/06/2012

    Can cause allergies by Kitty Mom01/01/2013

    Please take care when using this product, as it can cause allergic reactions in cats. An older cat, with a history of food allergies, developed acute pancreatitis, and a younger cat, with no history of food allergies, developed recurring ear infections. Both cats required veterinary care and medications. Interestingly, their vet endorsed the use of this product, which was recommended by their breeder.

    These are very handy for the cat with herpes who doesn't medicate well. He thinks they're a snack and will run to catch them if I throw them. Some of my other cats beg for them who don't carry herpes but I share them anyway.

    Great, palatable immune booster by riorojo from High Point, NC10/09/2011

    Using these treats with DMG and Lysine for a rescue kitten with FeLV and FIV. We hoping to help him convert negative by boosting his natural immunity and excellent nutritional health. Tey are very palatable and soft enough that I can break them up in small pieces for him. I am also giving them to my adult cats to give them optimal health. My cats are treat finicky, and they LOVE them.

    VETRI-SCIENCE LYSINE PLUS SOFT CHEWS by PAULA from Wausau, WI 5440112/05/2011

    I have an extremely picky 12 year old Siamese Cat named Sam. Sam has a viral issue that is non curable in the nature of Feline Herpes. I used to try to give him the L-lysine pills that are created for humans. I would smash them up and sprinkle on his food. It was not affective becsaue he would eat around it. I then found these oills in the cat treat form but was so worreid abouyt paying for them and Sam not eating them becasue he is so picky. He will not even touch moist cat food or milk that is how pciky he is. But he loves these treats and eats them daily which I have seen a tremendous amount of increased time between his sneexing hacking snotty nose outbreaks~

    Seemed to help my cat by KJBATL from Atlanta, GA03/07/2013

    My cat had some slight sneezing due to a cold or allergies. After several days of the Vetri-Science Vetri-Lysine Plus treats, he improved dramatically and we did not even have to visit the vet. I'll always keep it on hand now.

    more than an immunity enhancer by zsazsa03/16/2013

    Originally recommended by my vet to enhance immunity in my 15 yr, old diabetic,hypothyroid cat. He loves them as a treat(something which he never ate before) and they seem to make him a livelier, more active and more affectionate cat. The price of 2 bags was less than what my vet charged for one.

    Great product at a great price by justabiggeek05/02/2012

    These were recommended for our cats as a daily supplement. I looked around the web and this was the most inexpensive place I could find that seemed reputable. We have been getting them from this site for a few years now and never had any issues with quality or shipping.

    Extremely helpful!! by SuzAnne02/25/2013

    My cat, Mia, who is a pure bread Bengal has had issues for many years with throwing up. We have gone to the Cat Clinic many many times to try to help her, and this is what finally has stopped her from throwing up. She loves getting her treats, and in return she is so much happier, as are we:) I would, and have, recommended this to friends with animals that have issues. I could not be happier with the results!! Thank you for having this product!!!

    Great product by Teri from Montclair, VA07/21/2012

    Vetri-Science L-Lysine Plus - Soft Chews (120) by Sandy10/26/2011

    All my cats love these chews! And the Lysine is especially helpful for my FIV+ cats. They get their L-Lysine every day and are super healthy :)

    Best service ever by Cebbie from Chicago, IL12/04/2012

    I have a cat with a compromised immune system and have been using this product for a while and it has helped him considerably.

    Best Purchase by Angel from Oregon02/04/2013

    Great product. Our 4 cats love it.Herpes virus symptoms gone.

    Cat loves these too by MAC from Verona, NJ01/11/2013

    My cat loves these treats too - easy way to boost their immune system.

    Loved By Tiger by Pauline from Phoenix, AZ11/14/2011

    I think it is a great product and will help my Tiger's eyes after he has taken them awhile. He loves the taste of them and can't wait to have them. Thanks for having the product available at a great price and speedy service.

    Awesome Product by Ardie08/11/2012

    My vet recommended Lysine for our kitten due to herpes virus in her eye. She was tiny and very sick and this product worked to help boost her immune system and it really helped. I give it to both of my cats and neither has had a flare up of the virus since. They love it too and think it is a treat!

    good value by nvgoodyear11/25/2011

    These chews are a good value and great if your cats like soft treats. I have 4 total that I need to give lysine once a day as a maintenance dose. 2 of them love the soft treats and will eat them right up. The other 2 will not eat them. But the 2 that wont eat them do not really eat treats anyway. So im back to the powder on the dry food for them.

    THE BEST LYSINE PRODUCT EVER!!! by Joni from Anchorage, AK04/30/2010

    This is the no-stress way to give your cat lysine. My boy is 24 pounds (fat, I know) and is now prone to URI's. I was having to force the gel down him - stressful for both of us, and the powder wasn't great for dry food. I give him 2 of these a day, and if he starts to sneeze - add another in, and it goes away! BUY THIS - YOU WILL NOT BE SORRY!!!

    by PK12/31/2011

    I highly recommend Vetri-Lysine Plus. My 2 cats get their "Lysine treats" before breakfast every morning.

    Works Great! by skhi10/28/2011

    I've been using this product for a long time. My cat loves it and its easy to use.

    Cat Vetri-Science Vetri-Lysine Plus-Soft Chews by keo10/11/2011

    Good - Helping clear a cloudy eye; however, not entirely clear. Cat must enjoy the taste because she always eats the two I give her twice daily.

    Cats wont eat these by Judester from Roseville, CA06/25/2013

    Based on other reviews I thought I would give these a try. The two Burmese that have the eye issues ignore them. They eat around them when they are placed in with their dry food or try to slip them into the canned.

    by from 07/10/2012

    My vet recommended I purchase Vetri-Science Vetri-Lysine Plus to help control my cat's watery eyes. This condition is caused by a compromised immune system that allows the eruption of Feline Herpes.

    by simi36 from New York11/06/2012

    This product has saved me from having to go to the vet for medication. I give him 2 chews twice a day and his eyes have been great and I'm not constantly paying the vet money for visits and medication. I did try other products but my cat did not like them and would not eat them. He has been eating these for several years now enjoys the taste.

    I only buy from Entirely Pets by foster9811/23/2011

    The website is easy to get around and the prices are the best I can find on the internet. The shipping is cheap and fast delivery. Communication on order status is consistent through the whole order/shipping process

    Verti Science Chews by Katie from Cleveland, OH11/16/2011

    Entirely Pets gave me great service in a timely manner. The product they sent me was exactly what I needed for my cats. They aim to please and they did that. Thank you!

    Well worth it! by JoyLee01/07/2011

    My cats LOVE the product. They actually beg for the chews as they do for their treats.

    Working product that cats like by Art and Patty from Duck, NC11/06/2011

    We have adopted several shelter cats with serious Respratory issues - this product has helped ease their problems breathing in many situations. We give 2 in the AM and 2 in the PM to each affected cat. They eat them better if they are broken up in to 2 to 3 pieces each.

    by Megz10/30/2011

    This was recommended by our vet to strengthen the immune system and health of one of our cats. It's working :)

    Love It by granofsam02/24/2012

    I Love this stuff I originally bought it for one of my cats who has herpes attacks and I also give them to my kitty who is frightened all the time she now comes to us and sits with us...

    by from 11/06/2012

    My cat has feline herpes, and our vet advised us to give him an L-Lysine supplement to help manage it. When he's normal, we give him 250 mg/day (so 2 chews), and double that to 500 mg/day when he starts to get an upper respiratory or eye infection. So far, we have been able to keep the flareups under control.

    Cat loved them by Diana from Kingsport, TN02/15/2012

    I have an older cat who has no teeth and is not very fond of the Lysine gel but the soft chews...he thinks he's getting treats. Will buy again.

    finicky cat approval by robyn from minnesota11/06/2012

    these seem to really help boost immunity and prevent symptoms of herpes virus. my picky cat looks forward to these every day.

    by from 01/29/2009

    I have one cat who never wanted to eat the Lysine paste that he needed to have due to Feline Herpes flare-ups causing him eye issues. I tried different brands of the paste, and while he didn't seem to *dislike* the pastes, he wouldn't eat them from the tubes or syringes like the other cats would.

    Fantastic Product by John K from Pittsburgh -Cranberry Twp, PA04/03/2013

    Works MUCH better & is WAY easier to use than anything you typically get from the vet. - A daily treat as opposed to cramming lysine gel from the vet down her throat...

    Vetri-lysine by Margie06/24/2012

    This product helps my male cat by keeping his eyes dry and he loves these 'cookies'.

    reduces herpes symptoms by Sue07/17/2011

    While working in a veterinary hospital, I brought this virus home on my clothes or shoes. Three of four of my cats came down with it. The oldest cat has continued to have flareups. These treats (which they love) seem to reduce to severity of the flareups. He still sneezes occasionally but not as bad. I would recommend them.

    Lysine keeps older cats healthy by laohu from Olympia, WA11/29/2011

    My vet recommended these to keep my older cats healthy and so far, they are. They LOVE these, as opposed to many other treats. These are their favorite which makes them effortless to administer.

    My cats love them! by SF AUTHOR from Naples, FL01/23/2010

    This is an easy and excellent way to get kitties to take their lysine. My two Maine Coon rescue kittens are FHV1 positive, and the gel Lysine from the other company (maple flavored? C'mon guys...seriously... when's the last time you saw a cat at IHOP ordering pancakes and syrup?) they hate. The powdered lysine mixes well in their food but for flare-ups, when I need to get extra lysine in them, this is a terrific product. I do moisten them when I get them so they're softer in a day or three, easier for the kittens to chew. I've also used them to disguise crushed pills--an easy way to get meds down the boys since they love the taste so much.

    Great immune system supplement by catmom3 from York, PA05/24/2011

    One of my cats was exposed as a kitten to a virus and had a compromised immune system. My vet told me about giving him these chews to boost his immune systems function. This seems to help a lot, because he hasn't been sick with kitty colds this year. Before, every winter all 3 of my cats would end up on vet antibiotics. Now they seem healthy.

    Cleared up cats symptoms! by minsnotux from Atlanta, GA10/12/2011

    This product has changed life for our 11 year old cat! No more sneezing, runny eyes and other symptoms. He likes this kind and brand the best compared to others we have tried.

    my cat loves them by cat from Maryland10/28/2011

    these are for my cat who has a constant runny nose. he loves these treats. too bad they cost $12 a bag...

    Sophie looks forward to her treats--two in the morning and two in the evening.

    Good product by LadyEm from Connecticut07/14/2012

    Unfortunately the cat I got it for is Miss Picky and won't eat them on a regular basis. The other cats love them! I'd definitely recommend them as a way to give Lysine to a cat that needs it and is less stubborn than mine!

    My cats LOVE these! by Liz from Los Angeles, CA10/25/2011

    These were recommended by my vet and my cats absolutely LOVE them! My 4-year-old cat stands by the cabinet and begs for them at night. I even have to hold her back as her brother (2-years-old) eats his, so she doesn't dart and steal them. I will keep buying them - and you should too!

    by from 05/30/2012

    My mom buys Lysine treats for me and I love them! She says they help me stay healthy and that you have the very best price and service. I think they taste great.

    Bought this product for cat with URI w/ suspected herpes strain. Gave to sick cat and healthy housemate cats. Sick cat got well and healthy cats stayed healthy. As an added bonus, the soft chews are GREAT for hiding my other cats pills in. All three cats go crazy for these chews. They must be tasty. Highly recommend.

    by Tricia12/05/2011

    Cats enjoy and it seems to help support their immune system.

    Bummer by DisasterDayGirl from Auburn, CA03/21/2013

    Unfortunately, the cat I got this for with the upper respiratory problem does not like "treats" of any nature. I suspect it is because he either can't smell or it is difficult to chew when he can't breathe though his nose. My other cats like them so I am giving it to them as a preventative.

    Exceptional Product by Tessicat01/07/2011

    As an RVT and owned-by of several special needs rescue cats, I've long known of L-lysine as an effective tool against feline herpesvirus. It saved one of my cats' eyes. I got a sample of Vetri-Lysine Plus at a vet conference and found it was the best way to get the full dose into a single cat, in a highly palatable treat. It's served as a preventative in a chronic FHV cat, but also works on the occasional sneezer to get them over their colds faster and avoid the need for antibiotics for a secondary infection.

    by Sander04/29/2010

    I have an indoor kitty and a feral cat that I feed and this Lysine product has literally saved their eyes. When they don't have it their eyes are weepy and look awful. I can just tell that this product works well for them. And wouldn't get this product from anyone else!

    No more struggle with meds! by janeausten_gonepostal12/12/2011

    I used to have to wrestle my poor feline to the ground, wrap her up in a towel and force compounded liquid lysine down her little throat with a syringe -- TWICE A DAY. Traumatic for both of us, to say the least. Can you imagine my relief when our vet recommended these yummy treats? Now the little angel actually BEGS for her morning and evening lysine dose, and the resulting improvement to our domestic tranquility is simply beyond description. This product, quite literally, has changed our lives.

    Cat loves! by Lady B from Sanford FL12/28/2011

    I used to crush up pills but with a fussy eater I knew she did not get enough. When I found these treat my life became much simpler! And she loves them!!!! The first bag I got I made the mistake of leaving it on the counter and she chewed a hole in the bag and ate a bunch... She also loves being the special kitty and having her very own daily treat the other cats don't get. I know some people compalined of them drying out but that does not seem to bother her & I just break them in half.

    1/2 the cost of the vet by redwinggirl from Detroit, MI11/24/2012

    I have a cat that has a very low immune system. My vet recommended these chews to help boost her immune system. My cat has taken two “treats” every day for over two years and hasn’t tired of them yet. My vet charged almost $33 for the exact same product. I made the mistake and bought them through my vet before researching Entirely Pets. Never again! My cat still suffers from infections, but that is due to underlying medical conditions. I honestly feel that these treats due help in the prevention of more infections.

    Great Service by Wallie from Spring Hill, Fl05/22/2013

    Easy to order. Good price, fast delivery and loved by my pet!

    Great product by Rosie12/30/2011

    I give this to my Maine coon Gidget twice a day. She has had problems with her immune system and low red blood count in the past, but after being on these for several months, I can see the change in her. Appetite is above normal and she is very active. Last blood work was normal. I'm sure it is because of these chews. Thank you.

    If your cat has herpes, put your cat on these lysine chews and your cat will be healthy.

    Good product by sunny from Ohio02/28/2013

    My cat was having several issue from allergies to low immunity issues. My vet reccomended these supplements and they were the first ones he would eat on his own like a treat even! As many cat owners already no it can be difficult getting your cat to eeat a supplement but he loves the taste of these and takes with no problems at all twice per day!

    Cats Love Them by abby2401/08/2012

    My cats absolutely love these treats-though I do have to break them in 1/3rds for them to eat more easily. Purchased these after my cats both had URI symptoms.

    Vetri is Very good by Lola from North Carolina03/15/2012

    My cat loves these! She is 14 and needs the vitamins. She's never refused them and I think they have improved her health and her coat.

    good for him by juliette from pittsburgh02/12/2012

    since our cat romeo really didnt like the gel lysine the chews seemed a good choice. for months he has gobbled a pill up once in the morning and once at nite. at the moment he seems to be on strike. it is my hope he will return to enjoying the chews since the lysine is recommended.

    Lysine by Spiderman from Charleston, SC05/01/2013

    My veternarian suggested using this for my cat who suffered from conjunctivitis each month since I adopted another cat. Since giving my cat this once a day, my cat this past month, did not get the conjunctivitis. I changed nothing else but adding the lysine. Hopefully this will help in continuing from getting it monthly.

    Verti-Lysine Chews by Tess05/24/2013

    These have really helped my cat who suffers from inflamed eyelids. They were so bad they were bleeding. And, he is difficult to give anything that he doesn't like. And he is extra big, so I have to give him an extra dose. These chews are saving me $ in vet bills.

    Excellent Product by Gary from Virginia03/18/2013

    My cat loves the Vetri[Lysine Plus-Soft Chews. This has helped with his runny eyes.

    MY CAT LOVES THEM by Tracy from Coventry, RI06/05/2010

    I highly recommend these!! My cat is extremely finicky even when it comes to treats. I was a little hesitant in getting these but decided to try them because I figured it would be the easiest way to get the Lysine in her. Well SHE ABSOLUTELY LOVES.....LOVES.....LOVES them, she even goes to the cabinet and meows for them. It's too funny. They are a little harder on the inside with the softness on the outside and soft enough for her liking. (The other only treats she would eat were just the opposite, hard on the outside and soft on the inside). So I guess she like the soft and hard combination. I also like these because you only need to give two treats as opposed to five or six.

    Great purchase by KATLADY from Levittown,Pa01/24/2013

    This is excellent to "pump up" the immune system of feral cats. I feed this along with the powder form to my 2 colonies
