Felisyl Immune System Support for Cats is a safe nutritional supplement for your cat if it has a condition that is responsive to L-lysine. L-lysine has been known to reduce the harshness and number of occurrences of herpes simplex viral infections. These infections result in fever blisters and cold sores. L-lysine is an effective ingredient of Felisyl Immune System Support for Cats. In cats, the herpes virus is considered very contagious. What makes it so problematic is that it is a very common cause of upper respiratory infections (URIs). Symptoms of URIs include eye discharge and sinus congestion in your cat. You may also notice some squinting of the eyes and sneezing as part of the effects of an upper respiratory infection. Felisyl Immune System Support for Cats can help. Felisyl is an easy to use nutritional supplement that kittens and cats alike seem to find tasty. It is easy to administer by simply mixing it in with their cat food. Other benefits to Felisyl Immune System Support for Cats are that it helps promote healthy tissue, encourages respiratory health, and can even help with your cat’s vision. It is effective, easy to administer, and has some nice additional healthy side effects. Administration: Approximately 1 to 2 Soft Chew L-Lysine daily.
I purchased these as back up in case I run out of the Enisyl-F paste. The kitties love them so I think it's a good alternative to the paste. Only problem was some of them were broken up so it affects the proper dosage.
UPDATE to previous review on Felisyl by MrsD. from PA12/21/2012
The replacement shipment that EP's was kind enough to send to me, was just as bad as the original order I bought of these. I did notice the lot numbers & expiration date, were the same on the replacements as they are on my orginal order, making me believe this might be an inferior batch from the company who makes these. Both shipments of Felisyl I received, were very light tan in color & as hard as a rock. Nothing at all like the dark brown soft treat they used to be. I hope the compnay who makes these treats doesn't plan to make them the way I received them, because I will not be buying them anymore if they do.
Great product! by Kim2012 from Chicago, IL11/11/2011
I had been crushing up L-lysine pills and mixing them in my cat's food until I found Felisyl L-lysine chews. Now I don't have to worry about my cat getting the correct dosage if he doesn't eat all his food. He loves these treats, which is a big compliment coming from this picky Burmese boy!
Product smelled rancid, cats would not touch.
Good for the kitties :o) by GreenBee from East coast of Iowa01/16/2013
Several years ago we adopted two kittens who had upper respitory issues. Our vet suggested trying L-Lysine. It helped get them healthy (I believe) and I really think by keeping them on the L-Lysine it helps keep them healthy.
Wont purchase again. by MrsD from PA01/09/2013
The last 2 shipments of Felisyl were nothing at all like the product I used to get. EP's was kind enough to send me a replacement order to see if I just got a defective batch, but the new batch was just as bad. The treats used to be a very dark brown & very soft, but the 2 batches I received were a light tan & hard as a rock, & smelled nothing like they once did. I was not going to feed my kitties these Lysine treats; when they looked & smelled totally different from how they once did. I dont know if the manufacturer of these treats changed the formulation or not, but I will never buy them again. Kudo's to EP's for their excellent & prompt customer service in resolving this issue.
Great product! by Joan from St. Joe, Michigan04/22/2013
Felisyl (l-lysine) works wonders for kittens vulnerable to upper respiratory infections and cats with eye issues. I give daily as a treat and it keeps them from visiting the vet.
Great for Cats Missing Teeth by LindaD303 from Northglenn, CO04/03/2012
My Siamese cat is missing all of his chewing teeth and these chews are soft enough for him to eat. He's a very picky eater and likes the flavor of these chews. I have noticed that he has less eye discharge with the lysine supplement in these.
Only a few of my cats liked the taste of this. I won't be buying it again.
Huge disappointment this time around. by MrsD from Erie, PA12/11/2012
I have bought these treats many times & never had a product issue with them, until my recent order came. I ordered 3 bags, & ALL 3 bags were nothing like these treats usually are! The treats were as hard as a rock, a very light tan in color; as opposed to the dark brown color they are supposed to be, & they had an odd; almost rancid odor to them. The expiration date reads 1/2014, but no way are these fresh! Kudo's to Entirely Pets for immediately offering to send me 3 replacement bags! Their customer service is as always, fantastic. I hope the new bags will be alright.
Best Purchase Ever by Angel01/21/2013
Great product. Our 4 cats love these. They keep the symptoms of the herpes virus away.
Great for feline eye infection by Gina from New Orleans, LA06/07/2012
my vet recommended lysine for Max's eye infection and it has cleared it up. He loves the treats and begs me for them each morning. Much better than the power you sprinkle on their food because you know he is getting the exact amount he needs
Best purchase for my cat by BABS from FL12/02/2012
My cat Lilly has upper resp. disease.
She is responding well to Felisyl Immune
System Support soft chews. Sneezing and
sniffles has decreased. Have already purchased
6 more packages. I would recommend this
Value by Cindy from South Carolina12/05/2012
This is a great value. One soft chew a day and my cats are healthy and it is very cost effective.
cats like them by gloworm from Alabama01/20/2013
My cats like this treat and it is an easy way for them to get their medicine
My cats love them by SnapLilly06/10/2012
I usually get the Enisyl-F Lysine treats, but they were out this time. I decided to try the Felisyl. You only need 1 or two and both my cats love them. They are about the same price but you can give them less. They are more like a soft treat the others are a little harder. No complaints from the cats and they will not eat anything they do not like.
Great L-Lysine Treats by Mitch from Pittsburgh, PA02/07/2013

good flavor by vikka's mom from upstate New York12/14/2012
We have 4 cats on L-Lysine. The treats make it much easier to administer than pills or powder. All the cats like the the flavor of Felisyl .
I have two cats with herpes of the eye and both are happy to take 1 tab each am and pm.
My Cats Do Not Like These by Christine01/29/2013
I thought I would try these Lysine Treats becasue the price was much better than the Enisyl-F Lysine Treats. My one cat will not eat them & my other cat throws them up right after. I would not recommend them if you cat is picky or has a sensitive stomach.
Helped my cat a lot! by RaIrCo2412/06/2012
My cat had sores from her feline herpes and Felisyl helped a lot to let them heal and go away. Glad I purchased this.
Felisyl L-lysine by Joan from Michigan01/02/2012
I have used L-lysine for my cats with eye issues for about 2 years. I recently found this product and use is regularly as it keep their eyes clear and helps with irritation from herpes virus. This product is soft so was helpful for my friend who has an elderly cat who does not tolerate the hard treats. He also has had success with this product. I strongly recommend!
GREAT discovery by Carol from Ft Lauderdale Fl05/30/2012
The cats don't know there's medicine in the chews, they think its a treat! They eat them up fast. I try and hide an Anixtane tablet in between 2 of the chews. Someone should make a pill pocket out of the soft chews.
by from 02/23/2012
I recently purchased 3 packs of the Felisyl Immune System Support upon the reccomendation of my vet. Allof my 5 cats enjoy them and come running when I open the bag. It's still too early to determine the full effect, but I'm planning to keep feeding this product as a part of their daily diet.

I am giving the Felisyl lysine to 2 of my cats. They are not crazy about the treats but will eat them & that is all I ask. Too early to tell if lysine is helping the herpes.
Our cats really love them...no trouble getting them down...great for when I am not feeding wet food...
by from 04/24/2013
Last winter I purchased a three pack. My cats loved them. They were "fish" flavored, dark colored and moist.
I recently received a six pack shipment. These are chicken flavored, beige tan and harder. All three cats turn up their noses and walk away.

My "go to" Lysine chews by Heidibear03/25/2013
I have rescue cats and some have "eye" issues and benefit from Lysine. Well, there are many forms of Lysine out now, thank goodness but all of the ones my cats are supposed to like...they don't! They are so difficult!! Anyway, These chews are the most moist you can get and are easy to chew. I just widh they had more Lysine per chew, and for that I would add the 5th star! Can't have it all though huh? Thank you!
This is an excellent product but the last couple of batches have been hard not soft and my cats won't eat it....I sent emails about that and they are supposed to be sending some out to replace the last ones I got...but this batch is hard too....
One of the Best purchases ever. by BABS from FL12/08/2012
My Cat Lilly is doing good on this product
her sniffles and sneezing are lessoning.
It is much easier to give her the treat.
Though I must cut it in three pieces and
put it with some of her other treats.
Its much simpler to get her to eat her
immune support soft chew. That is why
I reordered 6 more packages. She is currently
doing well on 3 treats a day. She is also
much more alert and active. with her upper
resputory illmess.I would recommend this
product to other cat lovers. Try it.
This product helped my cat conquer his sinus condition better than a whole series of antibiotics. It seemed to greatly improve his immune system.
Works very well by moms_2slow from Wilton, CA08/16/2012
This product has a very yeasty smell, so my cat loves it. He has slowly improved on the product, so I am quite happy.
by Katzhse from Tucson, Az11/24/2012
I have been sprinkling this on their dry food so at least they get some when they eat. If i put it in the wet food they won't eat it.
my cats love this by Karen11/30/2012
this product is very palatable, one of my cats even tries to lick it right out of the jar!
Good stuff! by Kaye6311/13/2012
My cats loved this and I will be ordering it again!
oral powder by Anita10/24/2012
This works well mixed with wet food...we do have a couple that will eat it right out of the bowl before the food is added....it does a good job of helping to control virus'
Felisyl by Sandy from New York12/14/2012
Used the product for my cats who were sneezing and it seemed to help them a bit. Their eyes are no longer dripping as they were, so perhaps it works as stated.
Felisyl Immune System Support by Queen B from New Castle, DE11/23/2012
It seems to work as well as other brands. It dissolves better in food than other brands. It's slightly cheaper, however, I believe the dose is slightly larger.
product probably fine but the cat won't get near i by max's mom from west palm beach04/05/2012
They say it is flavorless and odorless. The cat doesn't think so. Right now I am back to crushing human lysine tabs and then mixing them into soft food to hide it. Right now, that is fine but may try sneaking this into his soft food again soon to save me the trouble of mashing his pills. Too early to tell how this will work.
Felisyl by jj05/20/2013
works really great it really helped and looking forward to ordering more in the future
by from 03/04/2012
My cat does not like "treats" so I bought the powder version of Felisyl and put it in his food. He does not know the difference and he eats it! YEAH!!! No force feeding!!!! Something you do not want to do with a cat. (CLAWS)

I give this to my 4 cats on a daily basis. Very pleased with results.
by Benji's mom03/04/2012
The cat loves his food with sprinkles of FeliSyl on top and has zero hair balls if given daily.
Good product by Dawn from New York, NY03/10/2012
I used to buy a more expensive brand, then found this one. The color turned me off a little (I'm used to a white powder), but my cat doesn't know the difference and I have no problem putting it in her food.
Not the answer by Pauladimi from Las Vegas Nevada02/26/2013
I have cat with diabetes and allergies. it does not help him at all. I was hoping to avoid going to the vet and getting him a steroid shot
This product has done a good job keeping my kitties from having feline herpes return. It is a good immune system builder.
by from 04/10/2012
My vet told me to add lysine to my cat's food. He had a herpes infection when I rescued him. The lysine is supposed to help recurrences and thus far Simon has had none.

great stuff by fostercatmom from Indianapolis, IN08/19/2012
I have volunteered with an animal shelter for over 10 years. We put lysine on the food of all the cats because it helps with the herpes virus that runs through all shelters. It doesn't cure the virus, just helps to keep it from replicating. This version is flavored and the cats like it.
by Cat Lady03/23/2012
Have had the cats on this for years to keep down the symptoms of the kitty herpes type illness. They like the taste and it works well. Much easier to use than the paste and more economical too.
Great product by DustyJ from elgin tx06/15/2013
Cats like the lysine powder (all 9 of them) - a first! easy to put on wet or dry food. I use a slight spray mist of water which helps the powder stay attached to the dry food and voila it is eaten without problems
Very nice product by vj from IN12/14/2012
My cats must like the taste because they eat it up when I sprinkle it on their food!
This is Great Stuff! by annetta from kansas03/29/2013
Felisyl helps the immune system of cats. My cats have frequent sneezing and it takes care of it. Likely the vet said it's probably from cat herpes. But many cats have this. Any time a respitory problem...cold or stuff like that starts...give them felisyl. It's best to not give daily unless your cat has a severe or ongoing problem. It works for my babies and it may likely make your vet trips much less needed.
Felisyl recommended by my vet by Tutti from Los Angeles02/06/2013
Great product especially for those of us that have more than 1 cat because you can use it every day in their food and it strengthens their ammune system. I am on my 4th container. Entirely Pets has the best price according to my vet.
My cat liked the Viralys better by MaryAnnSanDiego from San Diego, CA07/06/2011
I had been using the Viralys powder for about a year with no problem. Just decided to try the Felisyl since it was a little cheaper. My cat backs away from ANY food I put down with the Felisyl mixed in. Eventually after complaining for a while, she will eat! I will go back to the Viralys so I won't have any food issues. Both products seem to work the same, however.
good value by Tuxcats12/17/2012
There are other L-Lysine products, same ingredients, at a higher cost, on the market, and at the Vet's office. Happy with product, price, and great service.
I have four indoor kitties and we were constantly having upper respiratory infections. My vet suggested that I put them on Llysine to help with the symptoms. The cost was exorbitant to say the least. So I started looking around and found Entirely Pets.

Have used this before. It helps the immune system in kitties.
It really makes a difference! by Rae from Memphis, TN04/27/2011
My Siamese cat has a bad case of herpes, because she was left untreated for so long before she was adopted which means she will always show some symptoms no matter how good the medicine is. We tried other brands of lysine powder and pastes that cost more money than the Felisyl, such as Viralys. None of them made the difference that Felisyl made for our cat. She has less frequent eye watering and sneezing compared to the other brands. She seems happier and more full of life!
My Cats Love This by Karen from Outer Banks, NC04/01/2013
I have several rescued cats that take l lysine. This is the one product that they all love, I can just sprinkle it on their food and down it goes. One kitty won't even eat unless her food has it! highly recommend
