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.

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 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

Felisyl by Kazuye from Los Angeles08/17/2014

My cat caught the herpes virus while a kitten at the animal shelter. Felisyl helps her from getting so much sneezing and stuffy nose symptoms. I mix it into her food everyday and she doesn't mind it at all.

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.

great product by dustyj from austin, TX02/26/2014

I have a cat with a chronically irritated eye and she is also FIV positive. My veterinarian had suggested l-lysine to help decrease the viral load and she suggested this. I sprinkle some on a bit of wet food or spray water on her dry food and sprinkle some on it. She gets her doses twice a day - no hassle.

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.

Felisyl Immune System Support by I don't have a nickname from North Carolina07/01/2013

The cats like it, Use it to help keep foster kitties healthy.

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.

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!

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.

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.

Excellent purchase price by cati from Kansas08/07/2013

This L-Lysine HCI supplement for cats is less expensive than the vet recommended Viralys. So far, it has been just as effective to address herpes in my cats. The best part about Felisyl is that the cats actually eat it readily when mixed with canned cat food.

not just for feline herpes by mindymoon12/14/2013

I took in a very sick stray 3 years ago He had an upper respiratory infection so severe that 3 different vets weren't sure he would make it. He also tested positive for Feline HIV. Vet suggested Viralys for immune support. I've had him on Felisyl for 3 years. After months of TLC and antibiotics, he got healthy and gained weight. His coat is beautiful, eyes and ears clear. And he has stayed very healthy since. I think the Felisyl helps, so will continue it for the rest of his life. I add a scoop to his wet food once a day.

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.

by Kazi's Mom06/07/2013

This product has done a good job keeping my kitties from having feline herpes return. It is a good immune system builder.

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!

by I don't have a nickname from North Carolina06/16/2013

Have used this before. It helps the immune system in kitties.

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

by from 12/20/2012

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.

My cats love it by Ely03/19/2013

I have two cats with herpes of the eye and both are happy to take 1 tab each am and pm.

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.

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!

SERVICE by Cindy01/17/2015

After not receiving the product for weeks after my order this time...I called and was told it was back ordered with no expectation of delivery date. I cancelled the order and went to 1-800-pet meds. My cats needed that and it was detrimental to their health to have had to wait without any idea it was not available !!

Most Economical by Cindy from South Carolina11/01/2013

My vet had quoted me an outrageous price for Lysine when my cats came down with a herpes virus. This product keeps them symptom free at a fraction of the cost!

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.

by Mar from Loudon,TN12/01/2011

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.

he won't eat them... by puzzled1 from new york city09/11/2014

even if I break them up into tiny pieces. They're not soft enough for my old guy. I found another brand that are softer and he'll eat those.

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.

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!

by Anita03/16/2013

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.

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.

wonderful by Neeter06/11/2012

Our cats really love them...no trouble getting them down...great for when I am not feeding wet food...

better flavor please by Shelly from Bakersfield,CA01/22/2015

I loved the dosage size but my cats do not like the flavor. 4 cats out of 4 say blaa! I haven't given up on them acquiring a taste for it but it is becoming a battle. It looks like I will have to mix it with food and that's no fun for me. Outside of that issue I would buy it again.
