Felisyl Immune System Support

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

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.
not just for feline herpes
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 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.
Felisyl recommended by my vet

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
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.

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

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.

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.
This is Great Stuff!
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.

This product has done a good job keeping my kitties from having feline herpes return. It is a good immune system builder.
Excellent purchase price
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.
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.
Very nice product
My cats must like the taste because they eat it up when I sprinkle it on their food!
