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

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.
