Easy to mix in food. My cat doesn't like "Pet Naturals of Vermont, L-Lysine" any more after she finished one pack. I mix with wet cat food and she eat it. Yeah!

Thanks for your feedback!

L-Lysine was recommended by a vet to help a feral cat in our backyard fight an upper respiratory infection. I sprinkle it on his food, he doesn't mind it at all and eats every bite. About 2-3 weeks after I started giving him Lysine I noticed a decrease in the thick discharge from his nose and eyes. Now, few weeks later, his face is clean, he moves around the neighborhood, and looks healthy. Prior to the Lysine he spent all his time sitting under a bush, face covered in snot, audibly gurgling trying to breathe. He did not move more than a few feet.
