Does anyone know a good place to get this relatively inexpensively? I keep Oogie on it because of the bad respitory infection he had when I rescued him - The vet said he didn't have herpes, yet if I take him off the Lysine, he starts getting snotty again. I'm keeping Haley on it as well just for the heck of it - And with a 3rd Sphynx joining the family soon, I'm looking for somewhere to either buy it in bulk to save a little money, or find it a little cheaper then I'm getting it from my vet for. Anyone have a good source? Is Lysine safe for kittens (he'll be 12 weeks when I bring him home)?
