OK, I'm sure I've asked this before and I know my vet has told me at least once, but I keep forgetting. How much L-Lysine do you give a cat? Jordan's viral eye problem has flared up again & I'm almost out of the stuff the vet gave me last summer when he was sick. Usually I can get it under control in a couple days, but just incase I wanted to know how much L-Lysine I could give him.
