KAK, my own vet also told me (when I spoke about Jasper's diarrhea) that getting a cat like my Jasper, or your Starr, OFF pred. entirely, was highly unlikely. But the good news is, that (at least in Jasper's case) we've had no diarrhea or accidents in quite a while. Hoping you see the same results with Starr.

Oh, BTW, Jasper has also been eating the Innova Evo dry food. It seems to agree with him.
