According to what I've read, cats with IBD can go off of the preds slowly & then only need it for flare-ups. I'm not really sure what to do. He has a re-check with the vet on Sept 5th. I might try a little on the preds & then see what she says to do then. I've got both wet & dry . . . I can't even get him to try the dry until next monday anyway. I had to have them order it.
