Our 18 yo kitty has had diarrhea for probably a year now. We finally took him to a new vet for a second opinion and they were much more pro-active. The vet said it might be IBS (which I find is usually a blanket statement for tummy problems) and prescribed Science Diet z/d. If this helps Moocher we'll keep him on it, but I'd really prefer a better quality food, especially if we're dishing out the money anyway. Anyone have suggestions for a similar food to z/d, but a better one?
Also, any ideas other than IBS for why he might have constant diarrhea? We've had every test in the book run, all levels are normal.
