Q. My cat has megacolon and is on cisapride and lactulose. He does not like the prescription weight management food. Is GI prescr food ok?
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. It depends upon the exact GI diet you're considering. If you're talking about Royal Canin's gastrointestinal food, many vets do use it for megacolon cats. However, it's a prescription diet so you'll have to get your vet's OK to purchase this food. Another strategy many vets use for managing megacolon cats is to feed a high quality canned diet. Iams Low Residue is a good food for these cats, and feeding canned food increases the water content in the diet dramatically, contributing to softer stools which are easier for these cats to pass.
