The fat cat with holes in his belly. He has pulled most of the hair out in two spots on his belly, and he bites holes in himself - OCD at its finest I suppose. We wanted to rule out a food allergy so we switched our babies to a better cat food just to make sure. We now feed them canned food made of 95% meat, all human grade, no corn, soy or wheat... it nearly quadrupled the amount of money we spend, but they're our babies. They're worth it.
