My non-diabetic kitty, Chloe, is in obvious pain. She is constantly licking her bottom and crying. The vet says because she is overweight she has a hard time cleaning herself and the accumulation of fecal material on her bottom is what's bothering her. He recommended we clean her with baby wipes. We try, but she howls in pain. I think all of this is due to changing her diet. When Sasha was diagnosed with diabetes we switched both cats to Fancy Feast Classic and Purina DM dry. She never had any problems with her bottom on the old food, even though she was overweight. I'm thinking one of these new foods is making her stool more acidic. Does anyone have any similar experiences?
