Hi, this is Lynda, and my Martha has several issues---now looking like diabetes on top of the rest. Nutrition-wise, she is presently doing well on Hills' Prescription Diet food---I/D and K/D dry cat(2)_steam -- and I/D and Z/D canned, also another she loves is IAms prescription Low Residue. It's important that I watch ingredients and esp. Phosphorus with these illnesses. BUT I'm learning I've got to start getting those CARBS down! I know the dry food is especially bad, but I have to feed this baby what she will eat. In honesty, I have been working to get her off dry food. It's slow coming. Martha is also a little fattie, (my bowling ball with legs!) so I'm working at getting the weight down too. She has tried the hills canned diabetic formula but doesn't care for it. Does anyone else have CRF/IBD/diabetic kitties? And what do you feed them? Blessings, Lynda, Martha, and Angel C.B.
