How to fatten up a cat

[aTailOf2Kitties]

I could swear I saw a food specifically for diabetic cats. I'll do some digging and see if I can find it. I know Eukanuba used to have a glucose-control dog food.

Edit: Purina DM is made for diabetic cats. Not sure where you can find it. It comes in canned and dry varieties.

Did you see this web site specifically for diabetic felines.
