I have two ferrets-one is very skinny, about 1 year old, and the other is very fat, about 7 months old. In fact, the fat one is so big that I had the vet check her because of her weight, but she tested negative for diabetes, and the vet figured it was just her metabolism. Both ferrets eat Kaytee Rainbow Diet, and are given ferret-vite and 3 Kaytee treats a day. My question is this: should I be worried about the skinny ferret? She seems to eat okay, but definitely not as much as her buddy. When people come over to my house, they often comment on the extreme difference in their weights. My next question is if anyone has any suggestions to bring the thin one's weight up-I just started letting her have some Iams Kitten Food to try to bring up her weight, but their is no difference so far. I would appreciate any responses on the subject! [Posted in FML issue 2730]
