I have 3 ferrets that are on Kay-Tee and I mix ferretone in with that. They are very particular, won't eat Marshalls or 8 in 1. When I got my third baby yesterday, I talked to the breeder about their food. He said to feed high quality cat food to the ferrets and that since they are spayed they don't need a high amount of protein. He hasn't had any trouble with tumors (I have). Do they really need less protein? How does the Kay-Tee nutrients compare to others? Thanks for your help, Nancy Abby - I'm feeling so much better! Ginny- GET THIS LITTLE RUG RAT AWAY FROM ME!!!
