I don't know any breeders. But I used to work in a pet store and Ferrets can have a MAJOR temper problem. About 75% of them were in dire need of taming. Because their bites really hurt lol
But honestly, they're so cute and if you don't mind putting in the time it takes to tame down an animal. Go for it. And good luck.
