QOP, I think you can check if they have MF tattoos in their ears...?

Pit Chick, I so agree! I've heard so many horror stories about MF, I would only buy from reputable breeders or adopt rescues. Our two boys now are rescued, they're brothers from MF.

Maybe you should offer some advice to the "rescue" group? sometimes people are completely oblivious to how pets should be treated, they might not know the care that ferrets require. Some constructive criticism might wake them up?...
