Wow. I've never had a problem with ferrets, owned several of them and assisted in the purchase/care of dozens. Just like baby snakes they can be nippy. But all of the ones I kept never drew blood. They might nibble on me or play a little rough but I never had a problem with a ferret that bit. Dunno maybe the breeders didn't raise them right.
Snakes? I just like to teraform!
