John Rosloot: One solution that I have heard of, though I have never used it myself, is to bite them back when they bite you. A firm nip on one of their ears I hear will give them the message. This probably has something to do with the dominance struggle that ferrets seem to go through. Also since biting is a natural part of their play they have learn that they can't be as rough with their 2 legged friends as they can with their 4 legged ones. or what it's worth.
