I have two ferrets, both 5 years old, and ever since I've had them one will bite-and hang onto- the neck of the other. They've done this for over 4 years; we find them just hanging out with the same one always doing the bite and clamp thing. No one is hurt and there are no marks, they just seem to like to do this. We're getting close to the time ferrets get their winter coats, and I'm finding that the fur of the one who is bitten is getting a bit thinner around his neck. Has anyone else had this experience with their ferrets? I'm wondering if the fur will grow back in with the coat change. I'm also wondering about separating them, but they are the best buddies.
