latches on big time, none of the rest of the pack are like it, it's a bit of a nuisance having a biter, as I have to watch her with the grandkidsI agree that biters don`t stay very long but sometimes the reason could be medical. A tooth problem or an internal stomach/chest problem has been known. Many years ago I had one that bit at any opportunity when picked up, it turned out that she had a growth in her chest that was extremely uncomfortable when she was picked up.I've kept ferrets for seventy years and still stick to the rule if they bite they go! I've never seen the point of keeping biters, if you can't handle them with confidence they're just not worth keeping. You will also find that occasionally if the jills bite, the offspring will do the same.
As a rule if kits are handled from when they are really young apart from "play" biting when they are getting their adult teeth youb shouldn't have any trouble with biters.
