Biting is part of the natural behavior of ferrets. They may bite to get attention or as part of play. This is particularly true of young males 3 to 4 months of age that have spent most of their lives in a pet shop with other ferrets but little human interaction. Ferrets may play with humans in the same rough manner they play with other ferrets. If your ferret nips at you, return it to its cage for a brief “time-out” period. Done consistently, the animal will learn that biting is not appropriate behavior.
