Ferrets were once banned in many US states, but most of these laws were rescinded in the 1980s and 1990s as ferrets became popular pets. Ferrets are still illegal in California under Fish and Game Code Section 2118; and the California Code of Regulations, although it is not illegal for veterinarians in the state to treat ferrets kept as pets. In November 1995, ferret proponents asked the California Fish and Game Commission to remove the domesticated ferret from the restrictive wildlife list. Under the Common Law, ferrets are deemed "wild animals" subject to strict liability for injuries they cause, but in several states statutory law has overruled the common law, deeming ferrets "domestic."
