They are well Domesticated and are not wild at all. In fact, in approximately 3000 B.C. Egyptian pharaohs domesticated the ferret. The Crusaders of the 11th century then introduced the ferret to Europe, where they were trained to hunt rabbits. Once in Europe they cross-bred with the European polecat, eventually producing the ferrets kept today as pets. They were used extensively on ships, as they are still better mousers and ratters than perhaps any other animal.
Ferrets can get along with other pets and even with children.
