The ferret, a popular house pet, is a domesticated descendant of the polecat. Cross-breeding of ferrets with its wild ancestor produced the ferret-polecat. This hybrid is often used for hunting rabbits. Sometimes they escape during a hunt and are able to survive well in the wild. The ferret-polecats which have escaped from captivity usually live in rabbit holes. They will eat all kinds of small animals and eggs. Sometimes, they build up a food supply of live frogs which they bite in the neck to paralyze. Chickens and rabbit cages are also favorite foraging grounds for the ferret.
