The ferret is a small, domesticated species belonging to the family Mustelidae. The ferret is most likely a domesticated form of the wild European polecat, evidenced by their interfertility. Other mustelids include the stoat, badger and mink. They're part of the mustelidae family, which includes otters, stoats, weasels and badgers. They have been used for hunting and pest control for a long time and are still kept for this purpose today, though they're becoming increasingly popular as pets.
