Native to Europe from the Mediterranean to Scandinavia, ferrets are slender-bodied, carnivorous mammals. The ferret is a descendant of the polecat and a member of the mustelid family, which includes stoats, weasels, badgers, skunks, otters and minks.

Ferrets have naturalised in many places, including New Zealand, Morocco, and parts of the USA. They are associated with declines in native wildlife populations in New Zealand. Up to 150,000 ferrets are kept as pets in Australia. However, ferrets are prohibited as pets in Queensland and the Northern Territory.

The ferret is a prohibited invasive animal under the Biosecurity Act 2014.
