Mink are dark-colored, semiaquatic, carnivorous mammals of the genera Neogale and Mustela and part of the family Mustelidae, which also includes weasels, otters, and ferrets. There are two extant species referred to as “mink”: the American mink and the European mink. The extinct sea mink was related to the American mink but was much larger.

The American mink’s fur has been highly prized for use in clothing. Their treatment on fur farms has been a focus of animal rights and animal welfare^[1] activism. American mink have established populations in Europe (including Great Britain and Denmark) and South America. Some people believe this happened after the animals were released from mink farms by animal rights activists, or otherwise escaped from captivity.^[2][3] In the UK, under the Wildlife and Countryside Act 1981, it is illegal to release mink into the wild.^[4] In some countries, any live mink caught in traps must be humanely killed.^[5]
