Domestic or European ferrets are carnivorous mammals related to weasels, minks, otters and skunks. They have long bodies, short legs and thick fur with various color patterns. The natural pattern, called sable or fitch, features a yellowish coat with dark patches over the limbs and tail, a facial mask and dark brown eyes. Ferrets have anal scent glands and sebaceous glands but lack sweat glands and hence are particularly susceptible to heat.Lab Anim. (NY) 41, 217 (2012).
