The ferret (Mustela putorius furo) is a domestic pet. It is not a wild animal, though ferrets are descendants of the European polecat (weasel) and are, therefore, close relatives of skunks, mink, otters and badgers.
Types and Terms: There are 2 varieties of ferrets, based on coloration. Fitch ferrets (the most popular) are buff-colored, with black masks, feet and tails. Albino ferrets are white, with pink eyes. The female ferret is called a "jill,” while the male is called a "hob." Babies are "kits."
Physiology: The gestation period of ferrets is 42 to 44 days (average, 42 days). The average litter size is 8 (range, 2-17). Kits are born deaf, with their eyes closed. Their eyes open and they begin to hear between 3 and 5 weeks of age. Their deciduous ("temporary") teeth begin to erupt at 2 weeks of age, at which time they begin to eat solid food. Kits generally are weaned onto commercial kitten chow at around 8 weeks of age. Kits reach their adult weight at 4 months of age. Males are typically twice the size of females, but both sexes undergo periodic weight fluctuations. It is not uncommon for the average ferret to add 30-40% of its body weight in fat deposited beneath the skin in the fall, and lose this fat the following spring. The average lifespan of ferrets is 9-10 years.
