this: the mammal

The ferret is a domestic mammal of the type Mustela putorius furo. Domestic ferrets typically have brown, black, white, or mixed fur, are predators, have an average length of approximately 20 inches (51 cm) including a 5 inch (13 cm) tail, weigh about 1.5-4 pounds (0.8-2 kg) (males are typically substantially larger than the females), and have a natural lifespan of 7 to 10 years.

Several other small, elongated carnivorous mammals belonging to the family Mustelidae (weasels) also have the word "ferret" in their common names, including an endangered species, the Black-footed Ferret. The ferret is a very close relative of the polecat, but it is as yet unclear whether it is a domesticated form of the European Polecat, the Steppe Polecat, or some hybrid of the two.

The history of the ferret's domestication is uncertain, like that of most other domestic animals. It is very likely that ferrets have been domesticated for at least 2,500 years, but it is not certain for what purpose the ferret was originally domesticated. They are still used for hunting rabbits in some parts of the world today, but increasingly they are being kept simply as pets.

Being so closely related to polecats, ferrets are quite easily able to hybridize with them, and this has occasionally resulted in feral colonies of ferret polecat hybrids that have been perceived to have caused damage to native fauna, perhaps most notably in New Zealand. As a result, some parts of the world have imposed restrictions on the keeping of ferrets.

History

Like most domestic animals, the original reason for ferrets' domestication by human beings is uncertain but it may have involved hunting. It was most likely domesticated from the European polecat (Mustela putorius), though it is also possible that ferrets are descendants of the Steppe polecat (Mustela eversmannii), or some hybridization thereof. Analysis of mitochondrial DNA suggests that ferrets were domesticated around 2,500 years ago, although what appear to be ferret remains have been dated to 1500 BC. It has been claimed that the ancient Egyptians were the first to domesticate ferrets, but as no mummified remains of a ferret have yet been found, or any hieroglyph of a ferret, and no polecat now occurs wild in the area, that idea seems unlikely.

The Greek word ictis occurs in a play written by Aristophanes, The Acharnians, in 425 BC. Whether this was actually a reference to ferrets, polecats, or the similar Egyptian Mongoose is uncertain.

The name "ferret" is derived from the Latin furittus, meaning "little thief", a likely reference to the common ferret penchant for secreting away small items. Ferrets were probably used by the Romans for hunting.
