In Old French, the polecat was called , which was derived from the Low German and Scandinavian verb for "to make a disagreeable smell".

Local and indigenous names


Dialectal English names


Latin name

As well as the several indigenous names referring to smell (see above), the scientific name ''Mustela putorius'' is also derived from this species' foul smell. The Latin ''putorius'' translates to "stench" or "stink" and is the origin of the English word ''putrid''.

, the European polecat likely was first domesticated in these regions. The ferret and European polecat are similar in both size and portions, to the point that dark-coloured ferrets are almost indistinguishable from their wild cousins, though the ferret's skull has a smaller cranial volume, and has a narrower postorbital constriction. Compared to the European polecat, the ferret has a much smaller brain, though this comparison has not been made with Mediterranean polecats, from which ferrets likely derive. The theory of a Mediterranean origin is further strengthened because the ferret is less tolerant of cold than northern polecat subspecies. Unlike other subspecies, which are largely solitary, the ferret will readily live in social groups. The ferret is also slower in all its movements than the polecat, and hardly ever makes any use of its anal scent glands. Overall, the ferret represents a

The feet are moderately long and more robust than in other members of the genus.

Fur

The winter fur of the European polecat is brownish black or blackish brown, the intensity of which is determined by the colour of the long guard hairs. On the back and flanks, the dark tone is brightened by bright whitish-yellowish, sometimes yellowish-greyish underfur which shows through. The lightly coloured underfur is not equally visible on different parts of the body. On the back and hindquarters, the underfur is almost completely covered by the dark guard hairs. On the flanks, though, the lightening is well defined, and contrasts sharply with the general tone of the back. The throat, lower neck, chest and abdomen are black or blackish brown. The limbs are pure black or black with brown tints, while the tail is black or blackish brown, completely lacking light underfur. The area around and between the eyes is black-brown, with a longitudinal stripe of similar colour along the top of the nose. The ears are dark brown and edged with white. The summer fur is short, sparse and coarse. It is greyer, duller and lacking in the lustre of the winter fur. The underfur is more weakly developed in the summer fur, and has a brownish-grey or rusty-grey colour. The polecat is a good swimmer, but its fur is not as well insulated against cold water as the

, leucists, isabellinists, xanthochromists, amelanists, and erythrists. In typical erythristic individuals, the underfur is usually bright reddish. The guard hairs on the trunk are bright reddish or reddish brown. Black guard hairs are absent on the lower body and head. In some rare cases, the guard hairs are so light, they are almost indistinguishable from the pale-yellow underfur. These individuals are called "amelanistic". In these cases, the whole animal is a very light golden-yellow colour. These individuals are called "isabelline" or "xanthochromistic".


Behaviour


Social and territorial behaviours

Unlike the steppe polecat, the European polecat has a much more settled way of life, with definite home ranges. The characteristics of polecat home ranges vary according to season, habitat, sex and social status. Breeding females settle in discrete areas, whereas breeding males and dispersing juveniles have more fluid ranges, being more mobile. Males typically have larger territories than females. Each polecat uses several den sites distributed throughout its territory. Occasionally, abandoned

burrows are used. Rabbit warrens are often areas of intense polecat activity. In winter, the polecat may use farm buildings or haystacks as daytime resting sites. The polecat is not as territorial as other small mustelids, having been known to share territories with other members of the same sex. Evidence of polecats marking their territories is sparse. Like other mustelids, the polecat is usually a silent animal, though it will growl fiercely when angered, and squeak when distressed. It also emits a low, mewling cry to its mate or offspring.


Reproduction and development

The European polecat is a seasonal breeder, with no courtship rituals. During the

lasts 40–43 days, with litters usually being born in May-early June. Each litter typically consists of five to 10 kits. At birth, the kits weigh 9-10 g and measure 55–70 mm in body length; they are blind and deaf. At the age of one week, the kits are covered in silky, white fur, which is replaced with a cinnamon brown-greyish woolly coat at the age of 3–4 wk.
