It is of a generally dark brown colour, with a pale underbelly and a dark mask across the face. Occasionally, colour mutations, including albinos and erythrists, occur. Compared to minks and other weasels – fellow members of the genus "Mustela" – the polecat has a shorter, more compact body; a more powerfully built skull and dentition; is less agile; and it

The skull is heavier and more massive than that of the European polecat, having more widely spaced zygomatic arches and more strongly developed projections, particularly the sagittal crest. It greatly resembles the black-footed ferret of North America, with the only noticeable differences between them being the steppe polecat's much longer and softer fur, shorter ears, and shorter postmolar extension of the palate. It has four pairs of teats and well-developed anal glands, which can produce a sharp-smelling liquid which is sprayed in self-defence. Males measure 320–562 mm in body length, while females measure 290–520 mm. Tail length
