The European polecat (Mustela putorius) — also known as the black or forest polecat, or fitch (as well as some other names) — is a species of mustelid native to western Eurasia and North Africa. 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 — also fellow members of the genus Mustela — the polecat has a shorter, more compact body a more powerfully built skull and dentition, and is less agile.
