European polecat European polecat The European polecat ("Mustela putorius") – also known as the common ferret, black or forest polecat, or fitch (as well as some other names) – is a species of mustelid native to western Eurasia and north Morocco. 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
European polecat deter intrusion. During the summer period, the diets of wild polecat-mink hybrids are more similar to those of minks than to the polecats, as they feed predominantly on frogs. During the winter, their diets overlap more with those of polecats, and will eat a larger proportion of rodents than in the summer, though they still rely heavily on frogs and rarely scavenge ungulate carcasses as polecats do. The European polecat can also hybridise with the Asian steppe polecat or the North American black-footed ferret to produce fertile offspring. European-steppe polecat hybrids are very rare, despite their sympatry in several areas.
