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

In areas where the European polecat is sympatric with the steppe polecat, the two species overlap greatly in choice of food, though the former tends to consume more household foods and birds, while the latter preys on mammals more frequently. There is at least one record of a beech marten killing a polecat. The European polecat may prey on the much smaller least weasel. In some parts of the British Isles, the abandoning of domestic ferrets has led to ferret-polecat crossbreeds living
