The European polecat ("Mustela putorius")  is a species of mustelid native to western Eurasia and north Morocco. It is also known as common ferret, black or forest polecat, foumart, or fitch. It is dark brown , with a pale underbelly and a dark mask across the face. Occasionally, there are other color variations, such as albinos. The family it is in also contains minks and other weasels. Compared to them, the polecat has a shorter, more compact body; a more powerfully built skull and teeth; and is less agile. It is well known for its ability to secrete a particularly foul-smelling liquid to mark its territory.
