The Polecat (Mustela putorius) is a member of the weasel family (Mustelids) and is also known as a 'Fitch'. It is related to stoats, otters, weasels and minks.
Polecats were once widespread and common throughout mainland Britain. However, due to heavy persecution by gamekeepers up until the late 1930's, polecats where in decline everywhere except for a small population in north Wales.
Recovery of populations has resulted in them now being widespread throughout rural Wales, the Border counties and are spreading across the Midlands, South and into the South-East of England.
