That is a polecat ferret.Kay where was this population of wild polecats (just county will be close enough).
Para it was Shropshire /Staffordshire border , the animal was clipped by a car as i recall & treated at a vet somewhere i just expected a ferret to be dropped off , this wasnt a ferret , that became obvious after it had been here a few days & bit me like no other bite i have had in my life , once i secured it it was fairly easy to look after , wouldnt touch anything other that fur & feather , wouldnt drink from a bottle & it screamed & backed up a corner in the
