Polecats have recovered from near-extinction in Wales to recolonise much of England following persecution reductions. Their welfare depends on continued legal protection and connectivity of suitable habitats.
Polecat welfare is primarily affected by road mortality and incidental killing in traps set for other species. Road casualty surveys indicate that polecats are among the most frequently road-killed mustelids, reflecting their habit of foraging along linear features including verges. Gamekeeping traps set for rabbits or grey squirrels may kill polecats as non-target species; this is a welfare harm even if unintentional. The hybridisation with domestic ferrets creates uncertainty about the genetic integrity of recovered populations but does not create direct welfare issues for individual animals. Myxomatosis outbreaks affecting rabbit populations cause prey reduction that affects polecat condition and reproductive success; polecats compensate by switching prey but their specialisation for rabbit hunting means this is a welfare-relevant challenge. The recovery story is a conservation success that required only reduction of persecution rather than active intervention.
