Following nineteenth-century declines, polecats Mustela putorius are recolonising Great Britain. Polecat diet relates to two potential risks to recovery. First, rabbits Oryctolagus cuniculus, which are important prey for polecats, have experienced extreme population fluctuations, with near extirpation due to myxomatosis in the s, recovery in s—s and declines in s—s. Second, polecats are secondarily exposed to anticoagulant rodenticides by eating contaminated rodents, and the frequency of polecat exposure to rodenticides is increasing. We analysed stomach contents from 99 polecats collected in — and compared results with earlier studies. Diet varied seasonally; lagomorph occurrence was highest in spring and summer and lowest in autumn. Dietary niche breadth was greater in the s, when rabbits were scarce, than in other decades, but did not differ between the s and s, indicating that diets have not diversified with recent rabbit declines.
Polecats are rare in the British Isles, due to human pressure, but seem to be increasing in numbers in recent years. Polecats prefer to live along bodies of fresh water, in wetlands, on the edge of forests, or in grasslands with islands of scrub trees. Polecats display extreme sexual dimorphism, wherein males can weigh up to twice as much as females and be a third or more longer. They have a coat of creamy-colored underfur with black guardhairs. In winter, this coat is thick, smooth and glossy. In summer, after biannual shedding, the coat is thin and faded and loses the luster of the winter coat. Polecats have a raccoon-like dark mask around their eyes, surrounded by a white face accented with white-tipped ears. Like all mustelids, polecats have a pair of anal glands that emit a strong-smelling secretion.

During the winter, their diets overlap more with those of polecats, and will eat a larger proportion of rodents than in the summer, though they still rely heavily on frogs and rarely scavenge ungulate carcasses as polecats do.
