1. Family ties
Polecats belong to the carnivore family mustelidae, which also includes otters, weasels, martens, mink, badgers and wolverines.
2. Name and shame
Polecats are known for their pungent odour. Indeed, their common name may derive from old European words for foul-smell.
3. Shakespearean tragedy
A line in The Merry Wives of Windsor suggests that the polecat’s reputation wasn’t so good in Shakespeare’s time: “Out of my door, you witch, you hag, you baggage, you polecat, you runyon!”
4. Going native
It’s unclear whether polecats are native to UK. They are one of only three British mammals not to have a Celtic-derived Welsh name, the other two being the fallow deer and rabbit – both introduced.
5. Fall and rise
Once widespread in Britain, polecats were hunted almost to extinction by gamekeepers in the 1900s. Since the 1950s, they have been recolonising England from a refuge in Wales. They have also been reintroduced to Scotland.
6. Wild thing
Polecats are the wild ancestors of domestic ferrets, which were bred for hunting rabbits. Ferrets generally have smaller brain cases than polecats, a less distinctive face ‘mask’ and more pale patches in their pelt.
7. Friend or foe?
A self-sustaining population of feral ferrets has established itself on Shetland. In New Zealand, where they were introduced to control rabbits (themselves introduced), feral ferrets are suspected of spreading TB to native and agricultural animals.
