Pet ferrets could be labeled "sweet creatures". Pet rats could be labeled "sweet creatures". Outside captivity, polecats(wild ferrets) are not nice. Outside captivity, rats are not nice. The distinction may lie in that, while otters and badgers rarely eat other mammals, a polecat's diet is made up almost entirely of meat. Rats eat other mammals on a regular basis, including mice, rabbits and even small chickens. Rats also scavenge for garbage and carrion, which puts them in the category to which crows also belong(note that crows are also portrayed as evil). Foxes, wildcats, vipers, monitor lizards, and wolverines also appear almost exclusively as villains, and every one of these species will eat mice, voles, squirrels, chickens, rabbits, and many other small animals. River otters eat crustaceans, fish, and other seafood. Hares are mainly herbivores, as are rabbits. Squirrels are primarily herbivores, but will eat small insects. Mice eat various grains and seeds in the wild. That is why, I believe, ferrets are considered evil; while badgers, otters, mice, squirrels, and other "goodbeasts" are not.
