Foxes are clever, and humanity generally respects cleverness. But they also have qualities that earn the ire of many people. They're natural predators to animals like rabbits and mice, which are often associated with innocence and sweetness. They're a menace to poultry farmers, often killing chickens, turkeys and waterfowl. They're an invasive species in certain places that are devastating to wildlife. They're notoriously associated with rabiesnote . And the un-dog-like sounds many species make are the stuff of nightmares.
So it's perhaps unsurprising that foxes are often depicted in a negative light, especially in children's media.
In fiction, it's not uncommon for foxes to be portrayed as sneaky, conniving, and unsavory. Antagonistic foxes will generally be evil geniuses or manipulative bastards. Even foxes who aren't predators get hit with this trope, especially if they are dangerous scavengers. Sometimes, they're mean-spirited tricksters who feign being good-natured. Sometimes, they're treacherous backstabbers who would sell virtually anyone up the river for a chance to get ahead, and other times they're just plain vicious bullies. Occasionally, they'll get portrayed as evilly seductive, sometimes complete with "foxy" wordplay.
