That's probably because they're creepy little bastards who like scampering out of sight behind and under things and causing you to be all "goddamn what is that fuckface plotting behind there? No doubt it is something dastardly"

They also walk like fucking creeps, even moreso when you cripple them.

I'm working on an academic theory that they are not animals of this earth, but the remnants of ancient cosmic horrors who have evolved backwards in a last-ditch effort at survival. Also, they have psychic powers that cause nightmares in humans and let them astral-project into the minds of deliriant-abusing psychonauts.
