Wererat
A wererat is a therianthropic creature in the shape of a rat. The term is a neologism coined in analogy to werewolf, used in the fantasy or horror genre since the 1970s. The concept has since become common in role playing games and fantasy fiction inspired by them. Were-rats are commonly portrayed as sewer-dwelling scavengers and opportunistic thieves. Brad Steiger has written about wererat sightings in Oregon, mostly by children.
