Cats are unhealthy felines found within Meiyerditch. They seem to have human owners, as they wear collars. Unlike the stray dogs wandering the area, the cats have a talk-to option. If talked to without a catspeak amulet (e), or a cramulet, they will simply exclaim Miaoww in the overworld chat. However, when talked to with any of the above amulets, players can learn that they are trapped within Meiyerditch, and are rarely fed (as the humans themselves have little food), but are siding with the humans and wish to help them escape.
After River of Blood, the cats learn of the new alliance and are content with the progress being made, stating that their situation went from "really bad" to plain bad.
