Stimpson "Stimpy" J. Cat is just what he sounds like. A cat. A roly-poly, no-brains cat, duhhhhh. And if not for the psychotic ways of his best friend Ren, Stimpy would lay around on his belly, smiling and belching up fish bits all day long. But think of all the fun he would miss! Lucky for Stimpy, he doesn't have a big enough brain to care.
