Mice are more brown to begin with, and have darker bellies. Next is the tail. It's black with scaley rings on a rat, and tan and more smooth on a mouse. The feet of a rat are also longer in proportion to the body, and a rat's ears are also larger. But these variations are subtle. The primary thing, of course, is the size difference.
