mouse, name applied to numerous species of small rodents, often having soft gray or brown fur, long hairless tails, and large ears. The chief distinction between these animals and the variety of rodents called rats is in size: mice are usually smaller. Many small rodents are adapted for leaping or hopping and are named accordingly, e.g., the North American kangaroo rat and Asian jumping mouse.
