Common house mice are small, slender rodents with large ears, sensitive noses, and small eyes. Their fur is typically dusty brown or dull gray on top, with lighter shades along the chin and stomach. The rodents have hairless tails that are long and scaly, and their feet are well-equipped for grasping, burrowing, and climbing. What they lack in eyesight they make up for with their other senses and continually explore their environments in order to memorize the locations of food sources, hazards, safe hideaways, and escape routes.
