The house mouse is a small murid with a slender body, a nearly hairless, scaly tail and fur ranging from light brown to black. Its underside is generally white or buff. Head-and-body length is 6.5–9.5cm, while the tail can be almost as long as or longer than the body. Wild individuals weigh 12–30g, and males and females are similar in outward appearance.

House mice live closely alongside people in houses, barns and grain stores, but also occupy fields, fencerows and wooded places near buildings. They are generally nocturnal and are capable runners, climbers, jumpers and swimmers. Their flexible diet includes stored foods, seeds and other plant matter, insects and carrion. Females can breed repeatedly when conditions permit, bearing 3–12 young after a gestation of 19–21 days. (Animal Diversity Web)
