Kangaroo mouse
The Dark Kangaroo Mouse is also known to feed occasionally on insects and carrion. Interestingly, the mouse never drinks water, instead deriving it metabolically from the foods it eats. The kangaroo mouse collects food and maintains large stocks in their burrows. The burrow, the entrance to which the mouse covers during daylight hours, is also used to raise litters of between 2 and 7 young. The Pale Kangaroo Mouse burrows only in fine sand, while the Dark Kangaroo Mouse prefers fine, gravelly soils but may also burrow in sand or sandy soil. Kangaroo mice are nocturnal, and are most active in the two hours following sunset. They are believed to hibernate during cold weather.
