The mound mouse is a small rodent from the mouse family. It lives in steppes and builds mounds from soil and plants for housing and seed storage.
The mound mouse differs from other mice by building large earthen mounds for nests and supplies. It is important for nature as food for predators and as a seed disperser of plants in the steppe.
