It ranges from southwestern Minnesota and southeastern North Dakota to northern Texas east of the Rockies, and from northern Utah and Colorado to northern Chihuahua west of the Rockies.It has soft silky fur and grows to be 5 inches (13 cm) long, although nearly half of that is the tail.They often live directly underneath Spanish bayonet or prickly pear plants. They are accustomed to sandy soil and eat mostly seeds, large and small grasses and small leaves of plants. Some food found in their cheek pouches are: seeds of needle grass (Stipa), bind weed, sandbur grass, a small bean (probably Astragalus), and sedge (Cyperus).
