Desert kangaroo rats are denizens of desert areas with sandy soil; vegetation is typically sparse and consists of creosote bush, a variety of grasses, and cacti. [8] Desert kangaroo rats live in burrow systems under slight mounds of soil 6-9m across; [8] they sleep in a den, which is sealed off at extreme temperatures, during the day. [4]
Rats are said to establish an order of hierarchy, so one rat will be dominant over another one. [52] Groups of rats tend to "play fight", which can involve any combination of jumping, chasing, tumbling, and "boxing". Play fighting involves rats going for each other's necks, while serious fighting involves strikes at the others' back ends. [53]
Kangaroo rats also live in colonies that range from six to several hundred dens. [10] The burrow of a kangaroo rat is important in providing protection from the harsh desert environment. To maintain a constant temperature and relative humidity in their burrows, kangaroo rats plug the entrances with soil during the day. [4]

At such times, home ranges may shrink to as little as 0.65 ha (1.6 acres). [10]
