A single mole rat has been estimated to be able to excavate up to 500 kilograms (1,100 lb) of soil in a month, under ideal conditions. [6] Such burrows consist of numerous tunnels that the mole rat uses to search for food, and a few, deeper chambers used for nesting, food storage, and as latrines.
Naked mole-rats feed primarily on very large tubers (weighing as much as a thousand times the body weight of a typical mole-rat) that they find deep underground through their mining operations. A single tuber can provide a colony with a long-term source of food—lasting for months, or even years, as they eat the inside but leave the outside ...
Marsh rice rats sometimes make large runways or dig burrows. [146] They are accomplished and willing swimmers, easily swimming more than 10 m (33 ft) under water, [147] and often seek safety in the water when alarmed. [148] Rice rats in the Florida Keys occasionally climb in vegetation, but never higher than 90 cm (3.0 ft). [149]
Additionally, burrows can protect animals that have just had their young, providing good conditions and safety for vulnerable newborn animals. [19] Burrows may also provide shelter to animals residing in areas frequently destroyed by fire, as animals deep underground in a burrow may be kept dry, safe and at a stable temperature. [21]
However, they are all bulky, slow-moving rodents that live and forage in extensive burrow systems and rarely spend much time above ground. They feed on the underground parts of plants. They live at altitudes of 1,200 to 4,000 m (3,900 to 13,100 ft) and, except for the lesser bamboo rat, feed principally on bamboo and live in dense bamboo thickets.
By the 1750s, brown rats were in New York City, destined to be subway kings. Ironically, for how widespread it is, the brown rat is a homebody. "In its natural habitat, it has a very small home ...

Ord's kangaroo rats are nocturnal, and spend their days in deep burrows. [26] Males are usually more abundant and active than females. Activity increases under cloud cover, particularly in winter. [7] Ord's kangaroo rats are active year-round in Texas, but further north, they are seldom seen above ground in cold weather. [26]
