Barrow rats are scavengers by nature and prefer to feed on dead animals or rotting corpses, even going as far as to gnaw through a wooden coffin to eat the flesh of a newly dead and buried creature. Food that is not immediately devoured is ripped into smaller pieces that can be carried and is whisked back to the barrow rat's nest and stored for later consumption or fed to the newborn barrow rats.

Barrow rats are 15-inch long brownish-gray rats with long gray or brown, hairless tails. Their underbellies are lighter in color than their fur often appearing white in some rare species, but usually appearing light brown or slate. Some barrow rats have a dark brown or black stripe on their dorsal side that runs the length of their body.

Barrow rats are not as numerous or populous as their normal relatives and are generally only encountered near barrow mounds or graveyards. Most encounters are at night as the rats sleep in underground burrows during daylight hours. A typical barrow rat nest holds 10-40 of the creatures with an additional 10-40 noncombatant young. One or two males dominate the nest. Typically there are two or three females that dominate the colony, but remain subordinate to the dominate male(s). Young are born live and a female typically gives birth to 3d8 young. The typical gestation period for a barrow rat is 1 month and young reach maturity in 3 months. Young are born blind and hairless and are completely dependent on their mother for several days thereafter. Young open their eyes around 20 days and the mother weans her young after about one month. Young barrow rats gain the stone skin ability at 30 days after birth.
