Conservation Status: Least Concern.

The Chisel-toothed Kangaroo Rat has chisel-shaped lower incisors, with which it strips the epidermis from the leaves of desert shadscale or saltbush, thereby reaching the palatable and water-rich interior of the leaf. This Kangaroo Rat eats more leaves than seeds, which is unusual for the genus. Its ability to subsist on perennial shrubs gives it an advantage when the climate does not support the growth of herbaceous vegetation. The species is common across the Great Basin of the western United States, and is also known as the Great Basin Kangaroo Rat.
