Feeding ecology and diet

These animals are entirely herbivorous. Their diet includes the leaves, stalks, flowers, and seeds of almost any desert plant, including grasses and acacia trees. Preferred plants include those in the families Cruciferae and Compositae. Gundis are not adept at gnawing and their incisors lack the hard orange enamel characteristic of most rodents.

Food is often scarce and gundis may forage over great distances, sometimes traveling 0.6 mi (1 km) in a morning. Regular foraging is essential because food is not stored and fat reserves are not accumulated in the body.

Most gundis do not drink but obtain all the water they need from plants; their kidneys have long tubules for absorbing water and under extreme conditions their urine can be concentrated, although this emergency response can only be sustained for a limited period.
