Ecology
Habitat
Habitat and Ecology
It is nocturnal, solitary, and terrestrial. The diet includes seeds (of Acacia, Ficus, Convolvulus, Liepenus, Prosopis, and Alicarpus), green plant material, and arthropods (spiders, beetles, crickets, and moths). Seeds about the size of garden peas are preferred. The relative proportion of vegetable and animal foods in the diet varies widely among different populations, which suggests opportunistic feeding (Alvarez et al. 1984, in Reid 1997). Breeding occurs almost year-round, except early in the dry season (Reid 1997)

Life History and Behavior
Reproduction
Reproduction
No clear seasonality to breeding and pregnancy, though males were found with larger testes from March to April compared to November to February. Two to six young are born after a gestation period of approximately 25 days. Females flee the nest if startled and return later to move young by carrying them in their cheek pouches. Litters usually break up after 1-2 months.
