Litters generally contain 2 young, but sometimes may have 1 or 3. Babies are born outside of the burrows, but move inside shortly afterward. They are well developed at birth, their eyes are open and they can move about freely. They are weaned by the age of 11 weeks, and females are capable of producing litters as early as 8 months. Three or four wild individuals are often seen traveling together in single file, but occasionally groups up to 40 individuals can be observed.
Groups disperse at night and congregate in feeding areas by day.
There is no territoriality and the entire colony shares space. Males have a dominance hierarchy which is maintained by aggression. The basic social unit is the mated pair, and strict monogamy is practiced. The female initiates most movements, and the male follows closely behind to defend her against other males. Their diet consists of any available vegetation.
