Gestation lasts for about two months, and results in the birth of a litter of up to six young, with three being typical. The young are initially blind and weigh . They open their eyes at seven days, begin to take solid food at twelve days, and are fully weaned by the end of their first month. Litter mates frequently spar with one another, and disperse to establish their own burrow systems after around two months, by which time they have already reached nearly half the adult body weight. They live for over six years.
