During the breeding season a den is dug. In this den up to 22 pairs may keep their young. Females will give birth in the open before quickly moving these young to the den. Pairs take turns at caring for the young in the den.

The first three weeks of the babies life is spent in or near the den. By 13 weeks the babies are weaned.
