Reproductive biology

The breeding season is in spring, and males and females mate in October soon after emerging from hibernation. The first litters appear in November, but continue to be born until January. Litters of between one and four young are normal; there are some records of five but, since the female only has four teats, the chances are the fifth will not survive. The young spend the first few weeks of life in their mother's pouch, attached to a teat. As soon as they are old enough to maintain their own body heat, the female leaves them in the nest while she goes out to feed. A little later, the young family accompanies the mother, at first riding on her back, and then learning to climb and feed themselves. Once independent, they often remain close to their mother for the rest of the year. They are sexually mature at one year old.
