May. The gestation is varying from 90 - 110 days. Most of the births take place at night.
Labour takes about half an hour.
The interval between infants usually is 10 minutes. The afterbirth is eaten by the female. Babies are nursed nearly continuously by their mother during the first 2 weeks. They do not cling to their mother but stay the first days in the nest. The eyes of the infants are open at birth and they are covered with fur.
