The Dzungarian hamster breeds from February to November. It is known to breed only once or occasionally twice a year in the wild, but it can breed more than that in captivity. In the wild, males and females meet only to copulate, then separate permanently. The gestation period is typically 20-22 days, but can be as short as 18-19 days. Litter size is usually between 5 and 12. The young are born blind and hairless, weighing approximately 1.4 grams. They are cared for by the mother alone, and they are weaned after a month or so. The young become sexually mature soon after weaning, or at a couple of months age, which helps to give this species an impressive capacity for reproduction. (Macdonald 1984, Nowak 1991, Parker 1990)
