Reproductive biology

Little is known about reproduction in Abrocoma. Gestation times have been documented for A. cinerea, ranging from 115 to 118 days, with litters of one to two young. Litters of up to six have been described, and indeed may be more the norm, as shown by field work that collected pregnant females in Chile with embryo counts of four, five, and six.

Pregnant A. cinerea females, or females with newborns, have been collected during the months of April, the end of July and August, and at the beginning of June. Mating would have occurred in the early months of the year. Details of mating are unknown.
