    Reproduction: Elaborate mating nests, 150-250 mm long by 150-150 mm wide, are built out of shredded grass or leaves and placed in tunnels or under logs and rocks. The breeding season extends from early spring to early fall (March-September), although some scattered reproductive activity may occur throughout the entire year. Females may have up to 3 litters per year, although 2 is more usual. Gestation is 21-22 days and litter size is 3-10, although 5-7 pups is most common. The young leave the nest when 18-20 days old and are weaned several days later. Females reach sexual maturity at 6 weeks, while males mature at 12 weeks. The life span can be as long as 3 years, but it is usually much more brief.
