It dens in tree cavities, and the location of its nests indicates considerable arboreal ability. Males may be highly aggressive toward one another.
Communication is by tactile, chemical, and a few auditory signals.
Mating probably begins in October, during the austral spring, shortly after the adults emerge from torpor, and births take place in December or January. Females appear to be polyestrous and to exhibit several cycles of 6 days each during the mating season. Gestation evidently lasts 42-49 days. The young weigh about 8 grams at birth, open their eyes by their 9th day, and are functionally independent at 30-35 days. The Johns Hopkins University Press.
