In captivity the breeding season starts during September to October, marked by increasing displays of aggression between members of the same sex (Stephenson et al., 1994). Most births in captivity occur from November to January and in the eastern humid forest generally from late November to early December, coinciding with the early part of the rainy season, when food is plentiful. Information from field notes and observations in captivity suggest that one litter of two to three infants per year is the norm. Infants open their eyes at 28 days old (Stephenson et al., 1994).
