Gray mouse lemurs are nocturnal, solitary foragers who congregate at daytime sleeping sites. Females and dependent offspring will sleep in groups of up to 15. Home ranges of females are grouped into core areas and one male's home range can overlap those of several females. Females are considered to be dominant over males, giving them preferential access to food and the choice of with whom to mate. (Female dominance in primates is unique to prosimians.)
