Ring-tailed lemurs are very gregarious animals, and it is interesting to note that in a group of lemurs the males must be in the majority to ensure a healthy social and reproductive environment. However, the troop is headed by one or more females, making it a matriarchal society. Adult females are 100% dominant over males. Males are inhibited from attacking females, whereas females supplant, cuff, or chase males with impunity. A viable troop consists of 3 to 4 males, 1 or 2 females, and the young. When a ring-tailed lemur eats juicy food it bites off pieces with the molars, so that the juice runs directly into the mouth and does not wet the fur. They are fastidiously clean and groom constantly, using grooming digits on the hind feet. These animals possess a hairless glandular region on the inside of each lower arm above the wrist. Males have an additional gland on the upper arm which secretes a strong-smelling fluid. Every foreign object in the lemur’s territory or cage is marked with this glandular secretion. Ring-tails jump quite effortlessly, even vertically up 10-foot walls. During sleep they curl up, burying their heads and arms between their legs, and wrapping the long tail around the body vertically. They can make soft purring sounds or piercing screams.
