Sugar gliders, like kangaroos, have a pouch. About 16 days after mating, the small embryos pass through the vagina and crawl to the pouch. There they nurse off of their mother's milk and develop for another 60-70 days. After that time, the mother sugar glider will leave them in the nest while she forages for food. At 4 months of age, the young sugar gliders are on their own.
Sugar gliders are extremely social, especially for marsupials.
They live in small family groups with up to seven adults and their young in a nest. This also helps to conserve heat when the weather is cold. They have scent glands which they use to mark their territory, and also mark their nest with urine. They communicate using a wide variety of vocal sounds. In the wild, sugar gliders live about 4-5 years.
