Koalas tend to be solitary creatures. They come together to mate in spring and early summer. At mating time the males are noisy and quarrelsome. Baby koalas are born approximately 35 days after conception. Although furless and weighing only half of a gram, the baby koala climbs into the mother's pouch unaided. Six months later it leaves the pouch. By now the baby koala is fully furred and the mother carries it on her back or cuddles it to her chest for another six months. Normally koalas have single babies and twins are rare. Koalas become mature completely after four years although the female is sexually mature at about two years.
