Koalas live an average of 20 years in the wild. Although owls or dingos sometimes prey upon koalas, dogs and motor vehicles are responsible for the majority of koala deaths in the wild.
Koalas live in the eucalyptus forests of eastern and southeastern Australia where the trees provide them with food, safety and shelter. They spend most of their lives in the trees, sleeping about 18 hours a day and eating eucalyptus leaves most of their waking hours. Koalas eat about 2 1/2 pounds of eucalyptus leaves per day and even store some of the leaves in pouches in their cheeks for later consumption.
