Koalas have several natural enemies in their lives, one of which is the Australian dog. When koalas slowly walk from tree to tree, both adult koalas and young koalas may be hurt by Australian dogs. Koalas are sometimes attacked by eagles and owls; Others like wild cats, dogs and foxes are also natural enemies of koalas. Koalas sleep 20 hours a day, and in the other four hours, they eat leaves for 2 hours and stay in a daze for 2 hours. Most koalas fall to death, because when they get old, they will fall to death because they can't catch trees. Affected by human roads and traffic, koala habitats are decreasing, and habitat destruction is the biggest threat to koala survival. If koalas live in remote areas or near major roads, they are likely to encounter car accidents and dog attacks. The Australian Koala Foundation estimates that at least 4,000 koalas die in car accidents and are attacked by dogs every year.
