The koala has thick fur that is used to help keep it cool and at the same time warm. Their fur also acts like a rain slicker, repelling moisture. The color of their fur changes from gray to brown depending on the season. They have patches of white on their neck, chest, and inside the ears, legs, and arms.The koala usually mates during September-March. The female koalas start to mate with the male koalas when they're around 3 or 4 years old! They sometimes only produce one offspring per year.
