Generally, they are found in the dense forests only. They do not eat anything else except the eucalyptus plants. Somehow, they are also eaten by owls or eagles because they are not having a fighting nature. While they are known for eating the eucalyptus plants, they generally do not eat anything else but if they found anything of their like say, tea leaves, paper bark tree, they eat that also. As per the estimation, one Koala bear can eat up to 200-500 grams of eaves on daily basis. As these things are available near to mountains or in dense forests, they stay in those areas only. However, they also have to protect them from the attacks from other animals. The reason why Koalas eat a lot of eucalyptus leaves is that they are hard to digest because of which they can stay without eating anything for 2 days. Koalas sleep a lot because of which it also helps them in digestion. For sleeping at least 20 hours a day, they require bamboo stick which provide them better grip in maintaining balance and sleeping for long.
One of the most different and funny fact about the Koalas Bear is that they eat eucalyptus plants or any of their preferred food item only at night. Through the leaves, they also get water which supports them when they do not find anything to eat.
