Kangaroos are herbivores, eating all kinds of plants, and some also eat fungi. Most of them are active at night, but some of them are active in the early morning or evening. Kangaroos feed on short, moist grass close to the ground, leaving long grass and hay to other animals.

Individual species of kangaroos also eat leaves or small tree teeth. The "racial discrimination" of kangaroo family is very serious. They can't tolerate foreign members entering the family, and even don't welcome family members who have been away for a long time. Even if the family accepts a new member, it must be taught a lesson. After new members learn many "rules", they can be integrated with their families.

Extended data:

Kangaroos usually live in groups, sometimes as many as hundreds. But some smaller kangaroos live alone. In the wild, when kangaroos are chased by the enemy, they have their own unique counterattack methods.

With their backs to the trees, they hit the ground with their tails and kicked the running enemy's abdomen with their powerful hind legs. However, kangaroos are relatively docile and honest animals in zoos. They are carefully taken care of, eat nutritious feed and get used to life in the zoo. In cold weather, I moved into a greenhouse with big glass windows to live.
