Tigers are wild animals. They live in many places in the world, from China to American. Tigers are big animals. Their legs are very strong, so they can run very fast. Some tigers live in the mountains. They usually live for about 15 years and eat small animals like young zebras, monkeys and rabbits. They sleep for about twelve hours a day. When they are not sleeping, they often hide behind the trees to catch small animals. When a small animal pass, a tiger jumps on the animal and catches it. Then he eats it slowly.
