The eyes and ears of a cheetah say much about its mood. If the ears are half back and the eyes half closed, they are aware, mildy disapproving, but not alarmed. But if their ears move forward and the eyes open wide, they are alert and ready for action. The greater the danger, the wider the eyes and the flatter the ears.
Nothing is more exciting than to watch a cheetah hunting. Within a few paces, it will reach a speed of 40 miles per hour and can cover a hundred yards in three seconds.
