　　Cheetahs are big cats. They are often seen in small groups on the grassy plains that are their home. As they are the fastest runners of all animals， they are able to hunt in the day time. They can achieve 100 kilometers per hour to catch their prey. However， they cannot keep this speed for long. The average chase lasts for less than half a minute. Cheetahs usually hunt small antelopes or the young of some larger species. A cheetah‘s claws are blunt. Its method of killing is to knock the prey off balance and then strangle it. They are messy eaters and often lick the blood off each other’s face after feeding. Cheetahs are now becoming very rare in many places.
