Trip (Ex): A cheetah that hits with a claw or bite attack can attempt to trip the opponent as a free action without making a touch attack or provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the cheetah.

Sprint (Ex): Once an hour, a cheetah can take a charge action to move ten times its normal speed (500 feet).

Cheetahs make sudden sprints to bring down prey.
