SRD:Cheetah

=CHEETAH=

Cheetahs are swift feline predators of the plains. A cheetah is 3 to 5 feet long and weighs 110 to 130 pounds.

Combat
Cheetahs make sudden sprints to bring down prey.

Trip (Ex): A cheetah that hits with a claw or bite attack can attempt to trip the opponent (+3 check modifier) 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 per hour, a cheetah can move ten times its normal speed (500 feet) when it makes a charge.
