Cheetahs (Acinonyx jubatus) is the most primitive of all big cats. The don’t act like the rest of the cats.  While most of the big cats are ambush predators (waiting for prey to come close and surprising it), cheetahs chase their prey.  They are famous for their speed (which are estimated to be as fast as 128km/h), but can only keep that speed for short amounts of time.  They stalk close to their prey, and then rush it.  Their feet help them run, since they have semi-retractable claws.  Most cats have fully retractable claws, able to tuck them away into the pads of their feet so they can move silently.  Cheetah claws are always out.  This helps them gain traction as they’re chasing down their prey.
