The cheetah (Acinonyx jubatus) is a large-sized feline inhabiting most of Africa. The cheetah achieves by far the fastest land speed of any living animal in short bursts covering distances up to 1,600 ft and has the ability to accelerate from 0 to over 62 mph in three seconds. This cat is also notable for modifications in the species' paws. It is one of the only felids with semi-retractable claws, and with pads that, by their scope, disallow gripping. Thus, cheetahs cannot climb upright trees, although they are generally capable of reaching easily accessible branches by leaping.
