Compared to a similarly-sized leopard, the cheetah is generally shorter-bodied, but is longer tailed and taller (it averages about 90 cm (35 in) tall) and so it appears more streamlined. An cheetah weighs about 95-250 pounds.
Average life span in the wild: 10 to 12 years. Size: 3.5 to 4.5 ft (1.1 to 1.4 m); Tail, 25.5 to 31.5 in (65 to 80 cm). Weight: 77 to 143 lbs (35 to 65 kg). Protection status: Vulnerable. Size relative to a 6-ft (2-m) man: The cheetah is the world's fastest land mammal.With acceleration that would leave most automobiles in the dust, a cheetah can go from 0 to 60 miles (96 kilometers) an hour in only three seconds.ize relative to a 6-ft (2-m) man: The cheetah is the world's fastest land mammal.
