A cheetah can run at almost 70mph for short distances (0 to 45mph in two seconds). It's body resembles a greyhound's and it's the only cat unable to retract its claws. The King Cheetah, with its black stripes down it's back and splotches instead of spots, was originally thought to be a completely new species, but it is actually the result of a mutation inherited as a single autosomal recessive allele. The majority of the world population of king cheetahs (about less than 50) are descendants of zoo-bred cats. There are probably less than ten free-living kings.
