Enjoyed only by the cheetah. This is a very simple proposition, Doctor. A leopard, through deleterious mutation, lost the ability to retract its claws. Those claws became blunt and dog-like. The individuals carrying the mutation, unable to climb trees, had to rely on their speed over the ground. The fastest survived -natural selection- and the cheetah was born.
According to the San Diego Zoo, Leopards have retractable claws. Cheetahs on the other hand only have partially retractable claws. This ensures that they maintain traction when they make turns at a full run.
