The cheetah is the only cat species that lacks fully retractable claws. Its claws provide extra traction when running, but they do not stay sharp like those of other cats.
Cheetahs are built for speed, with flexible spines that allow them to take huge strides and long tails that help them balance while making sharp turns. From a standing start, cheetahs can reach speeds of up to 60 miles per hour in just three seconds and have been clocked at up to 70 miles per hour. Cheetahs' speed allows them to prey on fast, agile animals such as gazelles, impalas and hares.
