Cheetahs top out around 70 mph -- more than double the top speed of the fastest domestic cats -- during the course of 200- to 300-yard sprints. By way of comparison, lions run at about 50 mph, not quite double that of domestic cats. Think your house cat gets the zips? Cheetahs can go from zero to 60 mph in three seconds with strides that cover 23 to 25 feet apiece, according to National Geographic.
