The Cincinnati Zoo says one of its cheetahs has become the fastest land mammal on record - twice.
Zoo officials say an 8-year-old female named Sarah ran 100 meters in just over 6 seconds Wednesday. That breaks the old record set in 2001 by a cheetah in South Africa by a few hundredths of a second.
Later, Sarah ran a slightly faster time. The speed translates to more than 36 miles per hour.
The cat was clocked at a breeding center on a certified course. Cheetah records are maintained by conservation groups and zoos.
The human 100-meters record holder is Usain Bolt of Jamaica. He's a relative slowpoke at over 9 seconds.
