August 5, 2012 — Take a look at this record-breaking kitty!
Sarah is the Cincinnati Zoo's 11 year-old cheetah, and now, she's the world's fastest land mammal.
She ran 100 metres in 5.9 seconds, beating her 2009 record.
It takes Usain Bolt - the world's fastest human - 9.8 seconds to clear that distance.
Zoo officials say Sarah was clocked sprinting at a staggering 98 kilometres per hour.
