Watch a cheetah jump into vehicle during a safari

"A cheetah decided to explore our vehicle on a safari I was leading for Grand Ruaha Safaris (in the Serengeti National Park," wrote wildlife photographer Peter Heistein on Instagram. "Another one jumped up on the hood and was staring at us through the windshield. They were just curious, we kept calm and let them go about their business. Quite a thrill to be this close!

"Our guide Alex Mnyangabe... helped us through the encounter with instructions on how to treat the animal 'with respect.'"
