This is about as close as you can get to a wild Cheetah family without getting mauled. At this distance they were growling and hissing much like a house cat does. However when communicating whit each other, Cheetahs chirp like birds. The Cheetah is the only species of cat that does not have retractable claws, and as most people know is the fastest land animal on the planet and can reach speeds greater than 70 mph. Cheetahs hunt in packs for antelope but are fearful of animals such as warthogs due to their razor sharp tusks.
