Cheetah's make numerous other noises, such as chirping, churring, growling, and purring. A mother cheetah chirps when she's trying to locate her cubs. Churrs are emitted during social meetings. You'll often hear a cheetah growl when they are annoyed or face danger. And just like a kitty, a cheetah will purr when it's content.
