Do they live in groups? Male cheetahs will often group together in groups called coalitions. They usually group with brothers, but may also group with an existing group or other males that were the lone male in their litter. Female cheetahs, however, hunt alone with the exception of their own cubs.
Researchers have learned that, during mating season, cheetah males make a unique sound called a âstutter-bark,â which is a very rhythmic and repetitive call that sounds like a cross between a purr and a rumbling stomach. The stutter-bark seems to play a role in getting an available female âin the moodâ for breeding.
