* Females: Female cheetahs live in groups called coalitions which are usually made up of sisters or mothers and daughters. These coalitions can have 2-6 individuals and work together to raise their young, hunt, and defend their territory.
* Males: Adult male cheetahs are often solitary or live in coalitions of 2-3 individuals.
* Young: Cheetah cubs stay with their mothers for about 2 years.
So, the "normal" group size for cheetahs depends on whether you're talking about females, males, or cubs.
