The adults are still just called "cheetahs." It is common for people to put the word "ess" at the end of female cats' names, however. EXAMPLE: Tigress, Lioness, Leopardess, cheetess. Babies are called "cubs", or occasionaly, "kittens".
They are usually just called "cheetahs", but the rule of putting "ess" at the end of a female cat's name can apply here, so a female cheetah could be called a "cheetess".
There is no specific term.Following the form of lion (lioness), tiger (tigress), and leopard (leopardess), it would seem there would be a recognized name such as cheetess, but none has ever stuck. The same applies to the female ocelot, and female domestic cats are seldom called anything but cats or she-cats.There is no name for them, they are simply called "Female cheetah".
