what just cheetahs eat ? Are they related to tigers ?
http://en.wikipedia.org/wiki/Cheetah
Cheetahs primarily eat meat and are carnivores. They mainly prey on small to medium-sized ungulates such as gazelles and impalas. However, they are opportunistic hunters and will also feed on smaller mammals like hares and birds if the opportunity arises.
As for their relation to tigers, cheetahs and tigers are both large cats, but they belong to different species and genera. Cheetahs belong to the Felidae family, while tigers belong to the Panthera genus. This means that they are not closely related. Tigers are larger and have different physical and behavioral characteristics compared to cheetahs.
