Cheetahs have black tear lines on their face and are the fastest land animal, able to run up to 115 km/hr. They hunt alone instead of in packs like leopards. About 90% of cheetah cubs die in their first few weeks due to being hunted by other animals like lions and leopards. While cheetahs and leopards are both big cats, they differ in that cheetahs have black tear lines and no facial spots, are smaller, rely on speed over ambush attacks, purr differently, and cheetahs cannot roar like leopards.
