en.wikipedia.org/wiki/Big_cat
The term big cat, while not a biological classification, is used informally to distinguish the larger felid species from smaller ones. One definition of "big cat" includes four members of the genus Panthera: the tiger, lion, jaguar and leopard. Members of this genus are the only cats able to roar. A more expansive definition of "big cat" also includes the cougar, cheetah and snow leopard.
Despite enormous differences in size, the various species of cat are quite similar in both structure and behavior, with the exception of the cheetah, which is significantly different from any of the big or small cats. All cats are carnivores and efficient apex predators. Their range includes the Americas, Africa, Asia and Europe.
