<P> The informal term "big cat" is typically used to refer to any of the five living members of the genus Panthera, namely tiger, lion, jaguar, leopard and snow leopard . Except the snow leopard, these species are able to roar . A more liberal and expansive definition of the term includes the puma, clouded leopard, Sunda clouded leopard and cheetah, although these added species do not roar . </P> <P> Despite enormous differences in size, various cat species are quite similar in both structure and behaviour, with the exception of the cheetah, which significantly stands out from the other big and small cats . All cats are carnivores and efficient apex predators . Their range includes the Americas, Africa, and Asia . </P>
