There are 38 species of cats lives on Earth. Most of them are comparatively small.
The term “big cat” is are commonly used to relate to any of the five species of the genus Panthera: lion (Panthera leo), tiger (Panthera tigris), jaguar (Panthera onca), leopard (Panthera pardus), and snow leopard (Panthera uncia). Except for the snow leopard, these big cat species can roar. A more broad interpretation of the term covers species outside of Panthera including the cougar (Puma concolor), clouded leopard (Neofelis nebulosa), Sunda clouded leopard (Neofelis diardi), cheetah (Acinonyx jubatus) and even the several lynxes species. However, these added species also do not roar.
Notwithstanding tremendous diversity in size, various cat species are pretty alike in both body structure and behaviour, except the cheetah, which significantly stands out from the other big and small cats. All cats are carnivores.
