Felinae
Pantherinae
Acinonychinae
Machairodontinae (extinct) All cats are members of the family Felidae. The felines are the most strictly carnivorous of the nine families in the order Carnivora. The cats' closest relatives are thought to be the other families in their branch of the carnivore evolutionary tree: the civets, hyenas, and mongooses. The first felids emerged during the Eocene, about 40 million years ago. The most familiar feline is the domestic cat, which first became associated with humans between 7000 and 4000 years ago. Its wild relatives still live in Africa and western Asia, although habitat destruction has restricted their range.

Other well-known members of the cat family include big cats such as the lion, tiger, leopard, jaguar, and cheetah (which despite its size, appears to be descended from the small cats), and other wild cats such as the lynx, puma, and bobcat.

Fossil cats

The oldest known felines (Aelurogale , Eofelis ) emerged in the Eocene. Better known is Proailurus, which lived in the Oligocene and Miocene eras. During the Miocene it gave way to Pseudaelurus. Pseudaelurus is believed to be the latest common ancestor of the three above-mentioned subfamilies and another subfamily, the Machairodontinae. This group, better known as the sabertooth cats, became extinct in the early Pleistocene era. It includes the genera Smilodon, Machairodus, Dinofelis and Homotherium.
