Feliformia, together with Caniformia, is one of the two recent carnivores (Carnivora).

Systematics

The order of carnivores has traditionally been divided into two suborders: terrestrial carnivores (Fissipedia), which included all terrestrial species of carnivores, and pinnipedia (pinnipedia) as a separate suborder. Only analyzes of blood serum showed that pinnipeds are close relatives of bears, and the established paraphyletic system began to be abandoned based on these facts. The predominant system divides carnivores into suborder Caniformia and Feliformia, in which case the recent families include the recent families Nandiniidae, Viverridae, Hyenas (Hyaenidae), Madagascar (Eupleridae, Herpids), promy Asian linsangs (Prionodontidae) and cats (Felidae). The basal member of the suborder is the family Nandinia, with the only recent species of Nandinia (Nandinia binotata). The origin of the first civets is dated to the Upper Eocene, the first cats appear at the beginning of the Oligocene. The Madagascar beasts inhabited the island from Africa during the Upper Oligocene to the Early Miocene. The phylogenetic tree of the feline is listed below.

Characteristics

A key morphological feature that distinguishes from cattle is the anatomy of the tympanic cavity, covering the middle and inner ear. In the case of dog-forming ones, it consists of only one bone, while in the case of cat-forming drums, the bulge is formed by the fusion of two bones, between which a septum is formed, so the bulge is usually two-chambered. The problem in this case arises with the classification of the extinct family Nimravidae, in which the bulge was either cartilaginous or lacked the true septum observed in other carnivores. Nimravids are classified as tribal feline, sometimes as tribal feline, or as tribal representatives of beasts.
