Other authors proposed an alternative definition for this subfamily: as comprising only the living conical-toothed cat genera with two tribes, the Felini and Pantherini; thus excluding all fossil cat species.
The members of the Felinae have retractile claws that are protected by at least one cutaneouslobe. Their larynx is kept close to the base of the skull by an ossified hyoid.
They can purr owing to the vocal folds being shorter than 6 mm (0.24 in).
The cheetah Acinonyx does not have cutaneous sheaths for guarding claws.
The term Felini was first used in 1817 by Gotthelf Fischer von Waldheim, at the time for all the cat species that had been proposed as belonging to the genusFelis.
In 1917, Reginald Innes Pocock also subordinated the following genera to the Felinae that had been proposed in the course of the 19th century: Lynx, Puma, Leptailurus, Prionailurus, Pardofelis, Leopardus, Herpailurus, Neofelis and four more.
The Felinae and Pantherinae probably diverged about 11.5 million years ago. The genera within the Felinae diverged between 10.67 and 4.23 million years ago.
Today, the following genera and species are recognised as belonging to the Felinae:
