Felinae is a subfamily of the Felidae and comprises the small cats having a bony hyoid, because of which they are able to purr but not roar.[2]
Other authors have proposed an alternative definition for this subfamily, as comprising only the living conical-toothed cat genera with two tribes, the Felini and Pantherini, and excluding the extinct sabre-toothed Machairodontinae.[3][4]
