The family Felidae, which includes all cats, is divided into two primary subfamilies: Pantherinae and Felinae, each encompassing distinct groups of felids. The Pantherinae, often referred to as pantherines, includes the large, typically roaring cats such as lions (Panthera leo), tigers (Panthera tigris), leopards (Panthera pardus), and jaguars (Panthera onca). This subfamily is characterized by morphological adaptations like a more specialized hyoid bone that enables their iconic roars, along with robust builds and larger body sizes adapted for apex predation. In contrast, the Felinae, or felines, comprises smaller cats, including domestic cats (Felis catus), cheetahs (Acinonyx jubatus), and cougars (Puma concolor). Felines lack the ability to roar due to their ossified hyoid bones, though some species, like cheetahs, are capable of unique vocalizations such as chirping. Both subfamilies share key traits of felids, such as retractable claws, acute vision adapted for hunting, and a carnivorous diet, but differ markedly in size, vocal abilities, and ecological niches.
