What family of mammals includes lions, tigers, and domestic cats? The family is Felidae.
Felidae is the biological family of cats, including the domestic cat and wild species such as lions, tigers, leopards, jaguars, cheetahs, lynxes, and pumas. Members are carnivorous mammals generally adapted for stalking, ambushing, and killing prey with sharp teeth and claws.
The family is commonly divided into two living lineages: Pantherinae, which includes lions, tigers, leopards, jaguars, and snow leopards, and Felinae, which includes domestic cats, cheetahs, pumas, lynxes, and many smaller cats. The exact classification of some species has changed as genetic research has refined cat relationships.
Felidae is often confused with Canidae, the dog family, or Hyaenidae, the hyena family. Ursidae contains bears. A notable exception to the usual cat stereotype is the lion: unlike most felids, lions are highly social and live in prides. Domestic cats retain many feline traits, including retractable claws, flexible spines, and specialized night vision.
