Most species in this family sever the spinal chord of their prey with their canines. Species in this family have rounded heads and short muzzles. They have excellent eyesight and hearing and a good sense of smell. The big cats in this family, like the lion, tiger, jaguar and leopard, can roar, but they can not purr.
The families Hyaenidae and Felidae both belong to the Feliformia suborder, whilst the Canidae family belongs to the Caniformia suborder-therefore, hyenas are more closely related to animals in the cat family than those in the dog family.
