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, the cat family, both belong to the Feliformia suborder, along with civets and mongooses, whilst the dog family, Canidae, belongs to the Caniformia suborder. Caitofga is mistaken in saying hyenas are closely related to ferrets or weasels. These animals belong to the family Mustelidae, which is part of the Caniformia suborder. Hyenas are no more closely related to this family than they are to the dog family. Source(s): I used to be a zookeeper and have studied animals all my life.
