Are hyenas related to cats or dogs?

Hyenas are related to both cats and dogs, but they are more closely related to cats than they are to dogs. Hyenas are members of the Order Carnivora, which includes both the dog-like and cat-like mammals. Dog-like mammals include bears, seals, otters, weasels, raccoons, pandas, and of course dogs. Cat-like mammals include the big cats and small cats, the mongooses, and the hyenas.
