Hyenas are famous scavengers, but they actually kill and eat several birds, lizards, snakes and insects. In Africa, hyenas and humans come in contact so frequently that the Maasai people actually leave their dead to be eaten by hyenas. However, the hyenas also raid food stores and crops and often kill livestock and sometimes even humans. Because of these incidents, the hyena is thought of as a pest. While many think that the hyena is related to the dog, it's actually more closely related to the cat.
