Lions are carnivores and eat most animals they are able to catch, but they prefer large, hoofed animals such as zebra. They have also been seen hunting buffalo, impala and giraffes.
Lions are also able to bring down much larger prey, such as hippos, rhinos and elephants. Smaller or young lions have been known to hunt and kill mice, hares, small amphibians, insects and birds. Lions that are kept inside zoos are often fed large pieces of beef, horse and sheep, as well as whole rabbits and chickens. Bones are sometimes considered treats for lions in captivity and are given a few times a month. Usually the bones are knuckles, femurs and shank bones from cows.
