An animal engine is a machine powered by an animal. Horses, donkeys, oxen, dogs, and humans have all been used in this way.[1][2][3][4] An unusual example of an animal engine was recorded at Portland, Victoria in 1866. A kangaroo had been tamed and trained to work a treadmill which drove various items of machinery.[5]
