Minecraft wiki entry for Donkey, associated text: Donkeys roam around idly, occasionally stopping to rear, swish their tails, or lower their heads as though eating the grass. Unlike sheep, the eating animation does not actually cause any grass to be consumed. A donkey may turn to look at a player who comes near. Any donkey, even a wild one, allows itself to be attached to a lead without protest. However, if the player attempts to saddle an untamed donkey, it rears and flails its front hooves. Donkeys remain passive, even when hit.
