Minecraft wiki entry for Goat, associated text: A goat that is not on a honey block can jump up to 10 blocks high and 5 blocks wide (on an even surface). This usually happens if the goat is trying to cross an obstacle like a small hole in the ground or powder snow, sometimes even in a narrow jumping area. Goats take 10 less fall damage and avoid walking into powder snow. Once a goat performs its long jump, it cannot perform another for 30 to 60 seconds. A goat also never voluntarily jumps more than 5 blocks down, though a goat can be pushed off a higher cliff by another mob or a piston.
