Because they are not very heavy, therefore being easily lifted off the ground and thrown about. Although, to be fair, they aren't the MOST affected, as all smaller animals than humans can be more easily lifted and thus are more affected than people are. The exception to this being birds, because they fly and are usually able to avoid the path of a tornado. Large animals on the other hand, like cows or giraffes, are not as affected because their weight provides more resistance to the tornadoes.
Tornado Alley gets hit by tornadoes a lot, lots of open farmland (:
