I think we had voles get to a few beets, but nothing major. Before we put in the electric fences, moose would get in and pull out all the beets. They didn't eat the beets or even the tops, but would pull them all out of the ground. They would also take one bite out of every head of cabbage, but never eat an entire head. The cabbage was the real reason we put the fences in. We have no livestock either, but we never had horses; too expensive and they didn't do great when the snow got over 4 feet deep. We have friends with horses, and they would sit in the barn for 9 months eating purchased hay.
