My fiancee and I moved into our current house 6 months ago. We have noticed two rabbits probably live under our back deck. The deck is about a foot off the ground, and is bordered by criscossing 2 inch wood slats. There are some openeings big enough for the rabbits, and we have seen the rabbits go under the deck before. We assume they are living under there? Should we be worried about this at all?
