I forgot to mention it, but according to all your predictions, the cats did come back. They "fell" (we still don't know how) down the hole into our house. Once the momma wandered around for a bit and then took them away. The second time we went on the offensive and lured one out (with bread) and caught it in a bucket. The one we got was the grouchy one! This picture of him may look sweet, but don't be fooled! I think the poor thing was terrorized because they haven't been back for a week now.
