A mouse with angel wings?  I'll tell my cats about that!  I kept them out of the basement this winter to give the mice a rest because they just come in to stay warm!!  Actually we've only had 3 the entire time we lived here, and the cats brought them all upstairs to show us, 2 survived and were put outside but I think they went to mouse-heaven soon after.  They also brought 2 chipmunks upstairs, one survived and was also put outside, it was still in great condition, just frightened and is probably still very much alive, living under the back steps, I put cereal under there for it.  They all love me, I have the best-fed varmints.
