Winter Mice?

So much for a do nothing day. Too cold to go down to the skating rink and watch hockey so I puttered around the house. We needed towels to set on the seat of the truck when delivering ribs & pierogis to the crew for supper, so after digging around for some old ones, I said what the heck. Thanks to seeing mouse dropping on the floor I scrubbed & stuck down 4 adhesive tiles & set a trap. Tell me why I have cats again?
