Ms. Flippers reported that she heard the sounds of retreating Raccoons a few nights ago. She could hear them coming over the shed and ran to make noise at them, but they were already retreating across the fence.
I was afraid to believe her, but last night as I sat on the deck, I heard the rustle and patter of tiny (and not so tiny) feet through the bushes and along the fence. Soon the footfalls ceased and there were rustling noises - which were followed soon after by the sounds of rapid retreat. There was skittering along the top of the fence and a great crashing in the bushes.
Long live the Yard Sentinel!
