Hi there - If your fuzzy heads persist on grab/climb a barricade (like plywood in the door frame), there is a $2 solution to baracade climbers. It looks like a plastic pipe/tube. It is split down the middle to put over a curtain rod or shower curtain rod. Home Depot had it, so did Walmart. Just slip it over the top of the plywood/plastic and they can't get a toe hold on the slipery, round plastic <hehehehehehe>... Nan and gang SuperSnooper - rats!! can't get over the baricade Hershey - can't get under either! [Posted in FML issue 2194]
