Night Owl Arnold

We still have a problem with Arnold in the middle of the night, well around 3 to 4 in the morning. This is the time when Arnold becomes his most vocal. He also plays with the Venetian blinds and the screens. We keep the blinds up even though I am sure the neighbors think we are exhibitionists and we definitely need to do something by the time the leaves fall from the trees. But it is hard to stop Arnold from scratching at the screens which on our windows are on the inside. Hubby had a plan. He took our Vornado fan and cut long streamers of newsprint and taped them to the top of the fan. He placed the fan on the window seat facing the trouble spot. He has a switch which he keeps under his pillow. When Arnold scratches at the screen he flicks on the fan. It startles Arnold and he dashes away for at least an hour.
