See the squirrel. He/she may be the one that chewed through my screen in the kitchen last fall. I had a box of nutter butter cookies right under the window. When I came into the kitchen -- there he/she was...on my counter top. There were cookies in the sink; bottles were broken on the floor. We both got very scared and he managed to get out of the screen - the way he came in. But he came back 2 more times -- eating through the newly repaired screen.
He stays outside now. I think he learned his lesson. Did it ever occur to you that a wild animal would chew through a screen to get inside your house? Beware! Don't leave cookies under the windows! It's just too tempting for them.
