Squirrel Attack

I heard this awful scratching at the screen window behind me. It sounded like a cat was trying to get in. I live on a high second floor of an old house. It wasn't a cat. It was a squirrelly squirrel. he wasn't very afraid of me or the dog either. I clanked some bottles together and he leaped onto the wall of the back staircase like spider-man. He stared back at me for a while I hissed and he took his time going back down. I hope he doesn't figure out that there is no screen on the sun room!
