Door Scratcher

My neighbor called me when I was on my way home from work, she was concerned because she could heard Snoopy scratching at my front door pretty hard. When I got home, not 30 mins later, I found him sprawled out on my bed without a care in the world. He may have heard someone in the breezeway, he tends to scratch at the door & sniff at it pretty hard when that happens. He may just have had to go out and clear his bladder. The house was fine when I got here, and he was too.....so I guess I'll never know.
