I love it! You open the door to let them out. They take one step and the cold air hits them. They pause, sniff a time or two, sit down and contemplate. All the while the cold air is rushing in the door, you're standing there in your pajamas freezing your tushy off while they decide on in or out. Eventually they turn around and come in and go curl up in a nice warm corner somewhere while you're left with frozen toes and a cold house.
