My cat has had a worse day than I have. I let her out when I got up at 7am, and when I had to leave for work at 8 I couldn't find her, so I left the little window in the bathroom open. I get home just before 6 and realised that, in my tired state, after opening the window I'd closed the bathroom door. There was a path of muddy paw prints leading down the window, down the wall, across the floor to the door, on the door, then around and back out the window again.
Found her outside in the bushes looking extremely pathetic.
