The utility room in the cottage has two windows: one that opens and one that does not. The one that opens sits above the one that does not. It's usually left open for ventilation while the washing machine is on. Outside the cottage, beneath the open window, there's a large utility sink. It's about four feet below the window, possibly four-and-a-half. Trailer Trash uses this as a step and then somehow manages the vertical leap to the window. It's quite impressive, even for a cat.
It was only yesterday evening we figured it out. We came back from the supermarket to find TT waiting for us. None of us could have let him in, and the small, awkwardly placed window was the only possible entrance. It turned out we'd all suspected one another. I secretly suspected there was a hitherto undiscovered entrance to the cottage - a secret passageway that the cat was using. Well, maybe hoped more than suspected. I've always wanted a house with secret passageways.
Part of me will miss the uncertainty of the last few days, wondering whether there'd be an uninvited feline making a racket and hiding behind the couch when I woke up. But not the part that likes to sleep late.
I've added a greatest hits section in the right hand column. Feel free to have a look when you get over the irony.
