Our landlady and Chris decided I was crazy. It was certainly not a bat. That was not 'bat' behavior. So I said "What about a flying squirrel?" I mean, it was fuzzy, and had wing-like flaps. If it is not a bat, then it Has to be a flying squirrel. This suggestion was apparently funnier than the idea of it being a bat. SO I dropped it. Well! Guess who came to visit:

That's him alright. Sittin' atop our shower. God, was he cute. And he was in fact a Northern Flying Squirrel. I wanted to keep him forever and ever, even though he was a total party animal, and when we locked him in the bathroom over night - with the window open, hoping he would find his way out, he trashed the place.
Of course, he did not leave. In fact he camped out in a toiletry bag that I had not yet unpacked from our trip to Boston the weekend before. I didn't realize it until the next morning, when the cat is Very interested in the toiletry bag. The next thing I know there is squealing and thrashing and there is a squirrel up on top of the shower curtain again.
