I suppose it was inevitable

[sesquipedality]

Nineve seems to have escaped. I'd left a window open, and I can only assume she took a golden opportunity. However, she doesn't seem to be making it back. I've had the doors open all day, but no sign of her. I am getting worried. Particularly since she must've got out the front, which only leads out onto the road area. I know she's a smart cat and will probably be back in a day or so looking smug, but I feel worried nonetheless.
