I moved the basket. And what did I see? A bit of black and white fur?
Yes, there was Twitty. These are new bookcases and the old ones didn't have space underneath so I'm not used to looking there. He looks at me like "yeah, I've been here all this time; it's really comfy under here."
He's lucky he's a smaller guy 'cause some of the others might have gotten stuck! So Twitty was extracted from under the bookcase and stowed with his brothers. Of course, as I write this we all know exactly where he is, don't we? At least now I know where he is. For the moment. Silly Twitty Cat!!
