I agree - it's not really news but the media has always enjoyed reporting on the Downing Street Cat situation as a lighter way to cover politics.
If you like a conspiracy theory, you should read up on what happened to Humphrey.
I particularly enjoy the idea that he disliked Cherie so much that Alistair Campbell had to sedate him in order to orchestrate a photograph to be taken to quell rumours of a rift between them!
If you google that picture you'll see it's the most uncomfortable photo of all time.
I just wish he'd sedated a few others while he was at it.
