What is this?

I made a decision a long time ago not to write too much about the cats. Or post too many photos. I think they are pretty awesome (the cats, I mean) but this is not a cat-blog. I think I've done pretty well, they do appear here every now and then, but not too often. So, after saying this, I feel like I can show a few photos.

I got them a new toy, a fabric tube with some toys attached.

They seemed a bit confused at first...

...but did get a hang of it after a while.
