AIBU to be pissing my pants laughing at my cats?

[ripsishere]

Both are sitting on the back of the sofa, one is chattering his teeth to something, the other is glaring at their friend.
The friend generally knocks around in the garden with them, today he is sitting on my car (in the rain) having what appears to be a staring contents with the greyboy.

My kitten has now learnt how to do roly polys'. I think at first it was an accident...but she now seems to feel very clever and won't stop doing them.

Not sure what a contents is, I assume I meant contest.
Today they are fighting each other. Incessantly. I imagine that if they weren't brothers, one would be killed.
