His main occupation seems to be the Vocation of Annoying. He's started bullying MCat, who can look after himself. He ambushes MC when he's using the tray. Right now he's galloping through the house doing the sideways shimmy boogaloo at MCat, whilst making excited noises.
I can't go to the loo without him following to steal loo paper/shower gel so he can chuck it down the stairs, or run away with it.
I suppose he's going through his teenage rebellious stage.
What to do to with this naughty creature?
