and his tail, "Dammit".
It's not annoying enough that Bobby scents everything he comes into contact with. Either by rubbing his face on it or peeing on it. (You can always tell when he's been in a room by the wet drops on the floor, he sprays.)
But then there's his tail. That tail is alive with a mind of its own, but no way to control itself. It's forever knocking things over.
He's such a friendly cat.
