My cat Beauty sits when you ask her. I don't know if this is a trick or just a way of settling down to receive the treat she knows she is going to get if she sits. Beauty always makes me smile - except when she comes hurtling out of nowhere, without warning, to land her substantial weight on my chest when I am reclining in bed: ooooofff! A black blur and then - a huge, furry Beauty in front of my face. Well, okay, so when I recover from the surprise, then I smile, because by then she is butting me in the face with her head.
