Venus here -
I have a very well-trained family. I've taught my mom to throw! If I bring her a 'fetch' (a coiled-up pipecleaner) she will throw it. Sometimes I have to show her where the fetches are kept, but if I meow at her enough, she'll get one for me. Mercury does not like that game so much, which is one reason that he is not as svelte as I am. Diet and exercise, I tell him, diet and exercise is the key; but he never listens to me.
