This is her with her half brother Marmaduke (I can't remember his full name):
He was half her size then, but he's much bigger than her now. I think he also won a champion award equivalent when he was a kitten, but I don't think this counts once they become adults.
She stopped showing them, when Bubbles had got two black marks for scratching or biting a judge (or something like that). If she gets a third, she is then banned from any further shows!
This is him by himself, and slightly more upright.
