We finally managed to get Sirius to be up at a time when we were both free, so we managed to get a Christmasy photo of him. This was the best of our attempts (hamsters aren't the easiest of animals to photograph). Sorry about my hands being in the shot, but without my hands there he kept turning around.
The card we used as a Christmasy background is the Christmas card we got from my brother Carl and his fiance Rachel. The tree on it is tactile, so I thought it would make a perfect hamster sized Christmas tree.
