The kitten is MIA (that's her name, she's no longer missing) and the fat, mean white cat with the spot on its head is Spooter. Sophie just doesn't photograph well. The medium sized versions are links to enormous versions.
All taken with a Canon D30 + 28-135/IS + 380EX. Forgive the odd exposures, that's me playing with the flash exposure compensation. And I really should fix the "green eye".
