Sébastian Schrödinger Halliday
his flickr page you can see one shot with the flash on and how green his eyes are.
It turns out the woman who logged in in at the RSPCA is Spanish, so he is not Sebastian but Sébastian. He was found a stray, having been run over, and is recovering from a fractured pelvis. Not that you'd tell from his curiosity about my bedroom. I've just left him for fifteen minutes, so he can investigate the room on his own.
