I don't have any photos, but this pencil drawing I did (courtesy of my photo gallery) of Sebastian, my mom's Siamese cat (RIP).
He was rather standoffish and didn't let too many except my mom and me get near him, and had a streak of mischief; one of his favorite things was to hide behind their barcalounger and then pounce and nip my mom on the calf when she'd walk by. He didn't bite hard, but cats have pretty sharp teeth so I'd hear my mom bitching at him while he scampered off somewhere.
Other times the cranky old bastard would hiss and swat at my German shepherd Dino, then ten minutes later he'd be curled up laying down next to him.
