He's an exceptionally smart cat. Seriously. He's actually sort of a pain in the ass because he's hard to discipline, because he tests all deterrents until he figures out how to get around them.

I've got a smart dog, too. It wouldn't take me long to teach her to open doors, except that then I wouldn't be able to stop her from raiding the cabinets. Really, she would have made a great service dog if she weren't so self-interested. I worry more about what she might learn in spite of me.
