He is amazingly smart (for a bunny). For example, he knows he is not allowed upstairs. That is why he pretends to sleep, until you leave for another room, then he'll boot his little butt up there as fast as he can. And when you notice him and yell at him, he boots it back downstairs, runs right into his cage and sits there, looking at you: "Who me? upstairs? No, that wasn't me. I know that I'm not allowed up there. That must have been some other bunny you saw."
