haha... my rats try to pull me into their cage... they don't really steal things though(i taught them the ethics of ratty humanity lolol) ... I had a peach faced love bird a while ago and she used to terrorize my guinea pigs, she'd fly into their cage and steal their food, peck at them so they wouldn't come near her.. it was quite funny, ive got pictures somewhere, but so far the most my rats have stolen was food..
