give her some cat nip than tie a string to a celing fan that should clear up her wieght problem and if you do smoke with her hide her food or something so she doesnt eat so much when on munchies or give her a little bit to eat. and if you go into the bathroom and she starts running into the door just scream at her really loud so she gets scared and runs away and just play with her with a string or something to keep her entertained
