Bird-napping sounds a bit dastardly, but probably effective, at least for the short term. I'm sorry to say that I don't think most people like Miss B. ever really change their spots, though. (I say this because I am effectively this way, and only barely civilized through social contact.) They can keep up the charade of orderliness for a little while when people are looking, but when some other stressor comes along, it's too difficult to control it and they spiral back down. I'm not sure there *is* a long term answer that won't feel invasive and/or coercive, honestly. Yet you are such a dear for caring about both Miss B and Sweetie.
