Just keep a tranquilizer gun handy. If relatives or neighbors start disappearing and she starts ordering a lot of "how to build a giant barbecue with rotating spit in your backyard" books from Amazon and begins to look at you in a decidedly different way, just "trank" her and drop her off at the Zoo. She'll have a nice snack there and will be fine for probably several hours. :-)
Next day, a new Zoo.
and stoats?
barely a meal....
