Yeah, I'd be worried about how he'd react... well, he can't necessarily un-snip his balls, so it would be a victory to manage to do it. About the kittens, it might be worthwhile to separate them from Miffy and socialise them better so they don't become mini-Miffys - and, even better, train an army of Miffy's kittens to overthrow him and put an end to this!
