I have a similar reaction to children, and a tendency to head for the door
I don't think you should worry too much about ethics in this case Beth, these two weren't going to be bred from (again) so are a kind of rescue. I know loads of ex-breeding queens get dumped and end up in rescue, you're just cutting out the middle man. At least now you've agreed to take Aurora they won't be tempted to try her with one litter, so you've stopped at least one set of kittens reaching the market. No, well done you, I think you're brilliant and hope the beautiful Aurora is as happy as her Mum will be to see her. Does this mean the kids get one each ?
