My mother doesn't want them kept in our house in general, separate freezer or not. :/ It's unfortunate but I have to deal with it for a while.
I'll probably just keep feeding her on mice until I can find a pet store that sells f/t rats. There's a few around that I have yet to check but going to our local Petco is easier and more convenient. I'm not in any rush to switch her to rats just yet. Good luck with switching your girl, though!
