I've heard from someone that tapeworm eggs don't die when they are frozen. I have never feed her live and I'm sure I don't have mice/rats in my apartment that she could have eaten when she escaped. I trust the place I got her from 100% so I'm sure she didn't have tapeworms when I got her. That means the only way she could have gotten them was from a f/t rat. I've heard some pretty horrible things about the place I was getting my f/t rats from lately too.
Again, I can't prove where she got the tapeworms from, so I will not name names.
