I'm very sorry to hear that she didn't make it, but it's one of those things with rats. I love my pet rats, but after this batch dies off, I vow not to get more, because they ALWAYS die from some horrible horrible thing. Old age is never what kills them. It's heartbreaking.

Very sorry for your loss.
Just curious, what else do you breed besides rats? Your knowledge of rodents always seems to be pretty accurate
