Can I wait it out since it's not a tumor? I really don't want to put her down but I don't want her to keep hurting herself. Allure is about the size for her but I don't want to risk it. I'd have to CO2 her. I really like her, she's very sociable, and gets along with everyone.

I've never dropped her and she's never gotten loose. She's in a 105qt tub with the hardware cloth on the lid of the tub so I don't know how she'd of gotten a head injury. And yep the cute little friendly mink girl.
