Is my ball python underweight?

[Daybreaker]

I needed to assist feed her because she wouldn't eat anything. I used a fuzzy, because I want her to get used to it. I have 5 frozen hopper mice in my freezer that I will try to give her in three days.

How long have you had her? What was the previous owner/breeder/store feeding her? Have you tried live? How long has she not eaten for you?
