Need reassurance

[kreaturekeeper]

Hi there, I know bp going off food is not uncommon. But I have a 1.5 year old bp female that I have had for over a year. She has always loved her food with no problems, and I handle her every day. About three months ago I tried giving her a small rat because she was eating multiple mice at each feeding. She gobbled it in seconds. It was a much larger sized rodent than she was used to but she ate it fine. Then she stopped eating. I thought she was full so I waited 2 weeks to try again. Both mice and rats. She didn't eat for over two months. Then one day she took a jumbo mouse after reheating it 3 times. I was so excited!! And now she has not eaten since.... I don't think she has lost weight yet but she is definitely not getting any bigger.
I have not handled her in over three months and miss her very much.
Any thoughts about the rat messing up her routine and why that would kill her appetite?
I'm getting a tad impatient now
Can anyone help with suggestions?
