do females tend to go on more aggressive feeding habbits during or before breeding season?

i started putting my male pastel in with my female normal these past few weeks and she's not aggressive to him, actually cuddles up with him alot :-)
but she is in a constant strike possition when someone walks by and she just ate 6 lg mice a couple days ago and i know if i put another one in she'll eat, she normally only is willing to eat about 4 max.

is it normal for your girls to want to eat more before or during breeding?
or is she getting ready to ovulate, or developing follicles maybe? maybe she is just wanting to put more weight on TO breed?
should i offer food or keep her on her normal feeding cycle since its a larger amount of mice a weel?


any input would be helpful.
