too much food?

can you over feed your ball python? i was just wondering cuz today was the day i wanted to switch my bp levi over to rats, so i bought a small rat and one adult mouse. I thawed out the rat as i would normally and fed it too her, she ate it just fine (no need for any fancy tricks haha). Currently shes pacing around her tank like she does when she is hungry, so my question is can i feed her the mouse or would i be over feeding her?
thanks :)

:DI feed two items a week thats just me thoe.

I'm pretty sure that if they do eat too much it will trigger a fasting impulse. Also, I'm sure in the wild they eat more than just 1 rat when they get that chance because they never know when the next time they will eat will be. I'd say don't worry too much about it.
