My BP is about 30" long, he weighs around 700g. I feed him a f/t small rat or 2 large, fat live adult mice. To me a hopper is very small, about an inch long, about 12 to 15g. A 2-inch long mouse sounds to me like a small adult. It's hard to tell without seeing, I think that's why people go by weight on them.
But yeah, if she's acting hungry, feed her again.
