She weighs 376 grams empty, I feed her 2 adult mice,every 5 days, which comes up to 40 grams rougly give or take..

The petsmart I get my f/t doesn't offer a small rat. They go from adult mice, to medium rat, and she isn't quite thick enough yet for that it seems surprisingly.

I'm spend.. 25-31 dollars every 20 days to feed her, can't quite remember 4 large mice in a box, I buy 2 boxes at a time.. so 8 mice last me.. 20 days with a 5 day feeding schedule?

Should I be going it about it different?
