How much does she weight?

Reason I ask is that fuzzy rats and hopper mice are generally used to start hatchlings who quickly move to bigger preys in a matter of weeks.

Fuzzy mice and pinky rats are way too small.

You should feed something equal to her girth size (widest part of your BP's body) every 5 to 7 days as they grow and than every 7 days.

Also if rats are what you want to feed I would suggest to stick to them and no longer offer mice.
