is this a healthy weight or not???

well i have notice her last 4 mice i gave her she downed them pretty fast and leave little no no buldge on her body when she done u think maybe its time for small rats???

If she will take them. if you know that shed weighs 316 grams, then you can determine how much you should feed her. The rule is 15% of her body weight, so you should feed her 47.4 grams of rodent (316*0.15=47.4)

It doesn't need to be exact (+/- 5 grams isn't going to hurt)
