I thought the general rule for weights was 10-15% of the snake's weight? 850* 10-15% would be 85 - 127.

Granted that I didn't plan on jumping her up this soon, but I misjudged when I ordered online last. I'd like to avoid ordering another round of the smaller ones if possible since I think she's going to out grow those before she goes through another bag of them.

Is this really unhealthy for her?
