Severely nippy BP!

[Moose84]

She's on medium mice at the moment and for her size, they're inline with her body weight. She just broke 400 grams or so around October. I plan on ordering rats but she's a petsmart snake so I'm not sure how well she'll adjust. I'll probably get a rat pup from my local mom and pop pet store nearby to see how she handles it.

Knowing that the snake is being underfed is definitely contributing to her being "Severely Nippy." A medium mouse is at most 13-15 grams.. That snake at 400+ grams should be on minimum rat pups/weaned rat closer to 30-35 grams.. In no way is a medium mouse inline with her bodyweight.. I would try an appropriate sized meal for a few weeks and she will probably calm down. That is typically when they start growing OUT of their nippy behavior not going into it..
