I know I seem paranoid about this boa with all the questions I post here, but I can't seem to find the info ANYWHERE.

I have a 1.5-year-old female BCI. She's about 2.5 - 3 ft long, give or take, and currently taking one small rat every two weeks. I thought she was looking a little thin compared to when I got her and I can feel her spine every now and then. I know those are signs for an extremely underweight ball python, but I also know balls have a higher BMI than boas. Anyway, I just weighed her and she registered 17 oz/~482 g.

The internet and people here say her feeding schedule is appropriate for her size and age, but she just looks skinny. The only weight guidelines I can find are for adults. So is 482 g a healthy weight for her? If not, where should she be at?
