So I got my ball python about 2 months now and the pet store guy that I got her from told me that she is 7 months old,she was shorter when i got her and now at 9 months she is about 35 cm...I guess she wasn't fed well at the pet shop...should I worry?I feed her 1 fuzzy a week...If I want her to grow bigger faster without harming her how often should i fed her and how much?
