If I were you I would still be a bit concerned. It sounds like you are underfeeding. At that size I would be offering 10% to 15% of your snakes weight every 5 days. If you don't know what your snake weighs you should go out and get a scale. For the record if you are going to breed a male BP you wouldn't fatten them up. You would want them lean. If your parents are complaining about money you need to get a source of income. When I was a kid I was a paper boy. It sucked but it was a source of income.
