Ever since I got my snake about 4 months ago, I've been feeding her regularly every 7 days. (Sometimes on the 6th day if I notice her roaming around her enclosure all day.) However, I don't feed her during her shed cycles. She's also about 9-10 months old. She's never refused a meal either, at least not while she's been with me. Any way, I know that when a BP is underweight, you can see its spine pretty well. I've always fed her meals that are the size of the largest part of her body or a tad larger. In other words, there's always a "lump" where the mouse is. Even with this feeding schedule, her spine is still sticking up. Should I start feeding her every 5 days, perhaps? I'd take pictures, but I just fed her a few hours ago and don't want to disturb her.
