I'm a firm believer that hunger ALWAYS wins in the end and I have yet to see a healthy animal starve itself to death. If you have a finicky feeder that won't eat weekly then try offering food bi-weekly. If they're still being stubborn then offer food every 3-4 weeks until you find the sweet spot. One of my carpet pythons was frustrating me to no end with her inconsistent eating habits. She LOVES chicks and will eat them anytime, she eats mice sometimes, but she would rarely eat rats. Once she started only getting food every 17-21 days she stopped refusing her meals and ate whatever I offered. She's eaten two rats and a chick for her last 3 feedings and she's hanging out near the front of her enclosure more often looking for food. I used to worry whenever a snake refused food. Now, as long as I know their temps are good, and they're not sick, I just wait them out. They always get back on track sooner or later. Best wishes with your BP.
