Ball Pythons not eating is one of the things that drives keepers nuts. It can be frustrating for both old and new keepers alike. So with all that said here is my only nugget of wisdom. Keep offering food, try different foods mice, rats, live, f/t. Try offering at midnight try a different day. Your willingness to keep working will pay off.. I have a mojave and a het pied that only ate ASF's for years.. they bred and poof now they are rat machines. go figure..
chin up and keep plugging away, we all go through it..
