Its rough sometimes, keeping ball pythons. Don't give up, they will eat sooner or later. How often are you offering food ? I've had problem feeders that would not eat. So I stopped offering food to them every week. Some times if you offer them food often. They seem to train themselves not to accept food. So space the offerings out more and they may eat for you. Also try keeping a different type of snake say maybe a boa. Those guys eat and interact well.
