Also don't stress to much. Things you need to be worried about with BP's not eating. Is he losing weight fast? was he bitten by a rat or mouse before. BP's IN THE WILD MAY ONLY EAT FIVE MEALS A YEAR>>>>> they spend up to months on end hibernating. It's winter in December. I have a few Balls who shut down mid- September, and then gore themselves, in April till September. Check to see if your temps are good try raising them a few degrees for a few days and see if that gets him going. The main concern is him losing alot of weight very quickly. if he is then something else is wrong and get him to a vet. if he isn't then relax, warm him up a bit more and let him be a snake.
