You need to get him set up properly with the right temperature gradient and plenty of hides. Leave him alone for 5-7 days, and then try feeding him a hopper mouse or rat pup. Do not leave a live feeder in with him for more than a few hours. He is probably very stressed from having that mouse hopping around his cage for 3 days. Remember, a hiding ball python is a happy ball python. Good luck with your new addition!
