He fully swallows them, no regurgitation, but i have yet to see and feces or urine in his enclosure. He has his UTH with thermostat that stays at 86-87 degrees. Aspen bedding and clean water every night. This is my first ball python so it does worry me just because i read online that they should poop every 3-5 days after a meal. Its been 3 weeks. If anyone can help me out on what to do or if hes fine just let me know please. Sorry if i sound like im worrying to much but i just want to be sure hes fine and reassure myself. Thanks
