They go when they want/need to go. Sometimes it's weekly, sometimes it can be once a month. Just depends on the snake and food item size.

Mine hasn't pooped for a good solid month and a half at least, she always poops after she sheds. This brings up another question for me, for those of you that have a snake like mine that doesnt poop weekly, do you still change the bedding every week or two even if theres no poo/urates?
