I personally noticed that with younger snakes under 500 grams will poop less often as they are growing. And older snakes will poop more as their not growing as fast so therefore the meals are not being absorbed 100%. If the snake is pooping alot rethink the food amount and see if that helps.

my younger snakes are pooping every 4-6 weeks on the dot. But i do not feed them large meals only a max of 60 grams a week.
