Young snakes are eating smaller, younger prey that is mostly digestible. As snakes grow & eat larger prey, that prey has larger bones, more fur/feathers, and possibly
some indigestible stuff in their own gut (like seeds, etc) that ends up making more "roughage" & thus more stool.
So a baby snake eating pinkie mice may take a while to make very much stool...see? You tend to see more urates than stool at first. You'd be surprised at how
often we are asked here if someone's young snake is constipated.![]()
