As Craig already explained, your young snake is eating young rodents that are mostly "use-able" with nothing left over. As your snake eats larger
rodents that have more hair & bigger bones, your snake will have more waste to expel. So as already mentioned, there's no real "schedule" & it's rarely ever an
issue. Beautiful new snake you've got...glad to have you join us. You should also know that snakes are "addicting".
