In addition to this, before I got a blood python and was doing research I read that they are known for going months without pooping. A theory of this is that they “hold it” because they are such large, heavy bodied snakes that are ambushers. Because of their size, they’re not very active and pooping often would cause both their living quarters to be dirtied and their scent to be smelled by prey. Could be similar to what Bogertophis has said here
