Good feedback so far guys. Here are my notes and obviously this is very subjective:

- Colubrids do in fact tend to poo more, have strong smelling poop

- Ball pythons seem to be the least smelly

- Coconut husk or other absorbent substrate seem to make the difference instead of paper towels

Anyone have feedback on MBKs?

Any advice on not getting your snake to poo on you or poo outside of cage? The first one seems to be when you get it as a baby, don't just put it down or put it back in it's cage when it poos. Then it becomes learned behavior.
