I never used substrate when I had a rack just paper towels. My only ball python gets a piece of cypress stuck in his gums almost everytime he eats. Today he could not get it out so I had to rub it out with a wet q-tip (not very fun for him after just eating). I do not want to risk mouth rot so my question is if Eco-Earth gets in his mouth will that cause any issues? What is the best bedding to feed on that will keep humidity up?
