With Ball Pythons, if they are eating and shedding routinely then they aren't "stressed." Ball Pythons spend 90% of their lives in Rodent burrows usually only coming out to eat, drink, or bask. I think whether we all keep them in tubs or large habitats, as long as they are doing the things they should then they have a good quality of life. Love all the pictures above, and set ups with the chair. Very neat idea.
