... He is on shavings as his substrate and has a water bowl, a tree hide, and a rock hide.

Just was wondering what kind of shavings you're using as substrate... as suggested coconut husks are fine, as are aspen shavings and good ol' newspaper, and there are many other options. However, commonly sold pine and cedar shavings are toxic to ball pythons and shouldn't be used. So please make sure that your substrate doesn't contain any pine or cedar.

I've enjoyed using a fine aspen shaving in my tubs for the past year or so. Great for spot cleaning with a nice woodsy smell. Just my opinion.

Best of luck to you.
