All the info above is great. Some recommended things like aspen, some recommended things like paper towels. If your snake is in a glass tank: use aspen. If your snake is in a plastic tote: use paper towels. The reason I say that is because paper towels do not hold in as much humidity as Aspen bedding. Glass tanks are usually bad enough at holding humidity as is, so it's good to try and finds little ways to raise it. (E.I live plants, humid bedding, misting, etc).
Pathos are perfectly fine for Ball Pythons, but I must warn you: Your snake WILL destroy it. Lol
Welcome to the site, the hobby, and congrats on your new Ball Python.
