Ball Pythons are not quite a simple to keep as a cornsnake, although they can still be a great novice snake. So long as they are healthy, captive bred (or in many cases captive hatched as well), and proper husbandry is practiced, there is no worries

And as Jeff mentioned, it is fairly common for many ball python's to fast during the winter. Good luck convincing your parents, and welcome to ssnakess.com! :bounce:
