Why do some people return their ball pythons?

I definitely expect to make some beginner mistakes lol, just like with any new thing. But I hope with the amount of research I've been doing that those mistakes won't be too severe and that I'll be able to correct them when they happen.

It is not a bad idea to buy the setup and get it all squared away before you get a snake. Anytime I have a new setup I try to give it a few days to get it dialed in. Then you can just add the snake when you get it.
