alright, read the caresheet..but what i would say you need, in a short list...

41 qt tub

Heat source (UTH most likely)

Thermometer and Hydrometer

Substrate (I prefer Aspen)

2 hides (one for the warm site, and one for the cool side)

Dimmer or Thermostat (Thermostats usually work a little better)

Water dish (I have never gotten one of the ncie rock ones, but i use a sturdy bowl)

Clips for the tub (make sure you're little one doesn't get out!! Snakes are so good at that )

Food (the largest part of the ball python, girth wise, should match the largest girth part on the rat or mouse)

A spray bottle (it helps with the humidity if it is lacking)

and...the snake...


that should be a good shopping list for you, but, i could be forgetting something (i do that a lot), just read the caresheets
