Housing for a single ball python?

[Bogertophis]

Totally agree with getting a feeding record (3 or more times prior to you taking possession of ANY kind of snake)...that's really important, especially for your
first snake, that you not buy one "right out of the egg".

I also agree that a smaller enclosure will work best at first for a hatchling...they are instinctively shy, as predators of all kinds take them easily in the wild.

Whatever kind of cage you decide on, be sure to have it up & running (heat controlled by thermostat) for a week or more prior to your snake moving in; that way, if heat & humidity need tweaked, you aren't stressing the new snake, and if you have to buy/order something, you need time to do that.

When you get the snake, do not handle it...let it be a snake first while it settles in & has time to eat at least 3 times for you, easily & at normal intervals (weekly). There is no rush to 'tame' a baby snake, but if you handle too soon, they may refuse food & not do well. Eating is "job #1"

Be sure that you are watchful for mites for at least the first month (eggs take that long to hatch out): don't underestimate mites, they can & do kill snakes.
This is also why it's best to keep the initial enclosure simple: white paper towels for substrate, plastic hides, water bowl...no plants or wood/fiber decor,
because you'll just have to throw them out if mites come with your snake, & they make it harder to see any such health issues. That's really what's important.
