I do understand that it is unnaturally large from their hole in the ground however they also naturally live wild and free to roam where they choose. On humidity I have that taken care of with the ultrasonic mister that is set to go off every 4 hours for 30 secs and it works beautifully in a 40 gal breeder tank and its set to go off every 8 hours for 30 secs in that and maintains 56% humidity on a constant basis
Along with multiple hides and shorter climbing objects which my girls are quite fond of atm the habitat also includes a feeder section secluded from the rest of the cage that is 1x2x1 for feeding her in although it sounds like a lot in the end I will post pictures it is going to be less space than you think a 40 gal breeder tank is recommended for an adult ball python and those are 3/1.5/1.5 approx so the overall area being added isnt much larger than that especially when you take into account the sectioned off 1x2x1 feeder area
