I love the boaphile cages but it doesnt look like theres much ventilation... Seems weird to me. Also whats the purpose of covering the sides of exoterra with paper ? is it just for humidity or let the snake feel safer? If i were to order the boaphile cage what size would I get? or should i wait until the snake i get is much older ? I would hate to buy an expensive boaphile cage just to have to upgrade it later lol.
