You can probably get away with that space for a year or maybe two but it's gonna be a tight fit if that's a long term or permament space. You have some potentially very large snakes to house. The scrub, retic, Indigo, and Cribo will all need 6-8 ft. enclosures with preferably 18-24 inches of vertical space. I would definitely suggest converting to stackable pvc enclosures. They'll help you maximize your space in the long run. I'm in the process of upgrading enclosures now. I'm a big fan of AP cages and will probably stick with them exclusively. I can get a little OCDish too. Balance, Uniformity, and Symmetry are very important to me.
