Nice setup! I too really like the plant next to the cages... looks "jungly".
We're in the process of moving into our first house and I've claimed the downstairs spare bedroom as my critter room. It will have to house the rats, geckos, and snakes, but at least it's dedicated space. We've already painted and I'm having good vinyl flooring (faux wood grain) put down so it'll be easy to clean. I'll have to post pics too when it's finished. Of course, I don't have an;;y awesome pvc cages like yours yet, but that's coming hopefully this fall / winter.
