Two Level Climbing Terrarium

[aasagan]

I built this originally for Bearded dragons but hadn't ever owned one and more experienced keepers talked me out of it thinking clumsy dragons might fall from the upper level. So, I found a great Russian rat snake, Felix, pictured below and he'll move in here when he gets a little bigger. He's my first snake. Any other species you think might do well in a climbing cage like this? Snakes or otherwise? Thanks.
