THE BIG JUNGLE GYM.
The shelves function like a ladder in this arrangement...
Only the top two are covered with mesh. It took a bit of watching iguanas keep trying to climb up directly into the mesh to come to the conclusion that there's no good reason to put mesh on every shelf.
I've noticed that 90% of the cage time is spent on the top big shelf anyway.
A nice addition would be to add some silk vines or greenery around a lot of those pvc poles against the back walls. That would help make it jungle-like! Just make sure that any greenery you use is either edible or can't come apart and create an impaction hazard.
"Very well thought-out designs".
"Great cage. Thank you".
