I have one of these cages for my veiled and it is great. They also have a removeable plastic bottom that comes in handy for a variety of things. Me personally, I cut a 3 inch hole in the middle and re-screened it with some extra screen and duct tape. Then I put a humidifier with a PVC pipe connected to it going straight up into the cage. Instant humidity!
Also, I have a reptile carpet that absorbs water but when it gets too absorbed, water starts to drip out of the hole I cut and BACK into the humidifier!
