Humidity issues in Arizona is why I held off on getting a cham for years! Until I found a species that didn't require high levels of it!! I was between Verrocosus and Oustalet's... Ultimately choosing Oustalet's. Mine do great with humidity in the 30% range and I was able to achieve this by putting a clear shower curtain around the cage and misting twice a day. I couldn't imagine trying to get my humidity in the 50-60%+... I would have to run a humidifier all the time!
