I have kept a parsonii with dripped water without a humidifier for 3 years. I left him with my buddy when I went to Basic training and it died a couple months later. The cage I built was screened 4x4x6. I made my own screens and rivetted them together to make a box. I kept the lights outside of the cage with a heatlamp in one corner and direct access to sun in the other. I used a bush from the local nursery and pruned it to keep it from overcrowding the cage.
I fed hissing roaches and large grasshoppers. The roaches actually needed a humidifier to get them to breed.
Tuner, you had a parsonii? I have never even seen one in the states. New England Reptile had one for sale a few years back for something like 2 grand, but I never got a chance to see it. Any pics?
