We got a baby veiled chameleon 3 weeks ago. He seems to have been doing well. He is in an 18 x 18 X 24 habitat with UV bulb and heat lamp. Automatic mister. Humidity 80%, temp at basking 78. Fed baby crickets dusted in calcium every 3 days. Lot of artificial plants/vines and a living pathos. He has started to shed the past 2 days. Tonight he is sitting at the bottom of the habitat. I had read recently that this is a worrisome sign. We don’t have access to a reptile vet tonight but will try first thing tomorrow. Any input is greatly appreciated.
