Hi i just got a new male veiled chameleon. For it size y assume it is aprox 4 month old. I have his cage outside in my backyard it is very strong so predators dosnt worry me. but could it be okay if it gets the all rain? or should i cover the top of the cage or atleast half of it. also since it arrived it have been like trying to get out of the cage in the bottom or in the top of the cage. it has allot of plants in there. 2 large ficus, one palm tree and a phottos. will this behavior stop when he get used to the cage?
