When I first got him he was in a small cage seemed pretty laid back without any sort of temper. Ever since I've purchased a bigger cage and redecorated he goes crazy if I try and take him out hisses even attempted to bite. I know most don't like being held but I have to pack him back and forth between indoors and outdoors cages and since I'm a novice I don't understand why such a dramatic change in temper. He only acts this way when inside his cage if you get out of his cage his temper goes away.
