I started handling my Cham a few days after I got him so he had time to settle into the cage. However I got very lucky and my panther Cham is always wanting to come out his cage and be handled. I think the best thing to do is try to handle him but if he is stressed just leave it
I live in England so don’t need to worry about him being too hot as I only get him out in the garden for a few hours when the weather is good
I know for places in America it is different
My Cham sits outside in a cage he loves it. Now and then I will pour water over him and the cage to make sure he is drinking and keeping cool. I personally think it’s very good for them to take in natural light. I don’t see any problem with having them outside as long as the weather is hot...
