Chameleon Outside.

I live in an apartment complex and my patio is enclosed with walls. I want to leave him outside all day so he can get plenty of natural UVB and UVA. He is in a reptarium so is it ok that i leave him outside during the day and bring him in at night?

I never recommend bringing your herps outside unless you are always there to watch them.
But you just need to use your best judgment.
