I’ve had my male veiled chameleon for a few weeks now. Yesterday I let him do a little “free roam”. He sat on a plant on the outside of his enclosure all day and slept in it. I finally got him back in to the enclosure. (I put him back so he could get uvb) It took a long time, but after it I had to leave. Then when I got back he was crawling on the floor of his enclosure as a dark color. He seemed “happy” in his enclosure before. I’m not sure if there is any thing wrong. Any help appreciated.
