It was finally warm (22C) enough to take Steve outside for a outing. he is a panther Chameleon approx 17" long. He hung out on my shoulders and head and took in the suns rays. he also gathered a crowd of curious children and adults wanting to know all about him. When I took him inside he was a very different chameleon. he was active and just wanted to move about perky for a subdued chameleon. yes I have to agree nothing can replace the Naturral effects of the Sun. His appetite seems also to be on the up swing even though it was no problems before.
