Is it necessary? My girlfriend has a Cham living in my house so I don't take care of it too much, right now I have a regular 60 watt house bulb for the lgihting source. Recently we have noticed the cham shaking a lot almost as if his bones have weakend or somthing along those lines. Could it be from the lack of UV lighting? I said no because none of my other animals use them and has been doing great. Any help is appreciated.
