Just got a 3 year old panther chameleon from a friend of a friend. I have another that is thriving. But I wanted to get some advice on this one. The previous owner never once gave vitamins and only dusted with plain calcium 1 time a month. Also never gut loaded feeders. Should I give extra vitamin dosages to start? I use reptivite. He keeps his left eye shut for all but about 5 minutes a day. He also has terrible aim.
