My veiled chameleon has been acting very strange. He stays in one spot for most of the day, he does not exhibit much interest in food, he moves around sluggishly and I've noticed him sleeping a couple hours earlier than normal. I've been watching him for about a month, but the behavior became much more profound after I completely cleaned his cage. I added some thicker sticks and changed the vines around a bit, but nothing too drastic. I have witnessed him trying to drink more, but I mist him 3-4 times a day and I have a dripper that drips all day while I'm at work. As far as supplements go, I give him Rep-Cal Phosphorous free and D3 free Calcium at every feeding and Reptivite w/ D3 once a week. I'm not sure where I'm going wrong. Any suggestions?
