I just caught my chameleon Mahasen eating dirt from the dragon tree pot she is on , I think this is not the first time she does it because I've seen her going down and staring at the dirt I was thinking she would do it when she wants food , knowing I've fed her two hours ago 1 giant mealworm dusted with calcium without vitamin D3 and 4 crickets, dripped water for her she didn't drink and misted her area , I usually feed her wheatgrass she loves it and I don't use calicum with V D3 , and sometimes I dust her food with reptil vitamins why she is eating dirt ???
