I have a 6 month and a year and a half old nosy be. I stopped dusting with calcium d3 and started to take them outside as often as possible. I just wanted to get some opinions on exposing your chameleon to pure sunlight in comparison to dusting with D3. I usually take my chameleon outside as often as possible but some times the weather is bad. How often is it necessary to expose your chameleon to the sunlight when you do not dust with D3? Also can it be harmful to stop dusting with D3 a couple days before you start the sunlight exposure?
