Believe me...I'm not here to pull your strings. I know at least some turtles can get vitamin D3 from the food they eat and supplement, but believe me when I tell you that iguanas are different. If you take the time to read through Miss Kaplan's website, which is full of helpful info, you will know why iguana is generally kept with UVB lighting. And believe me...I know all about heating with iguanas. If they don't get warm enough their gut microbes that break down the plant they eat will cease to function and as a result, they won't be able to digest their food. I believe everyone that kept reptiles are familiar with the important of heat since they are dependant upon the surrounding temperature to function properly.
