What do herbivorous reptiles eat?

Tortoises, Green iguana, Uromastyx lizards, Chuckwallas and Prehensile-tail Skinks are among the herbivorous reptiles kept as pets. Healthy herbivorous reptiles consume about 15% to 35% of ME from protein, less than 10% from fat, and more than 50% from carbohydrate. Crude fiber intakes range from about 15% to 40% of dry matter (DM).
