#1 iguanas do not eat meat, they need a very wide and varied diet of dark leafy greens and fruits and veggies. Also they need a small amount of calcium added to their food daily...I use a spoon nd scrape a cuttle bone onto my iguana's food daily. Cuttle bones are usually for birds. # 2 they need proper lighting and heat lamps to assure they won't get metabolic bone disease which is very common with iggys. A full spectrum light will simulate sunshine which in their natural habitat helps bone growth etc. Here's a good site about iguanas...and I should add, they aren't easy to care for by any means. http://www.greenigsociety.org/home.html
