Hi Billbob, first of all kale, cabbage, broccoli and cauliflower are no nos for green iguanas. They cannot eat anything from the cabbage family. Try dandilion greens or collards.. although my iguana is 21 and he doesn't like collard greens. Whatever greens you offer him, try adding some raspberries or chunks of oranges or some kind of fruit as they will often eat the fruit first. Once he starts eating he might continue on with the greens. I buy mixed frozen veggies and steam them and put them over his greens. THe best greens are endive which is usually hard to find. I also feed green peppers, blue berries, grapes and if you don't have any fruit just sprinkle some juice over the food like 5 Alive. or apple juice. Hope this helps..
