How often should a green iguana be fed vegetables?

Feed a green iguana vegetables 1-2 times daily in moderate amounts, with variety rather than the same kind. Safe choices include Indian lettuce, bok choy, kale, pumpkin, sweet-potato leaves, zucchini, lettuce, and carrot; avoid high-oxalate ones like spinach, rhubarb, beet, celery stems, cabbage, and broccoli. Young iguanas need more calcium and vitamins, so offer more vegetables but not excessively.
