What kind of plants iguanas eat?

Iguanas are primarily herbivorous and thrive on a diet of leafy greens, fruits, and vegetables. They particularly enjoy dark, leafy greens like collard greens, dandelion greens, and kale, as well as fruits such as mango and papaya. It's important to avoid feeding them foods high in calcium oxalate, like spinach and rhubarb, as these can inhibit calcium absorption. A varied diet helps ensure they receive the necessary nutrients for their health.
