Pet iguanas have specific dietary requirements to stay healthy. They are primarily herbivores and need a diet rich in leafy greens, vegetables, and fruits. A balanced diet for a pet iguana may include dark, leafy greens such as kale, collard greens, and mustard greens, along with vegetables like squash, bell peppers, and carrots. Fruits such as strawberries, mangoes, and blueberries can also be offered as treats. It is important to provide a variety of foods to ensure they receive all the necessary nutrients. Additionally, calcium and vitamin supplements may be recommended by a veterinarian to prevent nutritional deficiencies. Always ensure fresh water is available for your pet iguana.
