Thank you for your question. Iguanas are strict herbivores and should not be fed meat. A well-balanced iguana diet will consist of about 40-45% greens, 40-45% other vegetables, 10% or less of fruits, and less than 5% of other grains or commercial diets. They should be provided a multi-vitamin supplement and a calcium supplement based on your iguana's age and health status. One of the most important factors in providing a well balanced diet is maintaining a calcium to phosphorus (Ca:P) ratio of about 2 to 1. This is critical in order for the bones to properly grow and remain strong.
