Green iguanas are herbivores. Despite the popular belief that juvenile iguanas can be fed crickets as their primary food source, vegetables are the healthiest way to go.
There is a great deal of discussion amongst the reptile community as to whether or not pet iguanas should get animal protein in their diets but regardless of the arguments on either side, it is still best to stick with the dark leafy greens as the majority of your iguanas diet.
Also, remember to always offer a variety of vegetables to your iguana and rotate what you offer on a daily or weekly basis.
Veggies To Feed Regularly
Remember, the majority of the staple diet should be dark, leafy greens. Regular, but small amounts of fruits can be given alongside the greens and other things offered as treats as listed on the following page.
