NUTRITIONAL REQUIREMENTS:

Iguanas are herbivores and so require a good varied vegetarian diet, some outdated information crops up now and again mainly in old books, that says they can eat crickets, mice or cat & dog food, thankfully this information now tends to be disappearing fast, all experts are now in agreement on the herbivore status.
The diet below gives a good example of foods that can be offered and doesn’t need to be adhered to 100% but is supplied for guidance purposes, I find in winter time when fresh food can be scarce, a good substitute is the pre-packed mixed bags of salad greens available in all supermarkets, try to avoid the ones containing lettuce which is practically water and nil nutrition, these can be further supplemented with dandelion leaves.


DIET: Feed up to 50% of,
Leafy greens, Collards, Mustard greens, Turnip greens, Nasturtiums (leaves & flowers), Dandelions (leaves & flowers), Escarole, Rocket, Hibiscus leaves and flowers, Watercress, Land cress, fresh Alfalfa and Carrot tops.

Green beans, Zucchini, Squash, Bean sprouts, Okra, Parsley, Grated carrot Red Yellow or Green bell peppers (Sweet peppers), Leeks, Peas, Cucurbits, Parsnips alfalfa pellets, Vine leaves, Chinese greens and Celery.

The following contain "Oxalates" which binds with calcium and hampers absorption, and should not be fed in large quantities, Chard, Spinach, Rhubarb stems only (beware rhubarb leaves are very toxic), Dock, Sorrel, Beets and Beet greens.
