The Green Iguana (Iguana iguana) has become popular in the pet trade - over 800,000 animals were imported into the United States alone during 1995, primarily originating from captive farming operations based in their native countries (Honduras, El Salvador, Colombia, and Panama). They can live to be 20 years old. In 1998 a National Iguana Awareness Day (NIAD) was established to discourage consumers from viewing iguanas as "disposable pets". Despite the low cost and "mass market" appeal of these animals they are demanding to care for properly over the course of their lifetimes. More often than not, diet, lighting, and other housing conditions for green iguana are inadequate (in a major way) causing 70% of green iguanas in captivity to die within their first year of life.

Size
People purchase iguanas due to the small size, low price, and apparent low cost of feeding of juvenile iguanas. Though small as juveniles, iguanas can grow to 6 feet in length and weigh some 20 pounds. An iguana will not grow properly without a UVB light source. The UVB is necessary because captive iguanas do not get natural sunlight and this UVB allows the iguana make vitamin D3. The purpose of vitamin D3 is to digest calcium. Without being able to digest calcium, the iguana develops Metabolic Bone Disease (MBD). Metabolic Bone Disease causes soft bones, stunted growth, permanent bone deformities, frequent broken bones, loss of limbs and ultimately, death.

Diet
Although they will consume a wide variety of foods if offered, green iguanas are naturally herbivorous and require a precise ratio of minerals (2 to 1 calcium to phosphorus) in their diet. The best food source for the Iguana is dark green leafy greens such as collard greens, turnip greens, dandelion greens and small portions of kale, which is too high in phosphorus for everyday use. Hibiscus flowers and dandelions may also be added. The diet needs to be a greater percentage of dark greens, moderate amount of squash, and less of fruits. Some of the most accessible staple vegetables, greens, and fruit are collard greens, Turnip Greens, Kale, Parsnip, Butternut squash, Tomato, Mango, Blueberries, Watermelon, and an occasional Apple or Banana slice and Watercress as a treat. Also of concern is the oxalate to calcium ratio, and avoiding those that provide too much oxalate which is harmful. Foods high in oxalate should not be given for an everyday diet are: Broccoli, Carrots, Snap peas, Okra, Sweet Potato, and Romaine lettuce. An Iguana should never be fed Iceberg lettuce or Spinach.
There is some debate as to whether captive green iguanas should be fed animal protein. Zoologists, such as Adam Britton, believe that such a diet containing protein is unhealthy for the animal's digestive system resulting in severe long-term health damage and death. On the other side of the argument is that Green iguanas at the Miami Seaquarium in Key Biscayne, Florida, have been observed eating dead fish and individuals kept in captivity have been known to eat mice without any ill effects. De Vosjoli also writes that some animals have been known to survive and thrive on eating nothing but whole rodent block, or monkey chow, and one instance of Romaine lettuce with vitamin and calcium supplements. However, just because an Iguana will eat certain foods it does not mean this is what's best for it. A protein or lettuce diet will greatly shorten the Iguana's life and for this reason should be avoided.
Heat and light
Being tropical animals, Green iguanas will thrive only in temperatures of 75 to 95 degrees Fahrenheit (24 to 32 degrees Celsius) They require a source of Ultraviolet (UVA and UVB) lighting; without proper lighting their bodies cannot develop Vitamin D, and subsequently will develop metabolic bone disease which is fatal if not treated.
Legalities
In some locales, iguanas are considered exotic pets, and may be prohibited (New York City and Hawaii), or a special license or permit may be needed to own an iguana. Hawaii has strict regulations regarding the import and possession of Green iguanas, violators can spend three years in jail and fined up to $200,000.
Green iguanas are considered an invasive species in South Florida and along the gulf coast of Florida from Key West to Pinellas County. Over the years escaped and intentionally released iguanas from the pet trade survived and then thrived in their new habitat. They commonly hide in the attics of houses and on beaches and destroy gardens and landscaping. As reptiles can carry salmonella and other bacteria, combined with destruction of fragile native threatened and endangered species and habitats in the unique environment of the Florida Keys, many advocate for legislation to regulate the trade in iguanas and advocate their eradication in the wild.
Socialization and habitat
Socialization of an iguana may take several years. Iguanas have individual personalities that require some adaptation on the part of the owner. At about five to ten years, an iguana may exhibit bonding behavior similar to that of mammalian pets. Such an iguana may have a complex "need of attachment" to include separation anxiety.
As pets
Green iguanas are not suitable lizards for beginners. A pet iguana habituates to humans to such a degree that humans no longer cause a "fight or flight" reaction. Iguanas achieve this after they have acclimated to their new habitat, as well as brief but constant interaction with their owner. Fiji banded iguanas are a better iguanid option for less-experienced pet owners because they are smaller and less aggressive; however, they still need specialist care.
Healthy pet iguanas are very observant, confident, and curious. Iguanas can be "potty-trained" to go outside (when it is warm), go in a specific location (as on newspaper) or in a tub of warm water (and even on the toilet).
Most veterinarians do not have the training to treat an iguana, making treatment difficult to procure, expensive, or both.
