Green Iguanas are native to Mexico, Central America, islands in the Caribbean, and South America. Free-ranging adults live in trees eating leaves and blossoms. Most pet iguanas are from “farms” in Central America and imported for the pet trade. Maximum life span is listed as 25 years, with average captive life span at least 7 years.
They can reach 5-6 feet in total length with the body weight of 15-18 pounds. They are sexually mature between 2-4 years of age. Adult males have a taller dorsal spine, larger dewlap, operculum scales, bilateral hemipenal bulges at the base of the tail, and large, well-developed femoral pores.
Many exhibit seasonal aggression once mature. Consult your veterinarian for behavioral and health management.
Iguana Care Sheet (includes red, green and blue iguanas)
Iguanas are 100% Herbivores. Leafy, Calcium-rich greens: This group should make up at least 70% to 80% of the diet: Collard, turnip, mustard and dandelion greens, chard, kale, parsley, etc.
Chopped grass, alfalfa hay or pellets can be offered: pellets may need to be soaked prior to feeding. Spinach fed in small quantities occasionally as it contains high concentrations of oxalates.
Almost any dark and leafy green is beneficial, but it is important to rotate them so as to avoid a build up of oxalates and phytates that will bind calcium, and also goitrogens that will bind iodine.
20% of the green iguanas diet should be composed of vegetables. Yellow, red or orange veggies are preferred. Choices include sweet potato, carrot, beet, squash, red bell pepper.
Less than 10% of iguana iguana diet should be composed of fruit. The fruit is very calcium poor and should only be fed on a limited basis. Choices include; melon, papaya, berries, banana, kiwi, apple.
Small amounts of low-fat non animal protein (ie. Mori Nu low fat Tofu) can be offered a couple of times a week but is not required. Additionally, we highly recommend edible flowers such as dandelion, nasturtium, hibiscus, pansy, etc. Flowers are part of the wild diet of green iguanas and are usually eaten readily. Iguanas seem to prefer red to purple colored flowers.
A basking area should be provided with a temperature of 90-95o F. A cooler area in the high 70’s to low 80’s should be provided allowing your iguana to regulate their body temperature by moving from one area to another.
Thermometers are necessary to ensure a proper temperature gradient. A “Temp Gun” can be used to read surface temperatures and is recommended.
Radiant heat sources (heat lamps) should be used as they provide a more natural and safer method of delivering heat than other sources. Heat rocks should never be used.
Ceramic heat emitter bulbs are preferred as they do not emit visible light and can be left on at night after the light producing basking bulbs have been switched off.
Iguana require a specific wavelength of light called UVB for their health. UVB is necessary for the proper absorption of calcium.
Green iguanas come from the rain forest where humidity is near 100%. In captivity, misting the iguana 2-3 times a day will help elevate the humidity.
A humidistat should be purchased to monitor the humidity in the cage. In some cases, a humidifier may be necessary to bolster humidity.
Freshwater should always be available in a water dish ideally one large enough for the iguana to submerge.
Many iguanas will defecate in their water bowls making for easy cleanup but also necessitating frequent cleaning and sanitizing of the bowl.
