Green Iguana in captivity

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).citation | title = Green Iguana | work = Reptiles and Amphibians Fact Sheets | publisher = Smithsonian National Zoological Park | url =http://nationalzoo.si.edu/Animals/ReptilesAmphibians/Facts/FactSheets/Greeniguana.cfm | date= 2007 ] 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, and many die within a few years of acquisition.

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 six feet in length and weigh some 20 pounds.citation | last = Rosenfeld | first = Arthur | title = Exotic Pets | publisher = Simon & Schuster | location= New York | pages = 105 | date= 1989 | isbn = 067147654 ]

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 phosphous) in their diet.cite web | last = Kaplan | first = Melissa | date = April 19, 2007 | url = http://www.anapsid.org/iguana/igdiet.html | title = "'MK Diet' - The Short Version" | work = Melissa Kaplan's Herp Care Collection | publisher = [http://www.anapsid.org anapsid.org] | accessdate = 2007-06-27 ]

There is some debate as to whether captive green iguanas should be fed animal protein.cite book | last =De Vosjoli | first =Phillipe | coauthors = David Blair | title =The Green Iguana Manual | publisher =Advanced Vivarium Systems | date= 1992 | location =Escondido, California | isbn = 74886904040 ] 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.cite web | last = Britton | first = Adam | date = April 19, 2007 | url = http://www.anapsid.org/adambritton.html | title = Animal Protein and Claw Trimming" | work = Melissa Kaplan's Herp Care Collection | publisher = [http://www.anapsid.org anapsid.org] | accessdate = 2007-06-27 ] 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.

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.cite web | last = Kaplan | first = Melissa | date = April 19, 2007 | url = http://www.anapsid.org/mbd.html | title = "Identification and treatment of metabolic bone disease" | work = Melissa Kaplan's Herp Care Collection | publisher = [http://www.anapsid.org anapsid.org] | accessdate = 2007-06-27 ]

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.citation | last = Blood | first = Michael R | title = Exotic Pets' Days Numbered | newspaper = New York Daily News | date= 6/30/1999 ] cite web | url = http://members2.boardhost.com/gisadoptions | title = "Green Iguana Society Adoption Board" (discussion board) | publisher = [http://www.boardhost.com/ Boardhost.com] | accessdate = 2007-06-27 ] 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.Citation | title = Iguana & Illegal Lizard Turned In Under Amnesty | publisher = State of Hawaii Department of Agriculture | date= 04/16/2002 |url=http://www.hawaiiag.org/hdoa/newsrelease/02-08.htm ]

Green iguanas are considered an invasive species in South Florida and along the gulf coast of Florida from Key West to Pinellas County.Citation | last = Krysko | first = Kenneth L | last2 = Enge | first2 = Kevin M | last3 = Donlan | first3 = Ellen M | last4 = Seitz | first4 = Jason C | title = Distribution, Natural History, and Impacts of the Introduced Green Iguana in Florida | journal = Iguana: Conservation, Natural History, and Husbandry of Reptiles | publisher = International Reptile Conservation Foundation | volume = 14 | issue = 3 | year = 2007 |pages=142-151 ] Over the years escaped and intentionally released iguanas from the pet trade survived and then thrived in their new habitat.Citation | last =Lush | first =Tamara | title = Florida's Iguana Infestation | newspaper =St Petersburg Times | date= July 26,2005 | year =2005 | url = http://www.sptimes.com/2005/07/26/State/Florida_s_iguana_infe.shtml ] They commonly hide in the attics of houses and on beaches and destroy gardens and landscaping.Citation | last =Youth | first =Howard | title = Florida's Creeping Crawlers | journal =Zoogoer | volume =20 | issue =3 | year =2005 | url = http://nationalzoo.si.edu/Publications/ZooGoer/2005/3/reptilefeature.cfm ] As most reptiles carry salmonella, this is also a concern and a reason legislation has been sought to regulate the trade in iguanas.

Socialization and habitat

Socialization of an iguana may take several years.cite web | last = McLeod | first = Lianne | url = http://exoticpets.about.com/cs/iguanas/a/iguanahandling.htm | title = "What to Expect with a New Iguana" | work = Handling Pet Iguanas | publisher = About.com | accessdate = 2007-06-27 ] 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.cite web | last = Lizardlover | first = Henry | authorlink = Henry Lizardlover | year = 1992 | url = http://www.todaysplanet.com/pg/beta/lizardlover/page19.htm | title = "Into the Iguana; Potential Behavior & Attitudes of the Iguana" | work = Iguana Owner's Manual | publisher = TodaysPlanet.com | accessdate = 2007-06-27 ]

As pets

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 and brief yet constant interaction with their owner. Unlike dogs and cats, Green iguanas do not like to be picked up, petted, or handled for extended periods of time as they are creatures of familiarity that will often get stressed when exposed to unfamiliar stimuli.

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).cite web | last = Eguro | first = Marie | authorlink = Marie Eguro | url = http://marie.thoughtshop.net/sammy_j/toiletTrain.html | title = "How to Toilet Train Iguanas" | publisher = ThoughtShop Networks | accessdate = 2007-06-27 ]

Most veterinarians do not have the training to treat an iguana.cite web | url = http://www.iguanaden.org/health/index.htm | title = "Iguana Health" | work = [http://www.iguanaden.org The Iguana Den] | accessdate = 2007-06-27 ]
