Green Iguana



Green iguanas (Iguana iguana) are some of the larger examples of the pet reptile world, found from Mexico and Central America down through South America. Adult males may reach 7’ in length, weighing up to 20 pounds. The sheer size is a preliminary obstacle that discourages most beginners from becoming green iguana owners. Green iguanas are both arboreal and terrestrial. The enclosure for one adult (two males cannot be housed together) should be twice as long and as wide as the iguana itself. Cage minimums for adults are 12’x6’x6’ high, with sturdy mesh fencing around and over the top, or appropriate other caging allowing appropriate ventilation and thermogradient. Smaller cages may be necessary for babies growing, as large pens make it more difficult to find food. Temperature issues are also more complicated with the larger pens, and humidity and moisture challenges exist as well. Nutrition has specific requirements in terms of “do’s” and “do not’s.” UVA and UVB lighting are required, and heat must come from above as iguanas are basking species. If the herper is experienced enough to create good habitat conditions, while meeting nutrition, health and care requirements, then green iguanas can make good pets for many years. With their individual personalities, ability to recognize their keepers and potential to seemingly show affection, they can reward their owners.
