Their large size and strict husbandry requirements mean they need a lot of space and a lot of care, and it can be expensive and time-consuming to meet their needs. * iguanas grow to a mature size of 5-6 feet long. Accordingly, they need a large enclosure - as large as possible. This list is created to help Iguana Owners Buy the proper care Items they will need."
