Iguanas are among the most popular pet reptiles. They love to bask in the sun or under an ultraviolet light, and they enjoy a diet of leafy greens and vegetables. Many people don’t realize that iguanas can grow to be quite large, exceeding 6 ft (1.8 m) in length. Iguanas should be properly socialized when they are young to ensure that they can be handled as adults. They require specialized housing and regular veterinary care and may not be a suitable pet for everyone.
