Ultraviolet radiation is required for the synthesis of vitamin D3 which is essential for the absorption of calcium. It can also have an effect on behaviour and overall vigor. A large water pan should also be provided for drinking and soaking and as a means of raising humidity. This should be cleaned daily and fresh water provided. A fine misting of the enclosure will also help humidity.
Iguanas are mainly herbivorous.
Due to the rapid growth of a young iguana, a proper diet is very important. The following are various foods which, if offered in a variety, will provide a balanced diet - thawed mixed frozen vegetables, broccoli, brussel sprouts, grated carrot, dandelion greens and flowers, mustard greens, tofu, spinach, baked squash, sweet potatoes and a large variety of fruits. The foods should be cut up in bite sized pieces and offered fresh daily. There are also several good iguana foods available at selected pet stores. These may be added to the produce.
