Iguanas do not drink from a pool or dish of water like normal animals. Instead, they lap up water from the sides of the enclosure and from rocks. So it is important to mist the aquarium two to three times a day. This will also create a humid environment for these animals, which keeps the skin of the iguana from drying out. Most people can agree on the idea that iguanas are vegetarians.
Most people feed a classic diet of fresh raw fruits and vegetables.
You want to be sure to avoid spinach because it can hinder calcium absorption. Some people supplement the diet with calcium-rich and protein sources such as dry dog food, scrambled eggs, and cooked chicken. It is best to check with a herpetologist or reptile veterinarian. Specially-formulated diet supplements can be purchased at the pet store and are often a good idea, especially ones that provide extra calcium. A dietary supplement such as Rep-Cal, which you can sprinkle on food, provides the iguana with extra calcium and vitamins.
