The iguana as a pet

The iguana is a reptile of the Iguanidae family found in Latin America and the Caribbean. It lives mostly in humid forests, where it prefers to live in the trees, since it is an excellent climber .

It is an oviparous animal , that is, it reproduces by means of eggs. Although its diet is mainly herbivorous, it varies in the different stages of its life, so we explain below what is most advisable for them according to their age.

Iguanas Food List: Editors Picks


What do baby iguanas eat?

The baby iguana needs to eat twice a day , always fresh and chopped very small or grated. The best advice is to let them sunbathe right after eating, because the rays help metabolize the ingested food and assimilate the nutrients.

95% of the baby iguana’s diet should be vegetables and green leaves , while only 5% should be fruits and special iguana feed. In this way, the basis of your diet should be constituted by:

  • Alfalfa
  • Zucchini
  • Coriander
  • Tomatoes
  • Apples
  • Papaya
  • pumpkin
  • Jewish
  • Pear
  • Cantaloupe
  • FIG

Similarly, avoid citrus fruits , such as orange, lemon and kiwi, as they are very acidic for the digestive system of iguanas. Foods such as carrots, lettuce, bananas and grapes are only offered occasionally, while Brussels sprouts, celery, beet and cauliflower are forbidden. Likewise, you should never give it meat , eggs or dairy products.

Baby iguanas can also eat iguana feed , preferably softened with a little water, but only once or twice a week. Do not forget that the variety of your diet is the key point to keep it healthy.

Some vitamin supplements of phosphorus, calcium and vitamin D can also be administered, but occasionally and always under the supervision of a veterinarian.

What do young iguanas eat?

As we already mentioned, the feeding of these reptiles varies according to their age. That is why, to be completely vegetarian when they are babies, as the iguanas go into the youth change their habits to eat not only fruits, plants and vegetables, but also some insects . Of course, as Albert Martinez and Joaquim Soler tell us in their book The Great Book of the 100 questions about reptiles [1] , this type of food should be offered very sporadically, since it is not ideal iguana food.

However, in captivity it is difficult to give live insects. You can offer some that you find in the garden, always of small size, in a proportion of once or twice a week. Avoid dry or flake foods such as those sold in pet stores, such as flies or mosquitoes, as it is usually recommended for fish and turtles.

Like the baby iguanas, the young eat a couple of times a day, although in greater quantity. How do you know the proper proportion of iguana food ? It will depend on each individual. An easy way to know is to offer the container with the food and, if it leaves food, it means that it is too much; this way you can determine the quantity, since they eat until they feel satiated.

What do adult and elderly iguanas eat?

When they reach the adult stage and for the rest of their life, including old age, the iguana is completely herbivorous . Vegetables, fruits and green leaves are all your food.

To be healthy, they need at least 40% of what they eat to provide them with calcium , such as tomatoes, zucchini, cucumber, parsley, strawberry, melon and pear. Iguanas special food is also recommended, but in proportions of maximum twice a week, so you can offer it as a reward. You can also give grains and cereals such as brown rice, once a week and in a proportion of only 5% of the iguana food you give.

As in the other stages, if you wonder what iguanas eat and what foods are prohibited, during adulthood and old age you should not give meat , dairy products, let alone recommended feed for other species, such as dogs, cats or rabbits. Remember that these types of products are formulated differently for each animal.

Some wild flowers may be recommended for iguanas, but only if you are sure they do not contain pesticides or other chemicals, and as an additional food supplement.

As you will suppose, the diet of iguanas in their natural habitat is similar to what you provide at home , after all, a healthy diet is one that best mimics the diet of the species in freedom; adding, of course, vitamin supplements when necessary.

In freedom, however, it is easier for young iguanas to eat insects. Occasionally, the black iguana can consume eggs of birds and even small mice, that is, if you wonder what the iguana feeds on you should know that it can also be carnivorous; however, protein does not form the basis of your diet.

In the nature the iguanas lie in the sun just after eating , this is a need that you must satisfy when you have one as a pet to ensure an adequate absorption of calcium.
