What do iguanas eat as pets?

What To Feed Your Iguana - Food List For Iguanas

As pets, iguanas need a strictly vegetarian diet, to live a long live and prevent issues with kidneys. So your iguana must only eat vegetables, greens, flowers and some fruits.

Your iguana must not eat any form of meat, insects, eggs, cheese, dog food and more. People used to give iguanas meat or bugs to make them grow bigger, especially at a younger age. Offering your iguana meat and bugs will cause kidney failure just after few years of this diet.

Any form of the protein that your iguana needs should come from vegetables. Iguanas also don’t drink much water – so they also get most of the moisture from the food. Dog or cat food to iguanas is dangerous – they are unbalanced in nutrients and high in protein!

How often do iguanas eat?

Iguanas eat 1-2 times a day, but some owners feed their iguanas only once in 2 days. The best practice is to feed your iguana its main meal in the morning, and offer some snacks later in the evening, 3 hours before the sleep, same time every day (iguanas love routines).

Iguana food chart

Your iguana must mainly eat leafy greens – you should offer them every day. Then, with less frequency, you can add other veggies and flowers.

Leafy greens should make up 50-60% of iguana’s diet. Then, 30-40% will contribute to vegetables and flowers. Fruits and berries should only contribute to 10% of your iguana’s diet.

Ca:P ratios, goitrogenic and oxalic foods in iguana’s diet

Please remember that Ca:P ratio is extremely important in iguana’s diet. The best greens, veggies and fruits should contain 2:1 Calcium to Phosphorus, or up to 2.5-3:1 Ca:P. Phosphorus ratio should never be higher than Calcium. If it is, you must mix them to reach the balance.

Even the multivitamins that you get must be balanced. Read everything about iguana supplementation in this post.

Foods also must not be high in oxalates (binding calcium) or goitrogenic (binding iodine).

Based on these factors, foods for iguanas are divided to staples, to occasional and rare consumption.

Each day, mix various staples, little bit of fruits and veggies to make a salad. Mix 4-5 types of greens (60%), 1-2 types of veggies (30%), and few pieces of fruits (10%). Don’t forget to alternate veggies, greens, flowers and fruits every day. This will provide varied nutrition.

Even if the fruit is in the staple food list, you must only offer 10% of fruits in iguana’s diet! Same goes to vegetables – 30-40%! Offer greens every day, and mix some staple or occasional veggies, fruits and flowers in the salads! Quantity and frequency is the key.

Please note that the diet for baby and adult iguanas should be the same. Make sure to start offering a variety of greens, veggies and fruits from the beginning. Otherwise, your iguana will become a picky eater.

Let your baby and juvenile iguana eat as much as it wants. But starting from the age of 4-5, reduce the portions a little to prevent obesity.
