Foods that harm Iguanas

Iguana Harmful

You should take great care in administering an iguana’s diet, failure to do so may result in them dying on you. Even if you provide your iguana green vegetables, you still have to check what they contain. If they are toxic to iguanas, you definitely have to avoid those greens.

Not all green vegetables can provide them all they need, but you should still be well educated on the foods iguanas can eat when you own them.

Can Iguanas Eat Meat?

No! Iguanas should not eat meat. They contain high protein. That meat will damage their kidneys and liver. They will get weak and it will shorten their lifespan. They will not grow normally, so it may stunt their growth and they will live unhappy lives. There are, however, a few insects that will not affect your iguana.

Can Iguanas Eat Kale and Spinach?

Yes, but should be given in small, controlled portions. Kale contains goitrogens. This will cause your iguana to suffer from a thyroid issue.

Spinach contains a high level of oxalate content. This means that iguanas cannot absorb calcium from other substances. This will lead your iguana to have Metabolic Bone Disease (MBD), and you need to consult your veterinarian.

Avoid Oxalic Acid in Your Iguanas Diet!

The vegetables you provide in your iguana’s regular diet may have some oxalic acid, but these do not harm your iguanas. Long-term consumption, however, will cause storage oxalates in kidneys and forms crystallized or mass forms. They also cause calcium deficiency.

Vegetables high in oxalic acid are spinach, rhubarb, celery, beetroot, chard, fried potato chips, parsley, and leeks.

Fruits that are high in oxalates are kiwi, figs, and small berries. These can be provided occasionally as a treat. But try to limit the proportion.

You should NEVER provide your iguana with goitrogenic foods, as they may cause thyroid issues like goiter.

Foods that contain high levels of goitrogens are mustard, cabbage, broccoli, Brussel sprouts, bok choy, kale, rutabaga. You may still provide these in controlled portions, but also provide iodized supplements.

Wash the Vegetables and Fruits Before You Provide Food

Never give provide food for your iguana without washing the vegetables, fruits, plants, or flowers first. This is because they have been sprayed with pesticides. If your iguana consumes pesticides, it may cause digestive problems.

Avoid giving your iguana garlic cloves, habanero peppers, and lemon juice mixtures – these don’t have the good taste to them and have foul smells. Your iguana will refuse to eat their food when it tastes sour.

Final thoughts
