If you have come here with a certain food in mind you can use the table of contents to skip to the section you need.
What do iguanas eat in the wild?
Iguanas are predominantly herbivores and eat vegetables, leaves and fruits. In Panama, the wild green iguanas favourite food is known to be wild plums. They consume a variety of plants and flowers, as they require exactly a 2 to 1 calcium to phosphorus ratio within their diet. Wild iguanas have been seen eating snails and insects like grasshoppers and some marine iguanas will dive down to eat algae!
What should pet iguanas eat?
You need to include a variety of greens, vegetables and fruits in your pets diet in order to keep them well balanced and healthy. They need to keep a balance of 2 to 1 calcium and phosphorus. They are omnivorous when they are younger but shift to almost 100% herbivores as they grow older.
They enjoy vegetables such as bell peppers, beetroot and carrots. Specifically red, yellow and orange vegetables should be the focus of their diet. Vegetables should only make up about 20% of their diet and fruits should make up 10%, while the rest of their diet should consist of leaves and flowers.
It is also easiest to feed them pellets which will provide the nutrition they require. There are multiple incredible brands that you can purchase at your local pet store, however pellets should only make up 10% of your iguanas diet.
What you should feed to baby iguanas.
Baby iguanas eat some insects and should be fed more regularly than older iguanas. They should be fed lots of dark leafy vegetables and other yellow, red and orange vegetables.
It is best to avoid vegetables like iceberg lettuce, as it has little nutritional value. Pellets can also be included in their diet, but should not make up more than 10% of their total diet. They should be fed twice a day and calcium and vitamin D supplements should be included in their diet to ensure that they have a completely balanced lifestyle.
A lack of calcium can cause severe harm to your baby iguana and especially while they are still developing.
What to feed an adult iguana?
Older iguanas appetites can vary, but on average they eat about once per day. It is best to avoid lots of fibre and rather focus on feeding them lots of green and leafy vegetables.
You can also incorporate pellets into their diets and add in yellow, orange and red vegetables. Your pet will also enjoy eating fruits, and they can be fed fruits as an extra treat. They are known to enjoy apples, grapes and bananas.
It is best to avoid feeding them lettuce as it has very little nutritional value. Very occasionally you can add grains to add some variety to their diet. It is also best to focus on fresh food and not frozen food.
Which insects should you feed your iguana?
Adult iguanas don’t require a lot of protein within their diets and regularly feeding them insects can be quite harmful to them. They are predominantly herbivores but very occasionally might eat a snail.
If you do wish to feed them one, please ensure it is not one you found in your garden and rather go and buy snails at a pet store. Wild snails may be contaminated with pesticides and parasites and this can harm your iguana.
However a word of caution should be included, as feeding your iguana insects will put a strain on their kidneys and livers and can cause them to become quite ill and even die.
Like juvenile iguanas, adult iguanas require calcium and vitamin D supplements in order to thrive and function as a healthy pet.
Where to get food for your iguana.
You can purchase pellets from any pet store and some supermarkets may also carry iguana pellets. Ensure that you purchase pellets specifically designed to nourish your little friend.
Of course you can also purchase all the fruits and vegetables they would normally eat at a grocery store or farmers market. You can also find dandelion greens and other fresh flowers that they may enjoy eating, at supermarkets.
It is best to always feed them fresh food and not anything frozen,as fresh food has a higher nutritional content.
How to keep and store food for your iguana.
Storing food for your little pet is quite simple. To make it easier, you can chop up all your fruits, vegetables and leafy greens and keep them in containers in the fridge to make daily feedings easier to administer.
If you keep some insects for your baby iguana, then you need to store them in a sturdy plastic container. Do keep in mind that you won’t need to store too many insects, as baby iguanas shouldn’t eat a lot of insects and adult iguanas shouldn’t really eat insects at all.
