Can iguanas eat apples?

Yes, iguanas can eat apples but in moderation. Apples are high in sugar so you don’t want to overdo it. Remove the seeds and peel of an apple before feeding it to iguanas. The fruit should be cut into smaller chunks. 

This will prevent the apple from becoming a choking hazard. Plus the seeds of apples contain cyanide which is toxic If ingested. Apples should only be given as a treat to iguanas. 

Only 15-20% of the energy intake of iguanas should come from treats like apples and other fruits. Giving the treats in moderation to iguanas will prevent obesity, diarrhea, and other issues in iguanas.

Foods to not feed a pet iguana 

Lettuce and Rhubarb: Lettuce leads to diarrhea in iguanas. Besides, It does not fulfill the nutritional needs of iguanas. 

Rhubarb is toxic for your pet iguanas. It can cause mineral buildup in the kidneys leading to kidney damage.

Spinach and Beet Tops: These two vegetables are rich in oxalates which have the capacity to bind calcium and reduce its absorption. In iguanas, this can lead to Metabolic Bone Disease (MBD) which gives rise to other health conditions in iguanas.

What type of plant material can I feed my iguana?

Vegetables are iceberg or head lettuce and celery are considered nutrient-poor and should be avoided. Feeding Calcium-rich vegetables to iguanas is encouraged. 

These vegetables include collard greens, beet greens, mustard greens, turnip greens, alfalfa hay, bok choy, kale, parsley, Swiss chard, romaine, kohlrabi, escarole, and dandelion.

Vegetables like Swiss chard, spinach, and beet greens are notorious for making your iguanas nutrient-deficient because they bind with the calcium rendering them un-useful for the iguana. 

Similarly, vegetables like cabbage, kale, and mustard greens contain goitrogens that can lead to goiter and hypothyroidism.

Do I need to give my iguana vitamin and mineral supplement?

It depends on the iguana’s age. Dietary needs for calcium and phosphorus are particularly high for all iguanas independent of their age. It is recommended to spray calcium powder on iguanas feed at the rate of 4-5 times every week. 

Use a specifically formulated calcium powder for reptiles (calcium carbonate or gluconate), that does not contain vitamin D or phosphorus.
