Healthy Feeding Guide For Your Iguana

healthy feeding guide for your iguana

So, what does iguana eat (and, also important – what doesn’t)? Below is a complete information that refers to the healthy feeding guide for your iguana. Most of these foods need to be given occasionally but also moderately and no overfeeding (I think we can’t stress this enough).


First, for visual types, we’ll repeat our iguana diet infographic:

Feel free to share this Infographic on your site!

Overall iguana diet should fulfill this condition: Calcium to Phosphorous ratio to be around 2:1

But, don’t forget that variety is also important. You can not just stick to one set of foods and feed the ig with it every day. Bad nutrition leads to many of common diseases of iguana which may be fatal for your pet (and certainly will cause pain an misery).

Note that main diet or basic food should be given in turn with different combinations with other fruit/vegetables. This is the crucial condition to have healthy iguana, which will grow to its full size. The information below makes it easy for you to know the super food to grow a healthy iguana. In order to make it easier to follow, we divided food into four groups:

STAPLE – A base diet for the iguana (but do not forget to variate with other super foods). In the table below you’ll find staple food labeled as ‘[1] STAPLE’, in order to allow easier sorting.

OCCASIONAL – Food that needs to be given moderately. Avoid overfeeding at all costs. It may cause severe health problems for your pet. Combine it with basic foods (several times a month) and make a balanced mix.

TREAT – This is good for iguana as a snack. Some of these foods fall into the usual diet but most of the food needs to be given occasionally.

COLOR ENHANCER & FLAVOR – Only occasionally added to a balanced diet to make the food served more delicious and appealing to the iguana’s taste.

Now, here comes the ‘ultimate’ iguana food table with more than 80 vegetables, fruits, greens. I didn’t want to clutter it with detailed nutrition values, except Ca:P ratio, since they will be mostly contained in the comment about how often iguana can be fed with. Remember that, if you can’t achieve optimal 2:1 ratio, you should apply Calcium supplement. As already stated, Ca:P ratio is NOT the only criteria whether the food is good or bad. Some foods are rich in oxalate which can cause bladder stone (spinach for example). Keep it various.

Click on column headers in order to sort them and get more readable data. For example, you can sort by Ca:P ratio to see the best foods according to this important factor. Click on the Comment label to sort foods by how often you can feed iguana.
