Picture of Basic Care Instructions for the Green Iguana
Reptiles are rapidly growing more popular as pets, and iguanas are no exception.  However, how to care for iguanas is not common knowledge.  Many iguanas are improperly cared for, and end up dying early.  Many people just do not realize how difficult and time consuming it can be to take care of these lizards.  These instructions will go over some of the basic care owners must give their iguana. The three main topics that will be covered are: habitat, feeding/ diet, and general care.  Included in the diet section is a basic iguana salad recipe.  Caring for these creatures can be a daunting task.  Taking the time to do some research on them, and setting aside time in your daily life is a good place to start.

Step 1: Materials Needed

You need to make sure you have these materials available before you start getting ready for your iguana.

- Cage which is preferably 4x3x5 ft. (length x width x height) or larger.
- Reptile heat lamps (day light, and a blue night light)
- UV light which provides at least 7 watts per cubic foot of UV radiation
- Newspaper
- shelving or branches
- Spray bottle or humidifier
- Nail clippers
- Tub or a bath
- Plants (real or fake) to decorate habitat
- Water bowl
- wash rag

Materials needed for iguana salad:

- Food processor
- 1 quart freezer bags (20 should do)
- B1 vitamin
- food plate or bowl
- The following fruits and vegetables: 1 mango, 1 cantelope, 1 sweet potato, 4 yellow squash, 1.5 cups of green beans, 2 parsnips, 2 carrots, 1 cup dry alfalfa pellets, 1 bunch of collard greens

Step 2: Setting up the habitat

Having the proper habitat for your iguana is very important.  Iguanas living in improper setups are likely to get sick or die early.  Besides keeping the temps and humidity at the right levels in the cage you should also think about decorating the cage.  Iguanas do not simply stop growing when they're habitat (cage) becomes too small.  It is okay to start with a baby iguana in a 40 or 50 gallon aquarium, but eventually a larger enclosure will need to be built for it.  Here are some steps for setting up your iguana habitat.

1. Make sure cage holds heat and moisture well (you should maintain a relative humidity above 40% in the cage). If sides or top of cage consist of wire or other open material, covering them with a plastic shower curtain will help.  Using Plastic sides (such as plexiglass) for your habitat is recommended in order to keep heat and humidity at correct levels.  
NOTE: I HAVE REPLACED THE WALLS OF MY HABITAT WITH CLEAR PLEXIGLASS

2. Pick out a basking area in the cage where you will build a shelf or place a branch

3. repeat step 2 except for a sleep area this time

4 Place day heat lamp above basking area. Turn lamp on and check to see that area is between 90-95 degrees Farenheit
CAUTION: Be sure the iguana will not be able to reach his lamps, they will burn themselves

5. Place blue night heat lamp above the sleep area. Turn on lamp and check to see that the temperature is between 74-78 degrees Farenheit

6. Set up you UV light making sure the basking spot receives direct rays, your iguana will spend most of its time on its basking spot

7. Use newspaper in the bottom of the cage (This is where your iguana will do his business)

8. Use decorations like fake plants and vines around the cage to make your iguana feel more at home (real plants can also be used, but make sure they won't harm your iguana if eaten)

Step 3: Feeding/Diet

Iguanas are strictly herbivores and have a very unique diet. Feeding your iguana the right diet will help him live a long and healthy life. Here are the main components of an iguanas diet, as well as the basics for feeding your iguana.

1. Your iguana diet should include: 45% greens, 40% other vegetables, 10% fruit, and 5% supplemental protein. You can check this Green Iguana Society website (http://www.greenigsociety.org/foodchart.htm) for a detailed list of acceptable greens, fruits, vegetables, and proteins.

2. Wash greens thoroughly. Wash and peel fruits and vegetables.

2. Vegetables and fruits should be cut up into pieces no wider than the iguanas head

3. Then vegetables, fruits, and proteins should be mixed in with the greens on a plate or bowl.

4. Offer the salad to your iguana. Some iguanas may take a while to get used to their new salad, usually within a week they will be chowing down your salad

Step 4: Basic Iguana Salad Recipe

This basic salad recipe includes all of the main components of the iguanas diet. Many iguana owners prepare fresh salads every day which can be time consuming. This recipe will save you lots of time because it can be frozen, and kept for a month and a half.

1. Have the following greens, fruits, vegetables, and protein supplement: 2 parsnips, 2 carrots, 1 sweet potato, 2 cups of green beans, 3-4 small yellow squash, 1 mango, 1 cantelope, 1/2 cup of dry alfalfa pellets, and 1 bunch of collard greens.

2. Wash and peel fruits and vegetables, wash collard greens.

3 Cut up fruits and vegetables into pieces that will fit into the food processor.

4. Run fruits and vegetables through the food processor. Afterward pieces of the fruits and vegetables should be the size of grated cheese.

5. Mix alfalfa pellets in with shredded fruits and vegetables. Make sure to mix salad thoroughly.

6. Put salad mix into freezer bags, around 3/4 cup of salad mix for each freezer bag

7. Set aside one bag of salad mix to be used within the next few days. The rest of the mix can go in the freezer.

8. Cut up 1-2 collard green leaves. Leaves should be cut into 1.5x1.5 inch cubes, discard the stem.

9. Place leaves onto a plate or bowl.

10. Put 1/4 cup of salad mix on top of your leaves. Then mix the salad and leaves together. If the salad has been frozen add a pinch of vitamin B1 powder (mix the powder into the salad)

11. Offer the salad to your iguana

Step 5: Basic Care

There are several ways you should care for your iguana on a day to day basis. You are completely responsible for your iguana, your iguana is not in the wild and cannot take care of itself.  Failing to keep your iguana and his cage clean can result in infections, parasites, and a lethargic iguana.

1. Use your spray bottle to spray water inside iguanas cage (keep relative humidity above 40%), you may need to use the spray bottle several times each day.  Could also use humidifier to keep humidity up.

2. Clip iguanas nails with nail clipper, usually every week.

3. Bathe iguana at least once a week in a large tote or bath tub depending on the size of the iguana (baths should last from 15-30 minutes)

5. Keeping a clean cage is essential. Make sure to wipe down shelves and floor daily

4. Fecal matter should be cleaned up within a few hours time.

I also add Brewer's Yeast to their food. It is a powder and it has an excellent vitamin B complex, and it is in the form of a food not an extract, so it is easier on their stomach. It really helps to bring out their colors! I started doing this with my first iguana and every him who saw him commented on how vibrant the colors were. It's inexpensive and very good for them.

Please advise that you need a UVB light, not just any old UV light ;)

You should try to avoid metal mesh for the cages. Plastic is far superior.  The metal can cut them and actually rip out nails.  PVC, plastic, and lots of zip-ties make a great cage for your herp.  Other than that, good job.

Also....purchase a "scissor-style" nail clipper for you ig....the normal style for humans doesn't really slice but more of squeezes. This causes the nail to crack and can cause more bleeding.  You can pick up the scissor style for only a few bucks at a pet store and since they have finger holes, its easier to clip the nails without worrying about dropping the clippers.

 Yea I have the scissor clippers too, couldn't find them when i took the picture.  Plastic is definitely better for a cage, like you said they are less likely to get hurt and the plastic will keep in heat and humidity.  However I"m a full time college student at ISU and didn't have the money or the time to go this route.  Thanks for your comments though.

 Here is a (mess) shot of the cage I had built for my ig a few years back.  I used the lid from a storage bin as a pull out litter box and had a swinging door made from pvc.  The rope was just my quick solution to hold up the sides I made.  I realized that I was losing too much humidity and heat so I went out and purchased a thick vinyl shower curtain, some spline, and the frame for making screens.  I used a hacksaw to cut the screen frames to length, used the connectors to make connect them into a frame, then I used the spline to make vinyl "walls" that worked very well.  In total this cage only took about a day to make.  I gave it away though with my iguana before I left for school.  Good luck with your ig!

Nice, I thought Iguana to be omnivorous, what is the B-vitamin a substitute for w/ref natural diet?

bamoser (author)  lemonie5 years ago
In the wild juvenile iguanas are known to eat insects from time to time, but animal protein is very hard on their kidneys and can cause death eventually.  Heres a link to an interesting article about this: http://www.anapsid.org/iguana/animalprotein.html

Interesting link Does the B-vitamin replace some minor but essential natural food source?

bamoser (author)  lemonie5 years ago
The natural B1-vitamins leach out of vegetables during freezing so they need to be added back in before feeding.  Iguanas need the B1-vitamin to help them in digesting their food.
