Iguana's use their homes for more than just shelter. It is imperative that his home provides the necessary protection but also the right heat for his well being. Unlike the dog or other mammals, iguanas must have a well maintained climate in order to stay healthy.

This is due to the iguana's need for the wavelengths of the light within its home. They will use these wavelengths to aid in their metabolism as well as in their body chemistry.

If you consider where the iguana is from, you can see what his needs will be in the climate that you create for him. The extreme temperatures of that environment were also fairly humid. This combination is what his body is conditioned for and therefore must be replaced in the shelter you'll provide for him if he is to survive and be as healthy as he can be.

Without an environment that is conditioned for the right temperature and humidity, your iguana will become ill, it will suffer and it may even die because of this one simple factor.

What does he need, then? There are several key pieces of information to consider. We'll break them down for you right here.

Do you need lots of room? The iguana is so small, how can they even imagine needing so much room? No matter what you thought about his size or the room he needed, this is an important consideration.

First, they aren't small. In many cases, an iguana will grow up to six feet in length. That's a lot of iguana for you to provide shelter for. There is one misconception out there about this, though. Many think that if they limit the room that they provide to their iguana that they will be safely protecting it from getting extremely large. This is not true. He will continue to grow.

Iguanas start growing at a faster rate then they will down the road. But, he will grow his entire life.

Within your first year of owning him, your iguana will likely grow out of the 55 gallon aquarium that you bought it. For this consideration alone you should carefully decide on whether this is the right pet for you. Space is necessary for the animal.

The animal will need enough room to roam, not to just sit still. While they grow you can expand their habitat to make it larger to fit the iguana but you must take into consideration this often, as they will continue to grow throughout their lifetime, even as they are older.

The rule of thumb is that your iguana's habitat should be at least twice the length of the animal and it should be taller. The taller it is the better. The minimum size for a habitat is that of six feet. It is minimum because this animal is likely to continue to grow. Without enough room, he will suffer needlessly.

Without the right size cage, your pet will suffer. He may injury himself just moving around. He will be stressed, which can cause him to be less friendly to you. Those that limit the iguana's ability to move will cause his muscles to become weakened. If you don't have this type of room to provide to your pet, don't make his suffer at your expense. You should consider a pet that is smaller.

One way to know what the proper size of the habitat for your pet should be is to notice any injuries that he may have. Those that have been rubbing their noses on the glass or the doors will have burn marks or injuries there. You may see broken claws too which means he was likely scratching and looking for a way out.

In addition, these wounds are an indication that he or she is not getting enough exercise in climbing. This is especially true of an animal that has weakened muscles. Monitor the size of your iguana to the size of his cage.

Monitor the growth of your baby iguana. When you start to notice the he is about 1/3 of the length of his habitat, you'll want to consider replacing it with something larger. But, it may be more cost effective if you instead provide a large enough habitat for your iguana from the beginning.

Nevertheless, during the first months of his life, a large sized aquarium is big enough for his needs. But, he will outgrow this within that first year. In addition, realize that your iguana will be fully grown within two and a half to three years time! Make sure you are planning ahead for when that next need arises.
