The iguana is a cold blooded reptile. Some live in desserts and some live in rain forests. They live in trees near water. The iguana is a pretty inactive reptile, lounging around most of the time, but they can run quite fast when they want to. There long, sharp fingernails make it able from them to climb very well. They can grow to be 6-8 feet in length. The iguana has a long whip-like tail that it will use to lash out at an enemy (stings an awful lot).
An iguanas diet is made up of plants, fruits and vegetables. They do not eat live prey. That makes it a desirable exotic pet for some people who do not like the idea of feeding their pet live food. Iguanas lay eggs and in about 2.5 to 3 months baby iguanas will be born. Many of them will not survive and will become prey for larger lizards and other animals.
Having an Iguana
Having an iguana takes a very big commitment. Please make sure that you are thoroughly prepared and have all the information out there before, not after, you purchase one.
You will have to have a very large enclosure and your iguana can grow to be over 6 feet in length. You will also need appropriate lighting and heat. Their nails can be very sharp and you will need to be trimmed. They can be trained with allot of attention and I have heard that they can be litter trained as well. You need to be aware that like all lizards, iguanas have salmonella in their feces. You will have to take extra care in cleaning any areas that the lizard has been, washing your hands after ever encounter and informing people who come to your home that you have an iguana, about salmonella and what they will need to do while visiting you to protect themselves. My nephew has 3 and they are great. I love to play with them and hold them, but I keep my young children away.
There is so much information that I will leave the rest to the wonderful links below. Please check them out before you end up a situation that you can not handle that will lead to you being unhappy and the iguana being unhappy.
