Before you bring your pet home
The best possible suggestion I can offer is to have someone who is experienced with Iguanas go shopping with you when you are ready to buy it. But before you get it home you will have to have the temporary living quarters set up for your iguana. This will only be for your pet while it is a juvenile. I also highly recommend you get and house only one iguana at a time. Housing several iguanas together can pose some stressing situations to the other dwellers being housed, and cause severe results, such as malnutrition, molting or even death.
