My pet iguana was tiny and now it's more than 3 feet (0.91 meters) long! What happened?

If cared for properly, green iguanas can live more than 20 years. But they do indeed grow … grow … and grow along the way. Although iguanas make popular pets, they need lots of time, attention, care, and room to grow. A healthy iguana will grow to be 5 to 6 feet (1.5 to 1.8 meters) in length, and will require a very large cage or an entire room to live in. Iguanas need tall cages because they are tree-dwelling (arboreal) creatures, and prefer to spend the majority of their time as high off the ground as possible. Iguanas also need a special diet, plenty of sun, places to climb, and human interaction and stimulation.
