Anyone know about iguanas?

he needs a diet better than just romaine lettuce, you can find some good diets on google. he will also need uv lighting and calcium, you can find many rich calcium foods on google or he will suffer from metabolic bone disease, this is pretty easy to spot just by looking. He will look like popeye, you know the big biceps then a thin leg....you get the idea I'm sure. Also he needs an enclosure bigger and safer then rubbermaid, they like to be up high so height is an important factor when consideing a cage. You don't say how big or how old he is so I cannot say what size he would need, but an adult can get huge so an enclosure to accomodate an adult size would be best. he will also need a basking light, NOT a heat rock, the heat will help his food to digest. It should cover a small area of his home so when he gets to hot he has a cooler area to move to.
