How to buy an iguana
Consider whether this is the right pet for you.
Iguanas as pets aren't for everyone. You need to know that they get up to 4 feet and some grow as much as between 5 to 6 feet long and have been known to get a little larger.
They can overpower small adults and can seriously injure you if you're not careful. They have a very strong bite, and a very strong tail which they use to whip.
