Melissa Kaplan at Herp Care Collection cautions that iguanas are not for everyone. They are, sadly, not for the too many people who get them only to turn around and dump them because they were completely unprepared for what iguana keeping involves.
If you aren't up to all the reading that needs to be done to learn to care for iguanas properly, then iguanas aren't for you. If you are not ready to acomodate all the intrusions keeping an iguana will make into your life (and finances), then iguanas aren't for you.
Iguanas are difficult, frustrating, complicated, complex--and potentially dangerous.
