Over the last 20 years, iguanas have become popular pets in the U.S., and juveniles can be purchased in many pet stores for less than $20. However, what most people fail to realize is the animals, when cared for properly, can get very large and live a long time.

Males are usually larger than females and can become aggressive, especially during mating season. Due to their behaviors, size and specialized care requirements, iguanas should not be your first reptile and there are much better choices for reptile fans. Consider an easy to care for gecko or bearded dragon.

To be happy and healthy, an iguana needs specialized care, including a strictly vegetarian diet with lots of dark leafy greens, fruit, vegetables and legumes, UV broad spectrum lighting, which simulates natural sunlight and enough space to stretch out, climb and grow to their maximum size.

Before you bring home any pet, understand what kind of care they need and be prepared for their adult size so you can accommodate them as they grow.
