While iguanas are fascinating and exotic pets, they can be dangerous when they feel threatened. Some might even consider iguanas dangerous due to their potential to cause harm. Iguana bites can result in significant damage and potential infections, transforming a seemingly docile creature into a force to be reckoned with.

The bite from an iguana, even an endangered species, may become infected if not treated adequately.

It is essential to clean a bitten area by a pet iguana with soap and water. This will reduce the risk of any infection developing. If the bite is severe, medical attention should be sought immediately. It is also recommended to take the entire course of antibiotics prescribed if an iguana bite, even from pet stores, displays signs of infection or swelling.
