Aggression in Iguanas

Iguanas can be very aggressive and they may lash their tails or bite if they feel threatened. Their mouths are full of sharp teeth, so a large iguana bite will require numerous stitches and leave a lifelong scar.

Male iguanas should never be housed together and should not be in the same area of the house, if possible. Sexual aggression between adult male iguanas (especially single adult males in household) and human females can become a problem. Iguanas that are extremely tame can appear to become enraged when a woman releases pheromones during her menstrual cycle. This can be a frightening experience, especially for someone not familiar with iguanas.

Even the most docile iguana can scratch. Pet owners should, therefore, keep their iguana's nails trimmed. A dog or cat nail trimmer or an electric nail-melting tool works well. Scratches should be disinfected immediately, and reptile owners should be sure to update their tetanus shots.

Pet iguanas are not the best choice for novice reptile owners. Leopard geckos, Bearded Dragons, and corn snakes, on the other hand, make excellent pets for beginners.

People who decide to purchase green iguanas should be aware that they are making a long-term commitment - and not just buying a disposable pet.
