If the female does not have an appropriate nesting area or appropriate humidity, she might retain eggs. In their native environment, iguanas rest at night and begin the hunt for tender shoots, flowers, and soft fruits after basking in the sun for a few hours in the morning. After eating they bask in sun again to stay warm enough to digest food. Be sure to provide your iguana with a source of ultraviolet light and the appropriate amount of heat. Keep a thermometer available to monitor the temperature.
Iguanas are prey species, so a great part of the day is spent keeping a look out for predators.
Initially, you will be the predator it is protecting itself from. Socializing your iguana is a time-consuming process but necessary to ensure your pet's longevity. Many people end up getting rid of their iguana when it expresses its natural behavior of aggressiveness towards the predator, us. However, with time and socialization with you, your iguana will relax and be a happy safe pet. Remember, most health problems in reptile pets are related to inappropriate diet, environment, and husbandry.
