Everything you need to know about Iguanas – The ultimate care guide

Iguanas are fascinating creatures that make great pets for those who are willing to provide the proper care and attention. They are intelligent, curious, and can even become quite affectionate with their owners. However, keeping an iguana as a pet requires a significant amount of effort, time, and money.

In this guide, we will cover everything you need to know about caring for an iguana, from choosing the right type of iguana to providing the proper habitat, diet, and healthcare.

Choosing the right iguana


Before you bring an iguana home, it’s important to choose the right type of iguana for your lifestyle and living situation. Here are some of the most common types of iguanas:

  • Green iguanas: These are the most common type of iguana and can grow up to 6 feet in length. They require a large enclosure and plenty of UVB lighting.
  • Rhinoceros iguanas: These iguanas are known for their unique horn-like protrusions on their snouts. They are smaller than green iguanas, but still require a large enclosure and UVB lighting.
  • Red iguanas: These iguanas have a red coloration and are slightly smaller than green iguanas. They also require a large enclosure and UVB lighting.
  • Blue iguanas: These iguanas have a blue coloration and are slightly smaller than green iguanas. They require a large enclosure and UVB lighting.

It’s important to research each type of iguana to determine which one is right for you. Consider the size of the enclosure you can provide, the amount of time you can dedicate to caring for your iguana, and the amount of money you are willing to spend on their care.



Iguanas require a large enclosure that provides plenty of space to move around and climb. Here are some guidelines to follow when setting up your iguana’s habitat:

  • Enclosure size: The enclosure should be at least twice the length of your iguana and tall enough to allow for climbing.
  • Lighting: Iguanas require UVB lighting to help them metabolize calcium and prevent metabolic bone disease. Make sure to purchase a high-quality UVB bulb and replace it every 6-12 months.
  • Temperature: The enclosure should have a basking spot with a temperature of 95-100°F and a cooler area with a temperature of 75-80°F. Use a thermometer to monitor the temperature and adjust the heating source as needed.
  • Substrate: Avoid using loose substrate like sand or wood chips, as iguanas can accidentally ingest it and cause impaction. Instead, use reptile carpet or paper towels as a substrate.
  • Climbing materials: Iguanas are arboreal and require plenty of climbing materials in their enclosure. Provide branches, logs, and shelves for your pet to climb on.
  • Humidity: Iguanas require a humidity level of 60-70%. Use a hygrometer to monitor the humidity and provide a water bowl for your iguana to soak in.



Iguanas are herbivores and require a diet that is high in fiber and calcium. Here are some guidelines to follow when feeding your iguana:

  • Vegetables: Offer a variety of dark leafy greens, such as collard greens, kale, and mustard greens. Avoid feeding your pet spinach, as it can bind to calcium and prevent absorption.
  • Fruits: Offer small amounts of fruit, such as strawberries, papaya, and mango, as a treat.
  • Supplements: Dust your iguana’s food with a calcium supplement powder to ensure they are getting enough calcium.
  • Water: Provide fresh, clean water in a shallow bowl at all times. They also enjoy soaking in water, so make sure to provide a larger bowl for them to soak in.

It’s important to note that they have specific dietary needs that must be met to prevent health issues like metabolic bone disease. Avoid feeding your iguana dog or cat food, as it does not provide the nutrients they need.


Iguanas require regular veterinary check-ups and care to ensure they remain healthy. Here are some healthcare tips to keep in mind:

  • Find a reptile veterinarian: Not all veterinarians are experienced with reptiles, so make sure to find a veterinarian that specializes in reptile care.
  • Parasite control: They are prone to parasites, so it’s important to have them checked regularly for parasites like mites and ticks.
  • Shedding: Iguanas shed their skin regularly, so make sure to provide a humid hide to help them shed and remove any retained shed.
  • Behavioral changes: Watch for any changes in your iguana’s behavior, appetite, or activity level, as these can be signs of illness.

Handling and interaction

Iguanas can become quite affectionate with their owners, but they require proper handling and interaction to prevent injury or stress. Here are some tips to keep in mind:

  • Approach slowly: Iguanas can be skittish, so approach them slowly and calmly.
  • Support their body: When picking up your iguana, support their body with both hands.
  • Avoid the tail: Iguanas can use their tails as a defense mechanism, so avoid grabbing their tail.
  • Give them space: Iguanas need space to move around and explore, so provide them with plenty of room to do so.
  • Socialization:They can benefit from socialization with their owners, but make sure to do so slowly and carefully to prevent stress or injury.


Iguanas make fascinating and rewarding pets, but they require a significant amount of care and attention. By following the guidelines outlined in this care guide, you can provide your iguana with a happy and healthy life.

Remember to choose the right type of iguana for your lifestyle and living situation, provide a large and properly equipped habitat, feed them a balanced diet, and provide regular healthcare and socialization. With proper care, your pet can become a beloved member of your family.
