2. Essential Factors Influencing Iguana Lifespan

Several key factors directly influence how long do pet iguanas live. Meeting these needs is critical to ensuring a long and healthy life for your iguana.

2.1. Proper Diet and Nutrition

A well-balanced diet is essential for an iguana’s health and longevity. Wild iguanas are primarily herbivores, feeding on a variety of leaves, fruits, and flowers. Replicating this diet in captivity is crucial.

Key Dietary Components:

Leafy Greens (60-70%): Collard greens, mustard greens, turnip greens, dandelion greens, and escarole should form the foundation of their diet. Avoid spinach, kale, and broccoli in large amounts due to their oxalic acid content, which can bind calcium.
Vegetables (20-30%): Include a variety of vegetables such as butternut squash, sweet potatoes, carrots, green beans, and bell peppers.
Fruits (5-10%): Offer fruits sparingly as treats, such as berries, mangoes, papayas, and figs.
Calcium and Vitamin D3 Supplementation: Supplementation is essential, especially for young, growing iguanas. Dust their food with a calcium supplement daily and a vitamin D3 supplement a few times a week.

Foods to Avoid:

Animal Protein: Iguanas are herbivores and cannot properly digest animal protein, which can lead to kidney problems. Avoid feeding them insects, meat, or eggs.
Commercial Iguana Food: Many commercial iguana diets are not nutritionally complete and can be high in protein.
Spinach, Kale, and Broccoli (in excess): These contain oxalates, which can inhibit calcium absorption.

Providing a varied and nutritious diet is one of the most important steps you can take to extend your iguana’s lifespan.

2.2. Optimal Housing and Environmental Conditions

Creating the right environment for your iguana is crucial for their well-being. Iguanas require specific temperature, humidity, and lighting conditions to thrive.

Enclosure Size:

Iguanas need a large enclosure to accommodate their size and activity level. A young iguana may start in a smaller enclosure, but they will quickly outgrow it. An adult iguana requires a custom-built enclosure or a large commercial reptile enclosure. The minimum size for an adult iguana enclosure is:

Measurement	Size
Length	Twice the iguana’s length
Width	The iguana’s length
Height	At least 6 feet

Temperature Gradient:

Iguanas need a temperature gradient within their enclosure, allowing them to regulate their body temperature.

Temperature Zone	Temperature Range
Basking Spot	95-100°F (35-38°C)
