Pet Iguana: You Need to Know This Before Bringing One Home

Iguanas are fascinating reptiles that have become increasingly popular as exotic pets. However, these magnificent creatures come with significant care requirements that potential owners should carefully consider before making the commitment. This comprehensive guide explores the realities of keeping an iguana as a pet, from their size and temperament to their specialized care needs.

Understanding Green Iguanas: The Most Common Pet Iguana

The green iguana (Iguana iguana), also known as the American iguana or common green iguana, is the species most frequently kept as a pet. These large, arboreal reptiles are native to Central and South America and are primarily herbivorous.

Size and Growth

One of the most important considerations for potential iguana owners is their impressive size:

– Green iguanas can grow to 5-7 feet in length (including tail)
– They typically weigh between 15-20 pounds when fully grown
– Males are generally larger than females
– They reach full size in about 3-4 years

Many new owners purchase baby iguanas without realizing how large they’ll become. This significant growth requires increasingly spacious enclosures, which is a major commitment in terms of both space and finances.

Lifespan

Green iguanas have a remarkably long lifespan when properly cared for:

– 15-20 years in captivity is common
– Some well-cared-for iguanas have lived beyond 20 years

This long-term commitment should not be taken lightly, as iguanas require consistent, specialized care throughout their lives.

Iguana Care Requirements

Iguanas have complex care needs that make them challenging pets, especially for beginners.

Housing Requirements

The housing needs of iguanas are extensive and expensive:

– Adult iguanas require enclosures at least 6 feet tall, 6 feet long, and 4 feet wide
– Custom-built enclosures are often necessary
– The habitat must include climbing branches, basking spots, and hiding areas
– Proper substrate such as reptile carpet, newspaper, or tile is needed
– The enclosure must be secure, as iguanas are excellent escape artists

Temperature and Lighting

Iguanas have specific environmental requirements:

– Basking spots should be 95-100°F (35-38°C)
– Ambient temperature should be 80-85°F (27-29°C)
– UVB lighting is essential for calcium metabolism and preventing metabolic bone disease
– 12-14 hours of light daily, simulating their natural tropical environment
– Proper humidity levels of 70-80% are necessary

Diet and Nutrition

Contrary to some misconceptions, iguanas are herbivores with specific dietary needs:

– Diet should consist of 80-90% dark, leafy greens (collard greens, mustard greens, dandelion)
– Remaining diet should include vegetables and limited fruits
– Commercial iguana food can supplement but shouldn’t be the primary food source
– Calcium and vitamin supplements are typically necessary
– Protein sources like insects or meat should NOT be fed to iguanas

Improper diet is one of the leading causes of health problems in captive iguanas, making proper nutrition absolutely critical.

Temperament and Handling

Iguanas are not naturally tame and can present behavioral challenges:

Aggression Issues

– Males especially can become territorial and aggressive during breeding season
– Tail whipping, biting, and scratching are common defensive behaviors
– Some iguanas never fully tame, regardless of handling efforts
– They can inflict serious injuries with their sharp claws, teeth, and powerful tails

Taming and Socialization

– Requires consistent, gentle handling from a young age
– Can take months or years of patient work
– Some individuals may always remain somewhat wild
– Iguanas recognize their owners but form different bonds than mammals

According to experienced reptile keepers on forums like r/reptiles, “They can be tough to tame and may never become completely docile pets.” This reality should be considered by anyone expecting an immediately friendly pet.

Health Concerns

Iguanas are prone to several health issues, many resulting from improper care:

– Metabolic bone disease from insufficient UVB lighting or calcium
– Respiratory infections from inadequate temperature or humidity
– Impaction from inappropriate substrate
– Egg binding in females
– Parasitic infections

Finding a veterinarian who specializes in reptiles is essential, as not all vets are equipped to treat iguanas properly. Regular health check-ups can help prevent or address issues early.

Is an Iguana the Right Pet for You?

Before deciding to bring home an iguana, honestly assess:

– Do you have adequate space for a large enclosure?
– Can you commit to 15-20 years of specialized care?
– Are you prepared for the financial commitment? (Initial setup can cost $500-1,000+)
– Do you have access to a reptile veterinarian?
– Are you patient enough to work with a pet that may never be fully tame?
– Can you provide the proper diet consistently?

As noted in reptile communities, green iguanas are “very not beginner friendly.” They require significant knowledge, resources, and commitment.

Alternatives to Green Iguanas

If you’re interested in reptiles but concerned about the challenges of iguana ownership, consider these more manageable alternatives:

– Bearded dragons: Smaller, generally more docile, and easier to care for
– Leopard geckos: Require less space and have simpler care requirements
– Blue-tongued skinks: Relatively docile and have less complex housing needs

These reptiles still require specialized care but are generally more suitable for beginners than iguanas.

Conclusion

While iguanas can be rewarding pets for the right owner, they are not suitable for everyone. Their size, specialized care requirements, potential for aggression, and long lifespan make them challenging pets that demand significant commitment. As Petco notes, “when owners are equipped with the proper care information and necessary products, iguanas can be one of the most rewarding pet reptiles.” However, this reward comes only after substantial investment of time, space, money, and effort.

If you’re still interested in an iguana after considering these factors, take time to research thoroughly, connect with experienced iguana keepers, and prepare properly before bringing one home. Responsible ownership ensures both your satisfaction and the well-being of these magnificent reptiles.
