Have you heard people claim that iguanas purr when they’re content or relaxed? It’s a curious thought, but is there any truth to it? If you’re an iguana owner or simply a reptile enthusiast, you may have wondered about the sounds these majestic creatures make and what they mean.
In this blog, we’ll unpack the myths surrounding iguanas “purring,” clarify the reality of their vocal abilities, and provide insights into what specific behaviors and noises might actually indicate. By the end, you’ll have a clear understanding of why iguanas definitely don’t purr and how to interpret their actions and sounds.
Can Iguanas Purr?
The short answer is no—iguanas cannot purr. Unlike cats, which produce a distinctive vibrating sound through their vocal cords, iguanas lack the physical anatomy required to create this kind of noise. Iguanas do not have vocal cords, which rules out the possibility of “purring” as a feature of their communication.
However, iguanas can make other sounds that are sometimes mistaken for purring. Understanding these noises is essential to ensure the health and happiness of your pet iguana.
Sounds Iguanas Make That Could Be Misunderstood
Gurgling Noises
One of the most common sounds that can be mistaken for purring is a gurgling noise. This occurs when a small amount of food or liquid remains in the iguana’s throat, and it makes a sound when the iguana moves its head up or down.
Key facts about gurgling:
- When It Happens: Right after eating or drinking.
- Triggered By: Often occurs if the iguana is touched or stimulated shortly after a meal.
- What To Do: Avoid handling or petting your iguana during or immediately after feeding to prevent discomfort. If the gurgling persists, consult a veterinarian to rule out any airway issues.
Hissing
Iguanas may also hiss, especially when they feel threatened or stressed. This sound is entirely different from purring and is usually accompanied by other telltale signs of defensive behavior, such as puffing up their body or whipping their tail.
Common Myths About Iguanas “Purring”
There are a number of misconceptions circulating within the pet community about why iguanas “purr.” Here are the top myths—and the truth behind them:
Myth 1: Purring Means They’re Happy
Some pet owners believe that their iguana purrs as a sign of contentment, similar to cats. However, iguanas express happiness and contentment through body language, not sound. A relaxed iguana will lie flat on its belly, with limbs loosely extended to the sides. The tail may also rest flat, and they might drape their back leg over it. This posture indicates they feel safe and calm.
Myth 2: Purring Happens When Iguanas Are Tired
Another misconception is that iguanas make purring sounds when they’re tired. This isn’t accurate either; most iguanas indicate fatigue by simply finding a comfortable spot to rest. They generally become still and quiet, without producing any specific noises.
Myth 3: Purring Shows They Like Being Petted
Some iguana owners claim their pet makes a purring sound in response to affection, such as being stroked or held. While iguanas may make gurgling sounds after eating or drinking, this does not indicate affection. In fact, iguanas can interpret being touched during this time as stressful rather than comforting.
Why Don’t Iguanas Purr?
To understand why purring simply doesn’t exist in iguanas, we need to look at the biology behind it. Purring in animals like cats is generated by the vibrating of their vocal cords. Iguanas, however, lack vocal cords altogether, which makes true purring an anatomical impossibility.
Additionally, from a behavioral perspective, there’s no evolutionary reason for iguanas to develop a purring sound. Unlike mammals, iguanas don’t communicate nuanced emotions or feelings through vocalization. Instead, they rely heavily on body language and physical displays to signal their mood, intentions, or level of comfort.
How to Recognize When Your Iguana Is Content
Although iguanas don’t purr, they do have other ways of showing that they’re happy and well-adjusted. Here are some things to observe:
- Relaxed Posture: They lie flat, with limbs and tail fully extended or resting naturally.
- Consistent Appetite: A happy iguana will eat regularly and show interest in their food.
- Bright Eyes: Clear, alert, and healthy-looking eyes are a good indicator of both emotional and physical well-being.
- Calm Movements: They move slowly and deliberately around their enclosure, avoiding erratic or defensive behaviors.
If your iguana exhibits these behaviors, congratulations! You’re providing them with an environment where they feel safe and happy.
Misinterpreted Sounds and Helpful Tips
If your iguana is making unexpected noises, it’s always a good idea to observe and analyze the context:
- Check for Stress: If the sound resembles hissing or aggressive exhalation, your iguana might feel threatened. Look for accompanying stress signals, such as a puffed-up body or defensive tail whipping.
- Timing is Key: Any gurgling noise occurring after eating or drinking is likely related to residual food or liquid. Avoid handling them during or right after a meal to minimize this response.
- Health Check: Persistent noises could indicate a health concern, such as partial obstructions or respiratory issues. Schedule a visit to your veterinarian if you notice anything unusual.
A Final Word on Iguanas and Sounds
The idea of iguanas purring may sound charming, but it’s simply not based in fact. These fascinating reptiles rely on body language, not vocal sounds, to express their emotions. While gurgling sounds or other noises can happen occasionally, they are typically a simple byproduct of eating or drinking.
By learning to recognize and interpret your iguana’s behaviors and sounds accurately, you can ensure their needs are met and foster a trusting relationship between you and your pet. When in doubt, rely on professional advice to keep them in the best of health.
