Why Do Leopard Geckos Scream? Understanding the Behavior of Your Pet Gecko

Leopard geckos have a muscular throat that allows them to make sounds, similar to a human’s voice box. Their vocal cords are located in the larynx and are responsible for producing sound. When a leopard gecko makes a noise, air is forced from the lungs into the larynx, causing the vocal cords to vibrate and produce sound.

Why Do Leopard Geckos Scream?

Leopard geckos can scream for various reasons, including natural behaviors in the wild, territorial defense, mating calls, and predator warning calls.

Natural Behaviors in the Wild

In the wild, leopard geckos are nocturnal, and they use vocalizations to communicate with other geckos. Screaming is a natural behavior for leopard geckos, and it can be used to alert other geckos of potential danger, find mates, or establish territory.

Territorial Defense

Leopard geckos can also scream as a form of territorial defense. In the wild, they will defend their territory against other geckos or predators. When threatened, a leopard gecko may scream to scare off the intruder or warn other geckos of potential danger.

Mating Calls

Male leopard geckos may scream to attract females during breeding season. Males will make a series of calls to signal their presence, and females will respond with their own vocalizations to indicate their interest.

Predator Warning Calls

Leopard geckos can also scream to warn other geckos of predators. When threatened, they emit a high-pitched scream that alerts other geckos to the danger. This behavior is common in younger leopard geckos that are more vulnerable to predators.

Identifying Screaming Behavior in Your Leopard Gecko

Identifying screaming behavior in your leopard gecko can be challenging, but there are a few physical signs and vocalizations to look out for.

Physical Signs and Vocalizations

When a leopard gecko screams, they may open their mouth wide, exposing their throat. They may also puff up their body to make themselves appear larger. Vocalizations can range from a high-pitched scream to a throaty growl.

How to Respond to Screaming Behavior

If your leopard gecko starts screaming, it’s essential to respond appropriately to ensure their safety and well-being.

Proper Handling Techniques

If your leopard gecko is screaming due to stress or fear, it’s essential to handle them gently and avoid any sudden movements. Slowly and calmly pick up your gecko, supporting their body at all times, and place them in a quiet, stress-free environment.

Creating a Stress-Free Environment

To prevent your leopard gecko from screaming due to stress, it’s essential to provide them with a comfortable and secure habitat. Ensure that their enclosure is the correct size, with plenty of hiding spots, and that the temperature and humidity levels are appropriate.

Common Misconceptions about Screaming Behavior

There are several common misconceptions about leopard gecko screaming behavior that are important to understand.

Aggression vs. Fear

Many owners assume that their leopard gecko is being aggressive when they scream. However, screaming is often a sign of fear or stress. It’s essential to respond appropriately to ensure your gecko feels safe and secure.

Screaming Frequency and Health Concerns

While occasional screaming is entirely normal for leopard geckos, frequent or constant screaming can be a sign of underlying health issues. If your gecko is screaming excessively, it’s essential to take them to a veterinarian for a checkup.


In conclusion, leopard geckos scream for various reasons, including natural behaviors in the wild, territorial defense, mating calls, and predator warning calls. Understanding why your pet gecko is screaming can help you better care for them and respond appropriately to ensure their safety and well-being.
