By the conclusion of this article, you will have gained valuable insights into your pet’s behavior, enabling you to offer the most appropriate and effective care. With that in mind, let us explore the fascinating realm of leopard gecko communication and demystify the enigma of clicking sounds.

What is a Clicking Noise and Why Does It Occur in Leopard Geckos?


Clicking noise in leopard geckos is a unique sound that serves as an essential means of communication between these reptiles. The noise is generated when the gecko rapidly opens and closes its mouth, producing a series of clicks that other geckos or even their caretakers can hear. Depending on the context and the gecko’s specific needs, these clicking sounds may convey various messages or emotions.

To better understand the reasons behind clicking noises in leopard geckos, consider the following explanations:

Stress or Fear

When a gecko is experiencing stress or feels threatened by a potential predator, it may produce clicking sounds as a defensive mechanism. This auditory signal can deter predators or alert the gecko’s owner to its distress, prompting appropriate action to alleviate the stressor.

Territorial Behavior

Leopard geckos are known to be territorial creatures. The clicking noise may serve as a warning to other geckos or animals encroaching upon their territory. When you hear clicking sounds in this context, it is the gecko’s way of asserting dominance and maintaining control over its space.

Mating Call

During the breeding season, leopard geckos may use clicking noises to communicate their reproductive intentions. These sounds can help to attract potential mates or signal their readiness to engage in mating behaviors. In such instances, clicking noises are a crucial part of the gecko’s reproductive process.

Excitement or Curiosity

Occasionally, clicking noises may not be directly linked to stress, territoriality, or mating. Instead, they might express the gecko’s excitement or curiosity about its surroundings. When exploring a new environment or encountering an unfamiliar object, a leopard gecko may produce clicking sounds as it investigates.

To accurately determine the cause of clicking noises in your leopard gecko, it is essential to observe the context in which these sounds occur and any accompanying behaviors. By closely monitoring your gecko’s actions and environment, you will be better equipped to identify the underlying reason for the clicking noises and provide the necessary care and attention to address your pet’s specific needs.

Possible Reasons for Clicking Noise in Leopard Geckos


As leopard gecko caretakers, it is crucial to understand how our reptilian companions communicate with us and one another. One such form of communication is the distinctive clicking noise you may have observed your leopard gecko making occasionally. While these sounds can be intriguing, it is important to comprehend their significance to provide the best possible care for your pet.

In this section of our blog, we will delve deeper into the possible reasons behind the clicking noises produced by leopard geckos. By examining these underlying causes, you will be better equipped to address your gecko’s needs and maintain a healthy, comfortable environment for your pet. 

Respiratory Infections 

Respiratory infections in leopard geckos may cause clicking sounds as the gecko struggles to breathe. The noise can result from excess mucus or inflammation in the airways. If you notice other symptoms, such as wheezing, labored breathing, or nasal discharge, it is crucial to consult a veterinarian experienced with reptiles to diagnose and treat the infection promptly.

Mouth Rot

Mouth rot, or infectious stomatitis, is a common condition in reptiles that can cause clicking noises. Inflamed and swollen oral tissue may make it difficult for your gecko to close its mouth correctly, leading to a clicking sound. If you observe other signs, such as a discolored, pus-filled mouth or a loss of appetite, seek veterinary care to address this issue.


Internal parasites can cause discomfort and stress in leopard geckos, leading to clicking noises. Parasites may affect your gecko’s digestive system, causing it to feel bloated or experience pain. If you notice changes in your gecko’s feces, weight loss, or decreased activity levels, consult a veterinarian for proper diagnosis and treatment.


Stress is another reason why leopard geckos may produce clicking noises. Various factors can contribute to stress, such as an inadequate or overcrowded habitat, sudden changes in the environment, or the presence of other pets. It is important to closely monitor your gecko’s behavior and living conditions to minimize stress and ensure its well-being.

In conclusion, leopard geckos may make clicking noises due to health issues or stress. Paying close attention to their behavior, environment, and physical condition will help you identify the cause and take appropriate action to maintain a healthy and happy pet.

Signs and Symptoms of Clicking Noise in Leopard Geckos


Clicking noises in leopard geckos can accompany various signs and symptoms that provide insight into the underlying cause. Here are some key indicators to watch for:

  • Difficulty breathing: If your gecko struggles to breathe, clicking noises may indicate a respiratory infection or other health issues.
  • Wheezing or labored breathing can signal respiratory distress or a possible respiratory infection, requiring immediate veterinary attention.
  • Oral discoloration or pus: If you notice discolored, inflamed, or pus-filled oral tissue, this may indicate mouth rot and should be addressed by a veterinarian.
  • Loss of appetite: A decrease in appetite could be a sign of an underlying health issue, such as mouth rot or parasites, which may also cause clicking noises.
  • Changes in feces: If your gecko’s feces appear abnormal or infrequent, this may suggest the presence of parasites, which can cause discomfort and clicking sounds.
  • Weight loss or lethargy: These symptoms could indicate internal parasites or another health issue that requires veterinary intervention.
  • Agitated or defensive behavior: This may suggest that your gecko is stressed or feeling threatened, potentially causing clicking noises as a warning signal.

By closely monitoring your leopard gecko for these signs and symptoms, you can better understand the reasons behind the clicking noises and take appropriate action to address potential health or environmental issues.

How to Prevent Clicking Noise in Leopard Geckos

To prevent clicking noises in leopard geckos, it is essential to maintain an appropriate habitat with the correct size, temperature, and humidity levels while avoiding overcrowding by providing ample space and hiding spots for each gecko. Monitoring environmental changes and keeping the enclosure clean can help reduce stress, as can offering a balanced diet to ensure optimal health. Regularly checking your gecko for signs of illness and scheduling routine veterinary check-ups can also help detect and address potential health issues, minimizing clicking noises due to stress or health problems.

When to Consult a Veterinarian

It is advisable to consult a veterinarian experienced in reptile care when your leopard gecko makes a sound accompanied by any of the following signs or symptoms, as these may indicate an underlying health issue:

  • Persistent or worsening clicking noises, especially if accompanied by signs of respiratory distress, such as wheezing, labored breathing, or nasal discharge.
  • Clicking noises are associated with oral discoloration, inflammation, or pus, which may suggest mouth rot.
  • A sudden change in your gecko’s appetite or weight loss with clicking noises potentially indicates parasites or another health concern.
  • Any abnormal behavior, such as lethargy, agitation, or an inability to move correctly, combined with clicking noises.

If you are uncertain about the cause of the clicking noises or concerned about your gecko’s well-being, it is always best to consult a veterinarian for professional advice and appropriate care. Early intervention can help prevent complications and ensure the health and happiness of your leopard gecko.
