Leopard geckos have become popular pets for reptile enthusiasts due to their unique appearance and low maintenance requirements. However, one of the most common concerns for leopard gecko owners is when their beloved pet stops eating. In this blog, we will explore the possible reasons behind a leopard gecko’s loss of appetite and provide fact-checked solutions to help address the issue effectively.

Normal Feeding Behavior of Leopard Geckos:


Leopard geckos have specific feeding habits that are important to understand when assessing their appetite. As primarily insectivorous reptiles, their diet consists mainly of live insects such as crickets, mealworms, and dubia roaches. These insects should be gut-loaded, meaning they are fed a nutritious diet before being offered to the gecko. This ensures that the gecko receives optimal nutrition from its prey.

Leopard geckos have a voracious appetite, and their feeding frequency depends on their age and size. Younger geckos require more frequent meals, while adult geckos can be fed every other day or every three days. The portion size should be appropriate for their age and should not exceed the size of their head.

Common Reasons for Leopard Geckos Not Eating:


A. Shedding:

Shedding is a natural process for leopard geckos as they grow. It involves the shedding of the outer layer of their skin to accommodate their increasing size. During the shedding process, geckos may experience discomfort and become less interested in eating.

To determine if shedding is the cause of your gecko’s reduced appetite, observe their behavior and look for signs such as dull and whitish skin, increased time spent in their moist hide, and possible agitation. Providing a moist hide with damp moss or paper towels in their enclosure can create a humid microclimate that aids in shedding.

It’s important to note that shedding can take several days, and it’s crucial to avoid forcibly removing old skin. Attempting to peel the skin can cause injuries and stress to your gecko. Instead, allow them to shed naturally at their own pace.

B. Temperature and Lighting:

Leopard geckos are ectothermic, meaning they rely on external sources of heat to regulate their body temperature. Incorrect temperature and lighting conditions in their enclosure can impact their appetite and overall health.

Proper temperature gradients within the enclosure are essential for leopard geckos. The warm side of the habitat should be maintained at around 88-92°F (31-33°C), while the cool side should be around 75-80°F (24-27°C). This temperature range allows geckos to thermoregulate by moving between warmer and cooler areas as needed.

Using appropriate heat sources such as heat mats, ceramic heat emitters, or overhead heating elements, along with a thermostat for temperature regulation, ensures the gecko’s environment remains consistent and within the optimal range.

In addition to temperature, providing a UVB light source is crucial for leopard geckos. UVB light helps them synthesize vitamin D3, which is necessary for proper calcium absorption and overall bone health. Make sure to choose a reputable UVB light specifically designed for reptiles and follow the manufacturer’s instructions for optimal placement and duration of exposure.

C. Illness or Injury:

Health issues can significantly impact a leopard gecko’s appetite. Digestive problems, mouth infections, parasites, or other illnesses can all lead to a decreased desire to eat. If you observe your gecko experiencing weight loss, lethargy, changes in stool consistency, or any other abnormal behavior, it is crucial to consult a reptile veterinarian. 

A qualified veterinarian can conduct a thorough examination, possibly perform diagnostic tests, and provide appropriate treatment options. Early detection and intervention can prevent further complications and help restore your gecko’s appetite.

D. Environmental Stress:

Leopard geckos are sensitive to their environment, and stress can have a significant impact on their appetite. Factors such as overcrowding, excessive handling, loud noises, or a lack of hiding spots can all contribute to stress in leopard geckos.

Creating a suitable and stress-free environment is vital to encourage eating. Ensure that the enclosure is spacious enough for your gecko to move around comfortably. Provide multiple hiding spots using rocks, logs, or artificial caves to create a sense of security for your gecko.

Minimize handling to reduce stress levels, especially during the acclimation period or when they are going through other stressful events, such as moving to a new enclosure. When handling is necessary, do so gently and avoid any sudden or rough movements.

Keep noise levels in the gecko’s environment to a minimum, as loud noises and disturbances can stress them out. Try to place the enclosure in a quiet area of your home where they can feel safe and undisturbed.

Solutions to Encourage Eating:


A. Monitoring and Observing:

Closely monitor your leopard gecko’s behavior and feeding patterns. Maintaining a feeding log can be a useful tool to track any changes in their eating habits. Note the type and amount of food offered, as well as their response to it. This information can provide valuable insights and help identify potential triggers or underlying issues that may be affecting their appetite.

B. Offering a Variety of Food:

Leopard geckos can become bored with a monotonous diet, which can contribute to a loss of appetite. To stimulate their interest in food, offer a variety of insects as part of their diet. In addition to crickets and mealworms, consider incorporating dubia roaches, waxworms, silkworms, or other suitable prey options.

It’s important to ensure the insects are of appropriate size and gut-loaded for optimal nutrition. Gut-loading involves feeding the insects a nutritious diet before offering them to your gecko. This boosts their nutritional content, which in turn benefits your gecko’s overall health.

To further enhance the nutritional value of the insects, dust them with a calcium supplement and a multivitamin powder. Calcium is essential for proper bone development and muscle function, while multivitamins help ensure a well-rounded nutrient intake. Follow the recommended guidelines for supplementing and be mindful not to overdo it.

C. Assisting with Shedding:

If you suspect that shedding is the cause of your leopard gecko’s reduced appetite, you can provide assistance to facilitate the process. Create a moist hide within their enclosure by placing damp moss or paper towels in a designated area. The increased humidity in the hide helps soften the old skin, making it easier for your gecko to shed.

Monitor the humidity levels in the enclosure to ensure they are within the appropriate range for shedding. Aim for a humidity level of around 40-50%. Using a hygrometer can help you accurately measure and maintain the humidity.

D. Addressing Temperature and Lighting Issues:

Maintaining the proper temperature gradient and providing appropriate lighting conditions are crucial for the overall well-being and appetite of leopard geckos.

Regularly check the temperatures within the enclosure using thermometers placed in different areas. This will help you ensure that the warm side of the habitat remains between 88-92°F (31-33°C) and the cool side between 75-80°F (24-27°C).

Use reliable heat sources such as heat mats, ceramic heat emitters, or overhead heating elements to create and maintain the necessary temperature gradient. It’s important to use a thermostat to regulate the heat sources accurately and prevent overheating or chilling.

In terms of lighting, consider providing a UVB light source. UVB light helps leopard geckos synthesize vitamin D3, which is crucial for calcium absorption and overall health. Choose a reputable UVB light specifically designed for reptiles and follow the manufacturer’s instructions regarding placement and duration of exposure.

E. Veterinary Consult

If your leopard gecko’s loss of appetite persists despite implementing the above solutions or if you notice any other concerning symptoms, it is essential to seek professional advice from a reptile veterinarian. Reptile veterinarians have specialized knowledge and experience in diagnosing and treating reptile-specific health issues.

During a veterinary consultation, the veterinarian will conduct a thorough examination of your gecko. They may ask about the gecko’s feeding habits, environmental conditions, and any recent changes that could be contributing to the loss of appetite. In some cases, they may recommend further diagnostic tests, such as fecal exams or blood work, to identify any underlying health issues.

Based on their findings, the veterinarian will provide appropriate treatment options. This may include medications to address specific health conditions, dietary adjustments, or additional guidance on environmental factors that could be affecting your gecko’s appetite. Following the veterinarian’s recommendations is crucial for your gecko’s recovery and overall well-being.


Understanding the reasons behind a leopard gecko’s loss of appetite is crucial for addressing the issue effectively. By considering factors such as shedding, temperature and lighting, illness or injury, and environmental stress, you can take appropriate steps to encourage your gecko to eat again.

Remember to closely monitor their behavior, offer a varied diet, provide assistance during shedding, maintain appropriate temperature and lighting conditions, and seek veterinary help when necessary. Each gecko is unique, and it may take time and patience to identify and resolve the underlying cause of their appetite loss. By providing the proper care and attention to their specific needs, you can support your leopard gecko’s appetite and ensure their continued health and happiness as cherished pet.
