Why Is My Leopard Gecko Not Eating?

‍Leopard geckos are fascinating reptiles known for their unique appearance and docile nature. However, one of the most concerning issues that leopard gecko owners may encounter is when their beloved pet stops eating. This can be distressing for both novice and experienced owners alike. In this comprehensive guide, we will explore the common reasons why leopard geckos may refuse to eat and provide helpful solutions to bring back their appetite.

Common Reasons Why Leopard Geckos Stop Eating

1. Environmental Factors: Temperature and Lighting

One of the primary reasons why leopard geckos may go off their food is incorrect temperature and lighting conditions in their enclosure. These reptiles are ectothermic, which means they rely on external heat sources to regulate their body temperature and metabolism. If the temperature in their habitat is too cold, their metabolism slows down, making it difficult for them to digest their food properly. It is crucial to maintain the appropriate temperature gradient within the enclosure to ensure optimal digestion and overall health.

2. Fecal Impaction

Fecal impaction is another common issue that can lead to appetite loss in leopard geckos. This occurs when foreign objects, such as loose substrate or undigested food, become lodged in their digestive system. Impaction can cause discomfort and hinder the gecko’s ability to eat. Providing proper hydration and gentle massages during a lukewarm bath can help alleviate mild impactions. However, severe cases may require veterinary intervention.

3. Shedding

Leopard geckos regularly shed their skin to accommodate their growth. During the shedding process, geckos may experience a decrease in appetite. This is a natural behavior, as their energy is focused on shedding the old skin. It is important to create a humid hide within their enclosure to facilitate the shedding process and ensure that any retained shed doesn’t cause further complications.

4. Brumation

Brumation is a period of reduced activity and metabolic slowdown observed in many reptiles during colder months. Leopard geckos may enter a brumation-like state if the ambient temperature drops too low. This can result in a decrease in appetite. It’s crucial to provide a consistent and appropriate temperature range within their enclosure to prevent unnecessary brumation.

5. Breeding Season

During the breeding season, both male and female leopard geckos may exhibit a loss of appetite. Females may experience a decrease in appetite as they prepare for ovulation and egg-laying. Males, on the other hand, may lose interest in food as they focus on mating behaviors. These changes in appetite are normal during the breeding season, but extreme weight loss should be monitored and addressed by a veterinarian.

6. Stress and Environmental Changes

Leopard geckos are sensitive creatures, and stress can significantly impact their eating habits. Environmental changes, such as moving to a new enclosure or introducing new tank mates, can cause stress and lead to appetite loss. It is important to provide a secure and comfortable environment for your gecko and minimize any potential stressors.

7. Underlying Health Issues

Loss of appetite can also be a symptom of underlying health issues in leopard geckos. Respiratory infections, mouth rot, parasitic infections, and metabolic bone disease are just a few examples of conditions that can affect their overall well-being and appetite. If you suspect any health issues, it is crucial to seek veterinary care for proper diagnosis and treatment.

8. Picky Eaters

Just like humans, leopard geckos can have individual preferences when it comes to food. Some geckos may be picky eaters and refuse certain types of insects or prey items. Offering a variety of food options can help ensure that your gecko finds something they enjoy and will eat.

9. Seasonal Changes and Natural Cycles

Leopard geckos, like many animals, experience natural cycles and behavioral changes throughout the year. These cycles can affect their appetite. For example, during the colder months, leopard geckos may naturally reduce their food intake and enter a state of reduced activity. This is a normal response to changes in their environment.

10. Injury or Illness

Injury or illness can cause a leopard gecko to lose its appetite. Physical injuries, such as wounds from fights or accidents within the enclosure, can lead to reduced food intake as the gecko focuses on healing. Additionally, various health conditions, including respiratory infections, skin infections, and digestive issues, can result in appetite loss. It is important to monitor your gecko closely and seek veterinary care if you suspect any injuries or illnesses.

How to Encourage Your Leopard Gecko to Eat Again

When your leopard gecko stops eating, it is essential to address the underlying cause and take appropriate measures to encourage their appetite. Here are some strategies you can try:

1. Ensure Proper Heating and Lighting

Maintaining the correct temperature gradient is crucial for leopard geckos’ overall health and appetite. Use heat mats, heat rocks, or ceramic heat emitters to provide a warm basking spot and ensure the ambient temperature remains within the recommended range. Additionally, consider providing low-level UVB lighting or appropriate supplements to meet their nutritional needs.

2. Create a Suitable Environment

Leopard geckos thrive in a well-designed and comfortable enclosure. Provide hiding spots, a humid hide for shedding, and a clean and hygienic environment. Minimize stressors such as excessive handling or aggressive tank mates to create a calm and secure space for your gecko.

3. Offer a Variety of Food Options

Leopard geckos can be picky eaters, so offering a variety of food options can increase the chances of finding something they enjoy. Experiment with different insects, such as crickets, mealworms, or dubia roaches, to find their preferred choice. Ensure the prey items are appropriately sized and gut-loaded for optimal nutrition.

4. Address Health Issues

If your leopard gecko’s appetite loss is accompanied by other concerning symptoms or persists for an extended period, seek veterinary care. A veterinarian can assess your gecko’s health, conduct necessary tests, and provide appropriate treatment for any underlying health issues.

5. Monitor Weight and Behavior

Regularly weigh your gecko to track any significant changes in weight. Sudden and excessive weight loss can indicate a more serious problem. Additionally, observe your gecko’s behavior for signs of distress, lethargy, or abnormal activity. Any concerning changes should be addressed promptly.

6. Maintain Hydration

Proper hydration is essential for leopard geckos’ overall health and digestion. Provide a shallow water dish with fresh water at all times. Additionally, consider offering a lukewarm bath to aid in hydration and promote healthy bowel movements.

7. Avoid Force-Feeding

Force-feeding should only be considered as a last resort and performed under the guidance of a veterinarian. It can be stressful and potentially harmful if not done correctly. Exhaust all other options and consult with a reptile specialist before attempting force-feeding.

When to Seek Veterinary Care

While some appetite loss in leopard geckos can be temporary and easily resolved, persistent or severe cases require veterinary attention. You should consult a reptile veterinarian if:

  • Your gecko’s appetite loss persists for more than a week.
  • Weight loss is significant and rapid.
  • Your gecko displays other concerning symptoms, such as lethargy, respiratory issues, or abnormal behavior.
  • You suspect an injury or underlying health condition.

A reptile veterinarian can provide a thorough examination, perform necessary tests, and recommend appropriate treatment options based on your gecko’s specific needs.


Understanding the reasons behind a leopard gecko’s appetite loss is crucial for their overall well-being. By addressing environmental factors, providing a suitable enclosure, offering a varied diet, and monitoring their health, you can help encourage your gecko to eat again. Remember to consult a veterinarian if you have any concerns or if the appetite loss persists. With proper care and attention, your leopard gecko will thrive and regain its healthy appetite once again.
