As a leopard gecko owner, you may wonder how long your pet can go without food. Understanding your gecko’s eating habits and capacity to withstand periods without eating is essential for keeping it healthy and happy.

Leopard geckos can go without food for varying lengths of time, depending on age, size, and overall health. Adult geckos can survive between 10 and 14 days without food due to the fat storage in their tails. In contrast, younger geckos need more frequent feeding, with baby leopard geckos requiring daily nourishment.

Knowing these basic aspects of your gecko’s dietary needs will help you maintain a proper feeding schedule and ensure its well-being.

How Long Can Leopard Geckos Go Without Food?

Leopard geckos, like all reptiles, have unique dietary needs that change throughout their lives. For baby and younger leopard geckos, it is essential to provide them with food daily, as they are still growing and need the nutrients to maintain their development.

As your leopard gecko matures, its ability to survive without food for longer periods increases. Adult leopard geckos typically can go between 10 and 14 days without food, relying on the fat stored in their tails for energy.

During colder months or periods of brumation, some healthy adult geckos may even go without food for up to 3 months.

However, it’s crucial to be aware of your gecko’s overall condition and ensure they have access to food as needed. Age, temperature, and overall health can impact how long your leopard gecko can thrive without food.

Monitor your gecko and adjust its diet and tank conditions accordingly to maintain its well-being.

Factors Affecting Duration

It’s crucial to understand the factors that can impact how long your leopard gecko can go without food. These factors include their age, health, and metabolism. Let’s dive in and see what role each factor plays.


Age is one of the most important factors in determining how long your leopard gecko can go without food. Young geckos, such as babies (0-2 months old) and juveniles (2-6 months old), can’t go without food for more than 2 days and 2-7 days, respectively.

However, sub-adult (6-12 months old) and adult (over 12 months old) geckos can go longer without food, ranging from 7-14 days to over a month.


Your gecko’s overall health also plays a significant role in its ability to withstand periods without food. A healthy leopard gecko with a proper diet and suitable living conditions will have a higher chance of surviving longer without food than a sick or weak gecko. Provide your gecko with a balanced diet and a clean environment to optimize its health.


Metabolic rate varies among leopard geckos, with younger geckos having faster rates than older ones. This factor influences how often your gecko needs to eat.

A higher metabolic rate means your gecko requires more frequent feedings, while a lower metabolic rate will allow them to go long periods without food.

Understanding these factors helps you tailor your care routine to suit your leopard gecko’s needs. Keep an eye on its age, health, and metabolism, and make any necessary adjustments to ensure good health during periods without food.

Potential Reasons For Food Refusal

Physical Factors

Stress can heavily impact your leopard gecko’s appetite. When your pet is stressed, it might refuse to eat. Common stress causes in leopard geckos include a new home, shedding, or dealing with illness or injury.

Additionally, your leopard gecko might refuse to eat because it’s sick. Their health could be negatively affected by parasites, dehydration, or diseases like metabolic bone disease or impaction.

It’s important to monitor your gecko for symptoms of such problems to ensure they get the proper care they need.

Some geckos might struggle with vision problems that make it difficult for them to hunt and eat. In this case, consult a veterinarian to determine the best action to improve its sight and overall health.

Environmental Factors

Temperature plays a significant role in your leopard gecko’s appetite. Geckos cannot properly digest their food in lower temperatures.

Maintaining the proper temperature gradient in their enclosure is essential. Too high temperatures can lead to dehydration and make it dangerous for your gecko.

Another factor that may cause your leopard gecko to refuse food is an inadequate or stressful environment. Having a comfortable and clean living space is crucial for your pet. Ensure their enclosure has the appropriate hideaways, clean substrate, and a sanitary, safe environment.

Diet plays a big part in how your gecko feels and eats. Offering them a proper and varied diet helps maintain their health, but overfeeding or exclusively offering tempting treats like waxworms can also lead to a refusal to eat a balanced diet.

It’s worth noting that your leopard gecko may have a specific reason for refusing food. For example, brumation in adult geckos can lead to periods of fasting, while females may refuse food during ovulation. Consider these factors when understanding and addressing your gecko’s feeding habits.

Diet and Feeding Tips

When caring for your leopard gecko, it’s essential to understand its dietary needs and follow a proper feeding schedule. This section will cover feeding schedules, choosing suitable food, and transitioning your gecko to new food.

Feeding Schedule

Young leopard geckos under 6 months old must be fed daily. As they get older, feeding frequency will decrease.

Sub-adult leopard geckos (6-12 months of age) can be fed every other day, while adult leopard geckos (over 12 months of age) can be fed every two to three days.

Adult leopard geckos can go 14 days to over 1 month without food.

Choosing Suitable Food

Leopard geckos are insectivores and require a diet consisting of a variety of insects to meet their nutritional needs. Some insects you can offer include:

  • Mealworms
  • Crickets
  • Waxworms (in moderation, as they can be high in fat)
  • Dubia roaches

Providing a calcium supplement is essential to ensure your gecko receives adequate calcium. You can dust the insects with a calcium powder or offer a small dish of calcium powder in the enclosure for your gecko to lick.

Transitioning to New Food

Leopard geckos can sometimes be picky eaters. When you need to introduce your gecko to a new food, it’s crucial to do so gradually. Start by offering a small number of the new insects alongside its current food.

Over time, increase the number of new insects while reducing the number of familiar insects until the transition is complete.

If your gecko is hesitant at first, don’t be discouraged. Simply stay patient and consistent, and your leopard gecko will eventually adjust to the new food source.

Signs Your Leopard Gecko May Need Veterinary Help

While leopard geckos are quite hardy and can go without food for some time, it’s crucial to keep an eye on their health. In this section, we’ll discuss some signs that may indicate your leopard gecko needs veterinary attention.

Weight Loss

Although they can go without food for extended periods, if your leopard gecko starts losing weight rapidly, it’s time for a checkup. Weight loss may indicate underlying health problems like metabolic bone disease or dehydration. Regular weigh-ins can help you monitor your gecko’s weight and ensure they’re maintaining a healthy size.

Lethargic Behavior

Leopard geckos are naturally nocturnal, but they should still be fairly active when they’re awake.

If your gecko is consistently lethargic or has trouble moving, it could be a sign of an issue like metabolic bone disease or even a respiratory infection. Provide an optimal environment, including proper lighting and heat, to support their overall well-being and consult a vet if you see any changes in their behavior.

Digestive Issues

Leopard geckos can sometimes experience digestive problems like fecal impaction, which may result from improper feeding or an inadequate diet. If your gecko is straining during defecation, has stopped passing waste altogether, or seems to be in pain, it’s essential to consult a vet for appropriate care.

A professional can help diagnose and treat any digestive issues and provide guidance on how to prevent them.

Besides the signs mentioned above, regular checkups with a qualified reptile veterinarian can ensure your leopard gecko remains in good health.

Remember, an ounce of prevention is worth a pound of cure, and by keeping a close eye on your gecko’s health, you can save them from unnecessary suffering and potentially life-threatening issues.

Caring For a Sick or Stressed Leopard Gecko

When your leopard gecko is sick or stressed, their appetite may decrease. Ensuring they remain comfortable and addressing any underlying health conditions is imperative.

Keeping Your Gecko Comfortable

Provide a warm and humid environment for your gecko, as this helps aid digestion and overall well-being.

Replace any sand or loose substrate with a safer option like paper towels or reptile carpet to prevent impaction. Keep their habitat clean, and ensure they always have fresh water available.

Offer a warm bath in shallow water for your leopard gecko to help keep them hydrated and assist with shedding issues. Monitor the temperature of their enclosure with a thermometer and adjust the heat bulb as necessary to maintain the proper gradient.

Addressing Health Conditions

Adjust your leopard gecko’s feeding schedule based on its age and health status. Healthy adult leopard geckos can skip several days between feedings, but a sick gecko may require more frequent, smaller meals.

Offer easy-to-digest insects like dubia roaches instead of crickets, and remove uneaten insects after 10 to 15 minutes to prevent stress.

Watch for signs of weight loss or lethargy, and consult an experienced reptile veterinarian if your gecko’s condition worsens or does not improve.

It’s important to act quickly as leopard geckos may need specific supplements or treatments for various health conditions, such as vitamin deficiencies, infections, parasites, or metabolic bone disease.

When your gecko’s health improves, gradually reintroduce it to a regular feeding schedule. During breeding season or winter months, its appetite may naturally decrease. Always monitor your gecko’s overall well-being and adjust your care accordingly.
