Why Is My Leopard Gecko Not Shedding? 9 Possible Reasons

Leopard Gecko Shedding

A leopard gecko can have issues with shedding because of various factors that influence its overall health and living conditions. Shedding is a natural process for reptiles, allowing them to grow and remove old skin. When this process is interrupted or doesn’t occur as expected, it can be concerning for gecko enthusiasts and caretakers.

The reasons can range from potential health issues, incorrect temperature and humidity in their enclosure, to a deficient diet, and even specific stages in their life cycle, such as ovulation or brumation.

Key Takeaways:

Potential Health Issues: Leopard geckos can experience shedding problems due to health issues like liver disease, bacterial infections, and parasites. These can often be traced back to subpar living conditions or chronic malnutrition.

Enclosure Conditions: Maintaining the right temperature and humidity is vital. Humidity levels should be monitored with a hygrometer and kept around 40%, but never below 30%. Additionally, UVB lighting is crucial for Vitamin D and calcium synthesis in leopard geckos.

Diet Matters: Ensure a nutrient-rich diet to prevent shedding difficulties. Beneficial foods include crickets, Dubia roaches, mealworms, and superworms.

Brumation and Ovulation: Leopard geckos can halt or change their shedding cycles due to natural processes like brumation (reptilian hibernation) during winter months or ovulation in females.

Addressing Issues: If shedding problems arise, look for signs such as leftover dried skin or a lack of appetite. Assist the gecko by providing supplemental nutrients, ensuring a moist hide, and giving them a safe surface to rub against.

9 Possible Reasons Why a Leopard Gecko Is Not Shedding

Leopard Gecko Shedding

Shedding is a natural occurrence for leopard geckos, much like how snakes or other reptiles shed their skin. When your gecko isn’t shedding, it could be due to several factors that might be affecting its health or environment. It’s essential to consider multiple variables, from their diet and habitat conditions to inherent health issues.

Potential Health Issues

One of the prime concerns when a leopard gecko isn’t shedding properly is the presence of potential health issues. Like other animals, leopard geckos can suffer from a variety of health problems that directly impact their shedding process.

Some of the more common health challenges include liver disease, which can hinder their metabolic processes, and bacterial infections that affect their skin’s health.

Additionally, noticeable weight loss can be an alarming sign of underlying health concerns, further complicating the shedding process.

Parasites are another issue, often stemming from contaminated food sources or unsanitary living conditions, which can leach essential nutrients from the gecko, affecting their overall health.

Enclosure Might Not Have The Right Temperature and Humidity

An optimal environment plays a pivotal role in the well-being of a leopard gecko, especially when it comes to the shedding process.

Maintaining the right temperature and humidity levels in their enclosure is paramount. Leopard geckos, being ectothermic, rely on external sources for body heat, and when the temperature isn’t within the right range, it can disrupt their natural processes, including shedding.

The humidity level within the enclosure is another critical factor. Too dry, and the gecko can struggle to shed; too moist, and it can lead to other health concerns.

Using a hygrometer is an excellent way to monitor the humidity levels, ensuring they hover around 40 percent. It’s essential, though, to ensure it doesn’t drop below 30 percent, as that can cause the gecko’s skin to become too dry.

Furthermore, the introduction of UVB lighting can significantly benefit a leopard gecko’s health.

While they are nocturnal and don’t bask in the sun like other reptiles, a controlled amount of UVB can aid in providing Vitamin D, which is crucial for calcium synthesis.

This helps in bone health and, indirectly, in the shedding process by maintaining skin health.

Diet Doesn’t Provide The Right Nutrients

A nutrient-rich diet is at the heart of ensuring the overall health and well-being of leopard geckos.

When these reptiles don’t receive the necessary nutrients from their meals, they can face a plethora of challenges, including shedding difficulties and other severe health problems. Just as humans need a balanced diet for optimal function, leopard geckos require specific nutrients to flourish.

Diving into the foods that are beneficial for leopard geckos, it’s evident that variety is the key. Crickets are a staple, known for being protein-rich and easy for geckos to hunt, imitating their natural predatory behavior.

Dubia roaches are another nutrient-packed option, providing essential fats. Meanwhile, mealworms and superworms not only offer nutrition but also help in enhancing the gecko’s hunting skills.

Stunted Development

Stunted development in leopard geckos is a concerning sign, indicating that the reptile isn’t growing or thriving as it should. Several factors can contribute to this condition. One of the primary culprits is a poor diet.

Without the right nutrients, leopard geckos can’t develop properly, much like how a plant struggles without adequate sunlight. Additionally, an inadequate living environment, where the gecko’s enclosure isn’t set up correctly or maintained well, can hinder their growth.

Another factor that many might not consider immediately is the practice of housing multiple geckos together.

This can lead to competition for resources, causing undue stress. The continuous stress from such situations, especially if there’s bullying among geckos, can be detrimental. It’s not just about physical confrontations; the persistent tension in the environment can affect their appetite, sleep, and overall well-being, leading to stunted growth.

Because of Injury

Injuries can play a significant role in a leopard gecko’s shedding process. A leopard gecko might experience difficulties with shedding when injured, and the root causes of these injuries can vary widely.

One common source of injury is bullying from other geckos, especially when housed together. Dominant geckos might nip or bite, leading to cuts and wounds.

Another often overlooked source of injury is sharp tank decor. While it’s tempting to make a gecko’s environment visually appealing, it’s crucial to ensure that all items inside their habitat are safe.

Sharp edges or poorly placed decorations can lead to cuts or abrasions, especially if the gecko rubs against them during the shedding process.

Some of the more common injuries leopard geckos can sustain include cuts, burns from improperly managed heat sources, and impaction from ingesting substrate or decor.

Each of these injuries can introduce stress into the gecko’s life, which in turn can negatively impact their appetite and natural shedding process. Stress and pain can divert their energy and focus, making shedding even more challenging.


When considering the shedding patterns of female leopard geckos, it’s essential to account for the natural phenomenon of ovulation. Just like in many other creatures, female leopard geckos have a reproductive cycle where they can produce eggs.

These eggs can either be fertilized or remain unfertilized. Intriguingly, ovulation can influence their shedding cycle, sometimes leading to variations or inconsistencies in their regular shedding behavior.

Typically, ovulation in leopard geckos occurs during the early spring to summer months. During this period, you might observe behaviors that closely resemble those of shedding issues.

For instance, a gecko might appear more lethargic than usual, or they might seem to be struggling with shedding. This lethargy and altered behavior are primarily due to the energy-intensive process of producing eggs.


Brumation is a unique and natural phenomenon that occurs in the lives of many reptiles, including leopard geckos. Drawing parallels to what many might understand as hibernation in mammals, brumation is effectively a form of reptilian hibernation. The purpose of this behavior is rooted in energy conservation.

During the colder winter months, as temperatures drop and food becomes scarce, leopard geckos, like other reptiles, go into a state of reduced activity to conserve their vital energy.

While in this brumation state, leopard geckos become notably inactive. Their metabolic processes slow down, and many of their regular behaviors, such as eating and moving, diminish considerably.

This inactivity extends to their shedding cycles as well. As the gecko’s body focuses on conserving energy, the regularity of its shedding can be paused or delayed.

Tail Loss

Tail loss is an intriguing and somewhat unsettling aspect of leopard gecko biology for many new owners. Known scientifically as autotomy, this phenomenon allows the gecko to detach its tail as a survival mechanism.

In the wild, when a predator grabs onto a leopard gecko’s tail, the gecko can release it, creating a distraction and granting it a chance to escape. This tail, once detached, will twitch and wriggle for a while, drawing the predator’s attention and buying the gecko precious time.

Post tail loss, leopard geckos have the remarkable capability to regrow their tails. This regrowth process, however, is not instantaneous. It takes time, with the new tail often appearing stumpier and less streamlined than the original.

One of the factors that can unintentionally lead to tail loss is handling. If a gecko is not accustomed to being handled or if it’s handled roughly, it might drop its tail out of stress or fear. Therefore, gentle and infrequent handling, especially when the gecko is new to its environment, can help in preventing tail loss.

As a prevention tip, always approach a leopard gecko from the front, ensuring it can see you, and avoid grabbing its tail.

Metabolic Bone Disease (MBD)

Metabolic Bone Disease (MBD) is a condition that unfortunately afflicts many captive leopard geckos. It arises primarily from an insufficient intake of calcium and inadequate exposure to UVB lighting. While leopard geckos, being nocturnal, do not necessarily require UVB for survival, it does aid in their metabolism of calcium, a critical element for their bone health.

Symptoms of MBD can be distressing to witness. A gecko suffering from this ailment may show a decreased or complete loss of appetite. They may exhibit signs of weakness and appear noticeably lethargic. In severe cases, this disease can cripple the reptile, leading to difficulty in movement or even potential immobility. Their bones may become frail and easily breakable, and deformities can manifest, such as kinks in the spine or limbs.

To prevent Metabolic Bone Disease, there are several key steps a gecko owner should follow:

Calcium Supplementation: Ensure that the gecko’s diet is regularly dusted with a quality calcium supplement, especially if it primarily consumes insects. Many insects are deficient in calcium, so supplementation is crucial.

Vitamin D: While calcium is vital, it’s the synergy of calcium with vitamin D that ensures proper absorption and utilization. Therefore, using a multivitamin supplement with vitamin D3 is recommended.

Optimal Tank Temperatures: Ensure that the tank has a proper temperature gradient. The warmer end aids in digestion and the metabolism of essential nutrients.

Consider UVB Lighting: Even though it’s not a strict necessity, providing UVB lighting can be beneficial, especially in cases where the gecko may not be getting enough dietary vitamin D3.

What Are the Signs of Problems With Shedding?

Shedding is a natural process for reptiles, including leopard geckos. However, sometimes this process doesn’t go as smoothly as it should, potentially indicating health concerns. Here are some of the signs of problems with shedding:

Leftover Dried Skin: One of the most visible signs of shedding issues is remnants of dried skin still clinging to the gecko after most of the shedding has occurred. While it’s common for small areas, like toes or the tail tip, to retain some skin, larger patches indicate an incomplete shed.

Excessive Movement and Restlessness: If your gecko is continuously moving around the enclosure, trying to rub against various surfaces, it might be attempting to remove skin that hasn’t shed properly. While some movement is normal, excessive activity can be a cause for concern.

Rubbing on Surfaces: Leopard geckos might rub their bodies against rough surfaces in their enclosure to aid the shedding process. However, if they are doing this excessively, it could indicate trouble getting rid of old skin.

Lack of Appetite or Interest in Activity: A gecko that’s having difficulty shedding might also lose interest in food or its usual activities. If the shedding problem persists, the gecko might become less active, show a decline in appetite, or even stop eating altogether.

How to Help a Leopard Gecko with Shedding Issues

Every leopard gecko owner wants to ensure that their pet experiences a smooth and healthy shedding process. Understanding the shedding process and being aware of potential complications is vital to achieve this. Shedding is not just a fascinating natural process but is also an essential aspect of a gecko’s growth and health maintenance. If complications arise, they can lead to health issues and discomfort for the gecko.

To minimize complications and promote healthy shedding, consider the following recommendations:

Supplement the Diet: Ensuring your leopard gecko receives a nutrient-rich diet is crucial. The right nutrients not only aid in the shedding process but also boost the overall health of the gecko. Supplementing the gecko’s diet with essential vitamins and minerals can make a significant difference. For instance, calcium plays a key role in maintaining healthy skin, which in turn aids in the shedding process.

Maintain the Moist Hide: One of the essential parts of a leopard gecko’s enclosure is the moist hide. This humid spot aids in the shedding process by providing a microenvironment where the gecko can go to help loosen the old skin. Ensure this hide remains clean and adequately moist. Use safe substrates, like damp paper towels or moss, and check regularly to maintain the right moisture levels.

Provide Safe Rubbing Surfaces: Leopard geckos naturally seek out rough surfaces to help rub off old skin during the shedding process. By providing a rough yet safe decoration piece or surface inside the enclosure, you offer them a controlled space to assist with their shedding. Make sure that these surfaces do not have any sharp or pointy edges that might cause injuries.
