What Is Considered Underweight for A Leopard Gecko


When it comes to leopard geckos, maintaining a healthy weight is crucial for their overall well-being. Determining what is considered underweight for a leopard gecko involves understanding the species’ typical body condition.


Generally, a healthy adult leopard gecko should have a plump tail and a well-rounded body. If you notice that your gecko’s tail appears thin or bony, or if its body lacks the expected plumpness, it may be considered underweight.


Concerning their weight, a leopard gecko normally weights between 45 to 90 grams. So, if you weight your gecko with a digital kitchen scale and it weights below this, then it is underweight.


Potential Causes of Underweight In Leopard Geckos


There are several factors that can contribute to an underweight condition in leopard geckos. Understanding these potential causes can help you address the underlying issues and provide appropriate care.


Some common reasons why a leopard gecko may become underweight are:


1. Inadequate Diet

Leopard geckos require a balanced diet consisting of proper feeder insects and supplements. If they are not receiving adequate nutrition or if their diet lacks variety, it can lead to weight loss.


2. Parasites

Internal parasites, such as worms, can negatively affect a gecko’s ability to absorb nutrients from its food, leading to weight loss over time. Parasites may be acquired from contaminated food, substrate, or even from other reptiles.


3. Illness or Disease

Underlying health issues, such as metabolic bone disease, respiratory infections, or gastrointestinal disorders, can cause a gecko to lose weight. These conditions often require veterinary intervention to properly diagnose and treat.


4. Environmental Factors

Inappropriate temperature and humidity levels in the gecko’s enclosure can impact their metabolism and appetite, leading to weight loss. It’s essential to provide a suitable environment that mimics their natural habitat.

Signs and Symptoms of an Underweight Leopard Gecko


Recognizing the signs and symptoms of an underweight leopard gecko is crucial in identifying and addressing the issue promptly.


The common indicators to look out for are:


  1. Visible Rib Cage and Spine: When a leopard gecko is underweight, its rib cage and spine may become more pronounced and easily visible.
  2. Sunken Appearance: An underweight gecko may have a sunken or hollow appearance, particularly in the areas around its hips and tail base.
  3. Lack of Appetite: A gecko that is not consuming its usual amount of food or is completely refusing to eat may be experiencing weight loss.
  4. Reduced Energy and Activity Levels: Underweight geckos often exhibit decreased energy levels and may become lethargic or less active than usual.
  5. Changes in Skin and Shedding: Poor body condition can affect the gecko’s skin health, leading to difficulty shedding or skin that appears dull, dry, or wrinkled.

When it comes to feeding an underweight leopard gecko, offering a variety of suitable feeder insects is crucial.


Below are some feeder insects that are suitable for leopard geckos:


  • Crickets: Crickets are a popular staple feeder insect for leopard geckos. They are readily available, easy to find, and provide a good source of protein.


  • Mealworms: Mealworms are another common feeder insect that can be offered to underweight leopard geckos. They are high in fat and can help increase calorie intake.


  • Dubia Roaches: Dubia roaches are highly nutritious and have a favorable calcium-to-phosphorus ratio. They are an excellent choice for underweight geckos due to their high protein content.


  • Silkworms: Silkworms are a soft-bodied feeder insect that is rich in protein and low in fat. They are easy to digest and provide a good nutritional boost for underweight geckos.

Also, when it comes to feeding an underweight leopard gecko, it’s important to offer feeder insects that are high in nutrition to help promote weight gain.

These insects include:


  • Dubia Roaches: Dubia roaches are an excellent choice due to their high protein content, favorable calcium-to-phosphorus ratio, and low fat content.


  • Silkworms: Silkworms are highly nutritious, rich in protein, and contain essential amino acids necessary for gecko health.


  • Black Soldier Fly Larvae: Black soldier fly larvae, also known as Phoenix worms or calciworms, are high in calcium and protein, making them an excellent choice for underweight geckos.

Significance of Variety In The Diet Of An Underweight Leopard Gecko


Offering a variety of feeder insects is essential for the diet of an underweight leopard gecko. Feeding a diverse range of insects helps ensure that the gecko receives a wide spectrum of nutrients. Variety also helps stimulate the gecko’s appetite and prevents them from becoming selective eaters.


By providing a varied diet, you can offer different sources of protein, fats, vitamins, and minerals, ensuring your underweight gecko receives a well-rounded and balanced nutrition. Rotating between different feeder insects not only helps meet their nutritional needs but also adds enrichment to their feeding routine.


Supplementing an Underweight Leopard Gecko with Calcium and Vitamin


Supplementing the diet of an underweight leopard gecko with calcium and vitamin supplements is crucial to support their overall health and aid in weight gain.


Calcium is particularly important for leopard geckos as they require it for proper bone growth and maintenance. It helps prevent metabolic bone disease, a condition that can lead to weak bones, fractures, and other health issues. Calcium supplementation ensures that the gecko receives an adequate amount of this essential mineral.


Vitamin D3 is necessary for calcium absorption and utilization. It aids in the gecko’s ability to metabolize and utilize calcium effectively. Vitamin D3 is typically obtained through exposure to appropriate levels of UVB light or through dietary supplementation.


Leopard geckos also require other essential vitamins, such as vitamin A and vitamin E, to support their immune system, vision, and overall well-being. These vitamins are often included in commercial reptile supplements.


Proper Supplementation Techniques for Leopard Geckos


Proper supplementation techniques are vital to ensure that underweight leopard geckos receive the appropriate amount of calcium and vitamins.


Some of the key consideration to make include:


1. Calcium Supplementation

 Dusting feeder insects with calcium powder is a common method of calcium supplementation. Place the feeder insects in a plastic bag or container, add a small amount of calcium powder, and gently shake or toss them to coat them evenly. Offer the dusted insects to your gecko.


2. Vitamin Supplementation

Vitamin supplements can be used sparingly and should be chosen based on the specific needs of your underweight gecko. Follow the manufacturer’s instructions regarding dosage and frequency. Some vitamin supplements may be in the form of liquid drops or powders, which can be added to food or water as directed.


3. Balancing Calcium and Vitamin D3

 It’s important to strike a balance between calcium and vitamin D3 supplementation. Leopard geckos require both, but excessive vitamin D3 supplementation without sufficient calcium can lead to health issues. Use calcium supplements without added vitamin D3 at every feeding and those with added vitamin D3 two to three times a month.

Tips for Encouraging an Underweight Leopard Gecko to Eat


Encouraging an underweight leopard gecko to eat can be a challenge, but with some practical tips, you can help stimulate their appetite and promote healthy eating habits. Here are some strategies to consider:


  1. Offer Live Feeder Insects: Leopard geckos are natural hunters, and the movement of live feeder insects can entice them to eat. Use tongs or tweezers to dangle the insect in front of the gecko, mimicking natural prey behavior.
  2. Try Different Feeder Insects: If your gecko is not showing interest in the current feeder insects, try offering a variety of options. Some geckos may prefer certain insects over others, so experimenting with different types can help stimulate their appetite.
  3. Enhance Food Aroma: Some leopard geckos are more responsive to food with strong smells. You can try lightly dusting the feeder insects with a calcium powder that has a strong scent or even lightly misting them with water to increase their appeal.
  4. Offer Food at Optimal Temperatures: Leopard geckos are more likely to eat when the food is at the right temperature. Ensure that the feeder insects are at room temperature or slightly warmed before offering them to the gecko.
  5. Provide a Quiet Feeding Area: Creating a calm and quiet environment during feeding time can help reduce stress and distractions. Find a quiet spot where the gecko feels secure to encourage feeding.
