Hey there, fellow gecko enthusiasts! If you’ve ever wondered how to fatten up a skinny leopard gecko, you’ve come to the right place.

Maintaining a healthy weight for these little reptiles is essential, as it directly affects their overall well-being.

In this blog post, we’ll dive into the possible reasons behind a skinny leopard gecko and share tips on how to help them gain weight.

Fun Fact #1: Did you know leopard geckos can store fat in their tails? This not only serves as a backup energy source but also helps them maintain good health!

Identifying a Skinny Leopard Gecko

Before we dive into fattening up your little friend, let’s first figure out if your leopard gecko is indeed skinny. Some signs and symptoms to look for include:

  • A thin, underdeveloped tail
  • Visible hip bones or spine
  • Low energy levels or lethargy
  • Loss of appetite or difficulty eating

Why is my leopard gecko so skinny? There could be several reasons, such as:

  • Inadequate nutrition
  • Parasites or illness
  • Stress from their environment
  • Improper temperature or lighting conditions

If you suspect your leopard gecko is underweight, it’s crucial to address the issue right away. The following sections will guide you through the steps to help your gecko gain weight and improve their overall health.

Fun Fact #2: Leopard geckos are one of the few gecko species with eyelids, which help them blink and keep their eyes clean!

How to Fatten Up A Skinny Leopard Gecko

Here are the seven (7) ways to do so.

One of the main factors in helping your leopard gecko gain weight is providing a well-rounded, nutritious diet.

1. Staple insects for a balanced diet

Offer a variety of insects, such as crickets, mealworms, and dubia roaches. These insects provide essential nutrients for your gecko’s growth and development.

2. Nutrient-packed treats

Offer treats like waxworms and hornworms occasionally. These insects are high in fat and can help your gecko gain weight quickly. However, use them sparingly as they can be addictive and lead to obesity if fed too often.

3. Gut-loading and dusting insects

Before feeding insects to your gecko, “gut-load” them by providing a nutritious diet for the insects themselves. This ensures your gecko receives essential vitamins and minerals.

Additionally, dust insects with calcium and vitamin D3 supplements to support your gecko’s bone health.

4. Importance of hydration

Don’t forget about water! Provide fresh water daily in a shallow dish, ensuring it’s easily accessible for your gecko.

5. Proper temperatures and gradients:

Creating the perfect environment for your leopard gecko is crucial for their well-being and can significantly impact their appetite and ability to gain weight.

Leopard geckos need a temperature gradient in their enclosure, with a warm side around 88-90°F (31-32°C) and a cool side around 75-78°F (24-26°C).

A heat mat or heat lamp can help maintain these temperatures. Proper temperature regulation allows your gecko to digest food more effectively and maintain a healthy weight.

6. Safe and comfortable hiding spots

Leopard geckos require multiple hiding spots within their enclosure to feel secure. Include at least one hide on the warm side and one on the cool side.

Providing a safe environment can help reduce stress and promote a healthy appetite.

7. Clean and clutter-free environment

Maintain a clean habitat by removing uneaten food, waste, and shedding skin. Regularly replace the substrate and sanitize the enclosure to prevent bacterial growth.

Monitoring and Measuring Progress

As you work on fattening up your skinny leopard gecko, monitoring their progress and making adjustments as needed is essential. Here’s how you can do that:

Regular weigh-ins: Use a digital kitchen or reptile scale to weigh your gecko once a week. Track their weight to ensure they’re steadily gaining weight and making progress. If you don’t see any improvements after a few weeks, consider adjusting their diet or consulting a reptile veterinarian.

Adjusting the diet and environment as needed: If your gecko isn’t responding well to the changes, consider trying different insects or adjusting the temperature and humidity levels. Continuously observe your gecko’s behavior and make tweaks as necessary.

Recognizing signs of improvement: As your gecko gains weight, you should notice a fuller tail, increased energy levels, and improved appetite. These are all positive signs that your efforts are paying off!

When to Seek Professional Help

While following our guide should help your leopard gecko gain weight, there are instances when seeking professional help is necessary. Keep an eye out for the following:

Persistent weight loss despite efforts: If your gecko continues to lose weight or fails to gain weight despite implementing the recommended changes, it’s time to consult a qualified reptile veterinarian.

Possible underlying health issues: Weight loss or difficulty gaining weight can be symptoms of more serious health issues, such as parasites, metabolic bone disease, or infections. A reptile veterinarian can diagnose and treat these conditions to help your gecko regain their health.

Finding a qualified reptile veterinarian: Look for a veterinarian who specializes in reptiles or has experience treating leopard geckos. They’ll be better equipped to address your gecko’s specific needs and provide appropriate care.


Helping your skinny leopard gecko gain weight and maintain good health is crucial for their overall well-being.

By providing a nutritious diet, optimizing their habitat, monitoring their progress, and seeking professional help when needed, you’ll be well on your way to ensuring a happy and healthy life for your little reptile friend.

Remember, it’s essential to be patient and consistent with your efforts. With proper care and attention, your leopard gecko will thrive and live a long, fulfilling life.
