Mack Snow Leopard Geckos are a fascinating morph of the common Leopard Gecko, known for their striking icy coloration and unique patterns. Originally hailing from the arid regions of Afghanistan, Pakistan, and Northwest India, these small reptiles have now become popular pets for reptile enthusiasts around the world.

These captivating creatures exhibit an array of physical features, including white or pale yellow body coloration with dark spots, as well as a variety of genetic traits. When it comes to caring for a Mack Snow Leopard Gecko, diet, enclosure maintenance, and attention to their health concerns are important factors to ensure their well-being. As captivating as they are in appearance, it’s essential to understand their specific needs and characteristics before welcoming one into your home.


Mack Snow Leopard Geckos are a distinctive variation of the Leopard Gecko (Eublepharis macularius). Their unique appearance can be credited to the efforts of reptile breeders John and Amy Mack. The couple, founders of Reptiles by Mack, were looking to create an intriguing gecko breed that would captivate herpetology enthusiasts and collectors.

In their breeding pursuits, they noticed some hatchlings displaying a “snow-like” coloration, which significantly differed from the typical appearance of Leopard Geckos. John and Amy continued to work with these hatchlings, breeding them back to each other in the following season. As a result, they successfully produced Super Snows, Mack Snows, and normal Leopard Geckos.

The Mack Snow Leopard Gecko is now recognized as an incomplete dominant trait within the Leopard Gecko community. This means that the Mack Snow trait can be combined with other morphs to create various unique variations. With their strikingly pale coloration and co-dominant genetic trait, Mack Snow Leopard Geckos are a popular choice for collectors and reptile enthusiasts alike.

Physical Characteristics

Mack Snow Leopard Geckos are known for their unique coloring, which sets them apart from most other gecko species. Let’s take a closer look at their physical characteristics:

  • Coloration: The base colors of a Mack Snow Leopard Gecko can range from white to light yellow and tan. They have black spots scattered across their bodies, adding to their distinct appearance.
  • Size: As hatchlings, they are quite small, but as they grow and reach adulthood, they develop into a considerably larger size. Adult females generally measure between 18 and 20 cm, while adult males can reach 20 to 28 cm in length.
  • Weight: Once fully grown, a Mack Snow Leopard Gecko typically weighs around 80 grams.

In summary, the physical characteristics of the Mack Snow Leopard Gecko are mainly defined by its unique coloring, varying shades of white, yellow, and tan, along with black spots. Its size and weight as an adult also vary depending on its sex, with males usually being larger than females.

Genetic Traits

As a prospective owner of a Mack Snow Leopard Gecko, understanding the genetic traits of this species is essential. Your Mack Snow Leopard Gecko’s distinctive characteristics result from different morphs and genetics patterns.

  • Mack Snow (incomplete dominant): The Mack Snow morph is an incomplete dominant gene. This means that both genes for a specific characteristic, such as the typical Leopard Gecko coloring and the snowy, pale coloration, can be present and visible in your pet. When two copies of the Mack Snow gene are inherited, a Super Snow morph is produced.

  • Albino (recessive): Albino Leopard Geckos carry a recessive gene. An offspring only shows albino traits if it inherits the gene from both parents. There are three primary strains of albino genes: Bell Albino, Rainwater Albino, and Tremper Albino.

  • Heterozygous and Homozygous: These terms refer to which versions of a gene an animal carries. Heterozygous animals carry one copy of the gene, while homozygous animals carry two identical copies. Homozygous animals are more likely to pass on the traits to their offspring.

  • Co-dominant traits: Co-dominant traits can be passed on by either one or both parents and are visible in the first generation of offspring. When both parents pass on the trait, it yields a “Super” form.

  • Wild type: The wild type is the most common and natural genetic trait found in a species. In the Leopard Gecko world, the wild type is represented by the typical pattern and coloration.

By understanding these genetic traits and patterns, you can appreciate the uniqueness of your Mack Snow Leopard Gecko. Using this knowledge, you can also predict possible outcomes in breeding, resulting in a wide range of morph combinations.

Diet and Feeding Requirements

As a Mack Snow Leopard Gecko owner, it’s essential to provide your pet with a proper diet to ensure its health and longevity.

Main diet: Mack Snow Leopard Geckos are insectivorous, meaning they primarily eat live insects. Some popular choices of insects include:

  • Crickets: A staple in gecko diets due to their accessibility and nutritional value.
  • Mealworms: Another commonly fed insect, rich in protein and easy to store.
  • Superworms: Larger and more nutritious than mealworms, but should be fed sparingly due to their higher fat content.

It’s important to provide a variety of insects to maintain a balanced diet.

Gut-loading: To further enhance the nutritional value of the insects, you should gut-load them. Gut-loading means feeding the insects a nutritious diet before offering them to your gecko. This ensures your gecko gets the essential nutrients it needs.

Feeding frequency: Young geckos require feeding daily, while adult geckos can be fed every other day. Adjust the amount of food according to the size and age of your gecko. Typically, offer as many insects as your gecko can eat within 10-15 minutes.

Supplements: Dust the insects with calcium and vitamin D3 supplements to maintain strong bones and prevent metabolic bone disease. Make sure to follow the supplement manufacturer’s instructions for the correct dosage and frequency.

Remember, a well-rounded and proper diet is crucial for the health and well-being of your Mack Snow Leopard Gecko. By following these guidelines, you’ll be able to provide the best possible nutrition for your pet.
