Leopard gecko care guide:
Leopard geckos (Eublepharis macularius) are native to South Central Asia and are popular pets due to their small size, docile nature, and ease of care. In the wild, they inhabit rocky, arid regions and are nocturnal, so they are well-adapted to living in a controlled environment in captivity.
Natural history: Leopard geckos are insectivorous and primarily eat insects in the wild. They are known for their ability to shed their tail as a defense mechanism, which will regenerate over time. Leopard geckos are generally slow-moving and docile, making them a good choice for beginner reptile owners.
Proper housing: A 20-gallon long vivarium is the minimum recommended size for an adult leopard gecko. A wooden or glass vivarium is ideal. Unlike some lizards that need different-sized tanks as they grow, many owners choose to start their baby and juvenile geckos in the same tank that adults use. It is important to provide your leopard gecko with a substrate, such as reptile carpet or paper towels, and to include hiding spots, a water dish, and a basking area in the enclosure.
Lighting and temperature: Leopard geckos do not require UVB lighting, but it is important to provide a heat source, such as a heat pad (outside tank) or better is an overhead heat lamp, to maintain a temperature gradient in the enclosure. The cool end of the enclosure should be around 75-80 degrees Fahrenheit, while the warm end should be around 90-95 degrees Fahrenheit. Leopard geckos are nocturnal, so it is not necessary to provide a day/night cycle, but it is important to maintain consistent temperature and lighting conditions.
Humidity: Leopard geckos are desert-dwelling species, so they do not need a highly humid environment to live comfortably. The ideal humidity level for leopard geckos is around 30-40%. A moist hide box should be provided to aid in shedding
Common medical concerns: Leopard geckos can be affected by a variety of medical conditions, including metabolic bone disease, respiratory infections, intestinal parasites, and skin infections. It is important to monitor your leopard gecko for any signs of illness
Vitamin A is an essential nutrient for leopard geckos, as it plays a critical role in various bodily functions such as vision, growth, and immune system function. Leopard geckos with vitamin A deficiency may exhibit symptoms such as irregular shedding, hyperkeratosis of the eyes, fertility issues, sudden weight loss, and inactivity. To prevent vitamin A deficiency, it is important to provide your leopard gecko with a diet that includes sources of vitamin A, such as leafy greens, and to use multivitamin supplements as directed.
It is also important to provide pure calcium enriched with vitamin D, as vitamin D helps the body absorb calcium and promotes proper bone development. The frequency of vitamin supplementation will depend on the life stage of your leopard gecko, so it is important to consult with a veterinarian experienced in reptile care to determine the appropriate vitamin schedule for your pet.
We recommend the use of Repashy calcium plus for geckos. Repashy SuperCal Plus is a calcium supplement designed specifically for reptiles, including geckos. This product is formulated with high levels of vitamin D to support the absorption of calcium and promote proper bone development in species that receive little UVB radiation from natural or artificial sunlight. 
To use Repashy SuperCal Plus, mix the recommended amount with water according to the package instructions and offer it to your gecko in a separate dish. It is recommended to dust insects with the supplement before feeding them to your gecko to ensure that they are receiving the necessary nutrients. Repashy SuperCal Plus should be used in conjunction with a well-rounded diet and other necessary supplements, as directed by a veterinarian experienced in reptile care.
Some potential benefits of using Repashy SuperCal Plus include:
Improved bone health: Calcium is essential for proper bone development and maintenance, and the high levels of vitamin D in this product can help support the absorption of calcium.
Support for immune system function: Vitamin D plays a role in immune system function, and adequate levels of this nutrient can help support overall health in geckos.
Ease of use: Repashy SuperCal Plus is easy to provide in a small dish
