A leopard gecko thrives with a warm-to-cool temperature gradient, low humidity, live insects, and a moist hide for shedding.
Setting up a leopard gecko’s home correctly the first time is the difference between a healthy, active pet and one that develops health problems. These lizards are naturally hardy, but they depend on their keeper to recreate the arid conditions of their native habitat. The essentials come down to five things: the right enclosure, a proper heat gradient, controlled humidity, a shedding box, and a steady diet of live prey.
The Enclosure: Size, Ventilation, and Safety
Bigger is always better; a larger space gives the gecko room to explore and makes it easier to create a proper temperature gradient.
The enclosure should be secure enough to prevent escape, free of sharp hazards, and made from a solid material that is simple to clean. Glass terrariums with a mesh lid work well because they offer visibility, retain heat, and provide ventilation.
Temperature and Humidity: Getting the Gradient Right
Heat is the single most important factor in leopard gecko health.
Use an under-tank heater or a low-wattage ceramic heat emitter controlled by a thermostat. Never guess at temperatures; use a digital thermometer with a probe on both ends of the enclosure.
Humidity is the second critical number. Leopard geckos come from dry, rocky environments, and overly humid conditions can lead to respiratory issues and skin problems.
Feeding, Supplements, and Handling
Leopard geckos are insectivores and need live prey. Crickets, dubia roaches, and mealworms are the most common and reliable feeders. Insects should be gut-loaded (fed nutritious food) for 24 hours before offering them, then dusted with a calcium and vitamin supplement immediately before feeding.
Common Mistakes and the Moist Hide Setup
Most new keeper problems trace back to a few setup errors: an undersized enclosure, poor ventilation, no humid hide, or an incorrect temperature gradient. The humid hide is the one most often skipped, yet it is essential for a clean shed.
