Heating and Lighting
Leopard geckos need belly heat to properly digest food.
The best way to heat your leopard gecko is by using an undertank heating pad or tape. These are available at any pet store or online. Heating one end of the cage is best. This allows for a temperature variation that your lizard needs. Heat rocks tend to become too hot for leopard geckos and should be avoided due to the risk of burns. For viewing, a simple low-wattage light can be placed overhead on the screen-cage top and left on 12 hours a day. Because leopard geckos are active at night (notice their vertical pupils), they do not need to bask under a special UVB light.
The ideal temperature in the hide box is 88 to 90 degrees Fahrenheit at all times. The ambient air temperature of the room they are housed in should be above 73 degrees.
