Availability
Captive-bred leopard geckos can be found in pet stores, at reptile shows and on the Internet. Many breeders have websites where you can learn about, select and purchase healthy leopards.

There is a huge collector market worldwide for the rarer variations of leopard geckos.
 

Size
Hatchlings measure 3 to 4 inches long. Adult females are typically 7 to 8 inches, and males are 8 to 10 inches. Some males of the giant bloodlines reach nearly a foot.
Life Span
Leopard geckos are long-lived compared to some reptiles. On average you can expect your gecko to live six to 10 years, but many males live 10 to 20 years. At least one male is still breeding at 28 years of age in my colony.

Caging
A 10- to 20-gallon aquarium houses one or two leopard geckos from hatchling to adult size. Larger tanks tend to cause the geckos to stray away from their proper heat and hide box. Although visibility is reduced, many people use plastic storage boxes as housing. Any cage you choose should be at least 1 foot tall. Be sure to have a secure screen top on your gecko cage that will support a light fixture, provide good ventilation and keep out bothersome cats.

A hide box filled with moist moss or vermiculite is needed, so your leopard gecko can shed its skin properly. This secure setting also is needed for egg laying if you plan on breeding geckos.

Live or artificial plants can be added for a nice decorative touch.
 

Lighting and Temperature
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.

Albino leopard geckos are light-sensitive for the first few months of their lives, but they do fine as a pet.

The ideal temperature in the hide box is 86 to 90 degrees Fahrenheit at all times. The ambient air temperature of the room they are housed in should be above 73 degrees.

Substrate
Newspaper, pea gravel, artificial turf, flat stones or no floor covering are OK. A young or debilitated leopard gecko might consume sand or fine-particle products on the cage floor, and this could lead to intestinal impaction.

Leopard geckos actually have a "bathroom" in one corner of their cages, and that area can be spot-cleaned without disrupting the entire system.

Do not expose your gecko to commercial plant soils or sands that may contain fertilizer or pesticides.

Food
Live insects are a must for your gecko; they do not eat plants or veggies. The best items to use are mealworms or crickets, but you can treat your pet to waxworms or superworms once a week if you wish. We have used regular mealworms (Tenebrio molitor) without health issues for since 1978. Avoid feeding leopard geckos pinky mice.

All insects must be first given a nutritious powdered diet for at least 12 hours before being fed to your leopard gecko. This process is called “gut loading,” and it is very important to the health of your pet. Chick or hog mash is available at all feed stores, and several good commercial diets are available for this purpose, as well. Simply place the insects in a tub of gut-load diet with a piece of potato to serve as a source of water.

Dusting your insects is one way to deliver important vitamins and minerals to your leopard gecko. Insects and the dusting powder can be placed in a plastic bag or deep tin can, and shook gently to coat the insects’ bodies. When adding the dusted insects to the cage, be sure not to let the powder get into a gecko’s eyes.

Another way to give the extra powdered supplements to your gecko is to keep a small jar lid filled with vitamin-mineral powder at all times. The gecko knows how much its body needs, and it will lick up the powder accordingly.

Keepers can offer two appropriately sized insects for every inch of a leopard gecko’s total length. A meal every other day is fine. Therefore, a 4-inch-long gecko would receive eight mealworms three to four times a week
It is normal for leopard geckos to eat their shed skin.

Water
A shallow water dish with fresh water must be available at all times. It should also be stable, so it cannot be spilled. Cage substrate should be kept dry, so be careful about spillage. Make sure that young and adult leopard geckos can climb easily out of the dish you use. Vitamin drops should not be added to the water.
