A long, low enclosure with a warm floor
Leopard geckos are ground-dwellers from dry, rocky country, so their first home should be a long, low terrarium — a three-foot enclosure gives an adult the temperature gradient it needs. Belly heat matters for digestion, so warm the floor at one end with a heat mat or overhead lamp controlled by a thermostat, holding the warm surface around 88–90°F. The cool end should fall to the mid-70s. Measure the floor itself with a digital thermometer or temperature gun, because a leopard gecko lives its whole life at floor level.
The three-hide rule
Arrange three hides across the gradient. The warm hide sits over the heat so the gecko can digest in safety. The cool hide anchors the far end. Between them goes the humid hide — a closed hide or lidded box with an entrance hole, lined with damp paper towel, sphagnum moss or coco fibre, kept moist so the steamy air inside loosens old skin at shedding time. A gecko that can complete a shed cleanly, right down to the toes, is a gecko whose humid hide is doing its job.
Flooring without the risk
For a first home, keep the floor simple and safe: paper towel, slate tile or a purpose-made solid liner. Loose sand is a poor choice for a new keeper's setup — a hunting gecko lunges at insects and can swallow substrate with the strike. Paper towel has a second advantage: droppings are obvious, so the gecko's health and appetite can be judged at a glance during the settling-in weeks. Add flat stones and a low branch for texture and climbing, kept stable so nothing can topple onto the gecko.
Water, calcium and the evening routine
Set a shallow water dish at the cool end and a bottle-cap-sized dish of plain calcium powder in the enclosure for free licking — leopard geckos regulate their own intake surprisingly well. This is a dusk-active animal, so plan feeding for the evening, when the gecko emerges to hunt insects. Keep light gentle during the day and let the enclosure go properly dark at night; a gecko kept under constant bright light will spend its life hiding from it.
Shared notes for a small animal
The details of this setup — which hide is the humid one, when the moss was last dampened, what the warm floor reads — are exactly the details that get lost between family members. Keep them on a profile everyone can see, alongside feeding and shed records. KinsLe's Family Sharing puts the gecko's temperatures, shed dates and setup notes in front of the whole household, so the humid hide gets re-dampened on schedule whoever is home.
