Leopard Gecko

People love leopard geckos for their small size, spotted skin, blinking eyelids and a calm, slow way of moving that makes them one of the easiest lizards to hold; LafeberVet calls them lizards that make excellent pets. They live happily in a 10-20 gallon tank with a warm hide and a moist hide, eat gut-loaded insects a few times a week, and come alive at dusk rather than during the day.

Temperament

Leopard geckos are small, ground-dwelling lizards that LafeberVet says make excellent pets, and the reasons are practical. They have movable eyelids and no sticky toe pads, so they cannot climb glass and are easy to keep contained; they are slow-moving and, once used to a person, generally tolerate gentle handling on a flat palm. The RSPCA advises scooping one up with both hands so all four feet are supported. They are crepuscular, which the RSPCA emphasizes: active at dawn and dusk, not in the middle of your afternoon, so a new owner should expect a lizard that is asleep in a hide for most of the day. The tail is the one handling rule. LafeberVet explains that leopard geckos use tail autotomy, and that the tail can fall off when grasped, sometimes with very little pressure; it regrows, but never restrain a gecko by it. They are solitary: the RSPCA says they do not need social company, and LafeberVet says males will fight each other. Most are captive-bred in many color forms.

“Leopard geckos are nocturnal, terrestrial, long-lived lizards that make excellent pets.”

Daily needs and attention

A leopard gecko's routine fits an evening. Each day: check the thermometers, since Merck wants at least two per enclosure with the heater on a thermostat; change the water, which VCA says should be in a shallow container and changed daily; and remove any waste. Feeding is the main task and it involves live insects. VCA says juveniles eat every 1-2 days and adults 2-3 times per week; the RSPCA says juveniles daily and adults every other day; LafeberVet suggests offering prey in late afternoon because the lizard is becoming active. Before each meal the insects need gut-loading, at least 24 hours per VCA, and a light dusting with a phosphorus-free calcium powder, with a small dish of plain calcium left in the tank. Keep the moist hide damp, remove uneaten crickets, and spot-clean. Handling can be brief and seated, a few times a week. Add a monthly deep clean and a yearly vet visit, and budget for a lizard that may live decades: VCA says 10-15 years, LafeberVet 25-30.

“Insects should be lightly dusted with a phosphorus-free calcium powder before they are fed.”

Health and lifespan

Leopard geckos are hardy and long-lived; VCA gives 10-15 years with good care, the RSPCA up to 20, Merck 20-plus and LafeberVet 25-30. Four conditions account for most vet visits, and LafeberVet lists them: nutritional secondary hyperparathyroidism (metabolic bone disease) from undusted insects and no calcium, cryptosporidiosis, cystic calculi (bladder stones) and dysecdysis. Retained shed most often sticks to the toes, where it cuts off circulation and can cost digits when the moist hide is missing. Cryptosporidiosis is a wasting protozoal infection that produces the classic stick-tail gecko and spreads easily, so quarantine a new gecko from any others. Tail loss from rough handling is not a disease but is a common visit. VCA's lighting page notes that even nocturnal species like leopard geckos raise their vitamin D after UV exposure, which is why UVB is recommended. Book a health check within two weeks with an ARAV-member veterinarian, bring a fresh fecal sample for parasite screening, and plan on checkups at least twice yearly, because reptiles hide illness until it is advanced.

“The tail can fall off when grasped, sometimes when very little pressure is applied.”

Habits and behavior

Watch a leopard gecko at dusk and its habits make sense. It leaves the warm hide, stretches, licks its eyes, and patrols the tank with a slow, deliberate walk, tongue-flicking as it goes; Merck explains that lizards, like snakes, use the tongue to carry air particles to an organ in the mouth that detects smells, and unlike snakes they have external ears and hear reasonably well. Hunting is the show: the gecko stalks a cricket, wags the tip of its tail, and strikes. The fat tail is its pantry, and a thick tail means a well-fed lizard; a thinning one is the earliest sign of trouble. It sheds in patches every few weeks and usually eats the shed skin, retreating to the moist hide to loosen it. Most choose one corner as a toilet, which makes spot-cleaning easy. Males are territorial, and VCA warns against putting two or more in one cage; the RSPCA recommends keeping leopard geckos by themselves. By day it is asleep, and that is normal.

“Male geckos can be territorial, so you must be careful when two or more male geckos are in one cage.”

Housing: enclosure, heat and light

VCA's minimum is a 10-gallon aquarium at least 6 inches high with a screen top, essential to prevent escape; LafeberVet says a single male needs a long 10-15 gallon tank; the RSPCA's minimum for one adult is 60 x 40 x 30 cm. Heat comes from below or a low lamp: VCA suggests heat tapes, under-tank heaters or low-level basking lights, rules out in-tank hot rocks, and says the gecko must not get closer than 6 inches to a heat light. Targets: VCA gives daytime temperatures in the mid-80s F (about 30 C) and nights as low as 70 F; LafeberVet gives an ambient 70-80 F with a 90 F warm area and nights in the 70s. Put the heater on a thermostat with a thermometer at each end. Humidity around 40-60 percent per LafeberVet, with a moist hide of damp sphagnum moss and a dry hide on the warm side. UVB is recommended but not required per VCA, placed 10-12 inches away and replaced every 9-12 months. Substrate: paper or reptile carpet; never coarse sand, corncob or walnut shell.

“Never use coarse sand, corncob bedding, or crushed walnut shells, as these bedding materials can be swallowed and will block the intestines”

Challenges

Plan for the insects. A leopard gecko will not eat vegetables, so you will buy or breed crickets, dubia roaches or mealworms for years, gut-load them, dust them with calcium, and chase the escapees; VCA notes uneaten crickets should not be left with the gecko. Plan for the schedule mismatch: this is a crepuscular animal, and a family expecting a daytime pet will mostly see a closed hide. Plan for the calcium, because the most common serious illness, metabolic bone disease, follows directly from skipping the dusting and the dish. Plan for the tail, which means teaching every person in the house never to grab it. Plan for the years: VCA's 10-15 is the short end, and LafeberVet's 25-30 means the gecko bought for a child will still be here when the child has moved out. And plan for the vet: VCA says some mistakenly believe reptile veterinary care is cheaper than for dogs and cats. None of this is hard, but all of it needs to be in place first.

The fun part

Leopard geckos are small enough to sit in one hand, patterned like their namesake, and they blink, which is a surprisingly endearing thing for a lizard to do. They are the lizard people reach for when they want something to hold: slow, warm, dry, and calm on a flat palm once they know you. Evenings are the entertainment, when the gecko emerges, hunts crickets with a tail-wagging stalk, and licks its own eyeballs clean. They come in dozens of captive-bred color forms, from high yellow to tangerine to patternless. The setup is modest and quiet: a 10-20 gallon tank, an under-tank heater and a couple of hides, and the whole thing fits on a desk. They are silent, nearly odorless, need no walks and no daily feeding as adults, and shrug off a weekend away. And with LafeberVet's figure of 25-30 years, a gecko adopted now can be a fixture through a whole stretch of your life. RSPCA's advice is simple: scoop gently, both hands, all four feet supported.

Living with kids and other pets

Leopard geckos are often marketed as a child's first reptile, and they are calmer and smaller than most. The limits are Salmonella and the tail. ARAV cites the CDC recommendation that children under five avoid contact with reptiles and that households with infants under one not own them; Merck lists children under 10, pregnant women, elderly people and anyone with a weakened immune system as more susceptible and says to supervise children around the reptile. An older child can hold a gecko seated over a soft surface, both hands, never by the tail, then wash with hot, soapy water. The gecko stays out of the kitchen and its dishes never go in a food sink; nobody kisses it. Other pets: a cat treats a moving gecko as prey, a dog can crush one, and a dropped gecko loses its tail, so the tank needs its screen top on and a room other pets do not roam. Geckos themselves live alone; the RSPCA says they do not need social company, and LafeberVet says males fight.

“Do not use the kitchen sink, kitchen counters, bathroom sinks or bathtubs to bathe reptiles or to wash reptile cages, dishes or aquariums.”

What to ask the rescue

How old is it, and how thick is the tail? A plump tail is a fed gecko; a thin one needs a vet before it needs a home. Has it lost its tail before? Is it eating, what insects, how often, and were they dusted with calcium? Any missing toes from stuck shed, which points to a past without a moist hide? Any tremors, soft jaw or limb swelling, the signs of metabolic bone disease? Has a reptile veterinarian examined it and run a fecal test, and was it ever housed with a gecko that wasted away, given the cryptosporidiosis risk? What heat, thermostat and UVB did it have? Was it housed with other geckos, and if male, alone? How does it handle? Then check your side: a 10-20 gallon tank with a screen top, an under-tank heater on a thermostat, two hides including a moist one, a calcium dish, a live-insect source, and a reptile vet within reach. VCA wants a new reptile examined within 72 hours of adoption.
