What should I watch for regarding species / breed and lifespan in leopard geckos?

A desert-native gecko, active at night and around dawn and dusk, one of the most widespread beginner gecko species, even-tempered and easy to care for. Lifespan as generally understood: 20+ years in captivity (Merck Vet Manual: "Leopard gecko: 20+ years" <https://www.merckvetmanual.com/multimedia/table/average-life-span-of-reptiles-in-captivity>, verified 2026-07-30). The actual judgement still rests with a veterinarian on a case-by-case basis, and this article gives no drug names or dosages.

What should I watch for regarding normal physiological indicators in leopard geckos?

What to measure: body weight, tail thickness and fullness (the fat storage indicator peculiar to geckos; a thinning tail is an important early warning sign of food refusal or illness), completeness of skin shedding (especially the toes and eyelids), activity level and appetite, and the character of faeces. Method: weigh on an electronic scale; compare the trend in tail thickness visually; check after a shed whether retained old skin forms a constricting ring on the toes (which can cause toe necrosis). Abnormal directions: the tail becoming obviously thin and pointed, retained shed on the toes or eyelids, and long-term food refusal. A quantified standard for tail thickness 【No single authoritative figure for this item: the whitelisted sources give no reference value for a quantified standard of tail thickness specific to leopard geckos; at present there are only qualitative descriptions (thinning = a warning sign), there is no accepted quantitative baseline, individual baseline body condition varies greatly, and the judgement should be made jointly by keeper and veterinarian on the individual's long-term trend, verified 2026-07-30】.

What should I watch for regarding the husbandry environment for leopard geckos?

A ground-dwelling species that needs bottom heating (an under-tank heater) to create a belly heat gradient, rather than relying on lamps alone. Traditional thinking held that UVB was unnecessary because the species is nocturnal, but the current trend is to provide low-intensity UVB to support vitamin D3 synthesis (the gecko has movable eyelids and can blink and close its eyes, but UVB lamps should still not be placed too close). A local humid microenvironment (a humid hide) is essential for a successful shed. Substrate must likewise avoid material that is easily ingested.
