Daily life and changing needs
Refresh water, remove waste and uneaten insects, check the animal and temperature readings.
Review weight trend and body condition; inspect toes, eyes and tail after a shed.
Check lighting, thermostat and room temperature changes; record any appetite decline.
Life stages
| Stage | What changes |
|---|---|
| Hatchling | Provide many small secure hides and a simple, observable feeding area. Offer suitably small insects daily once feeding has begun; log each meal and shed. |
| Juvenile | Continue frequent varied insects while growth is rapid. Weigh regularly, enlarge usable space and reassess prey size and supplement plan. |
| Adult | Feed less often according to tail and body condition, rather than pushing growth. Maintain the full gradient and monitor reproductive females for egg-laying needs. |
| Older animal | Track appetite, weight and mobility. A gradual change is still worth investigating, especially persistent weight loss or poor sheds. |
These are starting decisions for healthy captive animals. Adjust to measured conditions, body condition and veterinary advice. Hatchling, juvenile and adult ages vary by individual.
Build the choices
Think in usable ground area, not an empty volume. An adult starting point is roughly 90 × 45 × 45 cm, based on RVC’s 36 × 18 × 18 inch recommendation rounded to metric; more space is useful when it is furnished with low ledges, rock crevices, cork, leaf litter and cover. House singly by default. A warm hide, cool hide and humid hide should be genuinely distinct and accessible without crossing exposed ground. [RVC 2024] [IHS] [FBH 2023]
Use a guarded, thermostatically controlled daytime heat source. RVC gives around 32 °C at the basking area, around 25 °C at the cool end and a night floor around 20 °C. Those are starting references, not settings to dial in blindly: measure air at both ends with digital probes and surface temperatures separately with an infrared thermometer. Avoid hot rocks and unguarded lamps. [RVC 2024] [RVC lighting]
Give a regular day/night cycle. Low UVB may allow vitamin D synthesis, but the 2020 juvenile experiment did not show a six-month growth difference when D₃ was supplied in the diet. The older IHS lighting sheet urges care with bright, exposed setups. If using UVB, measure animal-level UVI at a reachable warm position and provide full shade; do not equate a tube’s percentage with delivered exposure. [IHS lighting] [UVB study 2020]
A damp, clean humid hide supports shedding without making the whole enclosure wet. A diggable, stable naturalistic substrate can enrich an established healthy animal; use an easy-to-observe quarantine setup for a newcomer or ill gecko. Remove soiled areas promptly. [RVC 2024] [IHS]
Food, water & supplements
Leopard geckos are insectivores. Rotate appropriately sized live crickets, locusts, roaches, silkworms or black soldier fly larvae rather than relying on one fatty feeder. Gut-load insects for the period recommended by the product and remove uneaten crickets; loose insects can bite a resting gecko. A specialist schedule suggests daily feeding for young juveniles, every two or three days as growth slows, and roughly every five days for many adults with a well-filled tail. Treat intervals as starting points, then follow body condition and veterinary advice. [ReptiFiles]
Dust feeder insects lightly with a calcium product and use an appropriate multivitamin programme. Dietary D₃ needs to be considered alongside measured UVB exposure and the ingredients of any complete supplement; avoid layering several D₃ products without checking totals. Reproductive females have higher calcium demands. Keep a shallow, clean bowl of drinking water available every day; misting alone is not a substitute. [ReptiFiles] [RVC 2024]
Hatchling to adult
A new hatchling should be warm, well covered and observed for its first shed, first meals, faeces and steady weight gain. Keep a feeding and growth log; small animals dehydrate more quickly and can be overwhelmed by large prey. Do not infer sex from appearance at an unreliable age. In a juvenile, adjust the habitat as it grows while preserving cover throughout the gradient. [ReptiFiles] [RVC 2024]
Adults need less energy than fast-growing juveniles. A broad tail is a reserve, but persistent swelling or a body that becomes uniformly rounded can signal overfeeding. Watch for retained skin at toes, a thinning tail, reduced grip, abnormal gait, eye closure or repeated refusal to eat. Support the body when handling, let the animal approach and never lift by the tail. Changes in behaviour are clues to investigate, not proof of a particular emotion or diagnosis. [ReptiFiles] [IHS]
Season, breeding & hatching
In winter some leopard geckos reduce activity and appetite; this is often called brumation rather than mammalian hibernation. Do not deliberately cool a young, underweight, recently acquired or unwell animal. First check heat, water, weight, faeces and health; consult a reptile vet before any planned breeding-season cooling. An unexplained refusal to feed should not be dismissed as seasonal. [ReptiFiles] [RVC 2024]
Females can lay infertile eggs without a male. A descriptive natural-history account reports clutches almost always of two and sometimes several clutches in a season. Provide an appropriate moist lay area and monitor weight and calcium intake. Straining, lethargy, a distended abdomen or failure to lay warrants urgent veterinary assessment. Incubation length varies with conditions; an older account reports around 45–53 days at 28 °C, which is context, not an instruction to select a sex or run an incubator by one number. Keep calibrated records and seek experienced support before breeding. Hatchlings need separate, secure, appropriately furnished housing and a plan for every animal produced. [ADW]
What to record & when to act
Record weight, feeding and prey type, sheds, faeces, water use, basking and cool temperatures, lamp details and behaviour. A sudden loss of tail mass, recurrent stuck shed, tremor, mouth discharge, breathing noise, swollen joints or persistent loss of appetite calls for a reptile vet. Review the enclosure and nutrition alongside the clinical assessment; a care sheet cannot diagnose the cause. [RVC 2024] [ReptiFiles]
