Why is my leopard gecko not eating?
A leopard gecko that goes off its food is nearly always reacting to its setup, most often a warm end that's drifted too cool to digest, an upcoming shed, or the seasonal winter dip. A single missed meal means little; a run of them, especially with a thinning tail, means more.
Check the warm-end temperature first
Leopard geckos digest through belly heat, so appetite hinges on the warm spot. They need a warm hide of around 30–32°C (86–90°F) measured at floor level with a digital probe (not a stick-on dial), if it's drifted a few degrees cool for several days, digestion and appetite quietly stall. Check the mat or bulb hasn't aged and the thermostat hasn't slipped before anything else.
Shedding, a new home, or the season
A gecko in shed often refuses food until it's finished, then eats normally again. A newly-bought or newly-moved gecko commonly won't eat for one to two weeks while it settles, keep the setup stable and handle it as little as possible. In autumn and winter, cooler rooms and shorter days trigger a natural slow-down, and many geckos eat less or skip meals for weeks while otherwise healthy.
Is the feeder the problem?
The wrong food can look like a hunger strike. Prey that's too large is intimidating and can be refused outright (a good rule is nothing wider than the space between the gecko's eyes), while a monotonous feeder or one the gecko has simply gone off can dull interest. Try a smaller, livelier feeder or a different staple insect before assuming something is wrong.
When it's more than fussiness
Refusal paired with a thinning tail, weight loss, lethargy, straining, or a swollen belly points past picky eating, impaction from swallowed substrate, for one, can block the gut and kill appetite. Weigh the gecko and track the trend: it's the direction of the weight, not any single skipped meal, that tells you whether there's a real problem.
When to see a vet
See an exotics vet if a gecko refuses food for more than a couple of weeks outside the cooler season, if the tail is thinning or weight is dropping, or if refusal comes with lethargy, straining, a bloated belly, sunken eyes, or abnormal stool.
One reading rarely tells the story. What matters is whether it's an isolated blip or part of a trend, so look at recent weight, feeding intervals, shedding, temperature and behaviour together.
baskr keeps those records in one place and watches the pattern for you, so you can see whether something has genuinely changed with your leopard gecko, before it becomes a problem.
Track my leopard gecko freeRelated questions
Why did my leopard gecko suddenly stop eating?+
A sudden change most often means the warm hide has dropped below about 30°C (a failing mat, bulb or thermostat), a shed is coming, or the winter slow-down is starting. Rule out belly heat first, then look at the season and shed cycle.
How long can a leopard gecko go without eating?+
A healthy adult can safely go a couple of weeks, and longer during a winter dip, because it lives off its tail reserves. Juveniles should eat far more often, so track the tail and weight trend rather than counting missed meals.
Why won't my leopard gecko eat its crickets or mealworms?+
It may find the feeder too large or intimidating, or simply have gone off that insect. Offer smaller, livelier prey nothing wider than the gap between its eyes, or switch staple, before assuming illness.
Why is my new leopard gecko not eating?+
New geckos commonly refuse food for one to two weeks while they settle in. Keep the setup stable, minimise handling, and give it time, but keep an eye on the tail and weight.
