A leopard gecko’s feeding amount depends on its age, growth, health, and body condition—not on one universal insect count. Growing geckos generally eat daily or every 1–2 days; adults are commonly fed every other day or about three times a week, though some care guides recommend less often. Offer appropriately sized live insects, remove uneaten prey, and monitor your gecko’s weight rather than treating a sample portion as a prescription.
How often should I feed a juvenile or adult leopard gecko?
Juveniles generally need more frequent meals than adults because they are growing. Reputable care guides differ on the exact schedule, particularly for adults, so use the schedules below as guidance—not as a rule that overrides your gecko’s age, health, or body condition.

| Life stage | Published guidance | How to interpret it |
|---|---|---|
| Juvenile | Daily, according to the RSPCA; every 1–2 days, according to VCA Animal Hospitals and PetMD. | Daily or every other day is within the range of these recommendations. Consider growth and condition when deciding where to start. |
| Adult | Every other day (RSPCA), three times weekly (VCA and PetMD), or about every three days for adults over one year in the Reptile & Rescue guide. | These are different care recommendations, not a single established consensus. Choose a consistent schedule and watch weight and condition. |
The RSPCA’s concise recommendation is: “Juveniles should be fed daily and adults every other day.” Other veterinary guidance is less frequent for some adults. The Reptile & Rescue guide gives a staged example of daily feeding up to six months, every other day from six to twelve months, and about every three days after one year. That age breakdown is that guide’s advice; it should not be mistaken for a universal standard.
There is no precise age at which every gecko should switch to an adult schedule. If you are unsure whether your gecko is still growing, or its weight or condition is changing, ask a veterinarian experienced with reptiles to help tailor the routine. Avoid increasing or reducing meals sharply based on age alone.

How many insects should I feed at each meal?
No universal insect count is established by the care sources reviewed. A useful starting point is an age-appropriate feeding schedule, followed by regular weight and body-condition checks; sample counts from individual guides are examples, not a prescription for every gecko.
| Guide | Example portion or method | Important qualification |
|---|---|---|
| Reptile & Rescue | Offer what the gecko will eat in 10–20 minutes; the guide says this is usually 4–10 insects per feeding. | The count is an example in that guide, not a cross-source standard. |
| Research Blvd Pet & Bird Hospital | Examples include 2–3 dusted insects morning and evening, 4–5 once daily, or 5–8 every other day. | The examples vary with schedule and age; they are not interchangeable universal meal sizes. |
These guides illustrate why a count alone can mislead: a portion paired with twice-daily feeding is not the same daily amount as a portion offered every other day. The insects themselves also vary in size. Do not combine the numbers from different schedules or assume that a gecko should finish a particular count.

What should a leopard gecko eat?
Leopard geckos eat live invertebrates. Offer a varied selection of suitable feeder insects rather than relying on a single treat or a fixed count. The RSPCA lists crickets, calciworms, and locusts. VCA also discusses commercially raised crickets and smaller amounts of silkworms, dubia roaches, mealworms, superworms, and waxworms. Research Blvd Pet & Bird Hospital names crickets, dubia roaches, and grasshoppers as main insect sources and cautions against making mealworms or superworms the main food.
Waxworms are high in fat, so the RSPCA advises feeding them sparingly. VCA also lists them among insects that can be offered in smaller amounts. Treat that as a reason not to rely on waxworms as a routine main feeder, rather than as a suggested meal portion.
How big should feeder insects be?
Choose prey conservatively: the guidance varies, but it consistently calls for insects sized to the gecko rather than oversized prey. The RSPCA says prey should be no larger than the gecko’s head. PetMD says it should be no longer than the head and no wider than half its width; a California Veterinary Emergency Team guide from UC Davis gives the more conservative guideline of approximately half the head size.

Because these descriptions are not identical, do not treat one precise measurement as a universal rule. When in doubt, choose smaller prey. A gecko’s age and size matter when selecting insects, and the portion examples above do not remove the need to size each feeder appropriately.
Should I remove uneaten insects?
Yes. Remove feeder insects the gecko has not eaten rather than leaving them in the enclosure, where they can bite or stress it. PetMD gives 10–15 minutes as a practical example for removing uneaten prey; it is a useful prompt, not a guarantee that every gecko or feeding situation follows the same timing.
If an insect remains uneaten, do not respond by leaving more prey in the enclosure or repeatedly offering oversized portions. Record what was offered and eaten, then consider whether the meal timing, feeder size, or schedule needs adjustment. If poor appetite persists or accompanies weight loss or other signs of illness, seek veterinary advice.

How should I prepare feeder insects and use supplements?
Gut-load feeder insects before offering them. The RSPCA recommends feeding them an appropriate formulated diet for 24–48 hours beforehand; VCA says to provide a high-quality diet for at least 24 hours. Follow the feeder-food directions and avoid assuming that an insect is adequately prepared just because it is alive.
Both sources also discuss dusting insects with supplements. Use the directions for the chosen product and seek veterinary guidance on an appropriate routine for your gecko. The RSPCA warns that vitamins and minerals can be overdosed, and notes that vitamin D3 needs depend in part on the UV setup. Those details make a one-size-fits-all supplement dose inappropriate; do not add extra supplements simply because a meal seems small.

Unexpected weight change deserves attention even if the gecko still eats. Persistent appetite loss, weight loss, weight gain, or other signs of illness are reasons to consult a veterinarian experienced with reptiles. Do not use a generic insect count as a substitute for an individual assessment.
How do I choose a practical feeding routine?
Start with the frequency range appropriate to your gecko’s life stage, then keep the routine consistent enough to monitor. Use these steps as a framework rather than a rigid feeding prescription:
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problems- Identify the life stage. Growing geckos are generally fed daily or every 1–2 days; adults are commonly fed every other day or three times weekly, with some guidance recommending about every three days for adults over one year.
- Select suitable live insects. Use a varied range of feeders from reputable sources. Keep high-fat waxworms and mealworms or superworms from becoming the main food, in keeping with the cited care guidance.
- Size prey conservatively. Choose insects no larger than the gecko can safely manage; when different guides use different size rules, favor smaller prey rather than assuming the largest stated size is necessary.
- Prepare feeders. Gut-load them for the period recommended by the care source or feeder-food instructions, and follow product and veterinary advice for supplements.
- Offer a reasonable meal and remove leftovers. Published counts are only examples. Do not leave uneaten insects in the enclosure.
- Monitor the gecko. Weigh regularly and note appetite, weight trends, and body condition. Ask a reptile-experienced veterinarian to assess concerns or help adjust the plan.
In short, feed for the gecko in front of you: use a more frequent schedule while it is growing, feed adults on a consistent but individualized routine, and let weight, condition, and veterinary advice guide adjustments. Neither a sample count nor one source’s schedule is a universal rule.
Frequently Asked Questions
Can I feed my leopard gecko only mealworms?
The cited care guidance describes mealworms as one possible feeder, not a recommended sole staple. Research Blvd Pet & Bird Hospital specifically cautions against making mealworms or superworms the main food, so include other suitable live insects in the diet.
Does my gecko’s UV setup affect which supplements it needs?
It can affect vitamin D3 needs. The RSPCA notes that D3 requirements depend in part on the UV setup, and warns that vitamins and minerals can be overdosed; follow product directions and ask a reptile veterinarian about your animal’s setup.
What if my gecko skips a meal?
One uneaten meal does not establish the right adjustment by itself, and the sources do not set a universal response to a skipped meal. Track appetite and weight; consult a reptile-experienced veterinarian if poor appetite persists, weight changes unexpectedly, or other signs of illness appear.
