Leopard Gecko Poop: What's Normal and What Isn't
| Normal stool | Firm brown log + white urate cap |
| Typical frequency | Every 1–2 days on a regular feeding schedule |
| See a vet if | Diarrhea, blood, straining, mucus |
What normal looks like
A healthy stool has two visible parts — a firm, dark brown fecal portion and a separate white or cream-colored urate (the reptile equivalent of urine, concentrated into a solid). Frequency varies with feeding schedule but is generally every day or two for regularly-fed geckos.
Normal variation
Minor day-to-day changes in size and frequency are expected and track with how much the gecko has recently eaten. Slight softness right after a fatty treat feeder isn't automatically concerning on its own.
Warning signs
Watery or consistently loose stool, visible blood, unusually foul or mucus-heavy stool, or repeated straining without producing anything can indicate parasites, infection, or impaction and should prompt a fecal test with a reptile vet.
Why checking matters
Stool checks are one of the easiest, lowest-effort ways to catch parasites like cryptosporidiosis early, since infected geckos can otherwise look outwardly normal for a long time.

A single adult leopard gecko needs a 20-gallon long tank as an absolute minimum, with a 36x18 in (40-gallon breeder) footprint now considered the recommended standard — plus a secure lid, an under-tank heater on a thermostat, a thermal gradient, at least three hides, and a shallow water dish.
Set up in this order: substrate, then heat source wired through a thermostat, then hides and water dish, then decor — and run the whole enclosure for at least 24–48 hours to confirm stable temperatures before your gecko moves in.
Hatchlings can start in a 10-gallon tank or tub, juveniles do well in 20 gallons, and adults need a 20-gallon long as an absolute minimum — with 36x18 in (40-gallon breeder) now the widely recommended standard, not just an upgrade.
Heat a leopard gecko enclosure with an under-tank heater and/or overhead heat source (halogen or deep heat projector) wired through a thermostat — a thermostat is mandatory, not optional, and heat rocks should never be used.
Leopard geckos can survive without UVB using dietary D3 supplementation, but current husbandry guidance now recommends low-level UVB (roughly 2–6% T5) as best practice — it improves D3 synthesis, bone density, and natural behavior, and views on it have shifted significantly from older nocturnal-species advice.
Keep ambient humidity around 30–40% across most of the enclosure, with a dedicated humid hide raised to roughly 70–80% to support smooth, complete sheds.
