🦎 Introduction
Choosing the right substrate (floor bedding) is one of the most important decisions in setting up a safe enclosure for your leopard gecko. The wrong substrate can cause health problems like impaction, while the right one promotes natural behavior and easy cleaning.
In this guide, we’ll explore the best and worst substrates for leopard geckos—plus tips for picking the one that fits your setup and experience level.
✅ Best Substrates (Safe & Recommended)
1. Paper Towels
- Cheap, easy to replace, hygienic
- Great for hatchlings, quarantine tanks, or beginners
👉 Pros: Easy to clean, prevents impaction
👉 Cons: Doesn’t look natural
2. Reptile Carpet
- Soft, reusable mat cut to size
- Provides grip and decent aesthetics
👉 Pros: Washable, safe
👉 Cons: Can trap debris, needs frequent washing
3. Slate or Ceramic Tile
- Natural-looking, retains heat well
- Mimics gecko’s desert habitat
👉 Pros: Durable, safe, low maintenance
👉 Cons: Heavy, may need trimming to fit
4. Excavator Clay (For Advanced Keepers)
- Allows for custom tunnels and hides
- Naturalistic and enriching
👉 Pros: Enrichment, strong visual appeal
👉 Cons: Requires time and skill to set up properly
⚠️ Substrates to Use With Caution
5. Bioactive Soil Substrates (Expert Only)
- Complex natural systems using live plants and microfauna
- Requires exact humidity/ventilation balance
👉 Pros: Natural, long-term ecosystem
👉 Cons: Can harbor bacteria if not maintained well
❌ Substrates to Avoid
1. Loose Sand (including calcium sand)
- Risk: Impaction—geckos may ingest sand accidentally
- Calcium sand falsely marketed as “digestible” is dangerous
2. Wood Chips or Bark
- Sharp edges can cause injury
- Mold risk if moist
- Not suited to desert species like leopard geckos
3. Gravel, Pebbles, or Cat Litter
- Can’t be digested
- Dangerous if swallowed
- Not compatible with leopard gecko habitat needs
