Key Takeaways at a Glance

Best environments for felt Dry enclosures, semi-dry enclosures, quarantine setups, breeding racks, temporary enclosures, and display enclosures

Environments that need caution High-humidity enclosures, semi-aquatic turtle setups, burrowing species, and animals that often tip over water bowls

Most versatile thickness For general enclosure flooring, 2mm is the most versatile. For small enclosures, 1.2mm works well, while 3mm can also be considered for medium-sized and larger enclosures.

Ordering Standard For the most accurate fit, order based on the actual inner floor width × length, not the outside dimensions of the enclosure.

1. Why Felt Works Well as Reptile Enclosure Flooring

Choosing reptile enclosure flooring is not just about selecting a material that looks good. It is important to consider whether the animal can move without slipping, whether there is a risk of swallowing flooring material while feeding, how easy it is to check droppings and clean the enclosure, and whether the flooring lays securely according to the enclosure size.

Easy to Cut to Custom Sizes

Felt is easy to cut into rectangles, rounded corners, or divided sections according to the inner floor dimensions of an enclosure. For enclosures with rounded corners, such as stackable cases, it can be cut with R10 or R15 corner radii.

Helps Reduce Slipping

Glass, acrylic, and PVC floors can be slippery because their surfaces are smooth. Felt provides moderate friction, helping the animal gain footing and improving traction on the floor.

Helps Reduce the Risk of Particle Ingestion

Unlike sand, bark, or wood chips, felt has fewer loose particles that can mix with food, making it easier to manage in quarantine setups, for young animals, or for animals with strong feeding responses.

Easy to Clean and Replace

Soiled areas can be checked quickly, and the felt can be removed and replaced as needed. Rather than using one sheet for a long time, it is better to prepare 2–3 sheets and rotate them.

Easy to Check Droppings

In quarantine or temporary enclosures, checking the condition of droppings is important. Felt makes it relatively easy to check the location and condition of droppings, which helps with health monitoring.

Neat for Display Enclosures

In shops, exhibitions, and reptile cafés, the inside of the enclosure should look neat and organized. Felt is easy to match by color and size, making it suitable for clean display setups.

2. Features and Recommended Uses by Felt Thickness

Felt Thickness	Recommended Uses	Features	YJ24 Recommended Series
Around 1.2mm	Small geckos, leopard geckos, temporary enclosures, and quarantine setups	Thin, lays flat on the floor, and dries quickly after washing. Good for small cases.	Solitone 1.2mm series
2mm	General lizard enclosures, small to medium geckos, leopard geckos, and small skinks	The most versatile thickness. It offers a good balance of cushioning, floor contact, and ease of maintenance.	Royal20 and Artifel M20 series
3mm	Medium-sized ground-dwelling lizards, enclosures that need extra cushioning, and display enclosures	Thicker and more stable. However, drying may take longer in humid environments.	MW30 series
4mm or thicker	Partial mats, selected areas in large enclosures, and impact cushioning	It may be too thick for full-floor coverage, so partial use is safer.	Artifel M40 series

Practical recommendation: For first-time use as reptile flooring, 2mm is the safest all-around choice. For small stackable cases, 1.2mm or 2mm is commonly chosen. For enclosures of 90×45cm or larger, 2mm or 3mm is often selected.

3. How to Use Felt by Enclosure Type

Stackable Plastic Case

Often used for geckos, baby animals, breeding racks, and temporary enclosures. It is convenient to cut several sheets in the same size and rotate them.

1.2mm 2mm R10/R15

Glass Terrarium

It is clean and easy to observe, but the floor can be slippery. Felt improves floor traction and gives the enclosure a neat look.

2mm 3mm Actual measurement recommended

PVC / Foamex Enclosure

Often used for medium to large enclosures because of its insulation and ease of maintenance. Felt works well with this type for floor protection and replaceable maintenance.

2mm 3mm Divided cutting

Screen Cage

It offers good ventilation, but misting and drainage management are important. Rather than covering the entire floor, it is safer to measure the inner tray and use felt as a partial mat.

Partial use Measurement required

Quarantine / Temporary Enclosure

Since droppings and condition need to be checked easily, a simple and easy-to-replace flooring material is best. Felt is highly useful as a quarantine mat.

1.2mm 2mm Rotating use

Display Enclosure

In stores or event spaces, a clean appearance is important. Felt matched by color and size works well for display enclosures.

6. Measurements to Check Before Ordering Felt Cutting

For felt flooring, it is most accurate to order based on the actual inner floor measurements rather than the enclosure name alone. Stackable cases, glass terrariums, Foamex enclosures, and screen cages can vary in internal size depending on the manufacturer and structure.

Enclosure brand and model name
Listed outside size
Actual inner floor width × length
Whether corners are rounded
Whether door rails or frames interfere
Location of water bowl, hides, and heat source
One-piece cutting or divided cutting
Reptile species and purpose of keeping

Cutting tip: If the felt is ordered too tightly, it may be difficult to insert and remove. For glass and Foamex enclosures, leaving about 2–5mm of clearance from the inner dimensions usually makes maintenance easier.

Examples of Divided Cutting for Large Enclosures

Enclosure Floor Size	One-Piece Cut	Divided Cutting Example
60×45cm	`595×445mm` 1 piece	`297×445mm` 2 pieces
90×45cm	`895×445mm` 1 piece	`447×445mm` 2 pieces
120×45cm	`1195×445mm` 1 piece	`595×445mm` 2 pieces
120×60cm	`1195×595mm` 1 piece	`595×595mm` 2 pieces
180×60cm	`1795×595mm` 1 piece	`895×595mm` 2 pieces or `595×595mm` 3 pieces

7. Precautions When Using Felt Flooring

Felt is easy to manage, but it is not a maintenance-free material. If wet felt is left in place for a long time, odor, mold, and bacterial growth can occur, so it should be replaced promptly when soiled or wet.

Be Careful in High-Humidity Environments

With automatic misting, high-humidity terrariums, or animals that frequently tip over water bowls, felt may remain wet for long periods. In these cases, using felt as a partial mat is safer than covering the entire floor.

Be Careful with Burrowing Species

For skinks, tortoises, and some lizards, digging behavior can be important. Rather than using felt alone, it is better to provide a soil/sand area or a dig box.

Check for Claw Snagging

If the felt becomes heavily pilled or frayed after long use, claws or teeth may get caught. If surface damage is visible, replacement is recommended.

Remove droppings as soon as they are found.
Replace wet felt immediately.
After washing, dry it completely before reuse.
Rather than using one sheet for a long time, rotate 2–3 sheets.
Do not share felt used for quarantine with other animals.

8. Frequently Asked Questions

Does the flooring size for a small stackable case vary by manufacturer?

Yes, it can vary. The JIF Stackable Small is usually 105×161×R10, Joy Clean Small is 163×108×R10, and Repaz Small is 160×105×R10, so the recommended sizes can differ. For accurate custom cutting, it is safest to confirm the enclosure brand or measure the inner floor directly.

What size should I order for flooring in a 30×30×45 glass enclosure?

In general, the floor is based on 30×30cm, but about 295×295mm can be recommended so it is easy to place inside. However, the size can vary depending on glass thickness and frame structure, so measuring the inner floor is recommended.

Which felt is good for a leopard gecko enclosure?

Leopard geckos are dry-setup reptiles that spend a lot of time on the floor, so felt flooring works well for them. For small or baby animals, around 1.2mm is suitable; for typical adult enclosures, 2mm felt is the most versatile.

Can crested geckos also use felt flooring?

They can, but crested geckos need vertical enclosures and careful humidity management. Keeping felt constantly wet is not recommended. It is better to place it only on the floor area and replace it immediately when soiled.

What felt thickness is the safest all-around choice for enclosures?

The safest all-around thickness is 2mm. 2mm felt is neither too thin nor too thick, offering a balanced fit to the floor, cushioning, and ease of washing. For small baby setups, 1.2mm can be used; for medium enclosures or extra cushioning, 3mm is also an option.

Felt Flooring Works Best as a “Managed Flooring Material”

Felt works well in reptile enclosures where cleaning, replacement, droppings checks, and custom cutting are important. It is especially useful in dry and semi-dry enclosures, quarantine setups, breeding racks, temporary enclosures, and display enclosures where efficient maintenance matters.

Before ordering, check the actual inner floor dimensions rather than the outside size of the enclosure. Stackable cases can vary by manufacturer, and the actual floor size of glass, Foamex, and PVC enclosures may be reduced by panel thickness and frame structure.
