Clumping cat litter has become one of the most popular categories in the modern pet-care market. Compared with traditional non-clumping litter, clumping products can absorb liquid and form compact masses that are easier for cat owners to remove. This makes daily litter-box cleaning more convenient and helps consumers use litter more efficiently.
Although small quantities of clumping litter can be produced with relatively simple equipment, manufacturing it at commercial scale requires much more careful control. Raw material quality, moisture, particle size, granulation, density, clumping strength, dust content, drying, screening, and packaging all influence the final product.
A properly designed cat litter production system integrates these stages into a continuous and efficient manufacturing process. Depending on the product type, the system may be based on bentonite, tofu, wood fiber, corn, cassava, or other absorbent materials.
This article explains how to manufacture clumping cat litter at scale, including raw material selection, formulation, processing technology, equipment selection, quality control, and factory design.
1. What Is Clumping Cat Litter?
Clumping cat litter is designed to absorb urine and form a relatively solid mass after contact with liquid.
The main advantages include:
- Easy removal
- Efficient litter-box cleaning
- Good liquid absorption
- Better odor management
- Reduced need to replace all litter
- Convenient daily maintenance
Bentonite is one of the most common raw materials for clumping cat litter because certain bentonite materials have strong swelling and binding properties.
However, plant-based clumping litter has also become increasingly popular. Tofu, corn, cassava, and other plant fibers can be formulated to produce clumping products.
2. Choose the Right Raw Material
The raw material determines the basic characteristics of the final product.
Common materials for clumping cat litter include:
- Sodium bentonite
- Calcium bentonite
- Soybean residue
- Soybean fiber
- Corn fiber
- Cassava starch
- Wood fiber
- Other plant-based materials
The ideal raw material should have suitable:
- Absorption
- Particle characteristics
- Moisture
- Binding properties
- Availability
- Cost
- Processing performance
Before designing the production line, manufacturers should test representative samples of the raw material.
3. Bentonite for Clumping Cat Litter
Bentonite is widely used in commercial clumping litter.
Its performance depends on mineral composition and processing conditions.
High-quality bentonite-based litter should provide:
- Rapid liquid absorption
- Strong clumping
- Appropriate particle size
- Low dust
- Good odor retention
- Stable storage
The raw mineral may need to be crushed, ground, screened, moisture-adjusted, granulated, dried, and screened before packaging.
The exact process should be adapted to the characteristics of the bentonite deposit.
4. Plant-Based Clumping Cat Litter
Plant-based clumping litter can be produced using materials such as:
- Soybean residue
- Corn fiber
- Cassava
- Pea fiber
- Wood fiber
These materials may require binders to improve clumping.
Starch is commonly considered because it can help particles bind together when exposed to moisture.
A plant-based formula may therefore combine:
Main Fiber + Starch/Binder + Odor-Control Ingredients + Optional Functional Additives
The formulation should balance clumping, absorption, pellet strength, and cost.
5. Test Raw Materials Before Production
Large-scale manufacturing should never begin without raw material testing.
Important tests include:
Moisture Content
Determines drying requirements.
Particle Size
Influences granulation and product texture.
Absorption
Shows the material’s ability to retain liquid.
Swelling or Binding Characteristics
Especially important for bentonite.
Density
Influences packaging and transportation costs.
Clumping Performance
Determines whether the final product can form stable clumps.
Testing helps manufacturers select suitable materials and avoid production problems.
6. Develop the Product Formula
A commercial clumping litter product should have a clearly defined formula.
For bentonite products, the formula may focus primarily on mineral quality and particle distribution.
For plant-based litter, a formula may include:
- Soybean fiber
- Corn fiber
- Starch
- Plant-based binder
- Activated carbon
- Odor-control additives
- Fragrance, if required
The formula should be tested for:
- Clump strength
- Absorption
- Dust
- Pellet durability
- Odor control
- Storage stability
A good formula balances performance with manufacturing cost.

The process for bentonite litter may be different.
The production flow should therefore be customized according to the selected raw material.
8. Step 1: Raw Material Receiving
Raw materials arrive at the factory by truck or other transportation.
A receiving system may include:
- Receiving hopper
- Conveyor
- Feeder
- Storage bin
- Dust collection system
For a large factory, automatic receiving reduces manual handling and improves production efficiency.
The receiving area should also provide protection against rain and contamination.
9. Step 2: Cleaning
Foreign materials should be removed before processing.
A cleaning system can remove:
- Stones
- Metal
- Plastic
- Soil
- Oversized material
Magnetic separators can remove ferrous metal.
Screens can separate oversized particles.
Cleaning protects crushers, grinders, pellet mills, and other equipment from damage.
10. Step 3: Crushing and Grinding
Large plant-based materials need to be reduced in size.
A crusher can process:
- Wood chips
- Bamboo
- Large fibers
- Agricultural residues
A hammer mill can then reduce the material to a more uniform size.
For plant-based clumping litter, appropriate particle size helps improve:
- Mixing
- Pellet formation
- Clump strength
- Product consistency
However, excessive grinding should be avoided because it increases energy consumption.
11. Step 4: Drying
Moisture control is critical to commercial clumping litter production.
Plant materials can enter the factory with high and variable moisture levels.
A dryer can reduce the moisture to a suitable range.
The drying system should provide:
- Uniform heat transfer
- Stable airflow
- Controlled residence time
- Appropriate final moisture
Rotary dryers are often suitable for continuous industrial processing.
Drying should not be excessive because over-drying wastes energy and may affect pelletizing.
12. Step 5: Batching
If several ingredients are used, accurate batching is required.
For example:
- 80% main plant fiber
- 15% starch or binder
- 5% functional ingredients
The actual formula should be determined through product testing rather than relying on a generic recipe.
Automatic batching equipment can improve:
- Formula accuracy
- Production consistency
- Labor efficiency
- Traceability
Large production facilities can integrate batching with PLC control.
13. Step 6: Mixing
After batching, the ingredients must be thoroughly mixed.
A commercial mixer distributes the materials evenly.
This is especially important when adding:
- Starch
- Binder
- Odor-control additives
- Activated carbon
- Fragrance
A homogeneous mixture ensures that the final product has more consistent clumping and odor-control performance.
14. Step 7: Moisture Adjustment
Before forming, moisture should be checked.
A controlled spraying system can add water if necessary.
Moisture affects:
- Pellet formation
- Density
- Strength
- Drying requirements
- Final absorption
If the material is too dry, pellets may not form properly.
If it is too wet, pellets can become soft and difficult to dry.
Therefore, moisture adjustment should be precise and uniform.
15. Step 8: Pelletizing or Granulation
This is the main forming stage.
Depending on the product, manufacturers can use:
- Pellet mill
- Granulator
- Other particle-forming equipment
A pellet mill compresses prepared material through a die.
The resulting pellets can be cut to the desired length.
A granulator may be preferred for products requiring different particle shapes.
The forming process influences the final litter’s:
- Density
- Particle size
- Strength
- Absorption
- Dust

16. Control Particle Size
Particle size is particularly important for clumping litter.
Very fine particles can create more dust.
Very large particles may affect:
- Absorption speed
- Clumping
- Cat acceptance
- Tracking
A screening system can separate particles into different size grades.
Manufacturers may develop several products with different particle sizes for different markets.
17. Control Pellet Density
Density influences how quickly liquid enters the litter particles.
If pellets are extremely dense, absorption can be slower.
If pellets are too loose, they may break easily.
Density depends on:
- Raw material
- Moisture
- Binder
- Compression
- Die specifications
- Pellet mill settings
The optimum density should be established through actual absorption and clumping tests.
18. Step 9: Drying the Formed Product
Freshly formed plant-based pellets may contain excess moisture.
A dryer can stabilize the product.
Important drying parameters include:
- Temperature
- Airflow
- Residence time
- Feed rate
- Initial moisture
- Target moisture
The objective is to remove sufficient moisture while maintaining pellet integrity.
Efficient drying is particularly important at large scale because energy consumption can significantly affect operating costs.
19. Step 10: Cooling
After drying, the litter should be cooled.
A cooler reduces the product temperature and prepares it for screening.
Cooling helps:
- Prevent condensation
- Improve storage stability
- Protect packaging
- Reduce product temperature
- Improve handling
The cooler should be properly matched to production capacity.
20. Step 11: Screening
Screening is essential for producing uniform clumping litter.
The screen separates:
- Fine powder
- Broken pellets
- Oversized particles
- Finished particles
A vibrating screen or rotary screen can be used.
Good screening improves:
- Appearance
- Particle consistency
- Dust performance
- Packaging accuracy
Suitable fines can potentially be recycled.
21. Step 12: Improve Clumping Strength
The main purpose of clumping litter is to form stable clumps after absorbing liquid.
Clumping performance depends on:
- Raw material
- Binder
- Particle size
- Moisture
- Density
- Forming pressure
Manufacturers should test clumps for:
- Formation speed
- Strength
- Breakage
- Liquid retention
- Ease of removal
A strong clump should remain intact during scooping.
22. Step 13: Odor Control
Liquid absorption alone does not guarantee good odor control.
Manufacturers may use suitable additives such as:
- Activated carbon
- Mineral adsorbents
- Plant-derived odor-control ingredients
These additives can be incorporated during mixing or applied through a coating system.
The final product should be tested under practical conditions to evaluate odor-management performance.
23. Step 14: Dust Control
Low dust is an important quality characteristic.
Dust can come from:
- Grinding
- Pelletizing
- Drying
- Cooling
- Screening
- Conveying
- Packaging
Dust reduction strategies include:
- Optimizing raw material grinding.
- Improving pellet durability.
- Screening out fines.
- Reducing unnecessary mechanical impact.
- Installing effective dust collectors.
A professional factory should include dust collection at major dust-generating points.
24. Step 15: Packaging
After quality inspection, the finished litter is packaged.
Typical packages include:
- 5 kg
- 6 kg
- 10 kg
- 15 kg
An automatic packaging machine can:
- Weigh the litter.
- Fill bags.
- Seal bags.
- Print batch information.
- Convey finished packages.
Moisture-resistant packaging is especially important for clumping products.
