How cat litter is actually made — from raw material to export-ready product — and what importers, distributors, and private-label buyers should verify before signing. A technical reference built for qualifying a factory, not just comparing spec sheets.
Cat litter manufacturing is a controlled process of raw-material preparation, forming (extrusion, pelletizing, or molding), drying, screening, and dust removal, followed by batch QC on moisture, dust level, clumping speed, and hardness. For B2B buyers, the decision points are: (1) material fit (tofu, bentonite, pine, mixed), (2) dust-control capability, (3) in-house formulation and QC testing, and (4) certification and export documentation. The articles linked below cover each step in detail.
Despite the variety of materials, most cat litters follow the same industrial backbone: raw-material receiving and screening, mixing or forming, drying and curing, particle-size classification, dust extraction, and final packaging. Understanding this flow lets a buyer ask the right factory questions — about batch consistency, changeover hygiene between formulations, and how dust is controlled at the source rather than only at the bag.
A step-by-step walkthrough of receiving, forming, drying, screening, and packing — the best starting point for evaluating a line.
Read the guideTofu (soybean residue) litter is formed by extruding a vegetable-fiber slurry into slender, fast-dissolving sticks. The variables that matter commercially are fiber source consistency, diameter tolerance, drying curve (which drives clump hardness), and the addition of deodorizing or binding agents. Clumping tofu and flushable tofu are the same base process with different post-treatment and additive profiles.
Raw material, extrusion, and drying explained for buyers evaluating a tofu production line.

View productBentonite is mined, crushed, conditioned with moisture, and pelletized or granulated so the clay expands and clumps on contact with liquid. The manufacturing levers are ore grade, granulation size, and the dust-suppression step. Bentonite also serves as the clumping backbone in many mixed formulas.

View productPine litter is produced from compressed sawdust or wood fiber (often a by-product stream), pelleted and sometimes heat-treated to lock in structure. Mixed formulations — most commonly tofu plus bentonite — require precise co-processing so the two materials clump together rather than separately. Formulation science is where a factory's R&D depth shows.

View productDust is the single most common B2B complaint and the clearest signal of weak process control. Effective dust management happens at three stages: forming (less brittle particles), screening (removing fines), and dedicated dust-extraction. QC then verifies the result with standardized testing.

Read the guideA factory's process control directly determines your landed quality, return rates, and brand reputation. Before contracting, verify: in-house production vs. trading, batch-to-batch consistency, dust and moisture QC, formulation flexibility for private label, certification (ISO 9001, BSCI, SGS, REACH as applicable), and export readiness (port proximity, documentation, container loading). Pet Horizon operates an integrated facility with in-house extrusion, drying, and QC labs, and supports OEM and private-label production across tofu, bentonite, pine, and mixed formats.
