The global cat litter market has evolved far beyond traditional clay products. As consumers become more environmentally conscious and pet owners demand safer, healthier options, manufacturers have developed a wide range of cat litter made from renewable plant materials, minerals, and advanced absorbent technologies. Today, cat litter brands, distributors, and private label companies can choose from dozens of formulations to meet different market needs.
For businesses entering the cat litter industry, understanding how cat litter is made is essential. Although every manufacturer has proprietary formulas, the basic production principles are similar. Different raw materials require different manufacturing processes, equipment, and quality control methods.
This guide provides an overview of the major cat litter types, explains how each is manufactured, and helps cat litter brands, importers, wholesalers, and distributors better understand the production process before selecting an OEM manufacturing partner.

Pea fiber
Natural gums
Production includes:
Mixing
Moisture adjustment
Extrusion
Pellet cutting
Drying
Cooling

Packaging
The result is a lightweight cylindrical pellet with excellent water absorption.
These pea residue play a crucial role in the production of tofu cat litter. Next, the extracted pea residue is processed to transform it into cat litter suitable for cats. First, the pea residue is ground into small particles, and during this process, a certain amount of water is added to facilitate the grinding into fine granules. Subsequently, these moist particles are subjected to drying and dehydration methods to reduce their moisture content, achieving a certain level of dryness. At this stage, most of the pea residue has been converted into fine particles with some degree of moisture absorption and clumping ability. However, further processing is still needed to enhance its absorbency and clumping properties.To achieve this goal, we will incorporate a certain proportion of food-grade cornstarch and guar gum and mix them evenly. The addition of these ingredients enhances the moisture absorption properties of tofu cat litter, allowing it to quickly absorb urine and clump together for easy cleaning.
Additionally, to provide effective odor control and a better user experience, we can add fragrances according to customer preferences.The use of these additives undergoes rigorous inspection and testing to ensure they have no adverse effects on the safety and health of cats. Once the raw materials are thoroughly mixed, they are conveyed to a pelletizer for compression and shaping, extruded into the desired cylindrical shape, and then subjected to drying and sterilization. It's crucial to closely monitor the moisture content during the drying process, as it directly affects the user experience of the cat litter.
After drying and sterilization, the cat litter is cooled, dusted, and processed to reduce the final product's dust content. Following this cooling phase, the cat litter goes through three stages of vibration sieves to eliminate dust, ensuring that the cat litter enters packaging without any dust particles. Finally, through stringent quality control and packaging procedures, the tofu cat litter is placed into bags or boxes and packaged.
Overall, the production process of tofu cat litter adheres to a scientific approach to raw material handling and processing, from the extraction of protein from peas to the addition of absorbents and fragrances, and finally to rigorous quality control and packaging. Each step has undergone careful scientific research, development, and testing. By understanding these processes, we can gain a better understanding of the production and use of tofu cat litter, ultimately providing a more comfortable and healthy living environment for our pets.
Judging from the detailed manufacturing process of tofu cat litter, other cat litters have a similar process.
