At present, tofu cat litter on the market is mainly composed of pea fiber, corn starch, and soybean residue. Among them, pea fiber has good water absorption, corn starch can play a certain bonding role, and soybean residue is one of the main raw materials.

However, in order to reduce costs, some bad businesses may use leftovers from furniture factories, waste materials and wood flour from food processing factories to replace some or all of the above ingredients, and then cover up the odor and color of these materials by adding essence and colorants. This low-quality tofu cat litter may have safety hazards, such as excessive formaldehyde and chemicals, which can pose risks to the health of cats.

High quality tofu cat litter usually has the advantages of environmental protection, natural and non-toxic ingredients, strong water absorption, solubility in water (can be directly flushed into the toilet), good clumping properties, and good deodorization. But it also has some drawbacks, such as relatively high price, susceptibility to moisture in summer, potential insect infestation due to improper storage, and some tofu cat litter is prone to sticking to the litter box, with a certain amount of dust, as well as the possibility of chemical reactions between cat urine and it, leading to the emission of unpleasant odors.

When choosing the tofu cat litter, you can distinguish its advantages and disadvantages by observing the particle color (normally it is not snow-white, and may be slightly yellow), testing the water absorption (the agglomeration effect is good), and smelling the flavor (slightly plant flavor or food flavor, rather than pungent or strong essence flavor). Meanwhile, it is recommended to choose products from reputable brands.
