The functions of cat litter:

1. When cats live in the wild, they like to excrete in soft land or sand, and then bury their excrement in the sand. When raising cats indoors, cat litter is used instead of sand.

2. Cat litter has a certain deodorizing effect and can wrap the odor of cat feces without spreading.

3. Cat litter has a certain adsorption effect, which can quickly absorb urine and keep the cat litter box dry, making it less likely to breed bacteria.

4. Cat litter has a certain coagulation effect. Bentonite cat litter can condense the cat's excrement into clumps. When cleaning the cat litter, you only need to remove the clumps of excrement.

5. Cat litter is more convenient to dispose of. There are some environmentally friendly cat litters, such as tofu litter, which can be flushed directly into the toilet and dissolve when exposed to water. They will not cause harm to the environment and are more convenient.
