Common cat litter

1. Bentonite cat litter. Bentonite cat litter is cost-effective and affordable, and it has good clumping properties and is not easy to stick to the bottom. It is more convenient to clean up excrement. The excrement wrapped in cat litter will hardly emit odor. However, some low-quality bentonite cat litter has relatively large dust, which can easily cause respiratory infections and urinary system diseases in cats, and can easily stick to the cat’s hair and be taken out.

2. Tofu cat litter. Tofu cat litter has a very good deodorizing effect, and it is healthier to use purely natural materials. The dust is relatively small and the water absorption effect is very strong. It can be poured directly into the toilet and flushed. However, tofu cat litter has poor clumping properties and is easy to stick to the bottom. It is troublesome to clean, and it is easy to get damp. If it is not cleaned for a long time, it will be prone to bugs. The smell of excrement and cat litter mixed together will be unacceptable.

3. Crystal cat litter. Crystal cat litter does not have any dust, has strong water absorption, can well wrap up the smell of excrement, has strong antibacterial ability, and can be used for a long time. However, crystal cat litter is relatively expensive and does not clump. Even if it can absorb urine after being used for a long time, the deodorizing effect will be lost. Moreover, it can have edges and corners that can easily get stuck into the cat's foot pads, and it can also be easily swallowed by cats.
