The reasons why cats keep digging at cat litter:

1. Want to excrete. Before cats excrete, they will test whether the cat litter is soft and clean, and then dig a hole in the cat litter.

2. Want to cover up the smell. Masking the smell of excrement can prevent enemies from being discovered. This is a cat's nature, so after the cat has excreted, they will keep scratching the litter until the excrement is covered.

3. Want to play. Cats are very curious and naturally lively and active. If a cat feels bored and has nothing to play with, he will choose to play with cat litter.

Notes on using cat litter:

1. Not all cat litter can be poured into the toilet and flushed, and even cat litter that is soluble in water Don't pour too much sand at once. Pour it in several times. Flushing the toilet several times will avoid clogging the toilet.

2. The owner should keep the cat litter in a dry and ventilated place. Most of the cat litter will dissolve when exposed to water or clump when exposed to water, so once it gets damp, it is likely to affect the effectiveness of the cat litter. Or it may cause the cat litter to deteriorate.

3. Owners should pay attention to disinfecting the cat litter box. When replacing the cat litter, clean the cat litter box, then wipe the cat litter box with disinfectant water, or place the cat litter box in the sun. Exposed to the sun.
