It is better to change all the cat litter once a week. Cat litter will produce odor, impurities, and even breed bacteria if used for a long time. Therefore, in addition to cleaning the excrement in the cat litter every day, it must be replaced regularly. It depends on the material of the cat litter and the specific usage. As long as the cat litter is no longer dry and clean, it must be replaced in time.

The consequences of not changing cat litter:

1. Bacteria will breed. If the excrement in the cat litter is not cleaned for a long time, a large number of bacteria and parasites may breed, which is very unhygienic.

2. It will cause cats to get sick. Cats excreting in unhygienic litter boxes can easily become infected with bacteria and parasites, causing urinary tract diseases.

3. It will cause cats to urinate randomly. Cats are very clean animals. They are mysophobic and do not like to urinate in dirty litter boxes, so they will look for other suitable places to urinate.
