Cat litter is usually changed once a week to a month. The specific replacement cycle depends on the type of cat litter and the actual situation. Bentonite cat litter is generally replaced once a week or so, while crystal cat litter can be extended to about a month. But no matter what kind of cat litter it is, if you find that the cat litter is particularly dirty or smelly, you must replace it 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.

4. It will affect the cat’s mood. Cats do not have a clean place to urinate, or they cannot find a more suitable place to urinate. They often hold back their urine, which can cause cats to become anxious and irritable.

5. It will affect the owner’s life. If the cat litter box is not cleaned for a long time, the smell will be very strong, and dry cat litter dust will float in the air, which will have a great impact on the owner's life.
