Key takeaway
Scoop daily, wash weekly, replace litter regularly — more cats means more often.
How often to clean a litter box comes down to one fact: it’s a continuous source. The cat uses it every day, so the odor builds every day — which means the cleaning has to keep up.
What causes it
The litter box accumulates odor continuously. Daily scooping removes the fresh residue. Weekly washing removes the odor that builds up on the box walls. Regular litter replacement refreshes the whole thing.
Why it persists
The smell builds between cleans — the longer the gap, the more the odor accumulates. More cats or a smaller box means faster buildup and more frequent cleaning.
What actually helps
- Scoop daily — every day the box is used
