- 🍂 Before holiday guests
Your apartment is small, the litter box is a few steps from the couch, and guests are coming for the holidays. You clean the box, yet the smell still greets people at the door, and you are not sure whether candles or sprays are safe with a cat at home.
The fastest way to reduce litter box smell in a small apartment is a stricter routine: scoop at least daily, wash the box weekly with unscented soap, use enough boxes and skip heavy scents. Petstone's plan below shows what to do in the week before guests arrive, and when a smell change is a reason to call your vet.
Quick answer
- Scoop at least once a day, and twice on the days guests visit.
- Rinse the whole box with baking soda or unscented soap once a week, as the ASPCA recommends.
- Keep one box per cat, plus one extra.
- Choose unscented litter and skip candles, incense and strong sprays.
- A small odor device right next to the box can help on top of the routine.
Why litter boxes smell more in small apartments
Less space for air
In a studio or one-bedroom, the box often shares the room where you live and sleep. Any smell reaches you faster.
Waste left between scoops
Waste sitting in the litter is the main source. A longer gap between scoops means a stronger smell.
A worn box
Scratched plastic can hold odor even after scooping, which is why a weekly wash matters.
Too few boxes
The ASPCA's litter box guide suggests one box per cat plus one, so each box is used less.
How to clean the litter box so it smells less
The ASPCA recommends scooping at least once a day and rinsing the box out completely once a week. The Cornell Feline Health Center suggests scrubbing with a gentle detergent, drying the box and refilling it with clean litter.
- Remove clumps and waste daily, then top up with clean litter
- Keep litter about one to two inches deep, which the ASPCA says most cats like
- Use unscented litter; most cats prefer it, according to both sources
- Wash with unscented soap, not ammonia or vinegar cleaners
A one-week plan before holiday guests arrive
- Seven days out: empty the box, scrub it, dry it and refill with fresh unscented litter.
- Every day that week: scoop at least once, ideally morning and evening.
- Three days out: check the floor and wall around the box and wipe them with unscented soap.
- The day before: scoop, top up the litter and take the bag straight outside.
- While guests are there: scoop once more in the evening and keep the box area quiet for your cat.
Owners in small apartments often say the routine mattered more than any product, and that devices only helped once they scooped more often. Many also point out that if people can smell the box, the cat smells it even more.
What to avoid when fighting litter box smell
- Scented cleaners near the box, since the ASPCA says cats can develop an aversion to the scent
- Ammonia or vinegar cleaners, which Cornell says smell like urine and can be irritating
- Candles, incense and wax melts, which many owners warn against around pets
- Devices sold to make ozone; the California Air Resources Board recommends ozone generators not be used
What helps on top of a good routine
Once the box is clean, the next step is the air close to it. A small device placed right next to the box suits a bathroom or nook better than a large purifier across the room.
A compact, fragrance-free plug-in that releases negative ions to help with odors near the litter area. No filters to replace; best in small, enclosed spaces.
See the Litter Box Air PurifierThe Petstone Cat Litter Box Air Purifier is one option, and it works alongside daily scooping, not instead of it. To compare it with filter purifiers, sprays and litter changes, read do air purifiers help with litter box smell?
When a litter box smell means a vet visit
A sudden, stronger smell, a change in urine or stool, or a cat going outside the box can be a sign of a medical problem. Cornell says any medical condition that affects normal urination or defecation can cause litter box problems, and that cats having trouble using the box consistently should be checked by a veterinarian. See your vet if changes are persistent, severe or getting worse.

FAQ
How often should I scoop in a small apartment?
At least once a day, as the ASPCA recommends, and twice a day when guests are staying or the box is in a living space.
How many litter boxes do I need?
One per cat, plus one extra, according to both the ASPCA and Cornell.
Is scented litter better for smell?
Most cats prefer unscented litter, and a cat that dislikes the scent may avoid the box. Start with a clean box and unscented litter.
Can I use candles to hide the smell before guests arrive?
It is better not to. Many owners warn against burning candles or incense around pets, and covering the smell does not remove its source.
