Quick Picks

If you want the fastest answer, start here:

Best Overall: A low-dust, strong clumping litter that controls ammonia odor well
Best Budget: A reliable clumping clay option with consistent odor control
Best for Sensitive Cats: A softer, low-fragrance formula (no added perfume)
Best Low-Tracking: Larger-grain or low-tracking formula to keep litter off floors
Best for Multi-Cat Odor: High-absorption formula + frequent scoop-friendly clumps

Buniva Tip: With multiple cats, odor control is 50% litter and 50% routine. Even the best litter won’t win if the box is too small or gets scooped once a day.

Buniva Score: How we judge odor-control litter

We rank cat litters using a consistent rubric:

Odor control (ammonia) over 24–48 hours
Clumping strength (tight clumps = less smell)
Dust level (less dust = cleaner home + happier lungs)
Tracking (how much ends up on floors)
Ease of cleaning (does it stick to the box?)
Scent approach (we prefer low/no perfume)
Value (cost per pound and how long it lasts)

What actually works for multi-cat odor control

1) Strong clumping + daily scoop beats “heavy fragrance”

Avoid heavily perfumed litters. They can smell “clean” for an hour but don’t solve ammonia long-term.

2) Bigger boxes and the right count matter

Rule of thumb: # of cats + 1 litter boxes.
If you have 2 cats, aim for 3 boxes.

3) Add a simple odor-control system

Scoop 1–2x/day
Full refresh (dump and wash) every 2–4 weeks depending on litter
Consider an air purifier near the litter area if odor is a major issue

FAQ

What’s the best routine for odor control?

Scoop daily, top off as needed, and fully replace + wash the box every 2–4 weeks depending on litter type.

Should I use deodorizing sprays?

Usually no. Sprays mask odor, but clumps and ammonia control fix it.

Is scented litter better?

Often worse. Heavy perfume can irritate cats and doesn’t solve ammonia long-term.
