Before You Buy
Key Buying Factors
01
Clumping Ability
Hard, tight clumps make scooping easy and prevent urine from pooling at the bottom. We evaluate clump integrity after 8 hours.
02
Odor Control
Effective odor control neutralizes ammonia and feces smells. We test over 72 hours in a covered litter box.
03
Dust Level
Low dust is better for cats with respiratory issues and keeps the surrounding area cleaner. We measure visible dust when pouring.
04
Scent Strength
Unscented options are best for sensitive noses, while some scented litters mask odors well. We note if the fragrance is overpowering.
05
Tracking
Litter that sticks to paws or scatters outside the box creates extra cleanup. We evaluate tracking on tile and carpet.
06
Cat Acceptance
Even the best litter fails if cats refuse to use it. We observe initial reaction and consistent use over a week.
Living With It
Care, Cost and Maintenance
Daily Scooping
Scoop clumps at least once daily to prevent odor buildup and keep the litter fresh. For multiple cats, scoop twice a day.
Weekly Deep Clean
Empty the box completely once a week, wash with mild soap and water, and refill with fresh litter. Avoid harsh chemicals that can deter cats.
Monitor Litter Depth
Maintain a depth of 2-3 inches to allow proper clumping and odor absorption. Add fresh litter as needed to maintain depth.
Pro tip
For the best odor control results, we recommend scooping twice daily and using a litter box with a carbon filter. This simple routine dramatically extends the life of any litter.
Frequently asked questions
How often should I replace the entire litter?
We recommend a full change every 3-4 weeks for clumping litters, or more often if you notice lingering odors. For natural litters, follow the manufacturer's guidance.
What's the best litter for multiple cats?
Our top pick for multi-cat households is Fresh Step Advanced Odor Shield Multi Cat, as its Febreze-infused clumps lock in odors well. Dr. Elsey's Ultra Unscented is also excellent for sensitive cats.
Is unscented or scented litter better for cats?
Cats generally prefer unscented litter because their sense of smell is much stronger than ours. However, some scented litters like Fresh Step are well-tolerated. We recommend starting with unscented.
Does clumping litter harm cats?
Most clumping litters are safe if used as directed. However, kittens and cats with respiratory issues may benefit from low-dust options like World's Best Cat Litter. Always monitor your cat's reaction.
What is the best way to reduce tracking?
Use a litter mat outside the box and choose larger particle litters like natural pellets. We found World's Best Cat Litter tracked less than fine clays.
