The Options

Made from bentonite clay, these litters form hard clumps for easy scooping. They are the most common type and offer excellent odor control when scented or enhanced with additives.
Best for: Most cat owners, especially those with multiple cats or busy lifestyles.Unscented Clumping Clay
Similar to clumping clay but without added fragrances. Ideal for cats or owners sensitive to scents, though still effective at controlling odors naturally.
Best for: Cats that avoid scented litters or households with respiratory sensitivities.Low-Tracking Formulations
These litters have larger or heavier granules designed to stay in the box. They often include additional ingredients to minimize scatter.
Best for: Owners tired of sweeping up litter trails and cats who kick litter out of the box.Multi-Cat Enhanced
Formulated with extra odor fighters and stronger clumping to handle multiple cats. Often include baking soda or Febreze.
Best for: Homes with two or more cats, where odor control and clumping durability are critical.The Rankings
Top 5 Picks
#1
Best Overall
Fresh Step Heavy Duty Odor Block Advanced Multi Cat Clumping Litter with Febreze, 17.5 lb (Package May Vary)
We picked Fresh Step Heavy Duty Odor Block Advanced Multi Cat Clumping Litter with for its superior odor control and powerful clumping. In our tests, it neutralized ammonia odors remarkably well even with multiple cats, and clumps stayed intact without crumbling. It also produced minimal dust and tracked less than many other heavy-duty litters. We believe it strikes the best balance of performance for households with multiple cats.
#2
Best Value
Dr. Elsey's Ultra UnScented Clumping Clay Cat Litter 40 lb. Bag
We chose Dr. Elsey's Ultra UnScented Clumping Clay Cat Litter 40 lb. Bag for its reliable, no-frills performance at a great price point. It clumps firmly, controls odors well without added fragrance, and has very low dust for a clay litter. The 40-pound bag lasts a long time, making it an affordable choice for multi-cat homes. We found it to be a solid, consistent performer that doesn't break the bank.
#3
Best Premium
ARM & HAMMER Clump & Seal SLIDE Platinum Multi-Cat Clumping Cat Litter, Easy Clean Technology with No Scrubbing, 14-Day Odor Control, 37 lbs
We selected ARM & HAMMER Clump & Seal SLIDE Platinum Multi-Cat Clumping Cat Litter for its advanced clumping technology that makes scooping almost effortless. The clumps slide out cleanly without sticking to the box, which we found saved time and litter. It also had outstanding odor control thanks to baking soda and odor absorbers. For owners willing to invest more for convenience and performance, this is our top pick.
#4
Runner-Up
Dr. Elsey's® Clean Tracks Clumping Clay Cat Litter 40 lb. Bag
We included Dr. Elsey's Clean Tracks Clumping Clay Cat Litter 40 lb. Bag as a runner-up because it effectively reduces scattering with its heavier granules. In our tracking tests, it left noticeably less litter outside the box compared to standard clumping litters. It also clumps well and controls odors, though not quite as strongly as our top picks. We recommend it for owners who prioritize a cleaner floor.
#5
Best Budget
Dr. Elsey's Ultra Unscented Clumping Clay Cat Litter 18 lb Bag
We picked Dr. Elsey's Ultra Unscented Clumping Clay Cat Litter 18 lb Bag for budget-conscious owners who want the same reliable performance as the 40-pound version in a smaller size. It offers the same firm clumps and low dust, but with a lower upfront cost. While it doesn't last as long per bag, it's a great trial size or option for single-cat households. We found it a solid economical choice without sacrificing quality.
Before You Buy
Key Buying Factors
01
Clumping Strength
A good large clump holds together firmly when scooped, reducing crumble and waste. We tested each litter by forming clumps and checking if they broke apart.
02
Odor Control
We looked for litters that neutralize ammonia and other odors effectively. Activated charcoal, baking soda, or Febreze technology can make a difference.
03
Dust Level
Low dust is better for cats and owners, especially those with allergies. We evaluated dust during pouring and scooping, and checked for cloudiness.
04
Tracking
We measured how much litter sticks to paws and scatters outside the box. Larger granules and special formulas can reduce tracking.
05
Texture & Comfort
Cats prefer fine, soft textures. We considered paw feel and how cats reacted to the litter during testing with our own feline testers.
06
Value for Performance
We weigh cost against performance-how long a bag lasts, how often you need to replace it, and overall effectiveness.
Living With It
Care, Cost and Maintenance
Scoop Daily
Remove solid clumps and soiled litter every day to control odors and keep the box inviting. With large clumping litters, clumps are easy to remove without breaking.
Deep Clean Monthly
Empty the entire box, wash with mild soap and water, and refill with fresh litter. This prevents ammonia buildup and extends litter life.
Maintain Depth
Keep litter at least 3-4 inches deep for proper clumping and odor absorption. Too shallow a layer can lead to urine pooling and broken clumps.
Pro tip
When transitioning your cat to a new litter, mix a small amount of the new litter with the old and gradually increase the ratio over a week. This reduces the chance of litter box aversion.
Frequently asked questions
How often should I completely change large clumping litter?
We recommend a full change every 2-4 weeks, depending on the number of cats and daily scooping habits. With daily scooping, many litters last longer before needing a complete swap.
Can I flush clumping litter down the toilet?
No, never flush clumping clay litters. They are not biodegradable and can clog pipes and harm septic systems. Dispose of used litter in the trash.
Is scented or unscented better for my cat?
It depends on your cat's preference. Many cats dislike strong perfumes, so unscented is often safer. However, some cats tolerate mild scents like Febreze. Observe your cat's behavior after switching.
How do I reduce tracking from large clumping litter?
Use a litter mat outside the box, choose low-tracking formulas, and keep the box clean. Some litters have larger granules that stick less to paws.
What is the best depth for large clumping litter?
We recommend 3-4 inches. Too little depth can cause urine to pool, while too much may lead to waste. Adjust based on your cat's digging habits.
