It uses a triple-action blend of charcoal-infused tofu pellets, premium pea litter, and low-dust bentonite.

Many reviewers liked that Really Great Cat Litter, OdorStop is low-dust and low-tracking, and found it much less messy than other litters. One drawback is that it is a more expensive cat litter at $3.05 per pound. However, subscription options and multipacks can reduce these costs.

Made from whole-kernel corn, World’s Best Cat Litter Multiple Cat Unscented absorbs well. It forms strong clumps, making odor control easier. Reviewers found that it was low in dust and also appreciated that it is both biodegradable and flushable. 

While World’s Best Cat Litter Multiple Cat Unscented generally provides good odor control, some cat owners do note that it needs to be scooped more frequently than other litters. It can also break down faster in multi-cat homes and is more prone to tracking

Made from upcycled softwood, Catalyst Cat Litter Multi-Cat provides effective odor control and clumping. The softwood helps to absorb moisture while natural pine oils neutralize odors. Cat owners also appreciate that it is sustainable and gentle on their cats’ paws.

However, Catalyst Cat Litter Multi-Cat can be prone to tracking, and some cat owners found it dusty. It’s also on the more expensive side of cat litter options.

4. Arm & Hammer Clump & Seal Multi-Cat - Best for Odor Control

For odor control in multi-cat households, Arm & Hammer Clump & Seal Multi-Cat frequently comes up in conversations. The clay-based litter forms solid clumps that lock in odors and scoop easily, while added baking soda provides odor neutralization. Reviewers also found it less dusty compared to other clay cat litters.

Arm & Hammer Clump & Seal Multi-Cat has added fragrance in an attempt to mask odors. However, many cat owners found this unpleasant, and it can also be irritating to your cats. Some reviewers also found that it had a very sandy texture, which their cats didn’t like.

5. Dr. Elsey’s Ultra Litter - Best Value for Heavy-Duty Clay

Made with natural clay, Dr. Elsey’s Ultra Litter forms strong clumps to manage odors and make for easy scooping. Unlike many other clay litters, Dr. Elsey’s Ultra Litter combines heavy non-tracking granules with medium-grain clay to help prevent tracking. Sensitive humans and cats will also appreciate that it’s fragrance-free. 

Although Dr. Elsey’s Ultra Litter does use natural clay, it’s not an eco-friendly option, as clay isn’t biodegradable. Some reviewers also found that it can stick to the sides and bottom of the litter box, which can make for difficult cleanups.

6. Purina TidyCats Lightweight Free and Clean - Best for Budget

It’s made with natural clay to form clumps, while activated charcoal works to absorb odors. It’s also noticeably lighter and lower in dust than other clay litter options.

However, the lightweight, sandy texture means that it is more prone to tracking. It’s also not an eco-friendly cat litter option.

How to Choose the Best Cat Litter for Multiple Cats

When looking for cat litter for multiple cats, you’ll want to consider odor control, clumping, absorbency, dust and tracking, and value.

Multicat Odor Control 

When choosing multicat litter, odor control is a major factor. A fast-clumping litter is often best for odor control because it locks in odors quickly. It’s also a good idea to look for a cat litter with added natural odor control ingredients, such as activated charcoal, baking soda, zeolite, or probiotics. Dr. Maggie Placer, DVM, EveryCat Health Foundation Veterinary Sciences Program Manager,  and Feline Behaviorist Expert, advises against using heavily scented litter. It can deter some cats and irritate their respiratory systems.

Clumping 

Having multiple cats means more litter box cleaning, and having a litter that forms strong, solid clumps makes this easier. Bentonite clay litters are often known for forming firm clumps. However, natural alternatives such as tofu and corn also clump well. You’ll want to check for quick clumping, as this helps litter stand up to repeated use.

Absorbancy

Ultra absorbent cat litters absorb cat urine quickly, working to prevent ammonia odors from building up. This is especially important when you have multiple cats. Litters that offer the best absorption include clay, tofu, and wood. Choosing a high-quality absorbent litter can also mean that you’re changing your litter less often, getting more bang for your buck. 

Dust and Tracking

Dust and tracking are common cat litter pain points, and they can be even more pronounced when you’re dealing with larger amounts of cat litter. In terms of dust, clumping clay litter tends to be the dustiest, while natural options like tofu and corn are lower in dust. Dr. Placer notes that dust isn’t just messy. It can irritate your cat’s upper respiratory system. This is especially true for cats with asthma or chronic bronchitis. For tracking, granule and pellet-based litters tend to track the least, including tofu, pine pellets, and heavy corn. 

Value

When buying cat litter, it’s not always just about the price per pound. Higher quality litters can be more expensive per pound. However, they can be more effective, so you won’t need to change your cat’s litter as often. This means you’ll use less litter each month. This consideration is especially important for owners of multiple cats who are purchasing higher volumes of litter. You may also want to consider bulk buying, as this can further reduce your cost. 

How to Manage Litter Box Smell with Multiple Cats

If you’re dealing with persistent litter box smell with multiple cats, the right setup and cleaning routine can make a significant difference.

Multiple Cats = Multiple Litter Boxes

Not having enough litter boxes is a common mistake that cat parents make. Dr. Placer says that one per cat plus one extra is a general rule of thumb that works in many households. For example, if you have 2 cats, you’ll have 3 litter boxes. This ensures you have enough litter boxes so there are no territorial disputes and also spreads out litter use so that your litter can do its job. Dr. Placer recommends putting boxes around the house. In multicat homes, a dominant cat might guard one litter box.

Regular Litter Box Cleaning

Susan Nilson, Cat and Dog Training and Behaviour Specialist and Owner and Founder of The Cat and Dog House, says that cleanliness is the single most important factor for ensuring litter is effective in multicat households. This includes scooping the litter box at least once per day, ensuring that there are 2-3 inches of litter in the box. How often to change litter with multiple cats depends on the type of litter and the number of cats in your home. Most litters need a full change every 1-2 weeks, especially with multiple cats. 

Litter Box Size and Type

Nilson recommends litter boxes that are 1.5 times the length of your cat. This gives them enough room to turn around easily. She also notes that open litter boxes tend to work better in homes with multiple cats. We also suggest a high-walled litter box, as this helps keep litter contained within the box.
