Best Cat Litter on Amazon 2025: Top-Rated Brands Compared for Odor Control & Value

If you’re shopping for cat litter, you probably want something that keeps your home smelling fresh, is easy to scoop, and won’t irritate your cat — all without breaking the bank. You might be comparing Boxie Probiotic Cat Litter, Dr. Elsey’s Ultra Unscented, ARM & HAMMER Ultra Last, and PrettyLitter, and wondering which one fits your routine and your cat’s needs. Each of these options takes a different approach — clumping clay with probiotics, classic unscented clumping clay, baking-soda–enhanced multi-cat clumping clay, and a lightweight, color-changing silica gel — so thinking about dust, tracking, odor control, and health monitoring will help you pick the right one.

Over the years cat litter has moved from simple absorbent substrates to specialized formulas designed for convenience and cat health. Traditional clay litters evolved into clumping clay that makes scooping easier; silica gel “crystal” litters arrived offering low tracking and strong odor control; and manufacturers started adding baking soda, probiotics, or other odor-neutralizing agents to tackle smells without heavy perfumes. More recently, health-monitoring litters that change color have given owners a new tool for spotting potential urinary issues early. The benefits you can expect from these modern options include superior odor control, simpler cleanup, less dust (better for respiratory health), formulas suited to multi-cat households, and even insights into your cat’s urinary health.

In the article ahead, you’ll get a closer look at each product’s strengths and trade-offs — Boxie’s probiotic approach, Dr. Elsey’s unscented clumping reliability, ARM & HAMMER’s baking-soda boost for multi-cat homes, and PrettyLitter’s lightweight, color-changing crystals. You’ll see how they compare on odor control, clumping performance, dust and tracking, handling and cost, and which kinds of cats and households are likely to benefit most from each choice.

Boxie Probiotic Clumping Cat Litter, 16 lb — 40-Day Odor Control, Dust-Free, Unscented, No Fillers

Boxie Probiotic Cat Litter (16 lb) is designed for cat owners who want a high-performing clumping clay kitty litter that focuses on real odor elimination, low dust, and long-lasting performance. You’ll reach for this litter if you want reliable ammonia odor elimination, minimal tracking, and a product that’s compatible with both manual and automatic litter boxes. It’s aimed at households that prefer no fragrances, no fillers, and a veterinarian-approved formula that’s gentle on sensitive cats and allergy-prone people.

• 40-day odor control: Boxie promises up to 40 days of odor control — roughly 2x longer than leading competitors — so you can go longer between full litter changes.
• Probiotic odor control: Instead of masking smells with fragrances, Boxie uses odour-eliminating probiotics that work around the clock to address the cause of odor, not just the scent.
• 99.9% dust-free: Expect minimal tracking and less litter dust settling on floors or furniture, which helps keep your home cleaner and your air clearer.
• Clumping and easy scooping: Clumps form at the top of the box for easy removal, so daily maintenance is quick and tidy.
• No fragrances or fillers: The formula is hypoallergenic, veterinarian-approved, and free from cheap additives and harsh chemicals — good if you’re cautious about what you bring into your home.

Boxie Probiotic Cat Litter is a clumping clay litter infused with beneficial probiotics. These microbes actively break down the bacteria that produce unpleasant smells — particularly ammonia — so your litter box smells fresher for longer. The probiotics operate continuously, offering 24-hour mitigation of odor after each use.

• Guaranteed 40-day odor control — outperforming many chemical-based litters that only mask smells.
• Probiotic-based odor elimination — targets cause rather than scent.
• Clumping action — clumps form on top for faster scooping.
• 99.9% dust-free — lowers tracking and dust buildup in your home.
• No fragrances, no fillers — safe for sensitive cats and people.
• Compatible with automatic litter boxes — smooth performance with sifting and mechanical boxes.
• 16 lb bag — a balance of weight and duration; designed to last ~30–40 days.

You’ll still scoop daily, but you’ll likely replace the entire box less often thanks to the long-lasting formula. Because clumps are easy to remove and dust is minimal, cleanup is less messy. If you use an automatic box, Boxie’s consistent clumping and low dust are advantageous for avoiding jams and extra maintenance.

The overall quality of Boxie Probiotic Cat Litter scores high in odor control and day-to-day usability. The probiotics provide a measurable functional difference compared with purely fragranced litters, reducing the need for constant deodorizing sprays or multiple litter changes. The clumping is reliable — clumps don’t stick to the bottom — which saves you elbow grease when you clean. Packaging and the 16 lb size make it manageable to lift and pour, and the product’s veterinarian approval adds confidence that it’s formulated responsibly without harmful preservatives.

You should expect to replace the litter approximately once a month under normal single-cat usage, and possibly sooner with multiple cats or heavy use. While Boxie advertises “self-cleaning,” you’ll still be removing clumps — the probiotics help prevent lingering odor between scoops but don’t eliminate all maintenance.

• Effective 40-day odor control with probiotic action
• Eliminates ammonia odor rather than masking it
• 99.9% dust-free — less tracking and cleaner air
• Clumps on top for easy scooping
• No fragrances, no fillers, veterinarian-approved — safer for sensitive cats and households
• Compatible with automatic and sifting boxes
• Cost per bag can be higher than basic clay litters, though longer use offsets some expense
• Performance may vary with multi-cat households — heavy traffic may require more frequent changes
• Some cats prefer different textures; if your cat dislikes clay, this won’t be the best choice

If you want a low-dust, fragrance-free, clumping litter that actively fights the root causes of odor and stretches the time between full changes, Boxie Probiotic Cat Litter delivers a smart, vet-approved solution built for convenience and cleaner-smelling homes.

Dr. Elsey’s Unscented Clumping Cat Litter — 18 lb bag

You’re looking for a reliable, unscented clumping cat litter that handles everyday use without fuss. Dr. Elsey’s Ultra Unscented Clumping Clay Cat Litter (18 lb bag) is designed primarily as a daily-scoop litter for both single- and multi-cat households. If you want an option that keeps the box tidy, traps odors naturally, and is gentle on sensitive noses, this product was built with those priorities in mind.

If you or your cat have sensitivities, allergies, or dislike fragranced litters, you’ll appreciate the hypoallergenic and unscented formula. It’s also a good match if you want hard clumping, easy scooping, and low tracking—so you spend less time cleaning around the box and more time enjoying your cat.

You’ll notice fast-forming, hard clumps thanks to the 100% bentonite clay base and medium-grain texture. Those clumps hold together when scooping, which keeps moisture from seeping to the bottom and makes litter maintenance straightforward.

Because this litter is 99.9% dust-free and unscented, it minimizes airborne irritants that can bother you or your cat. That’s especially important if you’re managing allergies, respiratory conditions, or have kittens who need a gentler environment.

An 18 lb bag gives you a solid amount of litter before you need to repurchase, and its strong clumping means you’re scooping less frequently than with weaker formulas. The low tracking medium grain helps keep your floors cleaner, which reduces how often you sweep or vacuum around the litter box.

This litter is made to be a dependable, low-maintenance foundation for your cat’s daily bathroom needs. It balances performance—superior odor control, hard clumping, and low dust—with comfort for sensitive cats and owners.

• 100% bentonite clay for strong clumping and absorption
• Hard clumping that prevents moisture from reaching the tray bottom and makes scooping neater
• 99.9% dust-free and hypoallergenic formula suitable for allergy-prone homes
• Unscented (no masking fragrances) for sensitive noses
• Superior odor control using natural ingredients to keep your home smelling fresh between cleanings
• Low tracking medium grain helps keep litter in the box and off your floors

These features mean you can spend less time managing the litter box and more time with your cat—exactly what you want from a reliable litter.

You’ll find the overall quality to be high: the granule size and texture are crafted for consistency so clumps form reliably and don’t crumble when you scoop. That consistency translates to cleaner boxes and fewer leftover residues.

The unscented, hypoallergenic formulation is thoughtful for households concerned about chemicals or perfumes. The nearly dust-free profile reduces the mess in the surrounding area and the chance of coughing or sneezing for both you and your cat.

Bentonite clay is effective but not biodegradable, so if you’re prioritizing compostable or eco-friendly litters, you might prefer a plant-based option. Still, for sheer day-to-day performance—odor control, clump strength, and scoopability—this product ranks highly.

• Hard clumping: forms sturdy clumps that are easy to scoop
• 99.9% dust-free: minimizes mess and respiratory irritation
• Unscented & hypoallergenic: great if you or your cat are sensitive to fragrances
• Superior odor control: natural approach keeps odors at bay between scoops
• Low tracking: medium grain helps keep litter inside the box
• Good value per bag: 18 lb size lasts and reduces frequent repurchases
• Heavy bag: an 18 lb bag can be bulky to lift and carry, especially up stairs
• Non-biodegradable: made from bentonite clay, so it isn’t compostable
• Some cats prefer softer or scented litters: if your cat likes a different texture or aroma, they may take time to adjust
• Can harden in humid climates: in very wet conditions, you might need to replace the litter more often to maintain clump integrity

If you want an unscented, robust-performing clumping litter that you can scoop with confidence and that minimizes dust and tracking, Dr. Elsey’s Ultra Unscented Clumping Clay is a strong option to consider for your home and your cat’s comfort.

Arm & Hammer Ultra Last Unscented Clumping Cat Litter — Multi-Cat, 18 lb, Baking Soda Odor Control (Pet-Friendly)

You’ll find ARM & HAMMER Ultra Last Clumping Cat Litter Unscented MultiCat 18 Lbs. ideal if you have multiple cats or a busy schedule that doesn’t always allow daily scooping. It’s designed for homes where long-lasting odor control is a top priority and where you want a low-fuss, unscented option that’s gentle on both noses and pets.

Use this litter in shared litter boxes, multi-cat households, or rooms where strong fragrances would be unpleasant. Because it’s coated with ARM & HAMMER Baking Soda and formulated to be virtually dust free (99%), it works well in apartments, homes with sensitive humans or cats, and in spaces where you want minimal tracking and cleaner floors.

You’ll appreciate the combination of Baking Soda freshness and clumping performance. The litter’s odor eliminators and baking soda granules tackle smells proactively, so your box stays fresher longer—especially helpful when you can’t scoop every day. Being unscented, it won’t mask odors with perfumes, which many cats and people prefer.

This is an online exclusive 18 Lbs. package, a convenient mid-size that makes it easier to stock up and store. The low tracking and virtually dust free claims mean less cleanup for you and fewer dust-related allergies or respiratory irritations for your family and cat. If you want dependable odor control without added fragrance or fuss, this litter covers that need well.

The product’s purpose is straightforward: provide powerful odor control and clumping performance in a pet-friendly, unscented formula. It uses ARM & HAMMER Baking Soda to neutralize ammonia and other litter box smells rather than just covering them up, which helps maintain a fresher environment between scoops.

• Long-lasting odor control — baking soda granules and odor eliminators work even when you can’t scoop daily.
• Unscented — no added fragrances, so your cat’s sense of smell isn’t overwhelmed.

You’ll notice the litter clumps well, allowing you to scoop with confidence and keep the box tidy. The odor control is strong thanks to the combination of baking soda and odor eliminators; it’s specifically designed to remain effective between cleanings. For multi-cat households, this formula tends to hold up better than basic litters that rely on scent masking.

If you’re concerned about dust or tracking, this litter scores high: it’s virtually dust free (99%), which helps reduce respiratory irritation for sensitive cats and people. The low tracking design keeps granules in the litter area longer, meaning less sweeping and vacuuming for you. The unscented profile also reduces the risk of sneezing or aversion by scent-sensitive cats.

• Effective odor control thanks to ARM & HAMMER Baking Soda and odor eliminators.
• Unscented, so it’s suitable for scent-sensitive cats and humans.
• Good clumping performance makes scooping easier and reduces litter waste.
• Virtually dust free (99%), improving air quality and reducing mess.
• Low tracking, so floors and litter areas stay cleaner.
• Convenient 18 Lbs. online-exclusive packaging allows you to buy multiples to last longer.
• If you prefer scented litters, the unscented formula may feel less immediately “fresh” even though it neutralizes odors.
• The 18 Lbs. size, while convenient for storage, may require more frequent reordering than larger bulk bags if you have many cats.
• Some cats might prefer different textures; if your cat is picky about granule size or feel, you may need to test compatibility.

If you want a dependable, unscented litter that prioritizes real odor neutralization over masking and keeps dust and tracking to a minimum, this option is a solid pick. It balances performance and pet-friendly features so you and your cats can enjoy a cleaner, fresher litter area with less effort.

PrettyLitter Cat Litter — Unscented, Non-Clumping Silica Gel Crystals, Color-Changing Health Monitor, Lightweight & Low-Tracking, Odor Control, 6 lb (1‑Month Supply)

You want a litter that simplifies daily care, helps control smell, and gives you extra insight into your cat’s urinary health without invasive testing. PrettyLitter Health Monitoring Cat Litter (Unscented, Non Clumping) is designed primarily as a low-maintenance, lightweight silica gel litter that both controls odor and warns you about potential urinary issues by changing color based on urinary pH and the presence of blood. Each 6 lb bag is marketed as a one month supply for a single cat, so it’s intended for pet owners who value convenience, health monitoring, and a cleaner, lower-dust box experience.

You’ll appreciate how PrettyLitter reduces the physical hassle of litter maintenance. Because it’s non-clumping silica gel, you don’t have to deal with heavy clay or constant refills — just scoop out solid waste and replace the litter monthly. The lightweight bags make storage and carrying easier, and the low tracking, low dust formula helps keep your floors and air cleaner. The added advantage is the color-changing crystals that act as an early-warning system for potential issues like UTIs, kidney concerns, or blood in urine, letting you act quickly and seek veterinary advice when needed.

PrettyLitter’s core purpose is twofold: superior odor control and at-home health monitoring. The litter uses absorbent silica gel crystals with millions of micropores that soak up moisture and trap urine internally (rather than forming clumps around it). This helps dehydrate feces and neutralize smells before you scoop.

Key features include:

• Color-changing silica gel crystals that shift hues to indicate changes in urinary pH and detect the possible presence of blood — a non-diagnostic but useful health signal.
• Unscented, non-clumping formula for households that prefer fragrance-free products or have scent-sensitive cats.
• Lightweight and low tracking, up to 80% lighter than traditional clay litters, making handling and storage easier for you.
• Advanced odor control through absorption, not just masking, so your home stays fresher between scoops.
• Vet-developed formula that’s free from crystalline silica and propylene glycol, which many pet owners look for in safer litter choices.
• Compatibility with most litter boxes, including regular pans and many automatic systems.

These attributes make PrettyLitter appealing if you want a practical, health-aware solution rather than a traditional clumping clay litter.

The quality of PrettyLitter is focused on convenience and health-focused performance. The silica gel crystals are durable and do a solid job at moisture absorption and odor suppression compared with many clay litters. Because it’s non-clumping, you won’t be dealing with pee clumps, which can be a pro if you prefer monthly full refreshes. The color-change feature is reliable enough to prompt timely veterinary checks, though it’s important to remember it’s a monitoring tool, not a diagnostic test.

The product is veterinarian developed and formulated to reduce dust and tracking, which helps maintain a cleaner environment for you and your cat. Some households report that the litter lasts reliably for a month per cat as advertised, but performance can vary with multi-cat homes, very heavy-using cats, or if you’re used to scooping urine clumps daily. Packaging and shipping of the 6 lb bag are convenient — you can stash it easily in a closet or under a counter.

Pros:

• Health monitoring with color-changing crystals gives you early alerts about urinary pH changes and possible blood.
• Lightweight and low tracking, making it easier to handle and help keep your floors clean.
• Advanced odor control through absorption and dehydration of waste, not masking.
• Low dust and veterinarian developed, free from crystalline silica & propylene glycol.
• Unscented option is good for sensitive noses and picky cats.
• One 6 lb bag is marketed as a one month supply for one cat — convenient for subscription or monthly replacements.

Cons:

• Non-clumping means you can’t scoop urine clumps; you’ll need to fully replace litter monthly or more often depending on usage.
• May be less cost-effective in multi-cat households where turnover is faster than one bag per month.
• Color changes are a helpful indicator but not a substitute for veterinary testing — false positives/negatives can occur.
• Some cats that prefer the texture of clay might take time to adjust to silica crystals.
• Because it’s absorbent rather than clumping, odors can concentrate if not refreshed on schedule in heavier-use setups.

If you value convenience, lightweight handling, and proactive health monitoring, PrettyLitter is a compelling option. If your priority is scoopable clumping action or you have multiple cats, you may need to weigh the monthly replacement schedule and cost against your household’s needs.

Comparison — At a glance

You’ve got four very different litters here. Below is a clear comparison of the specifications so you can quickly see which matches your needs and routine.

Specifications table

How to read the table (what the specs mean for you)

• Clumping vs non-clumping: If you prefer scooping and want solid clumps for easy removal, Boxie, Dr. Elsey’s, and ARM & HAMMER are clumping options. If you want lightweight, low-refill, and moisture-absorbing crystals with health alerts, choose PrettyLitter (non-clumping).
• Odor control style: Boxie uses probiotics to target odor-causing bacteria (a different approach than masking smells). ARM & HAMMER uses baking soda for chemical odor neutralization. Dr. Elsey’s relies on hard clumps and natural clay to trap odors. PrettyLitter traps and dehydrates moisture to reduce odor and also monitors pH.
• Dust & tracking: All the clay litters in this group advertise very low dust (99–99.9%). PrettyLitter doesn’t list a precise dust percentage but highlights low tracking and being lightweight—good if you want less scooping of tracked litter.
• Longevity: Boxie explicitly claims the longest-lasting performance per bag (30–40 days). PrettyLitter also claims ~1 month per cat from a 6 lb bag. The two 18 lb clay bags don’t provide exact day counts in the description.
• Health & special needs: If monitoring urine pH and early indicators (UTIs, blood, kidney issues) matters to you, PrettyLitter is the only one that changes color to flag potential issues. If you need a hypoallergenic or vet-approved formula, Boxie and PrettyLitter call out vet development/approval and hypoallergenic properties; Dr. Elsey’s highlights hypoallergenic, too.

Quick takeaways — which one might fit your routine?

• Choose Boxie if you want a modern, low-dust clumping clay with probiotic odor control and long bag life (good for busy households or if you want to change litter less often).
• Choose Dr. Elsey’s if you want classic, very hard clumping clay that’s reliable for single- or multi-cat scooping and minimal dust.
• Choose ARM & HAMMER if you like baking-soda freshness and a familiar clay clump formula with strong odor-neutralizing claims.
• Choose PrettyLitter if you want lightweight silica that reduces refills, provides strong moisture control, and gives you health-monitoring color feedback with each pee.

If you tell me which factors matter most to you (scent, dust sensitivity, automatic box, monitoring health, budget, how often you scoop), I can recommend the single best pick for your situation.

Conclusion

You’ve looked at four different litter options, and each brings strengths and trade-offs. Below is a concise wrap-up so you can pick the one that best fits your lifestyle, home, and cat.

Boxie Probiotic Cat Litter (16 lb)

• Summary: A clumping clay litter that uses odor-eliminating probiotics rather than perfumes. Low dust and fragrance-free.
• Drawbacks: You may pay a bit more than basic clay litters. Some users find clumps softer or less durable than traditional heavy clay clumps, and tracking can still occur.
• Recommended if: You want strong, chemical-free odor control with probiotic action and prefer an unscented option that’s kinder to noses.

Dr. Elsey’s Ultra Unscented Clumping Clay (18 lb)

• Summary: Known for firm clumps, very low dust, and being gentle on cats with respiratory sensitivities or allergies.
• Drawbacks: It’s heavy and a bit gritty for some cats; odor control is solid but not always as aggressive as baking-soda formulas in heavy multi-cat environments.
• Recommended if: You have a cat with allergies, respiratory concerns, or sensitive skin—and you want a reliable, low-dust unscented litter.

ARM & HAMMER Ultra Last Clumping Cat Litter (18 lb)

• Summary: Strong odor control thanks to baking soda, clumps well, and is affordable—good for multi-cat households.
• Drawbacks: Some cats may track it more; a few owners report slight dust during pouring and occasional scent from the baking-soda formula for sensitive noses.
• Recommended if: You need powerful odor control on a budget (especially in multi-cat homes) and don’t have severe sensitivity to baking-soda formulations.

PrettyLitter Health Monitoring Cat Litter (6 lb, non-clumping)

• Summary: Lightweight silica gel crystals that change color to help monitor urine pH and blood indicators; low tracking and designed to last about a month for one cat.
• Drawbacks: Non-clumping means you must fully replace the box regularly rather than scoop daily; it’s more expensive per month, and the color-change can sometimes be misleading. Some cats dislike the texture, and silica products aren’t ideal if your cat tends to ingest litter.
• Recommended if: You want a low-maintenance, lightweight option that gives you health-monitoring clues and you’re willing to pay a premium and change the box regularly.

Overall recommendation (who should pick which)

• If you want odor control without fragrances and like the idea of probiotic odor neutralizers: choose Boxie Probiotic.
• If your cat (or someone in your home) has allergies or asthma and you need a low-dust, dependable clumping litter: choose Dr. Elsey’s Ultra Unscented.
• If you manage a multi-cat household and need strong, budget-friendly odor control: choose ARM & HAMMER Ultra Last.
• If you prioritize health monitoring, light weight, and low tracking and don’t mind replacing the entire box monthly: choose PrettyLitter.

If you’re still unsure, think about the top priorities for you and your cat—scent sensitivity, dust, odor control, cost, and whether you want health monitoring—and choose the product that aligns with the most important items on that list.
