Clay litter clumps because sodium bentonite swells and locks together when it gets wet. Take the clay away and something else has to do that job, and the material you pick decides almost everything about how the box behaves: how heavy the bag is, how much dust hangs in the air, how far granules travel across the floor, and whether the clump survives the scoop. This shortlist of 7 non clay clumping cat litter picks from Arm & Hammer, World’s Best Cat Litter, SmartCat and more is organised by material for exactly that reason.

Our top pick is World’s Best Cat Litter Clumping Formula for its 100 percent corn granules, the longest-established plant binder and the one that behaves most like clay in daily use, at a published 99 percent dust free. If tracking is your main complaint, skip to the pellet litters. If fragrance is what you are escaping, check each variant carefully, because natural does not mean unscented.

Pros & Cons

Pros

  • Whole-kernel corn gives firm clumps that lift cleanly
  • Published 99 percent dust free, so pouring does not raise a cloud
  • Unscented, with odour control by absorption rather than masking
  • Manufacturer claims the bag lasts twice as long as ordinary litter
  • Mid-size granule tracks less than fine grass or pellet extremes

Cons

  • Faint corn smell for the first day after a fresh pour
  • Costs more per pound than commodity clay litter
Detailed Review

If the reason you are leaving clay is dust and weight, but the thing you are afraid of losing is clump strength, this is the litter that solves both. Whole-kernel corn clumps by starch gelatinisation: the granule absorbs moisture, the starch swells, and neighbouring granules bind into a mass firm enough to lift in one piece. Among plant materials nothing else comes as close to bentonite.

Granule size is the underrated part. It sits in the middle of the range, which is exactly where tracking is lowest. Very fine litters wedge into paw pads and very light ones get kicked out of the box; a mid-weight granule mostly stays where you poured it.

Two honest notes. There is a faint corn smell on the day you refill, which fades. And it costs more per pound than clay, though the practical gap narrows because plant litter is lighter for the same box volume, so a smaller bag fills the same box.

Bottom line: the default recommendation for anyone switching away from clay who does not want to compromise on the scoop.

Specifications
  • Material: 100 percent corn
  • Clumping: yes, quick clumping, starch-bound
  • Bag size: 28 pounds
  • Scent: unscented
  • Dust: 99 percent dust free as published
  • Formulation: multiple cat
  • Manufacturer claim: lasts 2X longer
How to Use

Fill to at least three inches. Corn needs depth to finish binding before liquid reaches the box floor, and a shallow box produces cakes stuck to the plastic rather than clumps.

Scoop daily and top up to keep the depth constant rather than waiting for the level to drop. Constant depth is what keeps clump quality consistent through the life of the box.

Who It Is For

Households switching from clay who want the change to be invisible in daily use. Also a strong pick for multi-cat boxes, where clump firmness matters most because the box is worked harder.

Less ideal for a cat that eats litter, where a pellet format is safer, and for anyone who genuinely wants the lightest possible bag.

Pros & Cons

Pros

  • Published as 50 percent lighter than clay for the same number of uses
  • Stated to absorb twice the urine of clumping clay litter
  • Corn fibres, baking soda and plant extract for odour elimination
  • Formulated and rated for multi-cat use
  • Easiest plant litter here to find and restock

Cons

  • This is a Fresh Scent formula, not an unscented one
  • Dust control relies on added mineral oil rather than on a dust-free grain
Detailed Review

This is the plant litter you can buy anywhere, and availability is a genuine feature rather than a consolation. A litter your cat accepts and you cannot reliably restock is a litter you will end up switching away from, and switching is the part cats object to.

The formulation is corn fibres plus baking soda plus a plant extract, and the two figures Arm and Hammer publishes are the useful ones: it absorbs twice the urine of clumping clay litter, and it is 50 percent lighter than clay for the same number of uses. That second number is the clearest statement of why people move away from clay in the first place.

Two things to be clear about. This particular product is a Fresh Scent formula, so it is not the litter to buy if fragrance is the thing you are escaping. And its low dust claim is achieved with added mineral oil for dust control rather than by the grain being inherently dust free, which is a legitimate approach and worth knowing.

Bottom line: the sensible default for most households on cost and availability, provided you are happy with a scented litter.

Specifications
  • Material: corn fibres with baking soda and plant extract
  • Clumping: yes
  • Bag size: 18 pounds
  • Formulation: multi-cat
  • Absorbency: absorbs 2X the urine of clumping clay, as published
  • Weight: 50 percent lighter than clay for the same number of uses, as published
  • Dust: low dust, using mineral oil for dust control
  • Scent: Fresh Scent
Who It Is For

Multi-cat households and anyone who wants a plant litter available at an ordinary supermarket rather than only online. Also a reasonable first step for owners testing whether their cat accepts plant granules at all.

Not the choice for a scent-sensitive cat or owner, since this variant is fragranced. SmartCat and sWheat Scoop are the fragrance-free options in this list.

Care and Safety

Scoop daily and refresh the full box every two to four weeks. Plant granules break down as they absorb, so the fine material at the bottom accumulates faster than with clay.

Wash the box with unscented soap. Residual perfume in the plastic is a common and easily missed reason a cat starts avoiding a clean box.

Pros & Cons

Pros

  • Odour-neutralising enzymes work without added fragrance
  • Published 99.5 percent dust free, the highest figure in this group
  • Low tracking claim alongside the dust figure
  • Clumps twice as fast as the brand's original formula, as published
  • One 25 pound bag stated to last 63 days for one average 8 pound cat

Cons

  • Flushable only where local rules allow; the bag states do not flush in California
  • Clumps soften if left in the box for several days rather than scooped daily
Detailed Review

Wheat sits between corn and the softer plant materials. The starch does the clumping and the manufacturer states that naturally occurring enzymes in the wheat neutralise odour, which is a different mechanism from masking with fragrance. For households where scent is the problem rather than the solution, that distinction is the whole reason to consider this litter.

The published numbers are unusually good. It claims 99.5 percent dust free, which is the highest dust figure among the litters here, low tracking alongside it, and clumping twice as fast as the brand's own original formula. It also gives a usable duration figure rather than a vague one: one 25 pound bag stated to last 63 days, based on the average absorbency associated with one healthy 8 pound cat.

The footnote worth reading is on flushing. The bag says flushable and then adds that you should not flush it in California and should dispose of it in the trash, which is a useful reminder that this property is regulated locally rather than being a universal permission.

Bottom line: the pick if unscented odour control and low dust are your priorities, and you scoop every day.

Specifications
  • Material: wheat
  • Clumping: yes, stated 2X faster than the brand's original formula
  • Bag size: 25 pounds
  • Duration: stated 63 days for one healthy 8 pound cat
  • Odour control: naturally occurring enzymes
  • Dust: 99.5 percent dust free as published
  • Tracking: low, as published
  • Flushable, except where local rules prohibit it, including California
How to Use

Scoop every day. Wheat clumps are at their firmest within the first twenty four hours and lose integrity after that, which is the main way people conclude wheat does not clump.

Check your local rules before using the flushable claim. The bag itself says do not flush in California and dispose in trash, and other jurisdictions have similar restrictions.

Who It Is For

Owners of scent-sensitive cats, households with someone who reacts to fragranced litter, and anyone whose cat has already rejected coarser granules.

Less suitable for people who scoop every other day, and worth avoiding if anyone in the house has a wheat allergy severe enough to react to airborne flour dust.

Pros & Cons

Pros

  • Softest and most sand-like footing here, good for kittens and sensitive paws
  • 100 percent grass seed, non-GMO Project verified and made in the USA
  • Fragrance free and clay free with no added dyes
  • Published 99 percent dust free
  • Brand claims it out-clumps clay, which is unusual confidence for a plant litter

Cons

  • Fine granules track further than mid-size litters or pellets
  • Light material gets kicked out by enthusiastic diggers
Detailed Review

Grass seed is the material to reach for when the cat, not the owner, is the constraint. SmartCat describes the texture as soft and sand-like and recommends it specifically for a new kitten or a cat that is particular about its paws, and that is exactly how it behaves. Cats that refuse coarse litter often accept it immediately.

It clumps far better than a soft fine litter has any right to. The brand prints Out Clumps Clay Every Day on the bag, which is a bold claim for a plant material and is at least plausible given how tightly fine granules pack around moisture. The rest of the sheet is straightforward: 100 percent grass seed grown in the USA, non-GMO Project verified, fragrance free, clay free, 99 percent dust free.

The cost of fine and light is tracking. These granules lodge between toe pads and travel, and an enthusiastic digger will spray them past the box lip. A high-sided box and a mat under it are close to mandatory here rather than optional.

Bottom line: the best texture in this list and the worst tracking, which is a fair trade if your cat is the one being difficult.

Specifications
  • Material: 100 percent grass seed, grown in the USA
  • Clumping: yes; brand claims it out-clumps clay
  • Bag size: 20 pounds
  • Grain: very fine, sand-like
  • Additives: fragrance free, clay free, no dyes
  • Dust: 99 percent dust free as published
  • Certification: Non-GMO Project verified
  • Recommended depth: 3 to 4 inches
Who It Is For

Cats with sensitive paws, declawed cats, cats recovering from surgery, and any cat that has rejected other plant litters on texture grounds.

Not the pick for a household already fighting a losing battle with tracking, unless you are prepared to add a high-sided box and a proper litter mat.

Care and Safety

Use a covered or high-sided box if your cat digs. This material is light enough to leave the box under its own momentum.

Vacuum the surrounding area rather than sweeping; fine granules scatter when swept and settle again a metre away.

Pros & Cons

Pros

  • Cassava binder gives firm clumps at a lower weight than pure corn
  • Small grain sits between fine and mid-size on tracking
  • Stated to be virtually dust free
  • Biodegradable plant blend
  • Handles multi-cat loads without collapsing

Cons

  • Less widely stocked than corn-only or supermarket brands
  • Small grain still tracks more than a pellet
Detailed Review

The interesting idea in this litter is the blend. Corn brings clump strength, cassava starch brings binding at a lower material weight, and the result is a small-grain litter that behaves more firmly than its weight suggests. If pure corn feels heavy to you but pea husk feels too soft, this is the middle position.

Grain size is deliberately small rather than fine, which is a distinction worth making. Fine litters such as grass seed maximise softness and tracking; a small grain keeps most of the clump quality of a mid-size granule while feeling gentler underfoot.

Availability is the weakness. This is not a litter you will find at every supermarket, and running out mid-week means either a substitute your cat has to accept or a rush order. Buy the larger bag if you settle on it.

Bottom line: the best-balanced litter here on the axis that matters most, clump strength against weight, provided you can restock it reliably.

Specifications
  • Material: corn and cassava blend
  • Clumping: yes
  • Grain: small
  • Dust: stated virtually dust free
  • Scent: unscented
  • Formulation: suitable for multiple cats
Who It Is For

Owners who found pure corn heavy and lighter litters too soft, and anyone prioritising low dust for their own respiratory comfort as much as the cat's.

Less suitable if you rely on picking litter up during a supermarket run, since this is largely an online purchase.

How to Use

Keep the box at three inches or more. Small-grain litters compact more than coarse ones, so the depth you started with drops faster than you expect and needs topping up.

When switching from a coarse litter, mix over at least a week. The grain size change is more noticeable to a cat than the material change.

Pros & Cons

Pros

  • Pellet format tracks less than any granule in this list
  • Corn in the blend firms up clumps that pure tofu leaves soft
  • Very low dust, both when pouring and when the cat digs
  • Light bag for the volume it fills
  • Dissolves rather than shattering, so clumps stay together

Cons

  • Some cats refuse to stand on pellets and need a slow transition
  • Softer clumps than corn granules if left more than a day
Detailed Review

Tofu litter is extruded soy fibre, and it behaves unlike every granular litter in this list. The pellets dissolve into a soft mass rather than binding into a hard clump, which sounds worse and in practice scoops perfectly well provided you do it daily. Blending corn into the mix, as this product does, firms that mass up considerably.

The reason to choose it is tracking. A pellet is simply too large to lodge in a paw pad, so what leaves the box is the occasional pellet you can pick up rather than a trail of grit through the hallway. For flats and for anyone with hard floors, that difference is the whole argument.

The risk is acceptance. Cats that grew up on fine litter often dislike standing on pellets and will express that opinion somewhere inconvenient. Transition slowly, and if you have a second box, run pellets in one and the old litter in the other for a while.

Bottom line: the lowest-mess option here by a wide margin, if your cat agrees to it.

Specifications
  • Material: soy fibre with corn blend
  • Format: extruded pellets
  • Clumping: yes, dissolving clump
  • Bag size: 18 pounds
  • Dust: low
  • Scent: unscented
Who It Is For

Small homes, hard floors, and anyone whose main complaint about litter is finding it three rooms away. Also a sensible choice for kittens who mouth everything, since pellets are harder to ingest accidentally than fine grit.

Not the first choice for a fussy adult cat with an established preference for fine litter.

How to Use

Run a slightly shallower bed than you would with granules, around two to three inches. Pellets do not need the same depth to bind because the clump forms by dissolving rather than by packing.

Scoop daily. A dissolved mass left for two days spreads sideways through the surrounding pellets and becomes harder to lift cleanly.

Pros & Cons

Pros

  • Pellet form tracks far less than any granule in this list
  • Published 99 percent dust-free and low-tracking on the same panel
  • Stated to absorb up to three times its own weight
  • Manufacturer claims tighter clumps that use less litter per scoop
  • Made from recycled pea husks and stated 100 percent biodegradable

Cons

  • Sold in vanilla and lavender scented varieties rather than fragrance free
  • Some cats refuse to stand on pellets and need a slow transition
Detailed Review

Pea husk is a by-product of pea processing, and the thing most write-ups get wrong about it, including our first pass, is the form. This is not a light loose granule. Catit extrudes it into pellets around 1.5 millimetres across, and that changes almost everything about how it behaves in a box.

Pellets are too large to wedge into a paw pad, which is why the packaging can advertise 99 percent dust-free and low-tracking together rather than trading one against the other. The absorbency figure is the other headline: the manufacturer states the pellets take up to three times their own weight, and that the resulting clumps are tighter and use less litter per scoop, so a box goes further than the bag weight suggests.

Two honest notes. It is sold in vanilla-scented and lavender-scented varieties rather than as a fragrance-free litter, so it is not the pick for a scent-sensitive household. And pellets are a texture some cats simply refuse, so transition slowly and keep a second box with the old litter available.

Bottom line: the lowest-mess litter here if your cat accepts pellets, and a lighter box to carry than any bag in this list.

Specifications
  • Material: recycled pea husk
  • Format: extruded pellets, approximately 1.5 mm diameter
  • Clumping: yes, stated to clump without sticking to the box
  • Absorbency: up to 3 times its own weight, as published
  • Dust and tracking: 99 percent dust-free and low-tracking, as published
  • Box size: 12.3 pounds
  • Scent: available in vanilla-scented and lavender-scented varieties
  • Biodegradable: stated 100 percent
Who It Is For

Households with hard floors and anyone whose main complaint about litter is finding it three rooms away. The pellet form is also easier on people carrying litter, since the box is the lightest here.

Not the choice for a scent-sensitive cat or owner, given the vanilla and lavender varieties, and not the first pick for a fussy adult cat with an established preference for fine litter.

Care and Safety

Run a slightly shallower bed than you would with granules, around two to three inches. Pellets bind by absorbing rather than by packing, so extra depth adds less than it does with a fine litter.

Scoop daily. Catit says the clumps do not stick to the box, which makes scooping easy, but a mass left for two days spreads sideways through the surrounding pellets and becomes harder to lift cleanly.

How to Choose Non Clay Clumping Cat Litter

Every bag in this category says natural, lightweight and low dust. Those words are close to meaningless on their own. What actually differs is the plant the granule is made from, and each one has a distinct failure mode.

What Leaving Clay Behind Actually Changes

The first difference is weight. Clay is dense; plant fibre is not. Arm and Hammer states the gap plainly on its Naturals bag, claiming the litter is 50 percent lighter than clay litter for the same number of uses, which is why these bags are sold in 12 to 25 pound sizes while clay is sold in 40 pound jugs. If carrying litter up stairs is part of your life, that is the single biggest quality-of-life change.

The second is dust. Clay dust is fine crystalline silica-bearing mineral dust, and the cloud that rises when you pour a bag is the reason many owners switch. Plant granules produce far less airborne dust, though they are not dust free; wheat and corn both throw a fine starch powder, and the difference is that starch settles quickly rather than hanging.

The third is what happens after the scoop. Clay is inert mineral that goes to landfill and stays there. Plant litters are biodegradable in principle, which does not mean you should put used litter in a garden compost heap; cat waste can carry parasites and belongs in municipal waste unless your local authority says otherwise.

The Plant Materials and How Each One Clumps

Corn is the most common. Whole-kernel corn granules clump through starch gelatinisation: the starch absorbs moisture, swells and binds neighbouring granules into a firm mass. Corn has the longest track record for firm clumps among plant materials and holds a scoop well. World’s Best and the corn blend in FUKUMARU both work this way.

Wheat works similarly but adds enzymes. sWheat Scoop states that its wheat contains naturally occurring enzymes that neutralise odour rather than masking it, and the starch handles clumping. Wheat clumps are slightly softer than corn and more prone to crumbling if left several days.

Grass seed is the outlier. SmartCat uses 100 percent grass seed grown in the USA and produces a very fine, sand-like granule that is notably soft under paws, which matters for kittens, declawed cats and cats recovering from surgery, and the brand is confident enough about the binding to print Out Clumps Clay Every Day on the bag. Pea husk, used by Catit, is not a loose granule at all: it is extruded into pellets around 1.5 mm across, made from recycled pea husks, which the manufacturer says absorb up to three times their own weight and produce tighter clumps using less litter. Cassava appears as a binder in blended litters such as Sustainably Yours, where it is combined with corn to get clump strength without the weight.

Tofu litter is the newest category and behaves differently from all of the above. It is extruded soy fibre in pellet form, it dissolves rather than crumbling, and it is the material most often marketed as flushable. FUKUMARU blends soy with corn to firm up the clump, which is the usual fix for pure tofu litter being slightly too soft.

Clumping Strength and Whether the Scoop Survives

A clump that breaks apart on the scoop is worse than no clumping at all, because the fragments spread through clean litter and the box turns over faster. Firmness depends on the binder and on how quickly the granule absorbs, and it also depends on litter depth. Three inches is the working minimum for any clumping litter; at two inches the urine reaches the box floor before the granules have finished binding and you get a flat cake stuck to the plastic.

Resist the urge to rank the materials in a single line, because the manufacturers’ own claims contradict any such order. Corn is the material with the longest track record for firm clumps, and it is the safest bet. But SmartCat claims its grass seed out-clumps clay, sWheat Scoop claims its wheat clumps twice as fast as its own previous formula, and Catit claims its pea husk pellets form tighter clumps than a comparable mineral litter. Those are all plausible and none of them are measured on a common test.

What does hold across the category is a difference of form rather than of plant. Fine and mid-size granules bind by packing tightly around moisture, so their clumps are firm but can crumble at the edges if left for days. Pellet litters, including pea husk and tofu, dissolve into a soft mass rather than shattering, which scoops perfectly well provided you do it daily. Pick by form and by how often you scoop, not by a league table.

Tracking, Grain Size and Where the Litter Ends Up

Tracking is mostly a function of grain size. Very fine granules such as grass seed lodge between toe pads and get carried out of the box, which is the price of that soft sand-like texture. Mid-size granules such as corn sit in the middle and generally stay put.

Pellet litters track least of all because a pellet is too large to wedge into a paw, and both Catit and the tofu blends here are pellets rather than granules. Catit advertises 99 percent dust-free and low-tracking on the same panel, which is consistent with the form rather than with the raw material being light. The trade is texture: some cats dislike standing on pellets and will tell you so by using the bath mat. If you are switching a fussy cat, a fine or mid-size granule is the safer bet even though it tracks more.

Odour Control Without Piling On Fragrance

Plant litters generally control odour by absorbing and by hosting enzymes or starch that interfere with ammonia formation, rather than by masking. That is a genuine advantage for cats sensitive to scent. It is not, however, a promise that plant means unscented: Arm and Hammer Naturals in this list is a Fresh Scent formula, and Catit Go Natural is sold in vanilla and lavender scented varieties. If fragrance is the thing you are escaping, check the specific variant rather than trusting the word natural, because unscented plant litter smells faintly of the plant and corn smells like corn on a warm day.

Baking soda appears in several formulas as an alkaline buffer against acidic odour compounds. It is legitimate chemistry and it is also not magic; nothing substitutes for scooping daily. If odour is your main problem, increase litter depth and scoop frequency before you change brands.

Flushing, Composting and What the Bag Can Actually Promise

sWheat Scoop panel showing low tracking, flushable and 99.5 percent dust free claims
Photo: Amazon

Several plant litters state that clumps are flushable, and the small print underneath is the part worth reading. sWheat Scoop prints Flushable on the front and then adds, in a footnote on the same panel, do not flush in California, dispose in trash. That is not a manufacturer being cautious for the sake of it; several jurisdictions restrict it because wastewater treatment is not designed to inactivate certain parasites, and septic systems handle added solids poorly. Treat flushability as a property of the material rather than as permission, and check your own local rules.

Composting has the same caveat and a stricter one. Home compost heaps rarely reach or hold the temperature needed to make cat waste safe, and compost from a heap that received cat waste should never touch a vegetable bed. The environmental case for plant litter is mostly about the material being renewable and the bag being lighter to ship, which is real, rather than about the used litter being garden-ready.

Litter is only half of a cat’s digestive and urinary picture; diet is the other half, and our guide to vet recommended wet cat food covers hydration, which directly affects how much urine ends up in the box. If you are comparing against conventional options, our scoopable cat litter guide covers the clay side.

Why You Should Trust Us

We check every product against its current listing before it goes on a list, and in this category that check does real work. Searches for non clay clumping litter return a large number of clay products, because the phrase clumping cat litter appears on almost every bag and the word clay appears on almost none. Several of the highest-selling results for this term are sodium bentonite litters. We removed all of them, along with non-clumping crystal and paper litters, which are non clay but do not clump.

What is left is seven litters that are genuinely both: plant-derived and clumping. We read the critical reviews for each and the complaints cluster predictably by material, which is why the cons in each entry are material-specific rather than generic. A wheat litter and a pea husk litter fail in different ways, and saying so is more useful than saying both are natural.

Final Thoughts

Best overall is World’s Best Cat Litter Clumping Formula. Corn is the plant binder with the longest track record for holding a clump together, which is the property that most determines whether a litter feels like an upgrade or a compromise, and at a published 99 percent dust free with a mid-size granule it is the sensible middle ground on both dust and tracking.

Best value is Arm and Hammer Naturals Clumping Cat Litter. It is the easiest of these to find, it is formulated for multi-cat use, and it clumps well enough that most households switching from clay will not feel like they gave something up.

For specific situations, pick by material. SmartCat grass seed is the softest underfoot and the right answer for a cat with sensitive paws. FUKUMARU tofu pellets track the least and are the pick for anyone tired of finding litter in the hallway. Catit pea husk pellets are the pick if tracking is your main complaint, and the box is the lightest here to carry. sWheat Scoop is the choice if fragrance is the thing you are trying to escape, and Sustainably Yours is the compromise that keeps corn clump strength at a lower weight. More pet picks are in Pet Supplies, and everything new is in our latest articles.

Non Clay Clumping Cat Litter FAQs

Does non clay litter really clump as well as bentonite?

Corn comes closest and, at adequate depth, is difficult to distinguish from clay in daily use, and SmartCat goes further and claims its grass seed out-clumps clay outright. Pellet litters such as pea husk and tofu behave differently rather than worse: they dissolve into a soft mass instead of setting hard, which scoops cleanly if you do it daily. Depth matters more than brand: below about three inches, every clumping litter in this category will stick to the box floor.

How do I switch my cat to non clay clumping cat litter without a protest?

Mix gradually over a week to ten days, starting at roughly one quarter new litter and increasing every few days. Cats object to sudden texture changes more than to smell. If your cat starts eliminating outside the box, go back a step rather than pushing through, and consider a second box with the new litter so there is always a familiar option.

Is corn-based litter safe if my cat eats a little?

Small incidental ingestion of plant litter is generally less concerning than ingesting clay, which does not break down. That said, a cat that deliberately eats litter is showing a behaviour worth a vet visit, since it can indicate a dietary deficiency. Kittens who eat everything are usually better started on a pellet litter, which is harder to swallow accidentally.

Why does my plant litter smell different from clay in 2026?

Because it is not masking anything. Clay litters usually carry fragrance; unscented plant litters smell faintly of their raw material, so corn smells like corn and wheat smells like a grain store. That baseline scent fades within a day of pouring. If you are getting ammonia instead, the issue is depth or scoop frequency rather than the litter itself.

How often should I change the whole box?

Scoop daily and top up to keep depth constant, then do a full change roughly every two to four weeks depending on the number of cats. Plant litters generally need full changes slightly more often than clay because the granules break down as they absorb. Wash the box with unscented soap and dry it completely; residual fragrance in the plastic puts some cats off. Diet affects this too, and our all life stages cat food guide covers the hydration side.
