"I get commissions for purchases made through links in this post."


If you have a cat, you probably want to consider one of the best sifting litter boxes on the market. These boxes are convenient and space-saving and can catch the clumps from your cat’s litter box without messing up your carpet or clothes. These boxes may come with hoods that can trap bad smells and come with antimicrobial features. You should look for one that combines a sifting tray with a wood pellet litter. The pellets will fall through the sifting layer and get absorbed by a removable cat pad in the drawer. This type of litter is ideal for wood pellets and pine pellets. It also doesn’t take up much space, making it a great choice for large cats.

If you want a sifting litter box for your cat, you probably want to read our reviews and see how well these units work.

#1. Petmate Arm & Hammer Sifting Litter Pan

Petmate Arm & Hammer

Dimensions 19″ L x 15″ W x 8″ H
Color Light Gray/Dawn
Compatible Litter Clumping litter, A&H Slide Litter, Feline pine, Wood/Walnut shell pellets

Buy it on Amazon

Petmate has established a name through its dog kennels and crates. Yet, being a lead player in the pet care industry with multiple merge acquisition deals, it surely cannot leave out the thriving market for cats.

Open-top design

While you would love a high-edged or hooded kitty litter box for your kicking baby, open-top pans are still in high demand for novices or parents with senior cats.

In fact, according to Dr. Ernie Ward’s publication on Pet Health Network, cats don’t specifically have a preference toward litter box types as long as the contents are clean to please their senses.

Petmate Arm & Hammer is simple to maintain and clean, and since the rim is moderately high, chilled senior cats would also fall in love with the product.

Reinforced polymer three-layer construction

There are three pans coming with one unit, one sifter, and two solid trays. First, you pour the contents into the top solid pan. The sifter is nestled between the other two and is only taken out when you feel the urge to filter out the soiled litter.

By alternating between the two solid trays, you won’t overwork them, thus the lifespan of the trays is actually being prolonged while the odor is also limited as you didn’t allow bacteria to stock on one particular tray for long. To add, the overall reinforced plastic is a chef’s kiss against scratches and heavy load.

Flexibility for DIY adjustments

This unit not only works well on its own, but it also fits into other covered litter box models. You can nest it inside an extra-large hooded litter pan with no problems, or you can toss it inside a self-trimmed tote to prevent spillages.


In 2018, maybe there were some bad raps about the bacteria gimmicks between the brand and the National Advertising Division (NAD) of the Better Business Bureau, yet you should be aware that anti-microbial coating isn’t due for bacteria-free surfaces, but to boost the lifespan of the litter.

On a different note, if you want to increase the space between the sifter and the solid pans, just foam-pad the sifter’s edges. It can escalate up to 1 ich.

  • Simple, open view for 24/7 inspection
  • Easy to scoop and sift at any time
  • Flexible usage settings
  • A bit small for big cat breeds or multiple cats
  • Too narrow between the sifter and the solid pans

#2. Purina Tidy Cats BREEZE Hooded Litter Box Starter Kit

Purina Tidy Cats BREEZE

Dimensions 20.5″ L x 16.8″ W x 16.5″ H
Color Gray
Compatible Litter Wood/Walnut-shell/Breeze pellets

Buy it on Amazon

The model we’re reviewing is the hooded version, but thanks to the insightful marketing and customer service tactics of Purina, there is also an open-top with high walls and extra-large versions within the same Breeze line.

Anti-tracking pellet sifting tray

If you are a nature lover and despise tracking clumping litter, or by a more precise portrait, a pellet enthusiast, then this Breeze system will become your true love.

The instant filtering net would undoubtedly please your cat if he suffers distress from securing the body while urinating since the pellets would crumble into sawdust and send the waste straight to the padded grate via the slats. This would, in turn, prevent the cat from sitting and reeking in urine if he’s a clumsy boy.

Odor absorbent pads

And don’t freak out if you see the hood on the image yet. This lid definitely more or less would trap a faint level of pungent smells, but the majority of them are brushed off with the lumber odor of pellets and pinned down by the repellent and absorbent pads.

If your cats refuse to switch to pellet litter since they’re used to World Best clumping litter or silica crystals, allow them to have a moment for breaking in.

A scoop bundle

Having a scoop alongside the whole package is a win-win situation for both Purina and the most smell-sensitive consumers. No matter what the marketing gimmicks may claim, pellets and fecal matter just don’t go together.

Actually, stool won’t crumble into sawdust coming into contact with wood pellets but hide among them and disperse a lingering ammonia odor noticeable to sensitive noses. This is when you need a slotted shovel to scoop out the feces daily.


If you’re having trouble with how hard it is to find Breeze pads for the receptacle compartment in your local dollar trees or supermarkets, you can consider replacing them with the regular puppy pee ones.

  • Extend the lap between each complete pellet dumping and the whole unit cleansing to three-four weeks
  • No tracking litter around the house
  • The design of the top fitting over the bottom edge, not inside which allows side spillages
  • The Breeze pellets don’t absorb odor well and run out faster than normal pine pellets/equine bedding

#3. Petmate Corner Sifting Litter Pan

Petmate Corner Sifting

Dimensions 26″ L x 19″ W x 11.7″ H
Color Pearl Silver
Compatible Litter Clumping litter, Arm & Hammer Platinum Slide litter, Kiln dried pellets (Tractor Supply’s Equine Pine Bedding or Feline Pine)

Buy it on Amazon

Room-saving isosceles right triangle shape

This Petmate’s product is a match made from heaven with any shy ball that prioritizes low traffic when relieving him/herself or any cat custodian who wants to conceal their children’s chamber pots out of the guests’ sight.

The balanced cheese slice shape can be tugged inside your wardrobe or bathroom cabinet or turned against wall corners, which obviously doesn’t take as much space as a rectangular litter box.

Additionally, the “corner” with high back and rims concept has always been a hit left and right with bunny or guinea pig parents as well, since they can fit snugly into a pet cage and serve side-smearing pets well.

Patented sifting technology

One of the things that glorified Petmate as a lead player in the pet care industry was the fact that they introduced the first sifting litter box to the world.

This system isn’t 100% flawless, it has faced multiple ups and downs. Yet, the idea was brilliant, at least to a corner litter pan, since finding out a spade that conquers every sharp angle is such a pain in the neck.

High side – Low entry profile

This standard corner sifting litter box may build one of the highest walls among all of its uncovered cousins here, which implies its competency to fence against sided flying litter and urine.

But let’s talk about the half-moon entrance! It’s so incurvate despite such lofty sides, which makes the unit versatile for a variety of cat breeds and available to both the seniors and kiddos.


If being pretty and space-saving are the strongest points of a corner sifting litter box, then the hard quest to uncover which accessory would be the best to flatter this polished look, in the long run, is a huge let-down.

You can catch this problem clearly when searching for a standard square litter mat that can cover every space on the floor underneath a triangle pan or an off-the-peg liner that resembles a cheese slice.

  • Durable plastic resin material
  • Can fit into a tight space without looking awkward and obnoxious
  • Spacious hollow room to big cat breeds
  • The litter-filled pan is hard to grip and heavy to lift
  • A bit overwhelming to fit inside a cat cage

#4. SiftEase Litter Box Cleaner Sifter

SiftEase Litter Box Cleaner Sifter

Dimensions 14.5″ L x 7.5″ W x 16.8″ H
Color Navy Gray
Compatible Litter Clumping litter

Buy it on Amazon

An isolated labor-saving sifting basket

No one would want to host a face-to-face confrontation with stool and urine every single day while constantly bending down. With this spacious SiftEase individual sifting basket, you can escape the vicious cycle while separating clean and soiled litter all around the house within 5 minutes.

One may ask why just not get a complete sifting litter box. Because if you house multiple cats, you would have to take in x2 pans with every unit you buy. Imagine the amount of work you’d have to pour into cleaning a whopping 10 pans if you have four cats (following the n+1 rule: n cats + 1 extra litter box)!

On a side note, since this sifter is kind of an accessory, it would make a perfect birthday or Christmas present choice for cat lovers.
An enclosed recycle bin

You’ll get a 16.8-inch bin coming along, and it’s more than enough to contain the contents of over five litter boxes at once. Afterward, you can divide the filtered contents into each pan as usual. It’s simple but time and labor-saving at the optimum.

Side grip

Most sifting litter boxes offer a grid without grip so that it can be clipped between or inside the solid trays as a compact unit. Since this product intended to shed the limelight on the sifter solely, SiftEase engineers have placed stress on user-friendly features in lieu of pretty design.

The grip would make a big help for over-60-year-old grannies or folks with flabby arm muscle, as from now on, they won’t have to lift the slippery rims to lift the sifting basket on anymore.


Being an accessory itself, it’s pretty ironic that the thing can create a huge mess without other accompanies.

The first things you may find accommodating after a few initial trials of the SiftEase basket are some biodegradable or plastic bags to line the interior, since the bin may be overweight to some flabby arms.

On top of that, there’s also another critical technical failure: the slots that score up to ¼” in measurements. This makes them oversized and unappealing to a variety of litters from pine pellets to non-clumping crystals to stay clear over the sifter.

  • Reduces time compared to scooping
  • Sturdy build with heavy-duty plastic construction
  • Massive recycle bin
  • On the pricey side
  • The trash bin should have incorporated handles as well to make it more convenient to pour the clean used litter back into the sand pans

#5. Catit SmartSift Self-Cleaning Litter Box

Catit SmartSift Self-Cleaning Litter Box

Dimensions 26″ L x 19″ W x 25″ H
Color Tan
Compatible Litter Clumping litter

Buy it on Amazon

Motorless automated sifting lever

Catit has put its name on the map with the blue LED flower fountain model, which in turn gives it more credibility for its lines of cat toys and cat litter pans.

For this SmartSift kitty litter box, the highlight is its eco-friendly mechanical sifting technology. The unit involves no electricity via the way you hand-pull the lever gradually and it works like a toilet flush. The sifter then swivels and pours the fecal or urinated clumps down a drawer compartment, while the clean granules sway back into the grate.

The motorless concept, in a way, suits cats that get intimidated by noise easily, and we all love the idea of keeping our cats away from getting electrocuted, without a doubt.

Dual custom-fit biodegradable liners

Your cat’s pee pee can form a permanent foul odor when coming into contact with plastic surfaces, so it’s natural to seal the top with liners. It seems that Catit engineers have done their research intensively via the way we get a biodegradable finish on top of the receptacle compartment straight from the warehouse.

Yet if your cats love to dig their way to China, the liners wouldn’t be able to withstand all the scratches, leading to a scarred and unreturnable litter box. In this event, consider investing in scratch-proof tough liners/pads. They’re great in unlocking the implicit power of the Breeze system.

Smart access orifices

The easy-to-access maintenance door, the transparent inspection window, and the carefully marked biodegradable liners have made a dream team in keeping the cost of maintenance minimal in the long run.

Through a clear view from the top, you can easily shove a scoop inside to discard all the feces once a fortnight. To add, replenishing the clumping litter can also be done after a rotated sifting session without the need to detach any part via the maintenance door.

The best present? Since the amount of litter is kept in check effortlessly through a clear view, combined with the tagging liners clearly marked to determine the maximal level of litter appropriate to fill for a smooth operation, now you can run a 33lb kitty litter bag in three months in lieu of every month.

Removable swinging door

Many have given a frown upon the entrance being built too high off the floor, which makes it seem impossible for newborn kittens or senior arthritic cats to hop in.

In response, Catit reassured their customers by suggesting they install a sturdy tiny stair for them to step up and down or, more conveniently, dismantle the swinging door for a broader entry point.


This is where things start to turn sour for Catit, the deceptive massive build. The overall dimensions stated on the description box seem more than enough, but with just 19″ L x 13″ W x 17″ H interior before being shrunk any further by the sifter, no big fat cat, not even the slimmest Ragdoll or Maine Coon, can squeeze his plumpy tummy into the door.

Another thing to note, when the litter gets shattered all over the bad line or the grate, you can still cast an extra shovel. Or you can abide by Catit’s instructions and give the whole unit a few taps to cut down time and labor.

  • Catit offers newsletter subscribers chances for product tests and maintenance
  • Helpful if you’re on the go for a week or two
  • Poor fitment
  • Flimsy build since the unit can be dislodged if the cat accidentally hits the top container if you forget to lock the handle

#6. Luuup Litter Box


Dimensions 20.2 x 15.4 x 7.5 inches
Color White Green
Compatible Litter Wood/Walnut-shell/Equine/Feline pine pellets, Clumping litter

Buy it on Amazon

Compact reinforced plastic construction

Considering the heavy-duty plastic construction on its own, we have to say that Luup has successfully passed its legacy of being the most reputable dog crate manufacturer onto its cat litter pan line.

The design is sleek and compact, quite among the top tiers in terms of aesthetics and durability. The reinforced plastic solid pans are rustproof and definitely not the easiest for your felines to scratch on.

Undoubtedly, a Maine Coon of 12-15lbs would be squeezy freezy inside the pan, which makes the product unappealing to an entire large niche. Yet the litter box is cute and neat to pack along trips and holidays, while the hollow is not that small and can hold up to over 18lbs of litter.

Low entrance

The front rim is slightly dented to allow easy access for senior arthritis cats and newborn kittens. In combination with the low walls and the open-top design, your cats wouldn’t have to suffer from trapped stinky odor and internal fine dust (in case you use scoopable clumping litter) after each time you shake to sift.

Optimal ease to use

When you have something so simple and classic, three separate pans and nothing else, you won’t have to get involved with intricate cleaning routines or costly maintenance.

In this modern era, this Luup model fits right in with an apartment complex setting and won’t get your sewage system clogged midway.


As experienced cat parents have pointed out, the first generation open-top sifting pan design poses a threat to creating a dustier mess through shaking movements upon sifting. To shake, you’d need to lift the pan up first, so if your muscle is flabby, then, unfortunately, you and Luup just do not click well with each other.

To make the matter worse, the urine can flow through the strainer and form gross gelatinous lumps on the solid pan’s surface if your cats have too big a bladder or if the soiled litter hasn’t got enough time to dry.

  • Sturdy build
  • High-quality material
  • Simple to use, maintain, and clean
  • Low edges make it incompatible with sided peeing and kicking cats

The alternation between two solid pans encourages users to reduce the frequencies of surface wiping and used clean litter dumping, which potentially stocks bacteria.

#7. So Phresh Lift-to-Sift Litter Pan

So Phresh Lift-to-Sift Litter Pan

Dimensions 22.5″ L x 17.2″ W x 5.5″ H
Color Grey
Compatible Litter So Phresh odor control litter lines, Clumping clay litter, Silica gel crystals, Biodegradable litter

Buy it on Amazon

Compatible with various litter substrates

So Phresh is a pet care brand well-known for its wide range of odor control litter and hamster bedding. Thus, the company can definitely boast about an odor control line of litter boxes as well.

As litter is the chief product of So Phresh, it is second to none in mastering the science behind how litter granules, crystals, and pellets work and what suits them best. On this account, you can put your trust in the brand’s engineers when they claimed the sifter’s chameleon power against treating any litter substrate.

X-Large Built-In Sifter Pan

The grid is sandwiched between two regular litter trays, reminiscent of other three-tray sifting litter systems. Yet it’s a plus-sized model, which welcomes even the fattest cats.

When you buy something oversized, you expect a lot of internal room and flexible fitment. The model won’t fail you in that term, since the solid pans are huge enough to fit in four regular overweight adult cats over 13 lbs, or a couple of 18lb Maine Coons.

High rim

This So Phresh model is unique to other three-tray trees on this review list thanks to a detachable high rim feature.

If you want to take the unit on the go, assemble the rim upside down for a more compact package. On a daily basis, it can also act as a ford to guard against your sided peeing and kicking boy.


The sifting pan is sufficiently large to boost the litter filtering process in one go, for sure.

The holes, on the other hand, maybe bigger and allow a few pine pellets to slip through, leading to clogs, so you may want to second the idea of using pellet litter.

  • Spacious extra-large hollow to room multiple small cats or one big breed
  • Tight fitment
  • There isn’t enough headspace between the sifter pan and the solid pans
  • The litter-filled pan is heavy to lift

#8. Petmate Simple Sifting Litter Pan

Dimensions 19.4″ L x 15.6″ W x 7″ H
Color Blue/Gray
Compatible Litter Standard clumping litter

Buy it on Amazon

Rounded blade pattern at the bottom of the sifting pan

The pattern at the bottom of the strainer is one of a kind to every other sifting litter box we’re reviewing.

The holes are organized in long curved strips rather than identical tiny spheres as usual. This is a way to smoothen the rhythm of clean used granule flow and enable you to filter out clean versus soiled litter in one go.

Gently sloping profile

The edge of the pans ends up with an elegant curve. Each pan is 4-4.5 inches high, which gives a perk to senior arthritis cats and soft-boned kittens for their easy entrance.

Reinforced plastic bottom

Old but gold is the concrete description for a traditional uncovered plastic litter box. We all love eco-friendly disposable material, yet not everyone can afford that much of a sum for a new litter box monthly.

There’s still little to no established research confirming the harms plastic will cause to you and your cats besides the dire effects it exerts on the environment.

All in all, reinforced plastic is durable, heavy-duty, light-weight, and sleek to accelerate wiping movements. Thus, is still a classic cult in the most comprehensible senses.


The bottom of the sifting tray sticks to the bottom of the solid pan literally. So unless you can hot glue some strips of liners/foams on the solid pan about an inch high to separate the two, you’ll have to constantly lift and shake the grill to allow some extra space for the litter to mount.

Many people have also reported having difficulties with removing wet litter clumps stuck inside the rounded blades and compared this eccentric design with the more user-friendly Arm & Hammer version.

By conventional wisdom, a simple way to curb this mess is to fill the box with more litter, ideally at three-four inches in height, to raise the bedding level and keep the litter clumps floating on top.

  • Sturdy three-tray stacking design
  • Simple to use and clean
  • Do not trap foul odor that disturbs both you and your cats
  • Oversized holes (2″ L – 1″ W) allow pellets to penetrate through
  • The top tray is too narrow for a medium adult cat to fit in

#9. Van Ness Framed Sifting Litter Box

Van Ness Framed Sifting Litter Box

Dimensions 19″ L x 15.13″ W x 8″ H
Color Assorted
Compatible Litter Organic clumping litter, Breeze Pellets, Granular non-clumping litter, Granular flushable/compostable litter

Buy it on Amazon

Stain-resistant polished finish

The overall construction is built from highly polished food-grade plastic, which is non-toxic for the owners and shouldn’t raise the cats’ hormone level or react excessively with fecal stains.

The slippery structure also makes it easy for you to wipe off the dirt or rinse well under a high-pressure hose/pump with diluted soap liquid.

Detachable guard

Upon delivery, you’ll receive the whole unit including the guard, but seated into the top solid pan for better compactness along the go. This guard frame can be raised above the rim of the top pan by clipping a plastic tab at each long end.

The guard also adds a few fractions of inches more to the height of the grid, which offers you a grip to hold on when lifting and a fence against litter pieces kicked out by those active paws.

Low entrance

The entry point tops the chart off with 4 inches only, so even a cute dwarf Munchkin can still hop on hop off with almost no problem. The high rim built from the frame above can catch anxious cat parents a little bit off-guard, yet it covers two sides and the back only so the entrance won’t be elevated.

Tiny orifices

The size of the holes on the strainer is only ⅛ to 3/16” in general. It’s great to collect sawdust and granular litter types (best with clumping granules). The fecal waste/clumps would be too large to make it through the grid. This system works identically to the Breeze technology of Purina’s Tidy Cat but is more rugged and rudimental.


The model can be described as a knocked-off version of the Tidy Cat’s Breeze system (view this demonstration clip from VanNessPets). That also means you can’t maintain it without using some sort of accessories like puppy pads, litter box mats, or liners.

And this litter box’s working mechanisms can be somewhat old-fashioned. The idea was put into effect in 2011, 9 years ago so maybe you can consider nestling the strainer between two solid pans instead of following the user manual to prevent clogs more effectively and diversify the litter portfolio.

  • FDA-approved materials (*2008/282/EC, US Food and Drug Administration (FDA), 6/2010)
  • The sifting pan is large
  • The original method of use is confusing
  • Flimsy clips

#10. Omega Paw Elite Roll’n Clean Litter Box

Dimensions 16.5″ L x 18.5″ W x 17″ H
Color Midnight Black
Compatible Litter Non-stick clumping litter (such as Arm & Hammer Slide or Big Lots)

Buy it on Amazon

Eco-friendly barrel self-cleaning system

This litter box is doing differently like no other: You roll instead of lifting the grid to sift. It was absolutely born to offer the easy way out for delicate hands where lifting and bending down can be overwhelming.

The tilting system works similarly to the Catit SmartSift one with the way fecal/urinated clumps fall into a drawer/receptacle compartment, which aims for labor and time-saving features.

Covered design

The unit comes with a roof so if your cat is an introvert and prefers low-traffic areas when doing his/her thing, the hood would suit his taste.

Yet the performance wouldn’t be up to your expectation once the little prince/princess finds himself/herself confined inside a boxed enclosure.

Bonus litter step

Since non-tracking silica gel crystals don’t seem to cooperate well with a sifting system, and the most compatible litter type to get screened out is the clumping type, tracking is always the main criticism from anti-sifters.

To combat this setback, Omega Paw has special offers regarding litter steps to catch all the excessive granules sticking on those fluffy paws when their owners step out after relief time.


Even with a chrome snap-down locking clip, the internal contents are bound to leak once you roll the unit upside down. A feasible solution would be to glue a sponge/foam weather strip to the top of the litter tray concretely when you first purchase the product.

One further issue is that the litter granules will stick on the sides and even the receptacle compartment, which equals the loss of clean litter.

If you achieved zero results for a non-stick litter brand, then consider spraying the interior with Rustoleum neverwet treatment or cooking spray, and voila, as slippery as a fish.

On another note, since this design is comparable to the Catit SmartSift, it would be more of a blast if Omega Paw decided to come out with some kind of liners/pads to coat the drawer like its rival.

  • Offer plenty of internal room
  • The rolling system can separate waste clumps out of clean litter effortlessly without using manual labor
  • The flimsy seal between the top and bottom
  • The grate can pop out easily

FAQs & Tips

Who should buy sifting litter boxes?

When it comes to scooping traditional litter boxes, you’ve got a lot to take into consideration such as litter types, stool stuck at the bottom, sawdust crumbs in the vicinity, deodorizers, hose/sewage system, or garbage sorting.

Witnessing the hassle cat parents have to bear every day, sifting boxes were born with user-friendly features with respect to the amount of time spent, the mess created, and the litter used. In fact, the best models can cut the time down by half at optimum.

In reality, not everyone fancies sifting litter boxes. Naturally, they require quite an investment in budget and maintenance compared to the commonplace types of litter pans due to the detachable sieve. So if you value time reduction more than the cost, it’s safe to have a go.

Another triggered thing to note, kittens tend to put the expandable clumping litter in their mouth out of curiosity in the first three-four months of their life, which would then scratch their tiny intestines. Thus, unfortunately, you shouldn’t use sifting litter boxes for newborn babies.

What to look for in a sifting litter box of good quality?

What to look for in a sifting litter box

For the utmost honest experiences, there’s no other better way than laying your hand on different brands for each month. But that sounds out of this world, and no one could afford the time or money for these trials and errors.

That’s why it’s rather rational to draw out a list of critical features that you’re looking for to please both you and your furball in advance before determining which sifting litter box is the right one.


Everything should stay on track if you follow the same sizes of your current regular sand pans while choosing sifting boxes since your cats have been used to them already.

In case you’re fresh and clean, then reckon with getting a sandbox with the length exceeding the distance from your cat’s nose to the tip of its fully stretched tail, while the width goes beyond the same distance but with the folded tail. And out of consideration for his kicks, the height should waver around 5-7 inches at best.

If you house a clowder of cats, then try an extra-large litter box ample enough for them to share together. Or you can go for corner sifting litter boxes if you’re in an apartment or have been running out of space.

Overall Materials

The overall construction shouldn’t give in to wear and tear too fast if that’s not a must. In general, cat lovers prefer something sturdy but lightweight and labor-saving upon cleaning. Right now, reinforced plastic is all the rave.

Ease of Use & Maintenance

When you’re looking for something that can actually work out for both your babies and your own convenience, consider friendly features such as a 3-layer construction or elevated/hooded sides to combat spillages.

If you could find such a box already, then congratulations! Yet, this is the part where it gets tricky, the sieve.

First of all, it should be made from sturdy materials to hold up well under pressure water. Secondly, the size of its holes must neither be too narrow to make it compatible with a large range of litter types nor too wide to let litter clumps slip through.


Nothing wrong with bringing back a cute and vivid sifting litter box to your home! It would absolutely make a stylish decor to your furniture.

Choose whichever color suits your taste, since your cats can only see muted green and blue anyway. To them, motion is all that matters.

And take it as inspiration whenever you have to clean the sandbox up since you can now view those daily tedious rinsing tasks as a glowing-up routine to maintain something at least pretty.

Odor Constraint

Sometimes, it’s not about sizes, colors, reinforced plastic, or hooded edges that matter. Everything else would come second if you’re sensitive to smells. It’s such a splitting headache imagining that foul and putrid stool odor lingering onto your attires or your master room’s carpet.

To escape from this nightmare, a hooded sifting litter box that traps bad odors within that little space or uncovered units but is equipped with extra antimicrobial features would be a great help.

How do you clean pine pellet cat litter – Scooping vs Sifting?


The reason why pine pellets get a special feature on our review list is that compared to clay or silica litter, it offers many more benefits for you, your feline friends, and the environment.

In regards to health issues, both sodium bentonite and sodium silicate, the bases of clay clumping litter and silica gel crystals, are easily inhaled by cats while self-grooming and by humans as well. Some of the bits get expanded x15 times inside the body leading to asthma or gastrointestinal blockages, while the others are conducive to lung cancer, bronchitis, human tuberculosis, or cat’s silico-tuberculosis.

Also, if you take environmental aspects into consideration, a wood pellet is much more eco-friendly as clay-based litter is not biodegradable or compostable. To make the matter worse, people have to execute a process called strip mining which sheds all topsoil and vegetation carpet to extract clay-based litter.

And the final merits you get by using wood pellets, if not the merriest, is their amazing odor absorbability. Even urinated litter crumbs are claimed to disperse a lumber-like smell or a pretty pleasant scent to the nose of both the owners and the cats.

All in all, how do the magical wood pellets work? Notably, they break down into sawdust upon coming in contact with moisture. The waste pieces would eventually remain at the bottom, coated under the fresh pine pellets. Thus working out a way to separate the sawdust from the unused pellets is the main point here.

Below are two main approaches that people normally adapt, you can view a dual-way demo cleaning routine via this How to Clean Cat Litter Boxes Using Pine Pellets video by m3rma1d:


The critical item needed for this method is a scoop shovel. Compared to using sifting litter boxes, you’d be required to spend more time doing research on a scoop with properly sized slots, durable and lightweight material, an ergonomic grip handle, and is smartly curved to fit the sand pans. This, again, equals wasting time.

Not to mention, the microscope sawdust must definitely have been bickering with each other and scattering around midway from the litter box to the trash bin.


A litter box featuring a sifting tray has the same working principles as a scooping shovel, but on a larger scale for sure. It is built to help you sort out the sawdust and the fresh pellets at once without creating a mess or wasting time on repetitive scooping.

How do sifting litter boxes work?

Since wood pellets are our ultimate priority, sifting litter box manufacturers have dedicated a whole drawer construction specifically designated to them.

As demonstrated from the video above, the sieve on top of a sifting litter box allows sawdust to penetrate through its holes and retain unused pine pellets.

The drawer, laid beneath the sieve, would catch the sawdust. If you feel like freshening up is on a call, you just need to slide out the chassis and wrap the waste up in the pads/liners to discard into the bin, no room for lifting.

On the other hand, it’s not the drawer but the stacking tree system is a staple as clumping litter still sells like hotcakes. The two designs below are the most popular products on mainstream channels.

In a two-tray sifting litter tree room, one sieve/sifting tray fits snuggly inside a regular solid pan.

A three-tray sifting litter tree incorporates the same construction as its two-layer counterparts with another plain pan. It acts as an extra protection tray for you to place the sieve on while moving it from the litter box destination to the trash bin. In this way, the system can completely block all spillages.

Once you pick up the sifting tray and give it a firm shake, all the urinated clumps and feces would stay put over the sieve while the clean bentonite bits fall into the bottom pan.

How do you sift pine litter?

As mentioned above, it’s believed that wood pellets, the majority of which is pine, are the most eco-friendly and health beneficial. Along the road to find the best sifting litter box for pine pellets, you should at least shed light on how it operates on a usual basis first.

In theory, clumping litter is the most compatible with the sifting pan’s filtering holes. Largely, fresh pine pellets would slip through the holes along with the sawdust, since bentonite litter clumps are often bigger than the pellets, which in return eliminates all the purpose of using sifting litter boxes.

Since finding a sifting litter box for pine pellets is no easy quest among the regular lines, how about resorting to the models intended for the pellets merely?

You can get your hand on the drawers, and one starking example is the Breeze system developed by Purina. The holes are still too minuscule to allow any unused wood pellet to slide down alongside its sawdust.

What are the pros and cons of using sifting litter boxes?

Let’s go through some widely known claims.

Claim 1: Sifting litter boxes are easier to clean

In the first place, sifting litter boxes were built to facilitate ease of cleaning. This is indeed true if you use bentonite-based clumping litter since you wouldn’t have to turn to a slotted shovel and scoop up the stool first-handed.

Yet, in the event that you prefer pine pellets, the scooping procedures still have to be cleared like with traditional litter boxes. The workload can only be reduced at a later step when you place a cat pad/paper liner over the drawer.

Claim 2: Using sifting litter boxes can save more time

The only difference between a sifting and an old-school litter box is the scope of a sieve and a portable scoop. That’s why only when you shake the sieve can be considered a time depletion, in lieu of repetitive scooping activities. Otherwise, everything else remains the same old cleaning techniques.

Claim 3: Sifting litter boxes hold great control of dust

As far as everything else has been concerned, this may become the biggest demerit of sifting litter boxes. Remember the most suitable type of litter to go with a sifting pan is bentonite-based clumping litter, do you?

Even when clumping litter manufacturers label their products as 99.8% dust-free, there are still microscope granules flying here and there, especially considering you have to shake the sieve upon cleaning and refilling, and bentonite clumps are among the dustiest on the market.

On the greener side of the grass, this statement holds its weight better when it comes to wood pellet crumbs and sawdust, even though it’s partly because these are not as dusty as the bentonite granules by nature.

Claim 4: You can only use clumping litter for sifting litter boxes

This declaration is largely relevant if we don’t include sifting drawers for dissolvable wood pellets, since they’re viewed as a niche on the whole. The sifting tray would outperform if the litter can form big clumps to remain seated over the screen, so besides bentonite-based litter, grass or walnut shells are also excellent choices, if you ignore the price and your cat’s personal taste.

Overall, bentonite clumping litter ticks all the boxes. Non-clumping clay litter granules clear the screen well even if they’re wet and dirty since there’s no big clump for the sieve to retain. Silica gel crystals are too big and easy to scratch your cats, both in and outside. Also, wheat-based litter can form aflatoxins fungus, which causes cancer in your cats.

How do I clean a sifting litter box?

In case you’re having the drawer type, just peel the liners of the drawer. If your babies have done their number 2 too frequently, pick up a shovel and scoop the stool out.

In a different manner, if you own stacking sifting litter boxes that insist on using clumping litter, simply lift the sieve up to pour all the contents into the trash after sifting.

In general, it’s not necessary to scoop the stool away like with the drawer, but you still need to wipe the edges, and the hollow and poke the holes to sterilize all the components once in three-four weeks.

A piece of a caveat: Do not involve bleach or any heavy chemicals to disinfect your cat’s surroundings. It’s daunting to learn that bleach can react to stale urine to form chlorine gas which is full of toxins and can cause explosions.

Rather, you can dilute soap liquid into warm water to rinse the whole thing and use non-scented/light-scented non-granular deodorizers to safely eliminate the foul smells without causing respiratory irritation and infections to your furballs.
