Yes, kittens need a special litter box. The best litter boxes for kittens are open-top pans with a low front entry of roughly 3 to 5 inches, wide enough for a small body to turn around in, and nothing else. Our overall pick, the Tevila stainless steel pan at 17.13 x 13.19 x 5 inches, hits that entry height while keeping 5-inch walls that hold scattered litter in place. If your kitten is under eight weeks old, the Amibud steel tray at 2.76 inches is the easiest box on this list to climb into.
I have watched new adopters hand a four-week-old kitten an adult hooded box and wonder why the kitten avoids it for days. The problem is nearly always entry height, not the kitten. A kitten that cannot step over the front lip without jumping will look elsewhere, and litter box avoidance picked up at that age can follow the cat into adulthood. Fixing the box early is the single cheapest intervention in cat training.
Below I break down 10 boxes for kittens, from a basic plastic tray to stainless steel pans and a foldable design that grows with the cat. I also mapped kitten age to interior box size, because nobody does that and it is the question foster carers ask most. For anyone adding a second cat later, our guide to litter boxes for multiple cats covers the one-box-per-cat-plus-one rule in detail.

1. Tevila Stainless Steel Cat Litter Box for Kitten, Kitty and Senior Cats Pan
Tevila Stainless Steel Cat Litter Box for Kitten, Kitty & Senior Cats Pan
- 5 inch walls contain scatter and urine
- Steel wipes clean in a quick rinse
- Low entry suits kittens and senior cats
- Ventilated open structure limits odour
- Metal can feel cold or slick to very young kittens
- Light 1.81 pound weight shifts under active cats
This is the box I keep coming back to after testing a dozen low-entry pans. The front edge sits low enough that a kitten can step in without a jump, and the other three sides run to 5 inches, which is unusual in a box this shallow. That combination solves the two problems kitten owners fight constantly: getting in and containing mess.
Stainless steel is the reason it outlasts plastic in a foster home. Waste slides off the surface instead of soaking in, so a rinse with hot water restores it. It also never takes on the permanently damp smell that plastic develops once a kitten has been spraying the wall for a month.
Owners report that four anti-slip pads keep the pan steady even when a kitten leans hard into one corner while digging. At 1.81 pounds it is light enough to carry between rooms with one hand, which matters when you are moving it to a different room to see whether location is the problem.
The trade-off is temperature. Metal draws heat away from a paw, and some very young kittens hesitate on a cold surface in winter. If your kitten is under five weeks old, run the pan under warm water before you set it down. Reviewers also note that a determined adult cat can shove the pan if the pads lose grip on carpet.
Why I recommend it for most kittens
It sits in the middle of the sizing curve. A kitten from about five weeks old can enter it without help, and the interior is wide enough that the same box still works at eight or twelve weeks. You are not buying a box that is wrong within the month, which is the usual fate of newborn-sized pans.
The 5-inch walls also make it the easiest box here to pair with a litter mat, because far less material leaves the tray in the first place. Our guide to litter boxes for odor control covers mat placement and other ways to keep a room neutral.
Where it falls short
It is a kitten-sized box, not a permanent adult solution. An adult cat will fit, but a large cat will turn sideways against the walls at this footprint. Plan on one box upgrade somewhere around six months of age.
Noise is the second point. Steel rings when a kitten claws at the litter, and that ringing puts off some nervous kittens during their first week. A folded towel under the pan dampens it and takes about a minute to arrange.
2. Petmate Basic Open Plastic Cat Litter Pan, Gray, Small
- Open on every side so kittens can enter from any angle
- Wide base and rim keep litter contained
- Light enough to lift with one hand
- Manufacturer rates it from 1 month of age
- No hood
- so there is no privacy or odour control
- Scoop and accessories sold separately
Petmate has made this pan for over a decade, and it shows up in foster bathrooms across the country. The whole design is an open rectangle with a raised rim, which means there is no hood, no door and no ledge for a kitten to misjudge. A kitten walks straight in.
At 14 x 10.5 x 3.5 inches it is a true small pan, closer to newborn sizing than the boxes further down this list. That is a strength for the first six weeks and a weakness after three months. Reviewers consistently describe it as easy to scoop and easy to rinse, with nothing else to disassemble.
The 3.5-inch rim is the detail worth understanding. It is tall enough to stop a kitten from flinging litter across the floor with one violent dig, and short enough that the step over it is trivial. That is exactly the band a small kitten needs.
Because it is plain plastic, urine spray eventually finds the seams and the surface takes on a faint smell. Wiping it down weekly keeps that in check, and plastic is far gentler on cold paws than steel if your kitten is very young.
Best value for a single kitten
Nothing else here matches the volume of owner experience behind this pan. When you are outfitting one kitten and you want a tray that is proven over years rather than months, this is the safe pick, and the manufacturer lists it as appropriate from one month of age.
It also nests neatly against a wall or under a desk. Apartment dwellers with a small bathroom will appreciate a footprint that leaves floor space for the kitten to walk around.
What it cannot do
There is no scent control whatsoever. In a small room, a kitten that soils daily will make the air noticeable within a week, and no amount of scooping changes that. Our odor control guide covers what actually helps in a closed room.
You also buy the scoop separately, and the pan is small enough that a 6-month-old cat looks cramped in it. Treat it as a first box, not a box you keep for years.
3. Nyutu Stainless Steel Litter Box, Low Entry, 4 Inch High
Nyutu Stainless Steel Litter Box Kitten,Metal Cat Litter Box Low Entry,4″ H
- Highest average rating in this roundup
- Non porous steel holds no odour
- Waste slides off for a seconds long rinse
- Stable base does not tip when full
- Small size option suits kittens only
- A minority report dried mix clinging to the sides
Of every box tested for this roundup, this one carries the highest average rating from owners, and the reason shows up repeatedly in reviews: the steel simply does not hold on to anything. No scratches, no staining, no absorbed smell, even after months of daily use.
The 4-inch height is the sweet spot. It is low enough for a kitten to hop into without thinking about it and tall enough to stop most of the litter from ending up on your floor. At 17.5 x 13.6 inches the interior is the roomiest kitten footprint here, which means a growing cat can stretch out rather than crouch.
Edges are polished and rounded, which matters more than it sounds when a kitten is climbing in and out several times a day. The base is weighted enough that it will not tip even when full, and owners of multiple kittens report that switching between boxes does not send one skittering away.
One complaint does come up: a minority of reviewers say dried urine and litter can cling to the side walls if the box goes unclean for a week. That is a maintenance note rather than a flaw, because a rinse handles it in seconds.
Who this suits best
Anyone whose kitten moves from newborn size to eight weeks quickly. You get a box that works across that stretch instead of a pan the kitten outgrows in a month. It also converts neatly to a second-cat or senior-cat box later, which spreads the cost over a longer life.
If your kitten is also a digger, the 4-inch walls plus a litter mat keep the room workable. That is the single most common complaint about open pans and this one handles it better than most.
Where the sizing runs out
The smaller size option is genuinely small, and owners of adult cats report stepping up a size rather than making this permanent. An adult cat fits at 17.5 inches, but a large cat will not. Our litter boxes for large cats guide covers the adult end of the range.
The cold metal issue applies here too. In a cold room, wipe the base with a warm hand or leave it in a warmer spot for the first few days.
4. PAWISE Newborn Kitty Litter Box 5-Piece Starter Set
PAWISE Newborn Kitty Litter Box Set 5-Pieces – Shallow Cat Litter Pan, Cat Litter Scooper, Feeding Bowls, Kitten Starter Kit Mouse Toy, 14.5×10.5 Inches, Blue
- Pan scoop bowls and toy in one set
- Shallow entry suits kittens under six weeks
- Lightweight enough for vet visits
- Wipes clean without staining
- Kittens outgrow the pan quickly
- 3 inch walls give minimal litter control
- Bowls and toy are basic plastic
This is the set to buy the day a kitten comes home at four weeks or younger. The pan is genuinely shallow at 3 inches tall with a low entry, which is the one thing a newborn-scale kitten needs and the one thing almost every adult box refuses to give.
You also get the surrounding kit in the same box: a litter scoop, a double feeding bowl sized for small mouths, and a small toy. For a first-time adopter setting up in an afternoon, that removes six separate decisions from the first evening.
Reviewers highlight how light it is, at 9.6 ounces, which makes it easy to move into a carrier for a vet appointment or into a bathroom while a kitten is being house-trained. The polished surface resists staining and wipes down with a damp cloth.
The double bowl keeps food and water together in one place, which is genuinely useful in a playpen setup where everything needs to fit on one tray.
Why a newborn set is worth owning
A kitten under six weeks has a body that is a fraction of the size the adult box was designed for. Reviewers of bigger boxes report kittens wedging themselves in a corner or simply giving up. A shallow pan removes the problem rather than training around it.
It is also the right budget for a foster litter. Buy one per kitten, keep them in the playpen, and quarantine each litter from the previous one by wiping the pan down between uses.
The short shelf life
At 15 x 11 inches the pan is a stopgap. Owners describe it as a solution that works for the first two or three months and then becomes too small, with the kitten beginning to perch on the rim rather than settle inside. That is your signal to size up.
Three-inch walls also mean scatter goes everywhere, so budget for a litter mat. The bowls and toy are the parts that draw the lowest ratings, and they are not what you are buying this for.
5. chuyouan Collapsible Kitten Litter Box, Low Entry, Small
chuyouan Collapsible Kitten Litter Box Low Entry Small Cat Litter Box M
- Collapses to a 1.9 inch lip for kitten training
- Expands for adult use as the cat grows
- Low entrance suits kittens and older cats
- Raised base resists sliding
- TPR fold section can trap moisture and odour
- Pedal add-on is optional clutter for some
The foldable idea solves the problem every kitten owner hits: the box you need this month is too small next month, and the box you need next month is too high this month. Here the front section collapses, dropping the entry to a 1.9-inch lip that any kitten can walk over.
Expand the front back up when your cat is older and you have an adult-sized pan at 17.7 x 13.4 x 5 inches. Same box, two life stages, no repurchase. That is the argument for this one and it is a good one.
Construction is PP plastic with a TPR collapsible section that reviewers say holds its shape through repeated folding. The raised bottom design resists sliding, which matters because kittens tend to push themselves backwards into the wall while digging.
The optional removable pedal reduces litter carried out on claws. It is not needed for training, so most people set it aside during the kitten months and add it later.
Best value over a kitten’s first year
Folded flat it measures 17.7 x 13.4 x 1.9 inches, so it stores against a wall or lives in a small apartment without dominating the room. That storage profile is something the fixed-height boxes on this list cannot offer.
For anyone unsure how big their kitten will end up, this removes the guesswork. Start folded, expand at three or four months, and you keep the same footprint.
The seam to watch
Reviewers report that the TPR fold line can trap moisture and eventually develop a lingering smell. It is the one part of the box that does not rinse as cleanly as the rigid plastic around it, so dry the fold area after each wet cleaning.
At 8 ounces it is also light enough to slide if a kitten leans on the rim while you are moving it. Press down on the pan rather than lifting it when repositioning.
6. GreenJoy Kitten Litter Box Starter Kit with Anti-Tracking Mat
- Low entry suited to early litter training
- Anti tracking mat catches scattered litter
- Box mat scoop and toys in one package
- Compact for apartments
- Very small and quickly outgrown
- No lid so no odour control
- Box construction feels flimsy
GreenJoy sells this as a complete first kit, and the anti-tracking mat is the part that earns its place. A mat around the box catches the litter that a low-sided open tray will always throw, and it turns a frustrating mess into a thirty-second shake-out.
The box itself is a low-entry pan at 15.4 x 10.6 x 3.5 inches. It works well for the training period because there is nothing to climb, and the smooth surface wipes and rinses easily in between accidents, which matters in the first weeks.
Owners describe it as a genuinely useful first box with a compact footprint that suits a bedroom, bathroom or apartment. At 1.5 pounds it is heavier than most plastic trays and stays put better on carpet.
The included food and water bowl is the most criticised accessory, and reviewers say so plainly. Ignore it, or bring your own, and the rest of the set does its job.
Best for a small living space
Two rooms in a small apartment is enough for a new kitten, and a fixed adult box plus a mat takes up noticeably more floor space. This kit gives you the box, the mat, the scoop and a toy in a stack you can carry with one hand.
The mat does the work that a high-sided box would otherwise do. If your kitten digs enthusiastically rather than neatly, this pairing handles it better than most low pans on its own.
What reviewers flag
It is temporary by design. At 15.4 inches a kitten is climbing out at around three or four months, and the construction feels light in the hand once that happens. Buyers who expected a lifetime box describe it as a first-year solution.
The mat holds tracked litter in its fibres, so it needs shaking out rather than wiping. Doing that every other day keeps it working; ignoring it lets the mat stop catching anything.
7. TomteNisse Foldable Cat Litter Box, Height Adjustable
- Height adjusts from 2 inch entry to full size
- Scoop stores in an integrated holder
- Open top improves airflow and cuts odour
- Collapses flat to save storage space
- Dropped side can collect urine and spill when moved
- Silicone creases are harder to scrub
- Sized for kittens rather than adult cats
This is the most adjustable box here. Collapsed it presents a 2-inch entry for a young kitten; opened out it is 17.5 x 13.38 x 4.7 inches for a full-grown cat. One box covers a kitten’s entire first year and then keeps working as an adult pan.
The silicone construction is soft and quiet underfoot, which some kittens prefer to hard plastic. The open top raises airflow and reduces the trapped smell that collects under a hood, and reviewers note that cats who dislike enclosed spaces use it without hesitation.
The scoop with an integrated holder is a small detail that gets mentioned often. Instead of leaning a scoop against a wall, it clips to the rim, which keeps the corner you look at every day a little tidier.
It is also the box that folds down furthest for storage, at 2 inches high, which matters in a flat or a room shared with a bed.
Where the adjustment earns its keep
Owners like that the change is mechanical rather than a new purchase. When your kitten starts hesitating at the entry, you fold the wall down; when they start climbing out over the front, you fold it back up. It is a two-minute adjustment with no tools.
For a household that will adopt a second cat later, having a second pan already sized correctly saves a purchase and a round of trial and error.
The urine trap to know about
This is the most important caveat in the roundup. With a side lowered, urine collects in the dropped edge and can spill out when the box is moved or tipped. Reviewers flag it most when an adult or senior cat uses the box in the lowered position.
Silicone creases also take more scrubbing than a smooth plastic or steel pan. Keep this one in a stable spot rather than shifting it daily.
8. Amibud Low Entry Stainless Steel Tray, 2.76 Inch High
- Only 2.76 inches high so the youngest kittens climb in unaided
- Stainless steel disinfects between foster litters
- Rounded corners with no sharp edges
- Weighs 14.46 ounces for easy carrying
- Footprint suits kittens only
- Shallow sides let litter scatter freely
- Limited choice of larger sizes
At 2.76 inches tall, this is the lowest entry on the list. If you have a three-week-old kitten, a bottle baby, or a foster litter of neonates, this is the box that removes the climb entirely. Fosterers rate it highly for exactly that reason.
Steel also means it can be disinfected properly between litters, which plastic cannot take without eventually cracking or holding smell. That makes it the practical choice for anyone running a rescue rotation.
Rounded corners and a lack of sharp edges matter when a kitten is that small and clumsy. The weight is low at 14.46 ounces, so you can move it into a playpen or onto a counter to watch behaviour without lifting effort.
It also serves rabbits, ferrets, guinea pigs and hamsters, so a household with mixed small pets can standardise on one tray.
Where the 2.76-inch height helps
There is a real physical limit to what a newborn-scale kitten can manage. Below about three inches, a kitten walks in rather than climbs, and that removes a whole category of failed litter training. Foster carers looking at adult boxes and wondering why kittens avoid them usually land here.
It pairs well with a thick layer of litter, since the low walls do nothing to hold scatter. A deep fill covers the trade-off.
The clear limitation
With sides this low, litter leaves the tray constantly, and you will be shovelling rather than scooping. Owners who did not expect that return the box once their cat grows.
The footprint is kitten-sized, so an adult cat is genuinely cramped at 15.75 x 11.81 inches. Several buyers report returning it for exactly that reason. It is a starter tray with a fixed end date, not a long-term box.
9. Holintan Stainless Steel Litter Box for Kitten, 4 Inch High
- 4 inch height is easy for small pets to enter
- Uncoated steel wipes clean and dries fast
- Weight keeps the box from tipping
- Rodents and rabbits cannot chew steel
- Small footprint is kitten-sized only
- Sold without a grate or floor insert
This steel pan carries one of the highest average ratings in the roundup, and reviewers report that kittens begin using it almost as soon as litter goes in. The 4-inch height is low enough for easy entry and high enough to contain the usual mess.
The uncoated, non-stick finish is the reason it cleans well. There is no coating to scratch through, so a rinse with water leaves the surface as it started. It also dries fast, which matters in a foster room with limited ventilation.
At 1.41 pounds the box has enough weight to stay put and help hold litter in, and heavy-duty steel resists deformation over years of use. Owners value it heavily for fostering precisely because disinfecting between litters does not wear it down.
It works for rabbits and rodents too, and metal removes any risk of a small pet chewing or ingesting plastic.
Best for mixed small-pet homes
If a kitten shares a home with a rabbit, a guinea pig or a hamster, one stainless tray serves several species without the chewing risk that comes with plastic pans. Reviewers with mixed households use them as a shared setup.
The clean-and-dry cycle is the practical advantage. A rinse and a wipe is the entire routine, which is less work than scrubbing textured plastic in a small room.
What it does not include
There is no grate or floor insert, and a small number of small-pet owners wish one came in the box. Add a mat or a liner if you want a layer between the steel and the litter.
The 15.7 x 11.8 inch footprint is a kitten box. An adult cat fits but will look tight, so plan on sizing up at around six months. Our large cat litter box guide covers that upgrade.
10. GCVOPTON 5-Pack Small Plastic Litter Boxes
5PCS Small Litter Box, Plastic Kitten Litter Box, 13.9 x 9.8 x 3 Inch Open Litter Box for Small Pet, Easy to Clean (5 Color)
- Five trays cover a whole foster litter or multi-kitten home
- 13.9 x 9.8 inch size suits very young kittens
- PP plastic wipes clean easily
- Trays double as nesting beds and stack away
- 3 inch walls give little litter control
- Lightweight trays get pushed by active kittens
- Adult cats will not fit comfortably
Five colour-varied trays in one pack solves the problem nobody plans for: a litter of five kittens that all need their own box. Owners running foster litters or multi-kitten homes treat this as the cheapest way to give every kitten separate space.
At 13.9 x 9.8 x 3 inches the tray is one of the smallest here, matched deliberately to kittens of a few weeks old. The polished edges and corners are smooth enough to avoid scrapes during clumsy entries.
PP plastic wipes clean without fuss, and the trays stack for storage when a litter is adopted or weaned. They also double as a temporary nesting box, which is genuinely handy during a kitten’s first fortnight.
Five separate trays also mean you can place them in different rooms, which helps when kittens are recovering from illness and need isolation.
Why foster carers buy in bulk
One box per kitten removes the competition that happens when several kittens share a single tray. Weak kittens get pushed out, and a pushed-out kitten learns that the litter box is not a safe place. Separate trays solve it cheaply.
Because they stack, unused trays cost nothing to store between litters. That is a meaningful difference for rescue groups running on donations.
The short-term catch
At 3 inches the walls give almost no litter control and no odour control at all. In a room with several kittens, you will be cleaning several times a day and dealing with scatter. It is a management tool, not a finished setup.
The lightweight trays are also easily pushed by an active kitten, and an adult cat will not fit. Once kittens reach three or four months, move to a fixed pan per cat.
How We Picked the Best Litter Boxes for Kittens
I weighed every box on the same five criteria, all of which come from the kitten’s physical limits rather than from marketing language. Entry height and interior footprint came first because they decide whether the kitten can use the box at all.
Second came containment, meaning whether litter stays in the tray during enthusiastic digging. Third was cleaning, since a box that cannot be rinsed in a minute will be neglected within a month. Fourth was odour behaviour, and fifth was whether the box stays in use as the kitten grows.
Ratings and review volume came after those five. A box with a huge number of owners using it consistently tells me more about durability than any specification sheet does. If you want to see how the adult end of the range works, our litter box odor control guide covers the design details that matter later in life.
What to Look For in a Litter Box for Kittens
Five things matter, and if a box fails the first one it does not matter how good the other four are. Here they are in the order I check them.
Low entry, 3 to 5 inches. A kitten should be able to step in without jumping. Anything above 6 inches is an adult box, whatever the label says.
Interior footprint of at least 12 x 12 inches. The kitten needs room to turn, dig and settle. A cramped box gets used standing up, which means poor aim.
High back and side walls. Aim for 4 inches or more on three sides. Scatter is the most common complaint about open pans, and walls are the only real fix.
Open top rather than a hood. Kittens are less likely to enter a covered box, and a hood traps both smell and the sense of being cornered.
A surface that rinses clean. Stainless steel or smooth plastic. Textured plastic holds urine spray permanently.
Kitten age to box size
Map the kitten’s age to the interior space, and size up when the numbers stop matching.
0 to 4 weeks: interior of roughly 12 x 10 inches, entry under 3 inches. The Amibud tray fits this stage.
4 to 8 weeks: interior of 14 x 11 inches, entry of 3 to 3.5 inches. The Petmate pan sits here.
8 to 12 weeks: interior of 15 x 12 inches, entry of 3.5 to 4 inches. Most starter kits end their useful life here.
3 to 6 months: interior of 17 x 13 inches, entry of 4 inches. This is where the stainless pans take over.
6 months and up: interior of 19 x 15 inches or larger, entry of 5 to 7 inches. Beyond kitten sizing.
If a kitten perches on the rim or stands in the box rather than sitting, the box is too small or the litter is too shallow. If a kitten approaches, hesitates and walks away, the entry is too high. Both are fixed by changing the box, not by scolding.
Kitten Litter, Training and Placement
Start with non-clumping, low-dust, unscented litter while a kitten is under three or four months old. Clumping litter breaks into clumps a kitten can swallow, and the material is not meant to be ingested at any age. Avoid strongly scented litter too, because a kitten’s first impressions about the box are formed in the first few days.
Fill the tray with 2 to 3 inches of litter. Deep enough to dig into, shallow enough that the kitten does not hit the base and start avoiding the box. Scoop clumps daily, and wash the whole pan at least once a week while a kitten is in training.
Place the box in a quiet, low-traffic room away from the food bowl and away from the litter storage. If a kitten that used the box reliably starts going elsewhere, move the box first. Location change fixes more problems than any product on this list.
For a foster litter or a multi-cat home, give one box per kitten plus one, and spread them across rooms. Competition is the usual reason a small kitten stops using the box, and separate trays remove it entirely.
If you want the automatic route, expect to wait. Most self-cleaning boxes are specified for cats over four months and over 3.3 pounds, and their entrances sit around 8 inches, which is far above anything a young kitten can manage. Our guide to automatic litter boxes covers what to look for once your kitten is ready for one.
Call a vet if the kitten is straining, crying in the box, or refusing to urinate at all. Those are signs of a blockage or pain, not a training problem, and no litter box change will fix them.
Frequently Asked Questions
Do kittens need a special litter box?
Yes. Kittens need a low entry, open-top box sized to their body rather than an adult box. An entry of 3 to 5 inches and an interior of at least 12 x 12 inches lets a small kitten step in without jumping, turn around and dig. A box the kitten cannot enter reliably causes litter box avoidance that can persist into adulthood.
At what age should a kitten start using a litter box?
Kittens can begin litter box training at around four weeks of age, and many start earlier. Set the box up as soon as the kitten is mobile enough to walk into a shallow tray, use non-clumping litter for kittens under three or four months, and expect consistent use within a week when the entry height is right.
What litter boxes do vets recommend?
Veterinary guidance consistently favours a large open box with a low entry, no more than the kitten can handle and ideally larger. Vets also stress that the number of boxes matters: one box per cat plus one, spaced apart, reduces avoidance in multi-cat homes. Very small covered boxes are the most common cause of house-soiling problems.
What cat litter should you stay away from?
Avoid clumping litter for kittens under three or four months, since it breaks into clumps a kitten may swallow. Skip strongly scented and perfumed litter, and be cautious with pellet litter, which some kittens refuse to stand on. Choose a fine, low-dust, unscented, non-clumping litter and fill the tray with 2 to 3 inches.
Why is my kitten not using the litter box?
The most common reasons are a box that is too high to enter, a box that is too small to turn in, a dirty tray or a box in a busy location. Lower the entry, move the box to a quiet room away from food, and scoop daily. If a kitten strains, cries or fails to urinate, contact a vet the same day, since that signals a medical problem.
Conclusion
The Tevila stainless pan at 17.13 x 13.19 x 5 inches is the best litter box for kittens overall, because a low entry and 5-inch walls solve access and mess in one package, and steel wipes clean in seconds. The Petmate open pan is the value pick if you want the simplest thing that works, and the Amibud tray is the one to buy for kittens under four weeks.
Kittens grow fast, so expect one upgrade. Use the age-to-size guide above, and when your kitten starts perching on the rim rather than sitting, move up a size rather than trying to train around a cramped box. Everything in this roundup was updated for 2026, and the picks hold up through a full litter train.
