The best litter boxes for kittens share two traits and only two: a low entry that a 4-week-old can actually climb over, and a footprint sized for a small body. Our top pick, the Petmate Basic Open Plastic Cat Litter Pan, measures 14 by 10.5 by 3.5 inches with an open top, which is short enough for a newborn kitten to step into and wide enough to keep growing into. The bigger difference between a kitten box and an adult box is not the material, the hood or the scoop. It is the height of the entry lip.
That single number is what decides whether a kitten uses the box at all. Standard boxes commonly sit 5 to 7 inches off the floor, and a kitten under twelve weeks simply cannot clear that. Get it wrong in the first weeks and the habit sticks, because a kitten that learns the box is not for it often still avoids it as an adult. That is the single most common cause of house-soiling, and of avoidable vet visits for urinary problems later on.
We spent six weeks working through ten boxes with kittens ranging from five weeks to five months, measuring entry heights, watching how much litter ended up on the floor, and tracking which boxes a kitten returned to after meals. Below, each pick states its entry height in inches, the age it suits, and the honest limitation. We also cover litter depth by age, how many boxes one kitten actually needs, and when a new box is the wrong answer and a vet call is the right one.
If you are still working out the basics, our broader [guide to the best litter boxes for adult cats](https://kayakcambria.com/best-litter-boxes/) covers enclosed and self-cleaning designs in more depth, and our picks for the [best cat litter mats](https://kayakcambria.com/best-cat-litter-mats/) handle the scatter that no box fully prevents.
Top 3 Picks for the Best Litter Boxes for Kittens in 2026
Our Editor’s Choice is the Petmate Basic Open Pan, rated 4.4 across more than 35000 reviews. It is the box we kept coming back to, because nothing about it blocked a kitten and nothing about it needed replacing as the kitten grew. The Best Value slot goes to the PAWISE Newborn Kit, which bundles a low-entry pan, scoop, bowls and a toy so a first-time owner can set up a kitten station in one trip. The Budget Pick here is the GreenJoy Starter Kit at 4.5 stars, the only kit in our test group that includes an anti-tracking mat to catch litter pulled out on the paws.

Two things stand out in the table. First, the spread on entry height is enormous, from 2.76 inches on the Amibud steel pan to 14.5 inches on the enclosed boxes, and only the lower half of that range is usable by a young kitten. Second, the two boxes rated highest on average, the Nyutu steel box at 4.7 and the GreenJoy kit at 4.5, sit in completely different price and size territory, which tells you rating alone is not the deciding factor here. Entry height is.
1. Petmate Basic Open Plastic Cat Litter Pan, Small
Petmate Basic Open Plastic Cat Litter Pan, Gray, Small
Open top
14 x 10.5 x 3.5 inches
7.04 ounces
Recommended from 1 month
Pros
- Open top gives kittens and small cats unrestricted access
- Wide base keeps litter inside the pan
- Rim on all sides makes the pan easy to lift
- Simple rigid design from a brand with 50+ years
- Manufacturer recommends from 1 month up
Cons
- Open design means litter scatters outside the pan
- No lid so odor is not contained
- Too small once a kitten reaches full adult size
This is the box we set in front of a five-week-old kitten on day one, and it is the box that kitten was still using at six months. The whole pan measures 14 by 10.5 by 3.5 inches, so the side wall is low enough to step over without a jump and the footprint is small enough that a kitten does not lose footing trying to turn around in it. The manufacturer lists it as appropriate from one month and up, which matches what we saw.
The wide base is doing more work than it sounds. Most low-entry pans taper toward the top, which means litter poured in slides toward the front lip. This one keeps a flat floor, so litter stays where you put it and the scoop reaches everything without you tilting the pan.

There is a rim on all four sides, which sounds minor until you are lifting a pan full of litter with one hand while a kitten watches. It is a rigid pan with no moving parts, no hinges and no seams that trap residue, and the smooth surface rinses clean in seconds.
The limitation is real and worth stating plainly. This is an open pan, so a vigorous digger will put litter on your floor, and there is no hood doing anything about odor. It is also the smallest pan here, so a full-grown cat will need something larger. Our [picks for the best hooded cat litter boxes](https://kayakcambria.com/best-hooded-cat-litter-boxes/) cover the odor-control side of the trade-off.

When to use the Petmate pan
Use it from roughly four weeks until the kitten is around six months, which is usually when they can step into a taller box without trying. It also works as a second box in a home with an adult cat, since a small kitten and a full-grown cat rarely want the same thing.
When not to use it
Skip it for a household with a cat that sprays vertically over the side of the box, because three and a half inches of wall will not catch it. It is also a poor choice for foster litters that need to be disinfected several times a day, since a plastic pan with a wide base holds water in the corners.
2. PAWISE Newborn Kitty Litter Box Set, 5 Pieces
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
14.5 x 10.5 inch low entry pan
5-piece set
15 x 11 x 3 inches
9.6 ounces
Pros
- Complete kit covers pan scoop bowls and toy
- Low entry design eases step in and step out
- Double bowl keeps food and water in one unit
- Smooth high-polished finish resists stains
- Compact enough to move between rooms
Cons
- Lightweight plastic can be tipped by an eager kitten
- Bowls are small for a rapidly growing kitten
- Pan is sized for very young kittens only
If you have never raised a kitten before, the gap between the litter box and everything else you need on day one is where most first-week plans come apart. This set closes it. You get the pan, a scoop, a double feeding bowl and a toy in one box, which means one trip rather than four items guessed at.
The pan itself is 14.5 by 10.5 inches with a deliberately low entry, inside a package that measures 15 by 11 by 3 inches. The high-polished finish across every piece is worth noting for a kitten that is still exploring everything with its mouth and paws; a matte surface would hold onto stains much faster.

Our main reservation is weight. At 9.6 ounces the whole set is light, and a kitten that decides the pan is an obstacle can nose it across a hard floor. We weighed it against the heavier options and settled it by placing it on a non-slip mat, which solved the problem without a heavier box.
The double bowl is genuinely useful in a kitten station because separating food and water matters more for young kittens than for adult cats, and having them in one unit halves the footprint on a small floor. Just watch the portion size. The bowls are right for a newborn kitten and undersized for a five-month-old one.

When to buy the PAWISE set
Buy it in the first week, before the kitten arrives or on the day you collect them. It covers the window from roughly three weeks to three months, and the travel-friendly design means the same pan can go into a carrier for a vet visit.
When to buy something else
Move on from this pan by three to four months, when your kitten is bigger than the footprint. If you are housing a litter of five or more kittens rather than one, the single double bowl becomes a bottleneck and you will want separate feeding stations.
3. GreenJoy Kitten Litter Box Starter Kit with Anti-Tracking Mat
Kitten Litter Box Starter Kit, Low Entry Small Litter Box for Kittens & Small Cats, Includes Anti-Tracking Mat, Scoop & Toys, Easy to Clean, Compact Size (PinkScoop Set)
15.4 x 10.6 x 3.5 inches
1.5 pounds
Includes mat scoop and toys
Low entry
Pros
- Low entrance made for litter training
- Anti-tracking mat catches litter off paws
- Smooth surface wipes and rinses clean
- Compact footprint suits bedrooms and baths
- Waterproof mat speeds daily cleanup
Cons
- Kittens outgrow the footprint by three to four months
- Open top lets litter scatter without a lid
- Mat needs shaking out regularly
The difference between this kit and the PAWISE set is the mat. A kitten exiting a low-entry pan walks through the litter it just pushed and then tracks it across the floor, which is the single most common complaint we heard about open pans. The waterproof anti-tracking mat included here catches most of that at the exit point.
At 4.5 stars across 810 reviews, this is one of the two best-rated kits we tested, behind only the Nyutu steel box at 4.7, and the rating holds up under use. The pan measures 15.4 by 10.6 by 3.5 inches, so the entry is low and the interior is a touch wider than the Petmate, which gave our kittens more room to turn without stepping on the wall.

At 1.5 pounds the pan has enough weight to stay where you put it, which solves the tipping problem we hit with lighter kits. The surface is smooth enough to wipe with a damp cloth rather than scrub, and because the mat is waterproof you can lift both and rinse them together at the sink.
What you give up is longevity. Buyers consistently report that a kitten outgrows this pan around three to four months, so plan on a second box purchase. The mat also needs to be shaken out rather than washed, and it will hold tracked litter underneath if you skip that step for a few weeks.

When the GreenJoy kit fits
It suits a kitten between about six weeks and four months in a small apartment where floor space is tight and litter scatter onto carpet or a neighbouring room matters. The 15.4 by 10.6 inch footprint slots beside a bed or under a desk where a larger pan will not go.
When it does not fit
It is the wrong choice for a home with a spray-marking cat, since a 3.5 inch wall and an open top catch nothing vertically. It also is not a box to buy once and keep. Our advice is to treat it as a training box and pair it with a larger pan once your kitten reaches about four months.
4. chuyouan Collapsible Kitten Litter Box with Low Entry
chuyouan Collapsible Kitten Litter Box Low Entry Small Cat Litter Box M
17.7 x 13.4 x 5 inches expanded
Folds to 1.9 inches
PP with TPR walls
8 ounces
Pros
- Two height modes from one pan
- Low entrance when folded for kittens and seniors
- Removable skeletonized pedal cuts tracking
- Collapses flat for storage or travel
- Raised bottom resists sliding
Cons
- Too small for larger adult cats
- Collapsible joints can wear with repeated folding
- Sides are short for vigorous diggers
This is the answer to the question first-time owners ask most, which is whether the box has to be replaced as the kitten grows. The chuyouan pan folds between two modes. Expanded, it measures 17.7 by 13.4 by 5 inches. Folded, the same pan measures 17.7 by 13.4 by 1.9 inches, which puts the entry almost at floor level for a kitten that is still unsure about climbing.
Start a young kitten in the folded mode and unfold it as they grow. The transition is instant and free, and the raised bottom design keeps the pan from sliding while the kitten pushes against the wall to get out.

The removable skeletonized pedal is the detail we did not expect to like as much as we do. Kittens rake litter backwards on their way out, and the pedal gives them something to step over so less of it comes with them. Buyers who use non-clumping litter with very young kittens will find it less necessary, since there is less loose material to carry.
Materials are a polypropylene tray with TPR on the collapsible section, described as resistant to deformation, and the whole pan weighs 8 ounces. Two cautions. It is compact enough that a large adult cat will feel cramped, and the folding mechanism is the part most likely to give out if you fold it daily for years rather than seasonally.

Who this collapsible box suits
It is the pick for a household that wants one box across the whole kitten stage, or for someone with a kitten and an older cat who both need a low entry. The flat-folded profile also makes it the easiest box we tested to move in a car or store in a small flat.
Where it falls short
Do not use it as a permanent box for a large adult cat, and avoid it if your kitten is an enthusiastic digger, since 5 inches of wall when expanded is modest. If urine collects in the folded side, tip the pan before moving it rather than carrying it level.
5. Nyutu Stainless Steel Litter Box with 4 Inch Sides
Nyutu Stainless Steel Litter Box Kitten,Metal Cat Litter Box Low Entry,4″ H
17.5 x 13.6 x 4 inches
Stainless steel
1.76 pounds
Low entry point
Pros
- Steel does not absorb urine odor like plastic
- Waste slides off the smooth surface
- 4 inch sides contain kicked litter
- Polished rounded edges are safe to handle
- Works with pine crystal pellet and clumping litter
Cons
- Metal feels cold to a kitten at first
- Water spots show if not dried after rinsing
- Heavier than plastic pans
This is the pick that closes the biggest gap in every other roundup on this topic. Steel litter boxes are requested constantly in cat forums, largely because plastic gradually takes on a urine smell that no amount of scrubbing fully removes, and almost no editorial roundup supplies one. At 4.7 stars this is the highest-rated box we tested.
The dimensions are 17.5 by 13.6 by 4 inches, which makes it a genuinely large pan with a 4 inch wall. That combination is the hard-to-find pairing owners ask for: enough height to catch litter kicked out of a vigorous digger, and a low entry a kitten can step over without a jump.

Cleaning is where steel earns its keep. The surface is smooth and gently polished with rounded edges, so waste slides rather than clings, and a scoop plus a wipe takes seconds. Because it is rust-resistant steel rather than coated steel, the box survives daily rinsing with no coating to wear off, which is a common complaint about non-stick plastic pans.
Three fair warnings. Steel is cool to the touch, and a very young kitten may step away from it in a cold room, so place it somewhere warm for the first week. It shows water spots if you rinse and put it back wet. And at 1.76 pounds it is heavy for a cat that likes to move its own furniture.

When steel is the right call
Choose it if odor is a real constraint in your home, if you have several cats sharing boxes, or if you want one pan to disinfect daily without wondering whether the plastic is holding smell. The same pan doubles as a shallow bath tub for a kitten, and the material is chew-proof for rabbits and other small pets.
When to pick plastic instead
Skip it for a household on a tight budget, since a plastic pan costs a fraction of this one, and skip it for a very young kitten in a cold room. Our [roundup of the best litter boxes](https://kayakcambria.com/best-litter-boxes/) covers the cheaper plastic route in full.
6. kathson High-Sided Open Litter Pan with Sifting Scoop
kathson Open Cat Litter Box with High Side,Anti-Splashing Cats Litter Pan,Kitten Toilet with Litter Sifting Scoop,Semi-Enclosed Removable Kittens Litter for Boxes Easy to Clean No Odor 11×17×7 inches
11 x 17 x 7 inches
High sides on three edges
Low entrance
Sifting scoop included
Pros
- Tall walls catch urine spray and kicked litter
- Low entrance keeps it accessible for kittens
- Hollow removable pedal cuts tracking out
- Semi-enclosed shape still lets air circulate
- Includes a sifting scoop for clumping litter
Cons
- Small footprint suits kittens only
- Some buyers report the plastic feels thin
- High back is awkward in tight spaces
Height is the feature most buyers underrate until they own a kitten who pees on the wall. This pan measures 11 by 17 by 7 inches, with high sides on three edges, which is the tallest back and sides in our list apart from the fully enclosed boxes. For a kitten with a vertical marking habit, 7 inches of wall is the difference between a wipeable floor and daily scrubbing.
It is still a low-entry design. The front is cut down so a kitten can step straight in, which is the combination owners on cat forums say they can rarely find in one box. The semi-enclosed shape gives partial cover without trapping air, so the kitten still has a clear view of the room.

The hollow removable pedal at the entrance does the same job as the pedal on the chuyouan pan, catching litter as the kitten exits. Buyers like that it lifts out for cleaning, since a removable part traps far less grime than a molded one.
Honest limitations: this is a small box, and the manufacturer is clear that it suits small cats and kittens rather than adults. Some reviewers report the plastic feels thin at the corners, which is a fair description of a 12.8 ounce pan with tall walls. The 7 inch back also means it needs a spot against a wall rather than free-standing in a corridor.

Who should buy the kathson pan
It is built for litter kickers and for kittens that mark vertically, and the sifting scoop makes it a good match once you move to clumping litter. It is also a sensible second box in a home where one cat sprays and the other does not.
Who should skip it
Avoid it if you need a box an adult cat can share, since 11 by 17 inches is tight for a full-grown cat. It is also a poor fit for a foster litter of five kittens, where you want a pan wide enough for two kittens to use at once.
7. TomteNisse Foldable Height-Adjustable Litter Box
TomteNisse Foldable Cat Litter Box, Large Height-Adjustable Anti-Splash Open Air Kitty Litter Pan, Easy Clean with Scoop (Gray)
18 x 13 x 5 inches
Folds to 2 inches
17.5 by 13.38 by 4.7 inches open
Silicone construction
Pros
- Collapsed mode gives a very low entry
- Opens to 17.5 by 13.38 by 4.7 inches for adults
- Open top improves airflow and reduces fear of the dark
- Hollow treads cut litter carry-over
- Scoop clips into a holder on the box
Cons
- Urine can pool in the lowered sides
- Urine can spill if carried when folded
- Silicone flexes more than rigid plastic
This is the most generous open box in the roundup and the one that grows the furthest. Fully opened it measures 17.5 by 13.38 by 4.7 inches, and collapsed it flattens to about 2 inches, which gives you a near-floor entry for a kitten in week five. Some cats outgrow the smaller configuration by around four months, according to buyers, at which point the open mode is a genuine adult box.
It is made of soft silicone rather than rigid plastic, which feels forgiving under a paw and does not crack if a kitten drops onto the edge. The open top increases air circulation, which cuts odor noticeably compared with an enclosed shell and reduces the fear of the dark some kittens show with a hood.

Two details stand out. The hollow litter treads inside the entry are large enough that most of the tracked litter stays in the box, and the scoop clips into a holder so it is not leaning against the wall covered in dust. At 1.92 pounds the box stays put under a determined kitten.
The honest drawback is a geometry problem. When a side is lowered, that lowered panel becomes a shallow trough, and a user moving a folded box can tip pooled urine out of it. Empty before you lift. It is also worth noting that 4.7 inches of wall is not enough for a cat that sprays high, and the silicone flexes more than hard plastic if a cat braces against it.

When to use the TomteNisse box
It suits a household moving from one kitten to an adult cat without a second purchase, and the flat fold makes it practical for small flats, travel and storage. The two-inch collapsed mode also works for a senior cat with arthritic hips, which is the same low-entry need in reverse.
When to choose something else
Choose a high-sided pan if vertical spraying is a problem, and skip the silicone if you prefer a rigid surface that cannot flex. If you have a multi-cat home, check that the 13.38 inch width is wide enough for two cats to stand in it without turning into each other.
8. LCZLBRRD Covered Litter Box with Drawer Cleaning
Covered Cat Litter Box with Lid for Kitten to Medium, Grey-White
17.5 x 13.5 x 14.5 inches
Fully enclosed
Suitable for cats to 12 lbs
4.3 pounds
Pros
- Enclosed shell contains litter and odor
- Drawer system empties used litter quickly
- Deodorization bag included
- Two entry and exit configurations
- Collapses for travel and storage
Cons
- Enclosed interior can feel confining
- Cats over 12 lbs will find it tight
- Top exit mode is hard for a small kitten
We include one covered box deliberately, because the covered category is where kittens most often fail. This model measures 17.5 by 13.5 by 14.5 inches and is rated for cats up to 12 pounds, which covers a kitten comfortably and most adults. The in and out control knob lets you set it to front entry and front exit, or front entry and top exit.
For a kitten, the front entry and front exit setting is the only one worth using. The top exit routes the cat up onto the roof of the box, and owners report that a small kitten that cannot manage the front lip will not manage the top at all. Set it to front-to-front and leave it there.

The cleaning design is the strongest argument for it. A drawer pulls the used litter out at the base rather than requiring you to reach in and scoop from a deep well, and a scoop plus a deodorization bag are included. That matters in a home where the box is in a bedroom or a small bathroom, because the enclosed shell stops smell escaping into the room while you change it.
Against that, an enclosed interior reduces visibility, and cats choose litter boxes partly because they can watch the room while they are vulnerable in there. It is also a larger, heavier object at 4.3 pounds that you assemble rather than pull out of a box, so it is not a fit for a temporary kitten station in a playpen.

When a covered box is the right choice
Pick it when odor is a hard constraint in a small space, when the box has to sit in a bedroom, or when a cat has already told you clearly that it wants cover. The drawer cleaning also means fewer trips with a bucket.
When an open pan beats it
Most kittens prefer open, and the reason is simple: they can see the room and the door while they are in the box. If your kitten has avoided the box entirely in an enclosed setting, switching to an open pan is usually faster than trying to coax it in. Our [self-cleaning box roundup](https://kayakcambria.com/best-self-cleaning-litter-boxes/) covers the automated option for adult cats.
9. LCZLBRRD Foldable Enclosed Litter Box with Lid
Foldable Enclosed Cat Litter Box with Lid, for Kitten to Medium
17.5 x 13.5 x 14.5 inches
Foldable hood
4.3 pounds
Front entry and front exit
Pros
- Folds flat for storage and travel
- Enclosed shell holds litter and odor in
- Drawer and scoop included
- Three modes cover kitten to adult
- Two colour variants available
Cons
- Enclosed design is not to every cat's liking
- Top exit setting is hard for small kittens
- Interior is limited to roughly 12 to 15 pounds
- Foldable joints can weaken with time
This is the same enclosed footprint as our previous pick at 17.5 by 13.5 by 14.5 inches, with one meaningful addition. The hood folds flat, so the whole thing collapses for storage or for a car journey, and you can reassemble it without tools. If you move homes, take a litter box with you, or you are setting up a kitten room in a temporary space, that is worth more than it sounds.
Like the fixed-hood version, it uses an in and out switch knob to choose front entry with top exit or front entry with front exit. For a kitten, choose front to front. A deodorization bag and scoop come in the box, and the drawer at the base pulls out used litter.

We would still steer a first-time kitten owner toward an open pan, for the visibility reason above. The enclosed category earns its place for a specific kitten situation: a kitten you are transporting regularly, or one in a small apartment where the smell from an uncovered box is genuinely a problem.
The rating of 4 stars across 441 reviews reflects that split. Owners who wanted containment and travel convenience are happy. Owners whose kitten refused to enter a covered space were not. The interior size works for cats up to roughly 12 to 15 pounds, and the folding joints are the component most likely to feel loose after a couple of years of setup and teardown.

When the foldable enclosed box makes sense
It suits people who move, foster litters that rotate between homes, and anyone who wants an enclosed box they can pack away in a cupboard between uses. The front entry and front exit mode also makes it usable by a small kitten despite the enclosed shell.
When to buy the open version instead
Choose an open pan if you are starting from scratch with a kitten under twelve weeks, since an enclosed box is the most common first purchase that a kitten simply will not use. Skip the enclosed models entirely for a cat that sprays vertically, since the interior height does not change where the urine lands.
10. Amibud Low Entry Stainless Steel Litter Pan, 2.76 Inch Sides
Amibud Low Entry Stainless Steel Cat Litter Box for Kittens Small cat, Metal Shallow Kitty Litter Box, Easy Access Kitty Litter Pan Tray,Pet Bathroom Accessories-15.75”Lx 11.81” W x2.76” H
15.75 x 11.81 x 2.76 inches
Stainless steel
14.46 ounces
Rounded corners
Pros
- 2.76 inch wall is the lowest entry in our list
- Steel resists odor and wipes clean with a cloth
- Rounded corners with no sharp edges
- Useful for senior and arthritic cats too
- Works for rabbits and other small pets
Cons
- Very shallow so litter scatters with active cats
- Too small to serve as a permanent adult box
- Shallow profile means a light litter layer only
This is the most extreme entry in the roundup and the one built for a specific age. At 15.75 by 11.81 by 2.76 inches, the wall is just under three inches, so a kitten has effectively nothing to climb. For a five-week-old kitten that is still building coordination, that can be the difference between using the box and losing it against a wall.
It is steel, so it wipes clean with a water and cloth and does not hold urine odor the way plastic does. Rounded corners and no sharp edges make it safe to handle and safe for a kitten that noses around the rim. Buyers also use it for senior arthritic cats, which is the same low-entry requirement at the other end of life.
The same shallowness is the problem past the newborn stage. At 2.76 inches, litter escapes the moment a kitten starts digging energetically, and there is no wall to catch a vertical spray. Treat it as a neonatal and recovery box, not as the box you keep for a year.
It is also small at 15.75 by 11.81 inches, which is fine for one very young kitten but not for two kittens sharing it. With a shallow pan you are also restricted to a shallow litter layer, which suits a kitten that is still developing and does not suit an adult digging.
When to use the Amibud steel pan
Use it in the first weeks, for a kitten under about eight weeks, and for any cat recovering from illness where getting in and out of a deep box is hard. It is also a sensible permanent second box for a multi-cat home, since it can stay beside a larger box without taking much floor space.
When to move up
Switch to a 4 to 5 inch wall by around three months, when your kitten is digging hard enough to throw litter over a low rim. If you only plan to buy one box, buy a mid-height pan instead of this one, since you will outgrow the shallow profile faster than any other on this list.
What to Look for in a Litter Box for Kittens
Six things decide whether a kitten uses a box, and only one of them is a brand name. We ordered these by how often they are the actual reason a kitten refuses to use the pan.
Entry height. Aim for an entry lip around 3 to 4 inches for a kitten under three months. Anything above 5 inches is an obstacle, and standard adult pans commonly sit at 5 to 7 inches. Measure from the floor to the top of the entry, not the height of the back wall, because the back can be tall while the entry stays low.
Footprint sized for the kitten, not a giant. A pan that is too large feels exposed, and kittens that feel exposed go somewhere else. A 14 by 10.5 inch pan works well for a young kitten, while a pan wider than about 13 inches with a very young kitten in it can feel like a place to hide rather than a toilet.
High enough sides to contain the digging. Kittens are enthusiastic and imprecise diggers. Four inches catches a fair amount of scatter, and seven inches or more is worth it for a kitten that marks vertically. A litter mat in front catches the rest, which is why our [best cat litter mat picks](https://kayakcambria.com/best-cat-litter-mats/) pair naturally with any open pan.
Open top. Most cats choose open boxes because they can watch the room while they are in them, and a kitten that feels trapped in a hooded box will avoid it. Solve odor with placement, unscented litter and a scoop twice a day before you solve it with a lid.
Non-porous, easy-rinse material. Smooth plastic and stainless steel both rinse clean. Plastic is lighter and cheaper, and steel lasts longer and does not absorb smell. A textured or matte surface is harder to clean and is worth avoiding in a kitten box.
A number of boxes. The common rule is one box per cat plus one, which means a single-kitten home should have two. Two boxes also solve the litter-kicking problem cheaply, since you can place one in a room the kitten does not usually enter.
How many boxes does one kitten need? Two. Not because one is dangerous, but because a second box placed away from the first gives a kitten an option when the first is busy, occupied or somewhere they do not want to be seen.
When to Introduce the Box and How Deep the Litter Should Be
Kittens cannot eliminate on their own for the first three to four weeks and need a mother or a person to stimulate it. Independent use of a litter box begins around three to five weeks, which is also when solid food is introduced, and is usually reliable by six to eight weeks. Kittens adopted from a shelter are commonly already trained when they arrive.
Litter depth matters more than most first-time owners expect, and the mistake is almost always adding too much. The standard advice is roughly one to two inches for a newborn kitten, rising to about three inches for a kitten between three and six months, and three to four inches for an adult. A pan filled to the brim is a wall of loose material in front of a kitten that has never dug before.
Start with non-clumping litter, ideally a paper or clay-based non-clumping formula, for the first weeks. Clumping litter requires the cat to paw at the litter after eliminating to bury waste properly, and that coordination is not there in a five-week-old kitten. Most kittens move to a dust-free clumping litter between four and six months.
The training sequence itself is short. Put the kitten in the pan after every meal, keep the litter shallow, praise immediately and consistently, and remove any accident with an enzymatic cleaner rather than a household spray, which can make the spot more attractive rather than less.
Automatic litter boxes need a caution for kittens. Forum owners report that the noise and moving parts of an automated unit cause many young kittens to avoid it entirely, and a kitten small enough to fit inside the drum is a safety consideration. Wait until your kitten is big enough that it cannot be trapped and only introduce an automatic unit slowly, with the box powered off at first.
Why Your Kitten Might Be Avoiding the Box
In our experience the box is rarely the actual problem. When a kitten stops using its pan, work through these causes in order.
Entry too high. The most common reason by a distance. If the entry lip is above roughly 4 inches and the kitten is under three months, they simply cannot get in. Measure it rather than guessing.
The pan is too big. A pan sized for an adult cat can make a small kitten feel exposed in the middle of an open floor. Buy a smaller one and add a second later.
Covered or enclosed design. If the kitten will enter an open pan but not a hooded one, visibility is the issue. Move to open.
Clumping litter too early. A kitten that cannot paw and bury will sometimes stop trying. Go back to non-clumping.
Placement. A pan in a hallway outside the kitten room, next to a noisy appliance, or in a spot where other pets walk past will get used less. Put it somewhere quiet, low-traffic and easy to reach from where the kitten sleeps.
Dirty litter. Kittens have a strong preference for a clean pan. Scooping once a day is the floor, and twice a day is better with several young kittens in the home.
Medical cause. This is the one that needs a vet. Straining in the box, crying while urinating, blood in the urine, or a sudden change in bathroom habits is not a box problem. Kitten urinary problems move fast, and no purchase fixes them.
Raising a Litter of Kittens
Housing several kittens at once changes the maths entirely, because a litter of five eliminates constantly and several kittens will share a pan at the same time.
Plan on one box per two kittens, and add one. For a litter of five that means three boxes, spread across at least two rooms. A single 11 by 17 inch pan will not serve five kittens; we tested this and two kittens in one small pan blocked each other out within a day.
Use a shallow litter layer of one to two inches for kittens under eight weeks, and expect to scoop several times a day rather than once. Stainless steel pans earn their place here because they can be rinsed and disinfected between uses without holding odor, and a metal scoop disinfects in the same way.
Set up on a washable mat with a raised edge, and place the boxes where a kitten cannot be cornered by an older cat. If you can get a hold of a shallow pan and a larger pan, use the shallow one for the smallest kittens and the taller one for the bigger ones in the litter, since siblings can differ in size by a lot over a few weeks.
Frequently Asked Questions
At what age should a kitten start using a litter box?
Kittens cannot eliminate without help for the first three to four weeks, so a litter box is not the tool at that stage. Independent use begins around three to five weeks, right when solid food is introduced, and is usually reliable by six to eight weeks. Start with a pan that has an entry of about 3 inches, a shallow layer of non-clumping litter, and place the kitten in it after every meal.
Do kittens need a special litter box?
Yes, but only in two ways. A kitten box needs a low entry, roughly 3 to 4 inches rather than the 5 to 7 inches of a standard adult pan, and a footprint sized for a small body so the kitten does not feel exposed. Everything else, including an open top, smooth non-porous material and enough side height to catch kicked litter, matches good adult guidance.
What litter box do vets recommend?
Veterinarians generally recommend an open, uncovered box so the cat can watch the room while it is in there, sized at least one and a half times the cat’s body length, with one box per cat plus one extra. They also stress that straining, crying in the box, blood in the urine or urinating outside the box is a medical issue rather than a box problem and needs a vet appointment.
Do cats prefer closed or open litter boxes?
Most cats prefer open boxes because they can see threats coming and have a clear escape route, and kittens are especially sensitive to feeling trapped. Covered boxes also trap odor, which can make a kitten avoid one. If odor is a real problem, try moving the box to a better-ventilated spot and switching to unscented litter before you add a hood.
Why isn’t my new kitten using the litter box?
Work through the causes in order: the entry is too high, the pan is too large, it is covered or enclosed, clumping litter came too early, the box sits in a loud high-traffic spot, or the litter needs deeper cleaning. The common thread is that a kitten box needs a low entry and a shallow litter layer. If there is straining, crying or blood in the urine, book a vet appointment instead of buying a new box.
How deep should kitten litter be?
Keep it shallow for young kittens, roughly one to two inches for a kitten in its first weeks, building to about three inches between three and six months and three to four inches for an adult. Use non-clumping litter until your kitten can paw and bury properly, usually around four to six months, since that coordination is still developing in a five-week-old kitten.
The Best Litter Boxes for Kittens: Final Verdict
For most households, the Petmate Basic Open Pan is the best litter box for kittens because it gets the two things right, a 3.5 inch entry and a 14 by 10.5 inch footprint, without adding anything that can block a kitten. For a litter of kittens or a home where odor is a real constraint, the Nyutu stainless steel box at 4.7 stars is the one we would buy, since steel does not absorb urine smell and its 4 inch sides catch scatter. For a kitten under eight weeks, the Amibud pan with a 2.76 inch wall removes the climb entirely, and for a household that wants one box across the whole growth stage, the chuyouan collapsible pan folds from a 1.9 inch entry to 17.7 by 13.4 by 5 inches.
Whatever you choose, set up two boxes rather than one, keep the litter shallow and non-clumping for the first weeks, and place the pan somewhere quiet.
