A kitten under eight weeks can’t clear a 5-inch wall, and that’s the detail most open litter box lists skip. The best open litter box for kittens has a low front entry, walls tall enough to hold in scatter, and a base that won’t slide when a small cat launches into it.
We compared five open-top litter boxes on listed entry height, wall height, footprint, material and what’s in the box. Four are stainless steel and one is a collapsible plastic tray. Steel wins on odor and scratch resistance. But every metal pan here is at least 5 inches tall, so the smallest kittens need the collapsible option, a ramp, or a few weeks of growing first. If you’re still planning your whole setup, start with our indoor cat litter box guide.

⚡ Quick Verdict
Quick Answer: What Makes a Good Open Litter Box for Kittens?
- Entry height: about 2 to 3 inches for kittens under 8 weeks. Up to 5 inches is usually fine once they climb and jump well.
- Wall height: 5 to 8 inches holds in most scatter. Taller walls help diggers, but they raise the climb-in height unless the front is cut low.
- Size: roughly 1.5 times your kitten’s body length is the usual target. Buy for the adult it will become if the entry is low enough (our guide on how to choose an open litter box shows how to size it).
- Base: anti-slip pads or a rubber mat underneath, so the box stays put.
- Surface: non-porous steel or smooth plastic that you can wash without scratching.

📋 How We Evaluated
We compared the manufacturer specs on each listing: entry height, wall height, footprint, material and included accessories. Then we read buyer feedback for repeat complaints such as sliding, scatter and noise. We didn’t run lab odor tests, so the scores rank how well each box fits a kitten, not how it performs under instrumentation.
Detailed Reviews
TENTIZON Stainless Steel Cat Litter Box for Kittens and Medi🏆 Editor’s Pick

| Material | Stainless Steel |
| Dimensions | 17.3 x 13.4 x 7.8 inches |
| Entry Height | 5 Inches |
| Included Accessories | Mat, Scoop, Lid |
What We Found
Of the five boxes here, this is the only one that lists a front entry height (5 inches) and the only one that ships with a mat, a scoop and a lid. That’s why it tops the list. The 7.8-inch overall height keeps most scatter and spray inside, which matters once a kitten discovers digging.
Stainless steel doesn’t soak up urine the way a scratched plastic tray can. Wipe-down cleaning is quick, and the included dual-layer mat catches a good share of the litter that would otherwise ride out on paws. The lid uses an overlap buckle. You can snap it on for a covered setup or leave it off to run the box open, which is how we’d start a kitten.
One honest caveat. Five inches is a real step for an 8-week-old kitten, and a 4-week-old won’t manage it at all. Read the entry height table below before you buy.
💬 My Take
Best all-in-one kit on the list, with one limit: the 5-inch entry suits kittens that already climb and jump, not newborn-stage litters.
Who It’s For
New kitten owners who want mat, scoop and lid in one purchase, and whose kitten is roughly 8 weeks or older. Medium-sized adult cats also fit, so the box doesn’t expire when the kitten grows.
It also works in small bathrooms at 17.3 by 13.4 inches. For a senior cat with stiff joints, 5 inches is borderline, so measure first or see our guide to the best open litter box for senior cats.
✅ Pros
- Mat, scoop and lid included, so there’s no second shopping trip.
- Stainless steel doesn’t hold odor the way worn plastic can.
- Lid is optional, so the box works open or covered.
❌ Cons
- Costs more than a basic plastic tray.
- Metal is louder when a cat digs.
- 5-inch entry is too tall for kittens under about 6 to 8 weeks, and only one size is offered.
Tevila Stainless Steel Litter Box with Scoop,Small Metal Pan🥈 Runner-Up

| Material | Stainless Steel |
| Dimensions | 17.32 x 13.39 x 7.87 inches |
| Stability Features | 4 Anti-Skid Pads |
| Cleaning Method | Water Rinse |
What We Found
Slipping is the complaint that ruins a lot of kitten litter boxes. A kitten sprints in, brakes, and the pan scoots across the tile. This Tevila has four anti-skid pads on the base to stop that.
The open top lets air move, so ammonia doesn’t pool the way it can under a lid. A scoop comes in the box, and the smooth steel rinses clean with water. It has no mat, so budget a few dollars for one (here’s our pick of the best litter mat for open litter boxes).
Size is almost identical to the TENTIZON (17.32 by 13.39 by 7.87 inches). The listing doesn’t state an entry height, so confirm the front profile before you count on it for a small kitten.
💬 My Take
The most stable metal pan here. Pick it over the TENTIZON if your floors are slick and you’d rather add your own mat.
Who It’s For
Owners with hardwood or tile floors and a kitten that treats the litter box like a launch pad. Multi-cat homes also benefit, because stainless steel survives daily scooping and frequent washing.
People with allergies often prefer a non-porous surface because it doesn’t hold dander or smell. Renters like that a steel pan is easy to wash and unlikely to stain.
✅ Pros
- Four anti-skid pads keep the pan in place during active use.
- Non-porous steel doesn’t hold odor like worn plastic.
- Open top gives good airflow.
❌ Cons
- No litter mat in the box, so tracking control costs extra.
- Heavier than plastic, which makes moving it for cleaning a chore.
- Plain industrial look won’t suit every room.
Tevila Stainless Steel Cat Litter Box for Kitten, Kitty & Se💵 Budget Pick

| Material | Stainless Steel |
| Dimensions | 17.13 x 13.19 x 5 inches |
| Wall Height | 5 Inches |
| Safety Feature | Smooth Rounded Edges |
What We Found
This is the shortest metal box on the list at 5 inches, and that cuts both ways. Kittens get in more easily and air flows freely. A digger or a high-spraying cat will also fling litter over the side sooner.
The edges are rounded, which is nice when you lift a pan full of litter with one hand. The footprint (17.13 by 13.19 inches) is the smallest of the metal pans, so it slides under a sink or into a bathroom corner.
Read the price on the listing, since we can’t promise it stays the cheapest. What we can say is that it’s the lowest and most compact stainless option here. Shopping on price alone? See our full list of the best budget open litter boxes.
💬 My Take
Good for tight spaces and small kittens, with the trade-off of more scatter. Pair it with a mat.
Who It’s For
Apartment dwellers short on floor space, and owners who want a metal pan without paying for the larger kits. The low profile helps very young kittens.
It works as a second box in another room, and some people also use this size for ferrets or other small pets.
✅ Pros
- Compact footprint fits small bathrooms and under-sink spots.
- Lower price than the kit-style boxes, based on the listing at the time of writing.
- Rounded edges are easier on hands and paws.
❌ Cons
- Low walls mean more scatter when a kitten digs hard.
- Less litter capacity, so you’ll scoop more often.
- Growing kittens may feel cramped sooner.
Idymere Stainless Steel High Sided Cat Litter Box

| Material | Stainless Steel |
| Dimensions | 16.93 x 12.99 x 5.12 inches |
| Versatility | Multi-Pet Compatible |
| Edge Design | Smooth Rounded |
What We Found
The name says high sided. The listed height says 5.12 inches, which is about the same as the Tevila budget pan and 2.7 inches shorter than the TENTIZON. So expect moderate containment, not a tall wall.
Where it pulls ahead is flexibility. The listing pitches it for rabbits, ferrets and small cats, and the steel surface dries quickly between washes. Rounded edges make it safe to carry.
Wash it with warm water and mild soap. Skip chlorine bleach on any stainless pan, since chlorides can pit the surface over time.
💬 My Take
A solid pan for mixed small-pet homes. Nothing in it is kitten-specific, and that’s the reason it sits fourth.
Who It’s For
Households with a rabbit or ferret alongside a cat, who want one pan style for everyone. It’s also easy to sanitize, which helps if you’re caring for a sick animal.
The listing mentions use as a small tub too, which could appeal if you want dual-purpose gear.
✅ Pros
- Works for several small species, so it’s flexible.
- Fast-drying steel makes washing and reuse quick.
- Rounded edges are safer to handle.
❌ Cons
- Walls are 5.12 inches despite the High Sided name, so scatter control is only average.
- Smaller footprint may feel cramped for larger kittens.
- No mat or special tools in the package.
chuyouan Collapsible Kitten Litter Box Low Entry Small Cat L🧳 Best for Travel

| Material | PP and TPR |
| Expanded Size | 17.7 x 13.4 x 5 inches |
| Folded Height | 1.9 Inches |
| Special Feature | Collapsible Design |
What We Found
This is the only box here that gets under the 2 to 3 inch entry guideline for very young kittens, and it does it by folding down to 1.9 inches. Expand it to 17.7 by 13.4 by 5 inches as the kitten grows.
It’s plastic (PP with a flexible TPR hinge), so it’s waterproof and light. A removable pedal mat catches litter from paws. The same folding trick makes it easy to pack for a vet visit, a trip, or a rescue litter.
The trade-off is longevity. Flexible joints take stress with every fold, and plastic holds odor longer than steel. We’d treat it as a starter or travel box, not a ten-year pan. If you want a low-profile plastic tray as a long-term option, read our Catit open litter tray review.
💬 My Take
The best pick for the youngest kittens and for travel. Plan to add a rigid box later.
Who It’s For
Anyone with a kitten under about 6 weeks, plus travelers who need a litter box that packs flat. Volunteers who take in kitten litters will like the easy storage between uses.
It also works as a backup box in a second room.
✅ Pros
- Folded height of 1.9 inches suits the smallest kittens.
- Collapses flat for travel and storage.
- Waterproof material rinses clean.
❌ Cons
- Flexible joints can trap odor more than a solid metal surface.
- 5-inch walls when expanded let energetic cats scatter litter.
- Plastic won’t last as long as stainless steel.
What to Look For Before Buying?
Kittens aren’t small cats. They’re clumsy, they misjudge jumps, and a bad first litter box experience can turn into accidents on your rug. Four specs decide most of it.
Check Entry Height Versus Wall Containment
Measure your kitten’s shoulder height, then compare it to the entry. For kittens under about 8 weeks, aim for an entry of 2 to 3 inches. Walls need to stay tall enough to catch spray and flung litter, which is why some boxes cut a low door into a tall wall.
Use the table below as a rule of thumb. Kittens vary, so watch yours. If it hesitates, hops in sideways or avoids the box, the step is too tall.
| Kitten Age | Typical Entry Height | What Works |
|---|---|---|
| 3 to 4 weeks (starting to explore litter) | Under 2 inches | Shallow tray or a folded collapsible box like the chuyouan |
| 4 to 8 weeks | 2 to 3 inches | Low-entry box, or a taller box with a small ramp or step |
| 8 to 12 weeks | 3 to 5 inches | Most kittens manage a 5-inch entry such as the TENTIZON |
| 12 weeks and older | 5 inches and up | Any box on this list, sized for the adult cat |
Value Material Hygiene And Longevity
Stainless steel doesn’t hold urine odor the way scratched plastic can. Plastic gets micro-scratches from scoops and claws, and bacteria and smell settle in them. Steel rinses clean and lasts years. It costs more up front, and it’s louder underfoot and in the pan.
If you’re torn, think about replacement costs. A plastic tray you swap every year may cost more than one steel pan in the long run. Tight on budget? Compare more affordable pans in our list of the best budget open litter boxes.
Look for Stability and Safe Edges
Kittens sprint, brake and dig. A light box slides on tile and a kitten learns to fear it. Look for anti-slip pads, or plan to place a rubber mat under the pan. Rounded or rolled edges matter too, because burrs on cheap metal can scratch paws or hands.
Verify Space Constraints And Placement
Measure the spot first. Leave room to lift the box and scoop from the side. Compact pans like the Tevila budget model suit bathrooms, while larger ones work better in a laundry room. Open boxes breathe better than covered ones, but they still need airflow around them. Worried about smell? We answer that directly in do open litter boxes smell?
Open vs. Covered Litter Boxes for Kittens
Most vets and behaviorists lean toward open boxes for kittens. They’re easier to enter, easier to clean, and the kitten can see what’s coming. Covered boxes hold in scatter and hide the view, which owners like, and some cats find dark and cramped. For a wider look at the trade-offs, read our open litter box pros and cons.
| Feature | Open Box | Covered Box |
|---|---|---|
| Kitten access | Easy, with nothing to push through | Flap or door can scare a small kitten |
| Airflow and ammonia | Better airflow, less buildup | Traps gas, so it needs frequent scooping |
| Litter scatter | More likely to spill over the sides | Fewer stray granules |
| Privacy | Low | High |
| Cleaning | Quick, with easy visibility of waste | Lid comes off, an extra step |
Our take: start open, and add a lid only if scatter bothers you and your kitten is comfortable. The TENTIZON is the one box here that lets you do either.
What Litter to Use in an Open Box for a Kitten?
Kittens put things in their mouths. Many vets suggest avoiding clumping clay litter for the first couple of months, often until about 8 to 12 weeks, because a kitten that eats it can get a blockage. Ask your vet about your own kitten.
- Safer starters: paper pellets or non-clumping litters without added fragrance.
- Later: switch to clumping if you prefer it, mixing the new litter in over about a week.
- Depth: around 2 inches is the usual starting point. Metal pans can ring with shallow litter, so a little more depth helps.
- Skip: scented litter, because strong smells can put kittens off using the box.
How to Set Up and Train a Kitten on an Open Litter Box?
- Pick a quiet spot. Keep it away from food and water, and out of loud areas like the washer.
- Add about 2 inches of litter. Use something unscented and kitten-safe (see above).
- Place your kitten in the box after meals, naps and play. Those are the moments they most often need to go.
- Let them dig on their own. If needed, gently move a paw through the litter once. Don’t force it.
- Reward success. A quiet word or a small treat works. Never punish an accident.
- Add a step or ramp if the kitten struggles with the entry, or switch to a lower box for a few weeks.
- Scoop daily and wash the pan weekly. Add a second box if your home has more than one floor.
How to Clean a Stainless Steel Litter Box?
- Scoop clumps or waste every day. Twice a day is better for a single young kitten.
- Once a week, empty the whole pan.
- Wash with warm water and a mild unscented dish soap. A strong scent can keep a cat from using the box.
- Use a soft sponge. Steel wool and rough pads scratch the surface.
- Skip chlorine bleach. It can pit stainless steel over time.
- Dry fully before refilling, so the new litter doesn’t clump on damp metal.
Troubleshooting: Common Open Litter Box Problems
| Problem | Likely Cause | Fix |
|---|---|---|
| Litter ends up on the floor | Low walls or vigorous digging | Add a textured litter mat for open litter boxes, or move to a taller box such as the TENTIZON |
| Box slides around | Slick floor and a light pan | Use anti-skid pads or a rubber mat underneath |
| Kitten hesitates at the entry | Step is too tall | Use a ramp, or a lower box like the chuyouan folded |
| Loud digging in a metal pan | Hard surface and thin litter | Add more litter depth and a mat beneath |
| Accidents outside the box | Dirty box, new litter or wrong spot | Scoop more often, go back to the old litter, and move the box to a quieter place |
| Sudden change in habits | Possible health issue | See your vet, since urinary problems often start with accidents |
Kitten Litter Box Buying Checklist

- ☐ Non-slip base or a mat to go under it
- ☐ Smooth, rounded edges
- ☐ Walls tall enough for my kitten’s digging style
- ☐ I measured the spot where it will go
- ☐ Unscented, kitten-safe litter is ready
- ☐ One box per cat plus one extra, if I can
Frequently Asked Questions
Is an open litter box good for kittens?
Yes, for most kittens. Open boxes are easier to climb into, let air circulate and make it simple to see when the pan needs scooping. The trade-off is more scatter, so pair one with a litter mat made for open boxes.
How low should the entry be on a kitten litter box?
Aim for about 2 to 3 inches for kittens under 8 weeks. Older kittens usually manage 5 inches. If your kitten hesitates, use a ramp or a lower box.
At what age do kittens start using a litter box?
Kittens usually start exploring litter around 3 to 4 weeks old. Many are using a box reliably by 8 weeks, though accidents are normal along the way.
When should kittens move to an adult-sized litter box?
Move up when your kitten can’t turn around comfortably or hangs over the edge. A box about 1.5 times their body length is the usual target, and many owners buy a larger box with a low entry from the start. Our guide on how to choose an open litter box covers sizing in more detail.
Are stainless steel boxes safe for declawed cats?
Yes, smooth metal can be gentler on sensitive paws than rough plastic. Check that all edges are finished without burrs, and use a soft litter. Metal feels cold, so watch how your cat reacts at first.
How often should kitten litter boxes be cleaned?
Scoop at least once a day, and twice is better. Empty and wash the pan weekly. Dirty boxes are a common reason cats start going elsewhere.
Can collapsible boxes serve as permanent solutions?
They work best as travel, temporary or starter boxes. Flexible joints wear with daily folding and plastic holds odor longer, so a rigid pan is the better long-term pick.
Do open boxes cause more odor than covered ones?
No, usually less. Open designs let air flow, which cuts ammonia buildup, while covered boxes trap it. How often you scoop matters more than the box style. For the full breakdown, see do open litter boxes smell?
How many litter boxes does a kitten need?
The common rule is one box per cat plus one extra. For a single kitten in a multi-level home, put a box on each floor.
Can I use a cardboard box lid as a temporary kitten litter box?
Yes, as a stopgap. A shallow lid has a very low edge that tiny kittens can step over. Replace it when it gets damp, because cardboard soaks up urine and doesn’t hold up.
🎯 Final Verdict
Get the TENTIZON if your kitten is about 8 weeks or older. It’s the only box here with a mat, scoop and lid included, and the 7.8-inch walls hold in more mess than the shorter pans. If your kitten is younger than that, start with the chuyouan folded flat, then move up.
Choose the Tevila Runner-Up if your floors are slick and sliding is the bigger risk. The Tevila budget and Idymere pans are fine second boxes, and each has walls just over 5 inches, so keep a mat nearby.
