Our Verdict
The IRIS USA Large Open-Top Litter Box is our first choice in this five-box comparison because its 19 x 15-inch footprint, high side-and-back shield, open access, and included scoop make it the most broadly useful design here. The IRIS USA Top-Entry Litter Box ranks second for cats that already use a top entrance and homes that need stronger scatter containment. Cats have their own preferences, though. A published study found no overall preference for covered or uncovered boxes among the 27 cats analyzed, while a minority clearly preferred one style. Fit, access, cleaning, and your cat’s response matter more than a sweeping claim about one design being best for every cat.
This is a researched comparison, not a hands-on test. We checked the exact product identities already attached to this article, compared official specifications where an exact manufacturer page was available, and used veterinary and peer-reviewed guidance for the broader advice. We did not measure scatter, odor, leak resistance, durability, or dog resistance. Those limits are important: a lid can contain kicked litter without controlling odor, and a top opening may discourage some dogs without making a box universally dog-proof.

Why these three lead: the IRIS open-top box offers uncomplicated access plus a removable shield; the IRIS top-entry box puts containment ahead of easy entry; and the Amazon Basics box keeps a familiar front entrance while adding a hood and swinging door. That is a useful range of layouts, not a claim that every cat will accept each one.
Quick Comparison — All 5 Finalists
| Rank and product | Design | What the source confirms | Best fit | Main limitation |
|---|---|---|---|---|
| #1 IRIS USA Large Open-Top | Open pan with removable high shield | 19 x 15 x 11.75 inches; scoop included | Most adult cats; owners who want open access with higher sides | Front entry and open top still allow some tracking and exposure |
| #2 IRIS USA Top-Entry | Deep top-entry box with grooved lid | 20.47 x 16.14 x 14.56 inches; scoop and non-skid feet included | Agile cats already comfortable with top entry | Poor fit for cats that cannot or will not jump through the lid |
| #3 Amazon Basics Hooded Enclosed | Front-entry hood with swinging door | Exact listing identifies a standard 21 x 16 x 15-inch box with a door and odor-control feature | Cats that accept a hood and front flap | The listing does not prove real-room odor performance |
| #4 WoofiGo Stainless Steel Enclosed | Stainless pan with high plastic enclosure | Exact marketplace listing identifies an XL pan, lid, high sides, scoop, and tracking step | Owners specifically seeking a metal pan and high walls | No trustworthy exact-model manufacturer page was found |
| #5 Petmate Basic Litter Box | Small, low-sided open pan | Small variant is 14.05 x 10.5 x 3.5 inches and weighs 0.5 pound | Kittens, small cats, or an accessible secondary pan | Too small for many adult cats |
Our Research Methodology
We kept the existing five products, ranking, and ASIN order. For each box, we looked for an exact-model page from the manufacturer or another official first-party page. IRIS and Petmate provide useful specifications for their products. The exact Amazon Basics page is the official marketplace listing, although it did not expose full product copy to our research tool; we therefore stayed close to the exact listing title and the product data already tied to ASIN B075357QFB. For WoofiGo, we found no trustworthy exact-model manufacturer page, so we treat the marketplace title and AAWP product record as seller-supplied information rather than independently established performance.
We compared five practical points: usable size, entry style, wall and lid layout, included parts, and cleaning access. We also checked the advice against Cornell Feline Health Center guidance and a peer-reviewed covered-versus-uncovered litter box study. We did not use buyer-review counts, star ratings, transient prices, or manufacturer promises as proof of performance. Product dimensions and included accessories can also change by color or size variant, so confirm the selected option before ordering.
#1 IRIS USA Large Open-Top Litter Box — Best Overall
- MADE IN USA: Our Open Top Litter Box offers a functional solution to your cat's bathroom needs. With the open-air, getting in and out of the tray has never been easier for your cat and the tall walls keep any litter or spraying inside the tray.
- PRIVATE: This open air cat litter tray offers privacy for your cat with tall walls that form the scatter shield, offering the privacy of a hooded cat litter box with the easy access and cleaning of an open air kitty litter pan.
- EASY CLEAN: This litter box’s durable construction and removable components make maintenance effortless. With minimal seams, litter won’t get stuck, allowing for a quick clean that keeps your home fresh and tidy.
- OPEN TOP & TIDY: The open top design offers easy monitoring of your cat's habits and health, while providing ample space for quick accessibility. With tall walls to minimize litter scatter, you'll enjoy less cleanup and reduced waste of litter or pellets overall.
- GREAT SIZE: Dimensions: 19"L x 15"W x 11.75"H
The first-ranked IRIS keeps the basic open-pan layout but adds a removable shield around the sides and back. On its official product page, IRIS lists the full unit at 19 x 15 x 11.75 inches and the interior at 15.3 x 12 x 11.6 inches. The page also confirms a matching scoop, polished interior, molded feet, and a design made in the USA. Those are concrete reasons for its #1 spot: it gives an adult cat open access while putting more wall between kicked litter and the floor than a shallow pan does.
The shield should not be read as a scatter guarantee. Litter can still leave through the lowered front, stick to paws, or be kicked over an edge. The interior measurement also matters more than the word “large” in a title. Measure your cat and the intended floor space rather than assuming the label settles the fit. If your cat is older, recovering from an injury, or reluctant to step over an entry, compare the front height with a low-sided pan before buying.
Who It’s For
Choose this for an adult cat that prefers an open view and for a household that wants higher side coverage without a hood. Skip it if your cat needs the lowest possible step-in or if you expect an open box to hide waste or contain room odor.
Pros & Cons
- Official dimensions and interior measurements are available
- Open layout makes scooping and visual checks simple
- High side-and-back shield addresses kicked litter without adding a roof
- Matching scoop is included
- Lower front remains an exit path for tracked or kicked litter
- No hood or filter
- The stated interior may still feel cramped to a very large cat
#2 IRIS USA Top-Entry Covered Litter Box — Best Enclosed
- Reduce Litter Tracking & Keep Floors Cleaner: The top-entry cat litter box features a textured lid that helps remove loose litter from your cat's paws before they leave, minimizing litter scatter and helping maintain a cleaner home. Ideal for pet parents searching for a mess-free cat litter box and litter tracking solution.
- Enhance Privacy While Controlling Odors: The enclosed cat litter box design creates a private, secure space for cats while helping contain odors inside the box. Perfect for households looking for an odor-control cat litter box, covered litter box, or privacy litter box for cats.
- Help Keep Dogs Out of the Litter Box: The elevated top-entry design makes it difficult for curious dogs to access litter, helping keep your cat's space protected. A smart solution for multi-pet homes seeking a dog-proof cat litter box and cleaner litter area.
- Easy Cleaning & Convenient Maintenance: Designed for quick access and hassle-free scooping, this durable plastic litter box simplifies daily cleaning routines so you can spend less time maintaining and more time enjoying your pets. Ideal for shoppers seeking an easy-to-clean litter box with convenient scoop access.
- Space-Saving Dimensions: Measuring 20.5" L x 14.75" W x 14.38" H, this large top-entry cat litter box provides ample interior space for daily use while maintaining a compact footprint that fits easily in laundry rooms, bathrooms, and other pet-friendly spaces.
This IRIS changes the route in and out: the cat enters through the lid instead of a front doorway. IRIS lists the unit at 20.47 x 16.14 x 14.56 inches, with a 17.5 x 13.5-inch bottom at its narrowest point. The official product page confirms a grooved lid intended to knock litter from paws, non-skid rubber feet, and a scoop that hangs from the lid. High walls provide a physical barrier around the litter area. That makes the design a sensible second pick when containment matters and the cat is a willing jumper.
We would not call it dog-proof. A top entrance may deter a dog that cannot reach or climb into it, but that depends on the dog’s size, persistence, and the box’s placement. Nor can we promise odor control. IRIS says the high walls and lid help minimize smells, but we did not test that claim, and a covered box can hold odor where the cat experiences it. Daily scooping still matters. The biggest practical drawback is access: kittens, older cats, and cats with mobility limitations may struggle with a top entry.
Who It’s For
Pick this for a mobile cat that already accepts top-entry boxes and an owner who prioritizes high walls and a litter-catching lid. Skip it for a cat with limited jumping ability or any cat that has shown discomfort with enclosed toilets.
Pros & Cons
- High walls surround the litter area
- Grooved lid is designed to catch particles from paws
- Official page provides exterior and interior dimensions
- Scoop and non-skid feet are included
- Requires the cat to jump onto and through the lid
- Covered interior can retain smells if cleaning slips
- Not proven dog-proof
#3 Amazon Basics Hooded Enclosed Litter Box — Best Hooded Option
- EASY ACCESS FOR CATS: The swinging plastic door allows your cat to enter and exit the hooded cat litter box with ease while keeping the interior mess contained
- ODOR CONTROL: The litter boxes feature a pre-installed carbon filter, reducing unpleasant odors, with replacement filters sold separately for continued freshness
- STAIN AND ODOR RESISTANT: The covered litter box is crafted from durable plastic that resists stains and odors and provides a clean and hygienic environment for your furry friend
- SPACIOUS ENCLOSED DESIGN: This enclosed litter box provides your cat a private space, offering a comfortable area to do their business in peace
The exact Amazon Basics listing for ASIN B075357QFB identifies a standard 21 x 16 x 15-inch hooded litter box with a swinging door and an odor-control feature. The product record tied to this article identifies a pre-installed carbon filter, with replacements sold separately. Unlike the IRIS top-entry box, this one gives the cat a conventional front route. It ranks third because it may suit cats that accept a hood but do not use an opening in the roof.
The words “odor control” describe the listed feature, not a result we verified. A filter does not replace frequent waste removal, and the swinging flap is another variable: some cats use it without concern, while others avoid a moving door. The standard footprint may also be restrictive for a long or broad cat. If acceptance is uncertain, introduce the box without forcing the flap and keep the previous box available while you watch which setup the cat chooses.
Who It’s For
This is for a cat that prefers front entry and has already shown it will use a hooded box. Skip it for a very large cat, a cat that dislikes flaps, or a household looking for documented odor-removal performance rather than a listed filter feature.
Pros & Cons
- Front entry avoids the jump required by a top-entry box
- Hood and swinging door are identified in the exact listing
- Carbon filter is listed as included
- Published dimensions make space planning easier
- Odor performance was not independently verified
- Some cats reject a flap or enclosed interior
- Filter replacements add upkeep
#4 WoofiGo Stainless Steel Enclosed Litter Box — Best Stainless-Steel Option
- 【Extra Large Size】 The XL stainless steel litter box measures 23.62" X 15.75" X 12.01", providing a spacious space for big cats while being suitable for cats of all sizes, the extra large size makes it the best choice for multi-cat households
- 【Why Choose Stainless Steel Litter Box!】 Open top stainless steel cat litter box made of high-quality ABS enclosed high wall enclosure and stainless steel litter pan, unlike plastic litter boxes, stainless steel litter boxes with high sides do not collect any residue or odor, are easily to clean, have strong and durable, and never rusty
- 【5.98" High-Sided Enclosure, Reduce Mess！】The height of the extra large stainless steel cat litter box is 12.01", with a unique curved high wall design, to protect your cat's privacy and prevent litter spilling and urine leaking. The tracking-proof pedal further prevents litter from being carried out, ensuring a mess-free indoor environment even with a naughty cat
- 【Secure Buckle Connection】The stainless steel cat litter pan is tightly connected to the high wall by a buckle, more stable connection, and no need to worry about the shell falling off
- 【Better Solution】 If you are tired of the odor from the cat litter after your cat pees, please buy this stainless steel litter box to solve your problem. WoofiGo believes it will be your last cat litter box. If you have any questions, please contact WoofiGo; we will do our best to solve your problems
WoofiGo is the only stainless-steel pan in this group. The exact marketplace record for ASIN B0C5XR973C identifies an XL enclosed litter box with a metal pan, high-sided enclosure, lid, scoop, and tracking step. Its product data gives dimensions of 23.5 x 15.6 x 13 inches and describes a buckle connection between the pan and upper shell. On paper, that combination gives a large cat more length than the smaller plastic pans in this lineup and gives high urination or vigorous digging more surrounding wall.
The evidence is thinner here. We found no trustworthy exact-model manufacturer page to confirm the marketplace copy, and we did not test the pan. The seller’s title says it “never absorbs odors” and describes anti-leakage performance, but we do not treat either absolute as established fact. Stainless steel is a different surface from plastic and may appeal to owners who want a metal pan, yet seams, the plastic enclosure, litter choice, and cleaning frequency still affect the day-to-day result. Verify the current dimensions and included parts on the selected listing before buying.
Who It’s For
Consider this if you specifically want a larger stainless-steel pan with high surrounding walls and accept weaker source documentation. Skip it if you need a fully manufacturer-verified model, a lightweight box, or proof of odor and leak performance.
Pros & Cons
- Only metal pan among the five finalists
- Marketplace record identifies an XL footprint and high enclosure
- Scoop and tracking step are listed
- Buckle connection is described between the pan and shell
- No trustworthy exact-model manufacturer page found
- Odor and leak claims remain unverified seller claims
- Metal construction may be heavier and noisier than a basic plastic pan
#5 Petmate Litter Pan — Best Simple Low-Entry Pan
- OPEN-TOP KITTY LITTER BOX: This small cat litter pan provides ample space on all sides for cats to do their business comfortably, and is great for small cats or kittens to access
- KEEPS LITTER CONTAINED: This small cat litter box features a wide base to keep mess contained within the pan for litter-free floors It features a rim on all sides to easily lift move the pan Dimensions: "14 x 10.5"

The Petmate Basic is a plain open pan, and its small size is the reason to choose it as well as the reason it ranks fifth. Petmate’s official product page lists the small Mouse Gray version at 14.05 x 10.5 x 3.5 inches and 0.5 pound. The marketplace title attached to this ASIN rounds the first dimension differently, so confirm the selected variant. Petmate describes open access from any side, low rimmed sides, a wide-profile base, and US manufacture using its EcoTech resin.
That low 3.5-inch height can make entry easier for a kitten or a cat that struggles with tall walls. Cornell likewise notes that kittens and older cats with arthritis may need sides low enough to enter easily. The trade-off is obvious: this small pan gives an adult cat little turning room and puts very little wall between litter and the floor. We see it as a kitten pan, an accessibility-led choice for a small cat, or a secondary box, not the default toilet for a large adult.
Who It’s For
Choose the small Petmate for a kitten, a small cat that needs low entry, or a compact secondary station. Skip it for a large adult, a high sprayer, or a cat that kicks litter hard.
Pros & Cons
- Low entry is easier to step over than high-sided designs
- Official size and weight are published
- Open pan is easy to inspect and scoop
- Simple shape has no lid, flap, or filter to manage
- Small footprint is unsuitable for many adult cats
- Low walls provide little scatter or spray containment
- No scoop, hood, or tracking surface is identified

Buying Guide: How to Choose a Cat Litter Box
Start with usable space, not the size label
“Large” and “XL” are marketing labels, not shared standards. Compare the interior floor area, doorway, and lowest entry point with your cat’s body and movement. A box has to leave room to enter, turn, dig, and settle without hanging over the edge. Exterior dimensions tell you whether it fits your room; interior dimensions tell you whether it fits the cat. If a manufacturer publishes only the outside measurement, allow for walls that taper inward.
Match the entrance to the cat
Low-front pans reduce the step for kittens and cats with limited mobility. High-sided open boxes trade some accessibility for better physical containment. Top-entry boxes demand the most jumping and turning. Cornell says most cats prefer simple boxes without hoods, but that is broad guidance rather than a rule for every animal. If your cat’s habits change suddenly or entering the box appears painful, contact a veterinarian instead of treating the box purchase as the whole solution.
Do not assume covered means preferred
The covered-versus-uncovered study in this guide analyzed 27 cats after offering both styles for 14 days. Nineteen showed no preference, four preferred the covered box, and four preferred the uncovered box. The boxes were large and scooped daily, so the result does not prove that any hooded retail box will work for any cat. It does support a practical approach: offer a real choice when changing styles and pay attention to the box the cat actually uses.
Treat odor control as a cleaning routine
A hood, filter, or metal pan may change how odor moves or how a surface cleans, but none makes waste disappear. The published study discusses at least daily cleaning, and Cornell advises keeping boxes clean and changing litter frequently. Scoop on a reliable schedule, wash the box with products appropriate for its material, and follow the litter and box manufacturers’ care instructions. Strong fragrance can be unpleasant to cats, so masking odor is not the same as maintaining a clean toilet.
Plan for more than one cat
Cornell recommends as many boxes as there are cats, plus one. That means three boxes for two cats. Put them where each cat can reach a clean option without being blocked by another animal. Buying several compact pans is not helpful if each is too small for the cats using them, so balance box count with usable dimensions and placement.
FAQ
Are covered litter boxes better than open boxes?
Not for every cat. In a controlled study of 27 analyzed cats, most showed no preference, while four preferred covered and four preferred uncovered boxes. A large, clean box and the individual cat’s behavior matter more than a blanket rule.
How often should a litter box be scooped?
Daily scooping is a sensible baseline. The covered-versus-uncovered study used daily scooping, and Cornell warns that cats may avoid an unclean litter-box area. A multi-cat home may need more frequent attention.
How many litter boxes do two cats need?
Cornell recommends one box per cat plus one, so two cats would have three boxes. Spread them across usable locations rather than making one corner the only toilet area.
Is a top-entry litter box dog-proof?
No top-entry box should be treated as universally dog-proof. The opening and high walls may deter some dogs, but access depends on the dog’s size, reach, and persistence. Placement and supervision still matter.
Does stainless steel eliminate litter box odor?
We found no exact-model manufacturer evidence that the WoofiGo box eliminates odor, and we did not test it. Stainless steel changes the pan surface, but waste, litter, seams, attached plastic parts, and cleaning frequency all affect odor. Claims such as “never absorbs odors” should be read as seller language, not a guaranteed result.
Final Verdict
The IRIS USA Large Open-Top Litter Box (B0CKLYW5GY) stays at #1 because its official dimensions, open access, tall shield, and included scoop make the fewest assumptions about how a typical adult cat enters and exits. Choose the IRIS USA Top-Entry (B0768H1181) only when your cat can manage the lid opening, or the Amazon Basics Hooded Box (B075357QFB) when a familiar front entrance is the better enclosed format. The WoofiGo (B0C5XR973C) is the metal-pan option, with weaker source documentation, while the small Petmate Basic (B00L369CXQ) is best reserved for cats that genuinely benefit from its low entry and compact footprint.
