Finding the Best Litter Boxes for High Spraying Cats: An 18-Year Testing Journey
**This post contains affiliate links and I will be compensated if you make a purchase after clicking on my links.
There is a particular kind of frustration that comes with walking into a room only to find a puddle behind a perfectly clean litter box. If you live with a cat who prefers to stand while they pee, you know that standard boxes—even many hooded versions—often fail to contain the mess.
Over my 18 years of living with Ragdolls, especially with high-sprayers like Murphy and Caymus, I’ve spent more time than I’d like to admit cleaning up “leaks” that escaped through side seams or over low walls. That experience led me to a deep dive search for the most effective litter boxes for high spraying cats. My goal was to identify designs that solve the “stand and pee” problem by focusing on seamless construction and high walls, ensuring urine stays exactly where it belongs: inside the box.

How We Tested: 18 Years of Experience
Since 2008, I’ve been testing cat products with my Ragdolls. Dealing with “high-sprayers” like Murphy and Caymus taught me very quickly that a standard litter box often fails the real-world test. When a cat stands up to pee, the mess typically ends up in the “seam” where the hood meets the base, or worse—directly on your walls.
For this guide, I evaluated each litter box based on:
- Wall Height: Can it contain a standing pee-er?
- Seam Placement: Are there “leak points” where the top and bottom meet?
- Sanitation: Is the plastic high-quality and easy to scrub clean?
- Cat Comfort: Is there enough “turn-around” room for a large breed?
I looked for specific designs that eliminate common leakage points while ensuring a large cat has the space they need to feel safe and comfortable.
I am aware of a few litter boxes for high-spraying cats, but there are other ways to create a DIY litter box that works for high-peeers. This page will have all the information you need to find the correct box for your high peer. But high-sided litter boxes for cats are also great for controlling litter scatter, so even if you don’t have a high-pee-er, everyone can benefit from these litter boxes.
IMPORTANT – This article discusses cats that aim high when urinating in their litter boxes, not spraying due to hormonal issues.

My mom’s Ragdoll cats, Caymus and Murphy, peed almost standing up; as they peed, they’d lift their hindquarters. In contrast, my Ragdoll cats, Charlie and Trigg, remain in a squatting position throughout urination.
My mom had to get high-sided litterboxes because of Caymus and Murphy.
When I discovered high-sided litter boxes also helped keep the litter inside the box, that was another reason I wanted some.
We previously reviewed the NVR Miss litterbox, which I love. However, NVR Miss litterboxes weren’t high enough for my parents’ cats.
My parents purchased a plastic storage container, similar to a Rubbermaid model. This video shows the boxes my mom chose, but it’s of Caymus rolling around in his litterbox.
It’s worth noting that high-sided cat litter boxes offer several advantages over other types, including less dust escaping from clay clumping litter; it often hits the sides of the box and settles back down.
Does Your Cat Need a Tall Litter Box for High-Spraying?
When considering a high-sided cat litter box, ask yourself a few questions. There may be a fixable reason for your cat spraying urine high, which can be resolved without replacing the litter box.
- Has your cat only high-sprayed once, or is it becoming a habit? If your cat is typically a squatter but has been sprayed once, you’ll want to wait to see if it happens again. It might have been an accident if it were just that one time. Or it could be peeing outside of the box for medical reasons. Check out our post about cat peeing outside the litter box if the issue persists.
- Is the cat’s litter pan clean? Sometimes, cats protest when their litterboxes have a buildup and are not cleaned promptly enough. And, as you may have guessed, one of their preferred methods is making a mess to make it impossible for you to miss the smelly litterbox.
- Is another cat using its litterbox? If two cats share the same litterbox, one might retreat to the remaining clean areas to use the litterbox. This might make it adopt an abnormal position and, as a result, pee high and make a mess.
- Is there anything wrong with your cat’s legs? If your cat is suddenly peeing high, it might not be able to squat as it usually does. Examine your cat’s legs and paws to see if there is a painful area. Keep an eye out for signs that it adopts a squatting position outside the litterbox. If it does, then this is certainly not the reason.
- Does your cat have trouble peeing? Sometimes, when cats experience pain during urination, they may adopt unnatural positions. This might make them pee high even if they typically do not. Observe the cat to determine whether it is experiencing any urination issues.
If your cat is a high-sprayer, don’t worry, you are not alone! Please review the comments for solutions other pet owners have used to address their cats’ excessive spraying.
Best High-Sided Litterboxes for Large Cats
If your cat is a high-sprayer, you’ll need a different type of litter box. Again, there are numerous options available to you.
Before you replace your litter box, you may prefer to convert your existing one to a high-sided model. You can do this with plastic shields that fit onto your existing litter box.
You can buy a three-pack of shields that lets you add a protector to the sides and back of the box using self-adhesive Velcro strips. The shields add an extra 11.5 inches to your cat’s litter box.
Cat Litter Box Pee Shields and Splash Guards Offer:
Pee shields and splash guards for litter boxes offer a customizable and effective way to contain litter scatter and high-aiming urine. Here are their general features:
- Modular Design: These shields are typically composed of individual panels and connectors, enabling a customizable and expandable setup.
- Easy Assembly: The pieces click or snap together, making for a straightforward assembly process.
- Sturdy Connectors: They use robust connectors to ensure a stable, secure structure.
- Configurable Shapes: You can arrange the panels in various configurations, such as a U-shape or an enclosed space, to accommodate different litter box sizes and designs.
- Splash Guard Functionality: Their primary purpose is to contain litter scatter and splashes, helping keep your floors clean.
- Aesthetic: Panels are often white, providing a clean, neutral look that complements most home decor styles.
However, there are other good options available, including a MEEXPAWS Splashguard and a curved pee shield from Deapher.
You can browse other pee shields/litter box converters on Amazon as well.
How Do I Know if It’s Tall Enough?
Measure your cat’s height – from the floor to where they eliminate. Then account for at least 2 inches of litter (or however much you use). The sides of the litter box you choose need to be taller than the sum of those two measurements. For example, my cats measure about 10 inches, plus 2 inches for litter. I want a litter box with walls at least 13 inches high.
Below is a deeper dive into all the best litter boxes for high-spraying cats currently on the market. If you know of any others you’ve had success with, let us know!
1. Use a Storage Bin as a Litterbox
My mom found a very good solution to the high-spraying problem: she used a storage bin as a high-sided litter box. We’ve found it is one of the best litter boxes for messy cats, as it’s easy to find and meets all the requirements for her tall cat.
Here’s an idea of the type of box she has and uses for her cats:
If you opt for a storage bin, look for one with flat interior sides. This prevents caking clumps of pee in various nooks and crannies, making them impossible to remove. For example, look at the design of the black storage boxes in the photo above.
If cats pee in the corner, it’s rounded and curved, and it’s impossible to get a clump of pee out with a litter scoop, so get a squared bin with no dips or dents. There are many options on Amazon. After having the black ones above, my mom went with clear ones for her multi-cat household.
Of course, the problem with this one is that once your cat becomes elderly or has jumping issues, they may be unable to enter the box or will struggle to do so. Please see the other options below if you have a senior cat.
Things To Keep In Mind When Choosing a Large Plastic Storage Bin for Your Litterbox:
- Choose one with flat sides (as mentioned above)
- Pay attention to the height – keep in mind that your kitty will be jumping in and standing on 2-3 inches of litter. Subtract those 2-3 inches from the height, as that is the height your kitty will have to pee standing up. Ensure the box is positioned higher for your standing pee-er so the urine flows into the box.
- Note the length – is it long enough for your cat to move around in (do circles in) to do their business?
- A transparent material is best – a transparent or translucent storage box will make a less intimidating litter box for your cat. Cats like to be in control of their whereabouts at all times, so they may hesitate to get into a box that they can barely see out of.
- Watch the edges – always ensure the box you get does not have any sharp edges, because it might hurt your cat. Run your hands over the storage bin to ensure it is smooth.
- Durability – Litter boxes get a lot of use, so be sure to get something durable that won’t crack.
- Accessibility – Is your pet a senior cat with mobility issues? A top-entry litter box with high sides can be more rigid for them to access, so you may need to find one with a door as an entry and exit point.
If you have a larger cat, then a large litter box may not be enough. You may need an extra-large litter box with high sides to keep big cats happy – they don’t like to be penned into a small space.
Choosing a suitable extra-large litter box comes with a couple of additional criteria as well:
- Finding floorspace – ensure you have sufficient space for the litter box in a location that your feline friend is comfortable with. Larger boxes can sometimes occupy high-traffic areas in your home, making your cat less comfortable using them. It’s even more of an issue if you live in a multiple-cat household with kitties who don’t want to share. Try to find a secluded space for the larger boxes if you can.
- Easy access – the larger the litter box, the harder it can be for cats to get into it. Especially with older cats, you should consider improving access if they require an extra-large box – either by adding smaller steps up to the box or by cutting a sizable entrance for low entry that’ll fit your larger cat. Just be aware that a larger entry means a higher chance of litter being kicked out by your cat’s paws. You may need a litter mat to contain the litter in the litter box area.
- Cleaning – cleaning becomes more challenging when you have an extra-large box – there’s more space to scoop. Choosing the right scoop makes cleaning easier because it’s faster to find clumps.
With larger litter boxes comes the risk of odor control issues if you don’t stay on top of cleaning. It may be worth investing in an air purifier to trap odors; place it near the large litter boxes to help prevent odors from spreading to the rest of your home. Ensure you get one with a carbon filter, as this will work more effectively – I have suggestions below.
Here are a few storage boxes I found on Amazon that might work great as litterboxes:
- Homz Plastic Storage, Modular Stackable Storage Bins with Blue Latching Handles, 66 Quart, Clear, 2-Pack
- Rubbermaid Cleverstore Clear 71 QT Pack of 4 Stackable Large Storage Containers
- IRIS USA 132 Quart Large Storage Bin – see examples of using this plastic bin as a litter box for high-spraying cats below. Some readers say this is the best storage bin for litter boxes.
2. Horizon Poly Products Kat Kave Litter Box
- High Walls: Helps contain litter scatter and keep floors clean.
- Spacious Design: Allows cats to move freely and comfortably.
- Seamless Design: Makes cleaning easier and helps prevent odors.
- Privacy and Security: Provides cats with a sense of privacy and security.
- Ideal for Specific Households: Suitable for multi-cat households or homes with larger breed cats.
- Less Frequent Cleaning: Requires less frequent cleaning due to its spacious design.
This cat cave litter box is tall enough to accommodate even the tallest cats, or it has easy access if your cat doesn’t squat to pee. Plus, it has an enclosed space where the cat can pee, meaning it can spray as high as it wants without any urine on your floor.
The top lid is easy to remove for you but not for your cat. It will stay fixed while the cat is inside, but you can easily lift it to clean the litter box.
If you look at the Kattails Kat Kave Litter box, you will notice that it looks a lot like the storage bin my mom uses. The main differences are that it also has a top and an opening.
This is important, especially if your cat is fussy around the litterbox because it makes it more accommodating. As for the top lid, this helps contain the odor from the litterbox inside. It will also contain the litter scatter and keep your floors cleaner.
Tip from a Floppycats’ Reader
@oliveradorableragdoll sent this photo, stating, “I got it for Oliver, who can pee over an 11” litter box. It is so large, I keep 4” in front of the entry hole litter-free & they use the back of the box. I’ve had it for about two years & it has worked fine for me. You can see where Oliver is in the back-right corner. I am retired, so I can keep the litter away from the entry hole. It would probably be challenging for those who work outside the home. But I find my kitties have their favorite place to go in the litter box, so it’s pretty much a habit once they get used to going at the back of the box. I clean the box twice a day.”
“The Kat Kave is essentially the professional version of my mom’s DIY storage bin. Because it’s one solid piece of molded plastic, there’s no ‘seam’ halfway up the wall. For a high-sprayer, this is the Holy Grail—there is simply nowhere for the urine to leak out. It’s bulky, but it’s a ‘set it and forget it’ solution for peace of mind.”
3. Doggy Bathroom
As the name suggests, this litter box is designed for pups and dogs rather than cats. Still, sometimes unconventional solutions are needed, and this is one such option that could work for your high-spraying cat.
It’s a high-sided litter box that’s 16 inches tall, made entirely from 100% recyclable plastic. They’re manufactured in Canada and designed not just to be effective but pretty stylish too, or at least as stylish as a litter box can be – there are different color options for the base, and you can get matching mats to place in front.
The entrance is relatively low, so it’s good if your cat likes to turn around once they enter the litter box – otherwise, they may spray out of the front. The low entrance will also likely mean you’ll see some litter scatter, but it is a good choice for kittens or arthritic cats who don’t want to step up to get into their box.
The Doggy Bathroom is designed to be used with Pee Pads for dogs, which adhere to the sides and absorb urine, with baking soda inside the pad to help dampen the odor. You could use these with your cat, along with litter for poop, or rely on the litter to capture urine that falls down the sides, wiping them clean when you scoop the litter.
“Don’t let the name fool you! While designed for dogs, many cat owners find success with this for high-sprayers. The height is incredible, and the side entry is low enough for seniors while keeping the ‘spray zone’ completely walled off. It’s a clever choice for those who need maximum vertical protection.”
4. Smart Paws Litter Box or TownTime Extra Large Litter Box with High Sides
The Smart Paws litter box is an extra-large, low-entry model. It’s another simple option your cat can use with ease, and provided they don’t aim themselves out of the entry, it should help prevent issues with cats spraying too high.
And because it’s an otherwise open litterbox, it won’t intimidate the cat – they’ll be able to use it while still keeping an eye on their surroundings, unlike some enclosed litterboxes.
The box’s rounded edges and slightly extended sides provide a handle, making it easy to pick up for cleaning. And as a nice touch, those handles have an embossed fish design.
“If you’re looking for something that doesn’t look like a construction bin in your guest bathroom, the Smart Paws is a lovely choice. It has a polished finish that’s much easier to clean than rougher plastics. While the sides are high, very tall sprayers might still clear the top, so this is an ideal option for ‘medium’ sprayers or those who just want to stop litter scatter.”
The TownTime Extra Large Litter Box with High Sides is a spacious, practical solution for cat owners looking to minimize mess and ensure their feline companions have a comfortable bathroom experience. While its price may be slightly higher than some standard litter boxes, its size, convenience, and anti-scatter design could be worth the investment for cat owners dealing with litter tracking.
Size: Measuring 25.27″ L x 17.83″ W x 13.11″ H, this litter box offers ample space for even the biggest felines to move around and use the restroom comfortably.
Anti-Scatter Design: High sides and a no-gap design help contain litter mess, preventing it from being kicked or tracked outside the box. This keeps your floors clean and eliminates the need for constant sweeping.
Easy Cleaning: Made from smooth polypropylene, the TownTime box is seamless and easy to wipe or rinse. Plus, its size allows for easy scooping and waste disposal.
“The TownTime is a solid option for those who want a storage-bin-sized box without the DIY effort. It’s significantly larger than most pet store offerings, making it a great fit for larger cats who need a wide turning radius. The high sides are molded as one piece, which is exactly what we look for to prevent leaks.”
5. Gefryco Jumbo High Wall Litter Box
Offering ample space for your feline friends, the Gefryco Jumbo Cat Litter Box with High Sides is an excellent choice for multi-cat households or large cat breeds. This extra-large litter box features high walls to help contain scattered litter and prevent messy splashes. Made of durable, BPA-free plastic, the one-piece molded design is easy to clean and features a low entry point for easy access.
“What I love about the Gefryco is the sheer depth. For multi-cat households, you need that extra-large footprint so no one feels cramped. The one-piece design is a huge win for high-aiming kitties. Just keep in mind it’s an open-top, so you’ll want to pair it with a good air purifier if you’re sensitive to odors.”
6. Richell PAW TRAX High Wall Cat Litter Box, X-Large
Richell’s PAW TRAX XL, made in the USA, offers a spacious palace for large cats, multi-cat households, or any kitty who appreciates larger spaces to do their business. This 150% larger haven features high walls to contain messes, an anti-tracking grate step to keep floors clean, and easy access for all felines. Plus, with a sleek design and three colors, it’s the purr-fect upgrade for your home! Say goodbye to litter box blues and hello to happy cats and clean floors.
“The anti-tracking grate on the Richell is a lifesaver for long-haired cats. If you’re tired of finding litter tracked all the way to your bed, this helps knock it off their paws before they exit. It’s 150% larger than many standard boxes, making it a ‘palace’ for larger cats who need that vertical spray protection.”
7. The Frisco Jumbo Covered Cat Litter Box
Another solution for a high-walled, covered litter box is this Jumbo Frisco product. It measures 29.7″ long by 17.5″ wide and is 17.6″ tall, with a hinged lid.
It has a side door rather than an option at the end, and it includes an inner cat litter tray and a scoop holder with a scoop that sits in one of the handle gaps on the side.
Some of the main features of the Frisco high-sided cat litter box are:
- The high-sided walls prevent any spraying or litter scattering.
- The door has a low entrance just six inches from the ground and is big enough for most cats to get through comfortably.
- The hinged lid can be left closed for privacy and to help control odors, opened for cleaning, or completely removed if your cats prefer the extra light.
- It’s made from a lightweight, BPA-free plastic that wipes clean.
However, some reviewers haven’t had the best experience with it. Many have said the inner tray isn’t deep enough. If you only put litter in that, the cat will spray urine along the sides. While it’ll be contained in the larger box, the urine pools under the tray and is harder to clean.
Other reviews have noted that the material is flimsy and the hinged cover is not sufficiently secure. However, it is designed to be easily removable, so you can take the lid off if you prefer. Still, it doesn’t click into place. It could be accidentally removed entirely when you only meant to open it.
Because it has side handle holes, some customers have reported cat urine seeping through the gaps.
With that in mind, here are some tips on how to use the Frisco Jumbo litter box to get the most out of it:
- Don’t use the inner litter tray – too many people complain it’s too shallow and that it causes a mess. Instead, use the entire jumbo box as the litter tray. Fill the entire bottom with litter, and you get one large, enclosed litter tray; any spray will trickle into the litter to clump, or it can be wiped from the sides.
- If you do that, add a mat outside the doorway to prevent litter tracking. Or, if you do keep using the inner tray, consider using the extra space for a small mat inside the box.
- Tape up the handles on the sides where there are gaps if you don’t intend to move them around a lot. This can prevent urine from being sprayed out unintentionally.
- Ditch the scoop that comes with the litter box. It’s a standard scoop with flat tines, so you have to spend much longer sifting or discarding litter that could be reused. The scoop holder is fine, but consider a Swift’R Sift’R Kitty Scooper.
“My big tip for the Frisco Jumbo: ditch the inner tray! Many readers found that urine pools underneath it, creating a cleaning nightmare. If you use the entire jumbo box as the tray itself, it becomes a much more effective high-sided solution. Just watch those side handle gaps—a very precise ‘corner sprayer’ might find them!”
8. Frisco Top Entry Litter Box
In general, I am not a fan of top-entry litter boxes. They are considered hooded litter boxes, and if they are not kept clean, they can smell terribly. And if a cat’s litter box smells unpleasant, they’re less likely to use it.
Even if it is a problem for the human nose, it’s a bigger problem for a cat.
If you order a top-entry litter box to try, be sure to measure your cat against the box’s measurements.
This Frisco Top Entry Cat Litter Box on Chewy is the largest I have seen.
Another reason I am not a fan of top-entry boxes is that, as cats age, it becomes harder for them to get in and out of the box.
“Top-entry boxes like this Frisco model are a smart choice for containing 100% of the spray. However, I always tell readers to consider their cat’s mobility. While it’s a great solution for active cats, older kitties or very large cats might find the jump-in entry a bit restrictive. If your cat is okay with the jump, it’s a total mess-saver.”
9. IRIS Open Top Litter Box with Shield and Scoop
This is the middle ground between litterboxes with and without lids. It is shaped like a regular litterbox but has an attachment that enlarges the walls, keeping a frontal spout for easy access.
It also has rounded edges on the top side of the walls. Still, unlike other products, these are rounded towards the inside, which provides better protection against litter scatter. So it’s nice that it’s high without a lid.
This one is 19.00 “L x 15.00 “W x 11.75 “H, which also suits tall cats. It even comes with a matching litter scoop and kitty litter, so you have the whole package when you order. It is easy to clean and has a high-polish finish that will make the litter slip right out.
Toni wrote in to say, “I currently have the IRIS open-top litter box, which was the best I could find – I need TALL! I would have gotten the Nature’s Miracle box, but it wasn’t tall enough. The biggest problem with the IRIS is that it snaps together to form tall sides, but pee can accumulate in the small nooks and crannies, creating a recurring cleaning issue. As for the IRIS, I put duct tape around to seal the “collection” spots, which can get a little nasty. Thank goodness for Clorox wipes!”
“The IRIS is a popular pick because it’s easy to find and budget-friendly. My one caution: keep an eye on the ‘seam’ where the shield snaps onto the base. For very determined sprayers who hit that exact line, you might still see a little seepage. It’s worth trying for moderate sprayers, but ‘power sprayers’ might need a seamless bin instead.”
10. NVR Miss
As the name suggests, the NVR Miss litterbox is designed for high-spraying cats that require specific conditions. It has a simple model with high walls and a cut-out entry so the cat can get in quickly.
It has rounded edges throughout, and the interior is easy to clean because there are no areas where urine can accumulate. The margins are also rounded across the entire litterbox surface, making it easy to lift when cleaning.
Compared to other lidless litterboxes on the list, this one is a good choice for cats that are extra picky with their litterboxes. That’s because it’s far less threatening than enclosed options, so you won’t have to worry that your cat will reject it.
NVR Miss Litterbox Review – High Wall Cat Litterbox – YouTube
“I truly love the NVR Miss for its ‘long and lean’ design—it fits in spaces other jumbo boxes won’t. However, while it’s higher than a standard pan, it wasn’t quite enough for my parents’ boys. It’s a fantastic middle-ground option for cats who aren’t full ‘stand-up’ sprayers but still manage to kick litter everywhere.”
11. Modkat Litter Tray
We reviewed the Modkat litter tray in 2018. They are great litterboxes for keeping pee inside and litter scatter, too. However, as you can see, the front is open, so if your high-spraying cat steps in and doesn’t turn around, then you will still have pee going over the side.
That’s why it’s crucial to have a water-resistant cat litter mat under it. The Modkat Litter Tray comes with a reusable liner and a litter scoop. The Modkat litter box measures 20 x 14 x 15 inches.
“Modkat is the gold standard for design-conscious owners. Their liners are a clever way to handle spray, but for some Ragdolls, the size can feel a bit snug. If your cat likes to ‘do circles’ before settling, check the measurements carefully. It’s a premium price, but the aesthetic and high-quality plastic are top-notch.”
The DIY High-Sided Bin: The Ultimate Custom Solution
Sometimes, even the largest commercial boxes don’t offer the height or floor space a big Ragdoll needs. If you have a cat like Caymus, who needs maximum room to navigate, a DIY high-sided litter box is often the most effective solution. By repurposing a large plastic storage tote (like a Sterilite or Rubbermaid bin), you can create a custom environment that is virtually impossible to spray over.
Why the DIY Route Works
- ✔ Unmatched Wall Height: You can choose a bin with 15-inch to 20-inch walls, ensuring even the most enthusiastic “stand-up” sprayer stays contained.
- ✔ Ample Space: Most storage bins offer a much larger footprint than standard litter boxes, which is essential for the comfort of larger breeds.
- ✔ Cost-Effective: A sturdy storage bin typically costs a fraction of what a specialized high-sided litter box does.
How to Create Your Own
“Charlie and Trigg taught me that ‘room to groom’ is just as important as wall height. The beauty of the DIY bin is that it’s a ‘seamless’ solution. Since it’s one solid piece of plastic, there are no cracks or joins for urine to seep into. It’s my go-to suggestion for owners who have tried every store-bought box and still find themselves cleaning up puddles. Plus, it’s incredibly satisfying to know you’ve built a custom solution that finally works!”
Here’s a discussion we had on this topic on Facebook:
DIY Litter Box – Without a Door
Check out these pictures and directions from a few Floppycats readers on how they made their own high-sided litterboxes:
Another reader, Mary, shared this post on our Floppycats Facebook Group and showed how she used the IRIS USA 132 Quart Large Storage Bin to make a homemade litter box for large cats.
Another reader saw this post and made an even higher-sided litter box using the plastic shield from the ModKat litter box above.
Lisa wrote, “Here is my new DIY litterbox. Someone posted about this litterbox iris USA 132 qt clear container. I added the mod cat splash guards. The splash guard is not perfect. So had to modify one corner. Do you know where you could buy this material to make your own splash guards to get a perfect fit? Will send pics in the next email.
In the first box, the splash guard was a splice in the corner bc, not a perfect fit. I was at work when my husband did the first box. For boxes 2 and 3 we shifted the guard a bit. So no splicing is needed. You can see the difference in the 2 boxes in the pics I sent in the 2 separate emails.”
DIY Storage Bin Litter Box With Iris Storage Bin
Much like a Rubbermaid container for a litter box, Lisa used the IRIS storage bin posted by Mary and said, “We used a saw, Dremel, utility knife, and sandpaper. Perfect fit in the litter box area. Cats love them, and they are so easy to wipe down.”
Lisa continued, “Mary posted on your site last week about this IRIS USA 132 qt box. It was exactly what I was looking for. It is completely square, all smooth no indentions or grooves. It is 28 L by 20 W and 17.6 inches tall.
My cat is talented, so I added the mod cat urine splash guards and clips. Had to use the Dremel to make slits in the rim of the box to use. I did look at the mod cat site and these are out of stock right now. It was under replacement/accessory parts on the mod cat site.”
DIY Litter Box – With a Door
I cannot remember how it came about, but Floppycats’ reader Aims Windler, in a comment on a Facebook post, posted a photo of her DIY litter box. I replied to the Facebook comment and asked her to email me with details on how they made their homemade litter box. It’s simple to make but quite effective at giving your cat privacy and helping to keep odors sealed inside a box.
You can see the full details of it on our page about How to Make a High-Sided Litter Box – DIY High-Sided Litter Box.
What do you think of this simple DIY litter box build? Have you designed your own litter box, too? We’re always happy to share readers’ designs and help others to find a litter box that works for them and their cats.
Other Products for High-Spraying Cats
If you are dealing with a high sprayer, you must pay extra attention to the litterbox area. You need the best accessories to minimize effort. Here are some of the items that will undoubtedly make your life easier:
A GREAT Litter Scoop
Swift’R Sift’R Kitty Scooper by Red Rocket Pets recently beat out my favorite cat litter scoop that reigned for over 15 years, the Litter Lifter, pictured below. You have no idea how much you will prefer the Swift’R Sift’R Kitty Scooper when using clumping litter. I hate scooping without it.
Especially when dealing with high-spraying cats, you need a good scoop to remove litter from the edges of the litterbox. With high sprayers, urine often splashes onto the walls of the litterbox or along the edges. It can also cover a larger area, making it more challenging to clean than when dealing with cats that squat when they pee. Again, this means you need a good scoop. This one used to be my favorite, but now it is a close second.
A Litter Mat
Even when using litter boxes for high-spraying cats, you will still get some litter scattered on your floor. Your cat will likely carry it on its paws even if it doesn’t come out of the box directly. So, consider using a litter mat. The Blackhole cat litter mat sells on Amazon.
Air Purifier for Cat Litter Smell
No matter how quickly you can get to scooping your cat’s litter box, sometimes you cannot avoid the cat litter smell. The Purrified Air Litter Box Air Filter helps to eliminate cat litter box smells around your litter box. Its powerful air purification technology for cat litter boxes features 53 cubic feet per minute of airflow through a 2″ thick, 2.2-pound proprietary blend of filter media that does the job like no other.

Cat Urine Destroyer
A reader on YouTube wrote, “My husband cleans [the litter box] with a special cleaner that breaks down the enzymes in cat pee, to help get the smell out, because she pees up the back wall. Ugh. It’s called Nature’s Miracle Urine Destroyer Foam. It has a strong scent, so he cleans the litter box outside, but it sure does help get rid of the pee smell!”
A Cat Litter Disposal Bin
Similar to the Litter Genie, the Litter Locker is a better-designed product that helps keep cat litter odor out of your home while you wait for trash pickup. The Litter Locker can be purchased from Paws & Claws, or you can buy the Litter Genie XL, which is the same design as the Litter Locker – just longer. The Litter Genie or Litter Locker refills will fit this. However, I like this aftermarket Litter Genie/Litter Locker refill from Firik. See our product review of the Litter Locker here.
When Standing is a Sign: Health & Behavior Considerations
While many cats are simply “natural high-peeing cats,” a sudden change in posture shouldn’t be ignored. Over my 18 years of talking with Ragdoll owners, I’ve learned that sometimes the way a cat uses the box is a “cry for help.”
Sudden Changes
If your cat has been a “squatter” for years and suddenly begins standing, it’s often a compensatory move for arthritis or joint pain.
Urinary Health
Discomfort from a UTI or crystals can cause a cat to adopt tense, unnatural positions to relieve the pressure quickly.
The “Protest” Pee
If the box isn’t clean enough, a cat may stand to avoid touching dirty litter, staying “high” to minimize contact with the mess.
Multi-Cat Tension
Cats may stand so they can keep their head above the rim to watch for “attacks” from other cats while they are vulnerable.
High Spraying Cats FAQs
Why do some cats pee standing up instead of squatting?
Many cats, including large breeds like Ragdolls, naturally prefer to stand or lift their hindquarters while urinating. For most, it’s a physical preference rather than “territorial spraying.” However, if a “squatter” suddenly stands, it may indicate discomfort, such as arthritis or a UTI, so a vet check is recommended.
What wall height is best for high-spraying cats?
Ideally, look for walls that are at least 12 to 15 inches high. This ensures that even if your cat stands fully upright, the urine stays contained. The best way to be sure is to measure your cat from the floor to the base of their tail while they are standing.
Can I teach my cat to stop peeing high?
If your cat is naturally a high-sprayer, it is much better to change the litter box than to try and change the cat. Attempting to interfere with their natural urination posture can cause significant stress, which often leads to avoiding the box entirely or developing urinary issues.
Do high-sided boxes help with litter tracking?
Absolutely. While they won’t stop tracking entirely, high walls are excellent for containing “vigorous diggers” who kick litter out of the box. They keep the mess contained to the interior, making your daily cleanup much easier.
Why is my hooded litter box leaking from the seams?
Most hooded boxes have a seam where the lid meets the base. When urine hits that gap, it leaks out. While you can use “pee shields” or enzymatic cleaners to manage the mess, the most effective solution is switching to a seamless, one-piece high-sided box or a top-entry bin.
Could a dirty or shared litter box cause high-peeing?
Yes. If a box isn’t cleaned promptly or if another cat is “guarding” the area, a cat may adopt an awkward standing position to avoid touching dirty litter or to keep an eye on their surroundings. Ensure you have enough boxes (the N+1 rule) and keep them scooped daily.
Final Thoughts: Finding Your High-Spraying Solution
Living with a high-spraying cat can be a constant battle of cleanup, but finding the right box truly changes the dynamic of your home. Whether you choose a high-end molded option like the Kat Kave or decide to build your own DIY bin, the goal is the same: keeping your cat comfortable and your floors dry.
Every cat is different—what worked perfectly for Murphy and Caymus might not be the exact fit for your kitty. It often takes a little trial and error to see which wall height or entry style your cat prefers. My best advice is to prioritize seamless designs and ample space, as these two factors solve about 90% of the leakage issues I’ve seen over the last 18 years.

Hi, I’m Jenny Dean, creator of Floppycats! Ever since my Aunt got the first Ragdoll cat in our family, I have loved the breed. Inspired by my childhood Ragdoll cat, Rags, I created Floppycats to connect, share and inspire other Ragdoll cat lovers around the world,
Just found your website and love it! I bought the ModKat flip top boxes & I like those a lot. My only complaint about them is the size – I think they should be a little taller and a little wider. If I wasn’t concerned with aesthetics I would go with a plastic tote, but I don’t have a laundry room and the litter boxes can be seen by anyone heading to the guest toilet. I do like that the ModKat boxes look better even if the function isn’t 100% to my liking.
As I side note, I saw your suggestions for litter scoops and disposal containers. I have been using the Litter Genie XL and it’s fine, but I wanted to change some things about it. Then ModKat premiered their Litter Keeper and I was sold on the look, and that I can use regular grocery store bags (which I have plenty) or their bags. I was ready to give them 4 out of 5 stars but then I started to notice the odor. They say it can hold the litter of 1 cat for 2 weeks, but at less than that I opened the container to find the litter growing mold and everything was damp inside & had condensation. Their litter container has a soft plastic bucket within the outer hard plastic container to hold the bag, and the odor has absorbed into the plastic bucket. No matter what I do I cannot get rid of this odor, and anyone that comes in the house can smell it.
I missed the 30 day return because it was given to me as a gift (ordered prior to my birthday) but I emailed ModKat with my issue anyway. I said they should consider having a longer return window & something is not right with their product. I didn’t get a reply but out of the blue we were refunded for the entire order. I’d give their customer service 5 stars this time. It’s really a shame because I liked most of their design of the Litter Keeper, but I cannot use them at all because of the poop odor in the plastic. It’s really atrocious. I’ve had the interior buckets sitting outside for a week now (in the sun when we have it) and there is no odor in the house now. But you can walk past these buckets on the porch and still smell them. I am determined to find some way to repurpose these so I am not throwing away so much plastic.
Interesting – thank you for sharing. I am glad you are happy with the litter boxes – and yes, my FAVORITE litter scoop is the Litter Lifter.
Hi! I don’t see a picture with the high sided diy with door though. Very interested in what that looked like and how it was done.
I have a “talented” tall cat and a shorter squatter lol so the door is something I would love to add to our diy box
Sorry, Kim – that’s on this page – How to Make a High Sided Litter Box – DIY High Sided Litter Box
Thanks for sharing such an informative article. I really appreciate it. My long-legged high peeing friend has started peeing out the front of the DIY box we created. I’m going to try another box and not cut an entrance into it. One question, do your Mom’s cats have no problem jumping into the box. Both our cats are healthy ten-year-olds but will eventually become a problem too? BTW we have two boxes.
My parents’ cats are now passed – but no, they never had a problem jumping in and out – as they aged, mom got lower boxes. And they would step up into them and step out of them. You might look into creating one with the door – as they could do that at any age. My dad and I experienced making one with a door. And I might still pursue it.
Thanks! Sorry to hear that. We tried one with a door and they both refused to go in. They are really something. We’ll keep trying until we get it right. 🙂
Try cutting a hole on the long side of your container instead of the short side. This will prompt kitty to turn length ways, preventing them from peeing through the opening. Not a single box with the opening on the short side has helped my situation…but on the long side victory became mine!
I have used the Kat Kave for years. I tried the NVRMiss, but with two large Ragdolls, the Kat Kave gives them more room to move around and even my stand-up peeing Ragdoll never got near the top of these.
Yes, the Kat Kave is great, if they will enter, turn around and pee – my parents’ cats entered and then peed, so it just shot out the hole.
I had trouble with my rescue, TT, because he is so long legged and tall that nothing was high enough. I finally resorted to taping a rectangle of thin plastic sheeting to the wall so that it hung down into the box by an inch. Easy to dispose of and replace when I change out the box. Fortunately he always pees toward the back side (wall) side of the box!
We have the Iris one, and there is one problem, and that is that the top bit fits over the bottom with its edges going over the outside of the bottom part. This results in the urine running down the side and finding its way through the join down the outside. Theres less urine on the floor than without it, but it’s not foolproof. Hence why I’m here, to find a solution, think I’m going to use a storage solution, no joins, no leaks!
Thank you for reporting back about how the Iris hasn’t worked for you. There is this one from Chewy that people are using for a Litter Box for High Sprayers, it might work? We are going to be adding it to this post soon.
