Key Points

  • Litter boxes are extremely important to our cats, their instincts, and their cleanliness.
  • High-sided litter boxes can help keep your space clean by containing litter and waste.
  • Look for high-sided litter boxes that are simple to clean and easy for your cat to access.

If you are a cat owner, chances are you know the challenge of keeping your litter box clean. While it would be great to have a designated space or room for this necessary chore, most pet parents have to create a small area for their cat to do their business. Having a high-sided litter box can help keep the mess and the waste contained in the box and off of your floor and walls.

Cats cover their waste in the litter box to keep it clean. While litter everywhere doesn’t make us pet owners think of cleanliness, it is actually one of the most important things to our cats. Covering their waste with litter keeps it from smelling, a way that their wild ancestors kept out of the reach of predators who may have wanted to track their scent.

Some cats are particularly enthusiastic when it comes to going number one or number two. These cats can get little in the most unlikely places, even when provided a sizable litter box and a mat to wipe their paws. A litter box with high sides can make sure that any litter that does get swatted around as they cover their waste stays in the box where it is supposed to be.

In our review, the best high-sided litter box is Nature’s Miracle High-Sided Litter Box. This litter box is simple, affordable, and provides the high-sided coverage that cat owners love. Almost all cats will happily use this litter box, even those who are very picky about their environment. The sides extend up 11 inches with an opening on one side to make it easy for cats to climb in and out. Because the sides are so high, it is unlikely that cats will jump over the sides when the entrance is so convenient. This reduces the potential for litter to scatter all over the floor, especially when you use a litter trapping mat as well.

This is a simple litter box that doesn’t have any extra features. If you want something that is covered or designed to look nice in your home, this utilitarian option may not be the right one for you. For most pet owners whose top priority is keeping their cat’s litter area clean, it is the perfect solution. The interior is non-stick and can be spot cleaned as needed.

Many reviewers liked that the box is one continuous piece. “No grooves and the corners are rounded,” said one. “This means you get a nice, smooth scooping experience. I HATE when litter gets stuck in the dips and grooves of other litter boxes.” This can also make it easier to empty and deep clean when needed.

#2 Best Self-Cleaning: Litter-Robot Self-Cleaning Litter Box Bundle

Believe it or not, there are actually multiple self-cleaning litter box options on the market. These are almost always the most expensive out of all of the litter boxes available. But if you want to take this chore off your to-do list, these robots can’t be beaten. The Litter-Robot bundle comes with everything that you and your cat need to start using a self-cleaning box. It includes the litter box, a litter trapping mat, a fence for the box, a ramp for your cat to get into the box, bin liners, and carbon filters.

The litter box sifts through what is left in the box, which is covered, to remove the waste. All you need to do is periodically empty the waste bin. The carbon filters are a nice addition to help neutralize any odors that may start to form. A wifi app can help you monitor how full the waste bin is, as well as allow you to manually start a cleaning cycle.

This is an expensive option for a litter box and not all cats like it. If you want to give it a try, just make sure you are okay with spending almost $700 on a litter box that you might have to give away to another pet parent if your cat decides it’s not for them. Reviewers who did decide to return it had to pay a return fee to get it picked up.

#3 Best Covered Litter Box: IRIS Top Entry Litter Box

This high-sided litter box makes it almost impossible for your cat to spray extra litter around the room. The only opening is a top entry point. Cats jump up to the top, something they love, then step into the enclosed litter box. Once they are done doing their business and covering it, they jump or step out. The grooves on the top of the box help clean their paws of extra litter before they jump down and resume their day.

The IRIS top entry litter box comes in a variety of colors and includes a coordinating litter scoop. The scoop can be stored on the side of the box, making it extra convenient for cleaning. If you have a particularly large cat, they may have some trouble getting through the opening. It measures 10.5 inches by 9 inches. Both the entry space and the box itself are oval-shaped.

The sleek style of the box makes it popular with cat owners. “It doesn’t look or feel like a litter box, just more like a high-end trash can or office tote. You can’t tell you’re looking at a litter box at all until you get right up to it,” said one reviewer. “Even though it’s not closed off completely, it still does a much better job of holding in odors than an open box.”

#4 Best Corner Litter Box: Nature’s Miracle Hooded Corner Litter Box

When we saw that our #1 pick from Nature’s Miracle also had a corner litter box option, we hoped it would be just as great. Fortunately, reviewers raved about this specialty-shaped option just as much. It has the same high sides at 11 inches and is triangular for the perfect corner setup. They do have an option that is sold without the top. But for just a few dollars more, we recommend opting for the hooded box so that you have that option in the future. If you or your cat decide that you prefer it uncovered, just remove the hood.

The hood does have a ventilation portion on the top and comes with a charcoal filter. This can help keep litter box odors at bay. Having a corner litter box can be harder to clean, especially when scattered litter gets into the corner behind the box. Having a high-sided litter box with a hood is the best way to keep this area clean.

If you’re a cat owner living in a small house or apartment, you know just how hard it can be to find a good place to put the litter box. Fortunately, with a clever design, the Litter Genie makes it a little easier for those with small spaces to find the right spot. The flexible plastic material means you can maneuver this litter box into narrow areas that many other bulky boxes would never fit into—it even fits under many bathroom sinks and in cabinets.

While there is no hood, the high sides mean the littler will stay in the box. The smooth construction means it is incredibly easy to clean as you won’t need to worry about litter getting stuck in grooves.

Choosing the Best: What to Look For

High-sided litter boxes can come in a variety of sizes, shapes, and with extra features that make them easier to use or clean. Here are the things that you should consider and look for when picking a high-sided litter box for your cat.

Size

While they may not be as vocal about their preferences as dogs, cats are actually quite picky when it comes to their litter box setup. You should make sure that the box is large enough for your pet to use comfortably and that it can hold your pet’s waste without getting full for at least a day. If you have multiple cats, consider getting an extra-large litter box or multiple standard-sized litter boxes. This will keep them happy and your home cleaner.

Shape

Most litter boxes come in a rectangle but there are also other shapes that may work better for your available space or your cat’s preferences. Litter boxes designed for the corner can be a great option and are usually triangle-shaped. The biggest determining factor when deciding which is best for you is the placement in your room. If you want to put the litter box in the corner, having a box designed for this is the best use of the space.

Circular or oval litter boxes are less common but can be a good choice for cats who tend to scratch or dig at the corners of square or rectangular boxes. Because there are more places for litter to scatter outside of the box, especially when placed in a corner or against a wall, opting for a circular or oval-shaped box may result in more cleaning for you. These litter boxes are more likely to have a cover to help prevent this issue.

Special Features

Covered tops, self-cleaning, special entryways–who knew there were so many cool features that a cat litter box could have? These boxes are often more expensive but can be well worth the higher cost with the convenience that they bring to your life. Look for something that suits your needs and that your cat likes. Some cats dislike a covered litter box. Give them some time to adjust to this new setup.

The Different Types of High-Sided Litter Boxes: Pros and Cons Compared

When choosing the best high-sided litter box for your cat and home, you will most likely need to decide between a covered option and an uncovered option. Consider your cat’s preferences and the pros and cons listed here.

Covered litter box: Can keep the litter more contained. May be harder for large cats to get in and out, as well as for you to clean. Many have a removable cover so you can always convert it to an uncovered option.

Uncovered litter box: Open top makes it easy for the cat to use and for you to clean. Simple to pour fresh litter into the box. Some cats spray litter around the room more when using an uncovered box.

Our Criteria and Experience, How We Chose the Best

As a long-time cat owner, I know exactly how messy litter boxes can be. Whether cats are big diggers and sprayers or the box is simply too small, it doesn’t take much for litter to end up absolutely everywhere. High-sides can help solve a lot of these problems, creating a barrier to keep waste and litter contained and keeping the area around the box cleaner for longer.

Different cats have their own preferences and plenty will refuse to use boxes that are totally covered, with top entry, or with closing doors. But high-sides alone usually won’t intimidate a cat or discourage them from using the box, making it an easy transition for both you and your furry friend.

In addition to high sides, boxes that are easy to clean are a must. And litter boxes that look nice or can fit into discrete areas are a nice bonus, especially if you live in a smaller home.
