    The 10 Best Litter Boxes for Multiple Cats — Reviews & Top Picks 2021

    1. Frisco Multi-Function Covered Cat Litter Box — Best Overall

    Frisco Multi-Function Litter Box

    Entry Style: Side
    Size: 73” x 17.5” x 17.64”

    If you’re looking for the best overall litter box for multiple cats, this is it. It’s a large litter box, but that’s perfect for multi-cat homes. It comes with plenty of storage space to hold everything that you need.

    From the litter scoop to deodorizers and litter, with this Frisco litter box, there’s room for everything. But it’s not just about storage; it also has a flip-up design that makes clean-up easy, and the covered lid helps with both diggers and sprayers.

    While this might be one of the best litter boxes out there, it is slightly expensive, and you need to have enough space for it. If you have the space and the money, though, having everything in one spot makes litter-box duty so much easier.

    Pros
    • It has storage space
    • Litter scoop holder
    • Flip-up design makes clean-up easy
    • Covered lid contains the mess
    • Large size is customizable
    Cons
    • Large size makes it hard to fit in tight spaces
    • Slightly more expensive

    2. Frisco High Sided Cat Litter Box — Best Value

    Frisco High Sided Cat Litter Box

    Entry Style: Open top/Pan
    Size: 24” x 18” x 10”

    Just because you don’t want to spend a ton of money doesn’t mean you can’t get a great litter box for your cat. The Frisco High Sided Cat Litter Box is one of the best litter boxes for multiple cats for the money, and it’s not hard to see why.

    Not only is it inexpensive, but Frisco made it from BPA-free and recyclable plastic, which makes it good for both your bank account and the planet. Moreover, it’s easy to clean and easy for your cat to enter, making it an outstanding choice for older or disabled cats.

    Furthermore, it comes in two different colors, and while neither is the most stylish option out there, it can match the room a bit more.

    However, the lower price has a few tradeoffs. For starters, while it has high sides, cat owners of sprayers and diggers know that an open-top design like this isn’t enough. Moreover, it has no odor control, and you can always see the litter.

    But for a budget litter box, it’s a great option.

    Pros
    • Affordable
    • BPA free and recyclable
    • Easy to clean
    • Easy to enter
    • Two-color options
    Cons
    • Can send litter flying
    • Does not do a good job at eliminating odors
    • Does not hide the litter

    3. Whisker Litter-Robot — Premium Choice

    Whisker Litter-Robot automatic cat litter box

    Entry Style: Front-covered top
    Size: 25” x 27” x 29.5”

    If you’re looking to buy the last litter box that you’ll ever need and want to make your life a little easier, you need to check out what the Whisker Litter-Robot has to offer.

    First, it’s completely self-cleaning. The weight-activated system starts the cleaning process after each use, and you never need to check when you need to change the litter box. Instead, it hooks up to your home’s Wi-Fi and will shoot updates straight to your phone to let you know when it’s time to change the litter!

    Also, clean-up is a breeze. All you need to do is pull out the tray and throw away the waste! The waste drawer is carbon-filtered, so the odor is never a problem. A single unit can support up to four cats, and there are two color options to choose from.

    It’s expensive, but if you can afford it, it’s worth every penny.

    Pros
    • Self-cleaning design
    • Wi-Fi enabled and comes with app
    • Two-color options
    • Carbon-filtered waste drawer helps eliminate the smell
    • Supports up to four cats
    Cons
    • Expensive

    4. Litter Spinner Cat Litter Box — Best for Kittens

    Litter Spinner Litter Box

    Entry Style: Front
    Size: 5” x 18.5” x 10.5”

    One problem that gets overlooked with many litter boxes is how a smaller kitten can get in and out. That’s not a problem with the Litter Spinner. While it can only support cats up to 10 pounds, that’s perfect for both kittens and smaller cats.

    While it’s a little expensive, it also has a hands-free easy-to-clean design that doesn’t require any batteries or power cords. Simply spinning the container sifts out the waste and leaves you with a clean litter box!

    It also has dust-controlling and odor-controlling features that are a huge perk. If there’s one thing that we wish we could change, it’s that cats can still kick litter right out the front.

    Pros
    • Easy-to-clean design
    • No power cord or batteries
    • Reduces odors and dust
    Cons
    • Slightly expensive
    • Only works with smaller cats (under 10 pounds)
    • Cats can kick litter out

    5. Nature’s Miracle Multi-Cat Automatic Self-Cleaning Cat Litter Box

    Nature's Miracle Auto Cat Litter

    Entry Style: Open top/Pan
    Size: 11” x 28.25” x 19.5”

    If you’re looking for a self-cleaning litter box but are on a budget, the Nature’s Miracle Multi-Cat Automatic Self-Cleaning Cat Litter Box is ideal. This isn’t a low-priced litter box, but for an automatic-cleaning one, it has an outstanding price. It uses a motion-detection system to clean after each use, and it has a high wall design to help prevent litter spray and digging messes.

    It also comes with a paw cleaning pad at the entrance to help keep your cat from spreading litter as they exit, and it has a night light for easy visibility after everyone’s gone to bed.

    However, the open front is an area where cats can launch litter, and the overall box is a bit small if you have large cats.

    Pros
    • Self-cleaning litter box
    • High wall design helps prevent litter spray
    • Paw cleaning pad at the entrance
    • Night light for easy visibility
    • Carbon filters help control the odor
    Cons
    • Open front can launch litter
    • More expensive option

    6. IRIS Top Entry Cat Litter Box

    IRIS Top Entry Cat Litter Box with scoop

    Entry Style: Top
    Size: 32” x 13.39” x 12.2” OR 20.47” x 16.14” x 14.56”

    If you have dogs in the home, it’s time to check out top-entry litter boxes. The beauty of these is that healthy cats can get in and out, but your dog can’t get their head in far enough to eat the cat droppings.

    When it comes to top-entry litter boxes, the option that IRIS makes is a good one. There are four different color options and two different sizes available, so there’s a good chance that there will be an option that you like.

    Additionally, the lid has grooves to help clean paws, and it comes with a matching litter scoop and hook for easy storage. However, we wish that there was an odor control feature. Also, if you have an older or disabled cat, they might not be able to navigate the top-entry system.

    Pros
    • Affordable
    • Four color options
    • Two size options
    • Grooved lid helps clean paws
    • Includes attachable hook and scoop
    • Top-entry design keeps dogs and other pets out
    Cons
    • Top-entry design can be challenging for older/disabled cats
    • No odor control features

    7. Frisco Flip Top Hooded Cat Litter Box

    Frisco Hooded Cat Litter

    Entry Style: Flip top front entry
    Size: 7” x 17.3” x 16.1”

    An extremely affordable litter box option is the Frisco Flip Top Hooded Cat Litter Box. It’s an ethically sourced litter box that Frisco made from BPA-free recycled plastic, and the flip-top design makes clean-up a breeze.

    However, the hinge design that holds the entire product together can create a problem for sprayers, and some cats simply can’t figure out how to work the front entrance door, no matter how many times you show them.

    Of course, if your cat can figure out the door but other pets in your house can’t, then it’s a great feature that keeps other pets out. Finally, this litter box uses charcoal filters to help minimize the odor, and that’s a huge perk for those living in smaller quarters or with sensitive noses.

    Pros
    • Affordable
    • Made from BPA-free recycled plastic
    • Flip-top design makes clean-up easier
    • Charcoal filter helps fight odors
    • Hooded door helps keep other pets out
    Cons
    • Hinge design can lead to leaks from sprayers
    • You might have to remove the door

    8. Frisco Leaf High-Sided Cat Litter Box

    Frisco Leaf High Sided Litter Box

    Entry Style: Front
    Size: 41” x 17.3” x 15.95”

    At first glance, this litter box might not look like much, but the longer that you look at it, the more you realize what it has to offer. For starters, the sides are more than high enough to help contain spraying and digging, as long as your cats don’t aim their efforts toward the entrance.

    It has an open-top design, with easy carrying handles and sides that turn into spouts. All this makes cleanup easy when it’s time for spot cleaning and for changing the entire litter.

    It’s a simple litter box, but it gets the job done and makes your life easier in the process. For a lower-priced litter box, that’s a pretty good deal. However, you will need to accept the fact that there’s nothing to help with odor control, and since it is an open-top design, you can see the litter the entire time.

    Pros
    • Affordable
    • Easy to carry and move
    • Cleanup is easy
    • Easy to wash
    • High side design helps with spraying
    Cons
    • Nothing to keep other pets out
    • You can see the litter at all times
    • Nothing to help with odor control

    9. Nature’s Miracle Just For Cats Advanced Hooded Corner Cat Litter Box

    Nature's Miracle Corner Litter Box

    Entry Style: Front entry
    Size: 23” x 26” x 11”

    Nature’s Miracle Just for Cats Advanced Hooded Corner Cat Litter box might be too expensive for what you get. The corner design is an excellent feature for those trying to save space, but in the end, it’s a basic litter box.

    There’s an antimicrobial coating to help prevent bacterial growth, and the nonstick surface makes cleanup easier, but if you’re keeping up with proper cleanings every other day, these aren’t major concerns.

    The nicest perk to this litter box is the charcoal filter that helps keep odors at bay, but for the price, you can find nicer litter boxes that have that and more.

    Pros
    • Antimicrobial coating helps prevent bacterial growth
    • Nonstick surface makes cleanup easier
    • Charcoal filter helps with odor control
    • Corner design helps keep the box tucked away
    Cons
    • More expensive for what you get
    • No front door cover can spread litter

    10. IRIS Large Shielded Litter Pan

    Iris Large Shielded Litter Pan

    Entry Style: Open top
    Size: 68” x 15.51” x 10.63”

    The IRIS Shielded Litter Pan can get the job done if you have cats that don’t dig or spray, but if you do, expect a mess. It’s a no-frills, basic litter box.

    It’s easy to clean and includes a matching scoop, but it’s hard to find any perks past that. You can see the litter all the time, and there’s nothing to help contain the odor.

    Even at this price, you can do better.

    Pros
    • Two color options
    • Easy to clean
    • Affordably priced
    • Includes matching scoop
    Cons
    • Does not contain the mess well
    • You can see the litter at all times
    • Nothing to contain the odor

    Buyer’s Guide

    If you’re struggling to determine precisely what litter box is right for you, you’re not alone. That’s why we came up with this comprehensive buyer’s guide to walk you through everything that you need to know and help you pick out the right litter box for your cats the first time.

    Picking a Litter Box Style

    One of the most important decisions that you need to make when picking out a litter box is style. There’s no right or wrong choice here, but there are options that are better or worse for your home. We break down each style and its pros and cons here.

    Open Top/Pan

    Open-top, also known as pan style, litter boxes are the most basic options out there. They have both low- and high-sided options, and what you need depends on whether your cat digs or sprays. The most significant advantage of this style is the price.

    They’re among the least expensive options out there, and some owners do better at keeping up with cleanings if they can see the waste. Of course, the downside of these boxes is you can see the waste all the time, they’re often messier, and they typically don’t have any odor control.

    Front Entry

    Front-entry options are extremely popular because they help with cats that spray or dig. While a cat can obviously still kick litter right out the opening, having only one side where they can send out litter or urine is better than four sides.

    For some cats, they can satiate their spraying and digging needs without ever aiming for the opening. Front-entry options are easy for your cats to get in and out of, and they’re often among the more affordable options.

    Another option is side entry, but this is essentially the same design — the opening is just on the side of the litter box instead of the front.

    Top Entry

    If you have other pets, especially dogs, in the home, then you strongly need to consider a top-entry litter box. Dogs have a fascination with eating cat poop, and if they have easy access to it, it’ll be a constant back-and-forth struggle between them trying to get into the litter box and you trying to stop them.

    A top-entry litter box eliminates this struggle for all but the largest dogs. Your cats can simply hop on top and climb in, and your dog or other pets can’t get their heads inside.

    But while this is a huge perk in that regard, if you have older cats or cats that can’t jump high for whatever reason, they might struggle to get in and out of their own litter box — and that would render this litter box style all but useless.

    Door Entry

    Some litter boxes have a front-entry litter box and then have a flip-up door installed on it. This gives your cat total privacy when they’re inside, and it offers a little more protection from spraying and digging. The door opening won’t contain the entire mess, but it’s far better than nothing.

    The door also often acts as enough of a deterrent to keep other pets from nosing their way to the litter. But the tradeoff is that some cats simply don’t like using the door. If the cat won’t use the door, then you’ll have to take it off, and you basically have a front-entry litter box.

    How Often Should You Clean the Litter Box?

    No matter what litter box you choose, you’ll need to clean it. Self-cleaning litter boxes are the exception, but even then, you’ll need to empty the waste container when it gets full.

    For a traditional litter box, you should clean it at least once every other day. If you have more than two cats and only a single litter box, you should probably clean the litter box daily.

    How Many Litter Boxes Should You Have?

    If you have multiple cats in your home, it’s logical to wonder how many litter boxes you should have. The good news is that there’s a simple rule that you should follow: Get one litter box per cat, plus one more.

    So, if you have three cats in your home, you should get four litter boxes, and if you have five cats, you should get six. With some of the more expensive options out there, you can see how this could quickly get costly.

    But by getting the right number of litter boxes, you reduce the likelihood of one or more of your cats relieving themselves where they shouldn’t, and there’s less of a chance of them developing aggressive or territorial behaviors toward the litter box.
