Guide To Choosing The Best Litter Box For Multiple Cats

Choosing the right litter box for multiple cats is much harder than finding a perfect litter box for just one kitty, simply because you need to find one that fits them all. You need to take into account potential differences in age, size, and preferences and get a litter box that can successfully deal with more waste and more odors.

To help you pick the best litter box for multiple cats that cohabitate in your household, we have assembled a list of factors you need to keep in mind when making your decision.

Accommodation Capacity

Litter boxes for multiple cats differ in terms of the number of kitties they can service. While some only work for 2 cats, others come with no specific limitations regarding accommodation capacity.

Litter boxes with unlimited capacity are usually much bulkier, so if you only have 2 cats and little free space in your home, a 2-cat litter box is a better choice.

It should also be noted that if you live with more than 3 cats, you should consider getting more than 1 multi-cat litter box because litter gets exhausted rather quickly when a larger number of cats use the same litter box. Plus, it is easier to clean 2 litter boxes every couple of days than deal with smelly waste every single day.

When it comes to litter boxes for multiple cats, size really does matter. First of all, not all cats are the same size. If the litter box is more spacious, it can work fine for both the large and the small cats in your home. Second, a larger cat area provides more space for litter. This is highly important due to all the digging and liquid waste that needs to be soaked in.

Third, even though cats rarely go to the toilet together, some may express this preference, especially if they are kittens, so you may want to give them enough room to do their business simultaneously.

Ease Of Entry

Some cats are agile and do not mind jumping and climbing. Others may have difficulties getting into top-entry litter boxes or boxes with sides that are too high to climb. Kittens, small cats, elderly cats, and disabled kitties require a side-entry litter box with low sides or a ramp, which lets them use the toilet with ease. Thus, it is best to choose a litter box that is easy to get in and out of, even if most of your cats are in their prime.

Two cat kitten brethren sleeping


With 3 or more cats using 1 litter box, frequent cleaning is more than necessary. Cats like clean toilets and if the litter box has not been cleaned since previous use, they may choose to do their business elsewhere.

Therefore, it is best to opt for a self-cleaning litter box that can keep the litter clean at all times, without your assistance. That way, you do not have to worry about improper elimination due to the presence of other kitties’ excrement in the litter box.

If you have no more than 2 cats, a traditional litter box can be a good choice, but it has to allow for easy scooping, making waste removal less time-consuming. It should also be made up of as few elements as possible, preferably with no crevices, so you do not have to invest too much effort into maintenance.

Waste Disposal

This is particularly important if you opt for a self-cleaning litter box. Most automatic litter boxes for multiple cats feature large waste receptacles, allowing for less frequent waste disposal. However, they still differ in waste capacity. Obviously, bigger is always better. With some of the best self-cleaning litter boxes for multiple cats, the waste drawer is so big you only need to empty it about once a week if 2 cats are using the litter box or once every couple of days with 3 or more cats.

It is also important to pay attention to the ease of waste disposal. Since you are bound to do it often, it is best to opt for a litter box with a waste receptacle that is easy to remove and can be lined with regular garbage bags, so you can just take out the bag and be done with it.

Some self-cleaning litter boxes for multiple cats even dispose of waste on their own. If you are incredibly busy, that’s definitely the kind of litter box you want in your home.

Odor Control

Good odor control is always a plus, but with litter boxes for multiple cats, it is an absolute necessity due to the increased amount of waste. You should pay attention to everything from the kind of litter the litter box uses (absorbent or not) to the presence of a waste receptacle cover and carbon filters that can prevent the odors from spreading across the room. Other bonuses include anti-microbial surfaces and moisture pads that can prevent the growth of microorganisms and lock in the smell of liquid waste.


Not all cats are gentle on their litter boxes and they may like to climb on top of them, scratch the surface or play with dangling elements. If more than one cat uses the litter box, the chance of damage is significantly increased. Thus, when choosing the best litter box for multiple cats, you want to get one that is made of high-quality materials and features a sturdy construction, so it can last for years to come.

Cat Safety

Cats are cautious but also curious. If there are some electronic components within their reach, they may want to inspect and play with those strange parts. They may nibble on elements they should stay away from, such as wires and cables. They may jump into the litter box without noticing a sharp edge.

Thus, be sure to choose a litter box that is designed with safety in mind, without any exposed electronic components or protruding elements that may harm your kitties. It is also crucial to make sure that the litter box is made of non-toxic, pet-safe materials, so your cats’ health is not in danger even if they decide to lick the litter box.


Some cats are timider than others. Some are extroverted, others are introverted. There are kitties that enjoy trying out new things and there are those that like to stick to what they know and love. However, there are some litter box features that all cats appreciate. If you want to get a litter box for multiple cats that can keep all of your feline friends happy, you need to get one that is cozy, inviting, spacious, comfy, quiet, and not too claustrophobic. In other words, you need a cat-friendly litter box that makes for a perfectly pleasant and appealing toilet, regardless of individual preferences.

A litter box for multiple cats is supposed to help you save cash you would otherwise spend on additional litter boxes, extra litter, and other necessities. Thus, although it makes sense for a multi-cat litter box to cost a bit more than a litter box that is designed to service only 1 cat, you should make sure that the litter box of your choice is actually cost-efficient.

You want to get one with a lengthy warranty that proves it is built to last. You want your cats’ litter box to use less litter than a conventional litter box, so you do not have to go litter shopping all the time. It is also important to make sure that the litter box you opt for does not require plenty of expensive accessories, which is the case with some litter boxes for multiple cats.

Finally, you should know that multi-cat litter boxes do not have to be significantly more expensive than their single-cat counterparts. Thus, you only want to spend more money if the litter box in question is obviously superior to its competitors in virtually all aspects.

Our #1 pick

Litter Robot

The Most Advanced Self-Cleaning Litter Box
Our Rating: 9.8/10

Litter Robot product

Litter Robot is probably the most advanced self-cleaning litter box for multiple cats. Everything from its spacious cat chamber to its patented litter-sifting system and great odor control makes it an optimal choice for multi-cat households. Plus, there are no limitations on the number of cats that can use it, although up to 3 cats is optimal.

To make sure every cat has a clean box to use at all times, this litter box automatically removes waste 3, 7 or 15 minutes after use, depending on the settings you choose. Its cleaning cycle is quiet and short, lasting just about 2.5 minutes. During the cycle, the cat chamber rotates slowly, separating clean litter from waste via a mesh screen and dumping the waste into the waste drawer through a special chute. At the end of the cycle, the chamber returns to its original position and evens out the litter bed, leaving it completely clean and dry.

Litter Robot’s cat area is spacious and comfortable and can accommodate cats weighing 5 or more pounds. It can be used by small kittens, but only if the cleaning cycles are started manually because the device uses weight-activated sensors that detect cat movement and prevent the chamber from rotating with a cat inside. The waste drawer is large and it only needs to be emptied every 5 days with 2 cats and every 2-3 days with 3 cats.

The most important features of Litter Robot include fully automated scooping, patented litter-sifting system, cat motion sensors, adjustable timer, sleep mode, low noise levels, closed waste drawer and large carbon filter for optimal odor control, full-drawer indicator, nightlight, backup battery, step mat for minimized tracking, durable construction, and pet-safe materials.

Litter Robot can work with any high-quality clumping clay litter and it does not require any special liners, so you can use regular garbage bags for easier waste disposal. Litter Robot comes with a 90-day money-back guarantee and an 18-month full warranty.

PetSafe Simply Clean

Super Quiet Self-Cleaning Litter Box
Our Rating: 8.1/10

PetSafe Simply Clean homepage

PetSafe Simply Clean is one of the most affordable self-cleaning litter boxes for multiple cats. Its main distinctive feature is that it works round the clock, keeping the litter area clean at all times, which is the best way to avoid improper elimination in a multi-cat household with a single litter box. For more good news, there is no limit on the number of feline users.

The litter box rotates constantly, sifting the litter and transporting the waste into a covered waste receptacle. Constant rotation may sound like something your cats may not like, but the fact is that the movement is so slow it is unnoticeable. The circular cat area completes a full circle in an hour and it is quiet enough not to scare even the timidest of cats.

The crucial features of PetSafe Simply Clean include fully automated cleaning cycle, easy setup and use, good odor control with the closed waste receptacle, easy litter disposal, low litter consumption, quiet operation, and low electricity consumption.

While PetSafe Simply Clean is comfy and easy to enter, it is not suitable for all cats, as its cat area can only accommodate cats weighing no more than 15 pounds.

PetSafe Simply Clean can work with any kind of hard-clumping litter. If you want to dispose of waste more easily, you can line the waste receptacle with a regular garbage bag. You can use any brand of cat litter, as long as it clumps. Other types might clog the mechanism and result in the device malfunctioning. The waste receptacle can be used on its own, but you can also line it with a regular plastic bag for easier waste disposal.

PetSafe Simply Clean is extremely budget-friendly and comes with a 45-day money-back guarantee and a limited non-transferable 1-year warranty.
