The 5 Best Self-Cleaning Litter Boxes For Multiple Cats In 2024

Best Covered: Litter-Robot 4 Automatic​

Why We Chose This Litter Box:

The Litter-Robot 4 stands out as the highest-performing litter box on the market. They practically used the customer feedback and upgraded the Litter-Robot 3 Connect to include more advanced features and bring more solutions.

This litter box is quite smaller than the previous model. However, it has a wider opening for more comfort, a quieter cleaning cycle, and an enlarged waste drawer. They also integrated multiple advanced sensors (thermal, motion, and weight sensors) to insure a higher awareness of their surroundings and to improve their safety measures.

The manufacturer has been in the field for 20 years, and they’re quite known for investing in engineering and continuous optimization.

And that is why the Litter Robot is quite efficient at litter consumption, odor control, and, most importantly, low maintenance costs.

Best Large: Litter-Robot 3 Connect​

SPECS

This price was taken at the time of this publication.

Why We Chose This Litter Box:

Besides being eye-catching, this litter box needs quite some space and wouldn’t fit in small rooms. When the cleaning cycle starts, the globe begins to rotate in order to clean the litter bed and filter all the clumps straight to the waste compartment. You can find this process to be a bit noisy if you’re close enough to the litter box. However, it does a pretty good job compared to its competitors.

The Litter-Robot 3 Connect is quite good at controlling both litter scatter and odors (thanks to the carbon filters in the waste store) as long as you’re using high-quality clumping cat litter.

It comes with an app that helps you monitor the waste drawer while tracking your litter box’s real-time activity, even if you’re not at home.

This high performance comes at a price, obviously. It’s worth mentioning, however, that in the long term, this litter box is low maintenance and will cost less than most other automatic litter boxes that require recurring expenses (Proprietary Litter, disposable litter trays, spares, etc.)

Best Odor Control: PetSafe Scoop Free Smart Self-Cleaning Litter​ Box

ScoopFree Smart Self-Cleaning Litter Box

SPECS

This price was taken at the time of this publication.

Why We Chose This Litter Box:

This is the upgraded version of the well-known Scoop Free Original Self-Cleaning Automatic Litter Box (hyperlink: ScoopFree Self-Cleaning Litter Box, Second Generation). It can monitor your cats’ health and track their litter box activity through the “My PetSafe” app.

The cleaning cycle is actually calmer than most of the automatic litter boxes out there. The rake moves smoothly (20 minutes after your cat exits) to scoop waste clumps into the waste receptacle.

The crystal litter that comes with the Scoop-Free litter box does a great job at odor control and liquid absorption until it reaches its maximum limitation. This, along with the disposable litter tray, will need to be replaced depending on how many cats are using it, which can be quite expensive in the long term. Some users opt for a reusable plastic tray in order to save money.

Best for Small Appartments: Petree Automatic Litter Box​

Petree Automatic Self-Cleaning Cat Litter Box

SPECS

This price was taken at the time of this publication.

Why We Chose This Litter Box:

This is the best cat litter box furniture, with a design similar to the litter robot series. It has a rotating cleaning mechanism that is very quiet. Through the app, you can track your cat’s weight along with its litter box activity.

The Petree App can also alarm you when the trash bin is full. You may find it a bit troublesome to take it out and clean it since it’s located in the back of the litter box.

This litter box does a pretty good job when it comes to both odor control and scattering. It doesn’t require frequent cleaning. However, it still doesn’t offer the same level of features compared to similarly priced models such as Litter Robots.

Best Monitoring: Petkit Pura X Self-Cleaning Litter Box

PETKIT Pura X Self-Cleaning Cat Litter Box

SPECS

This price was taken at the time of this publication.

Why We Chose This Litter Box:

The Petkit PURA X is quite similar to the litter robot when it comes to its cleaning mechanism. The globe inside starts rotating to filter all the clumps inside the litter and direct them straight to the waste store.

This might be the best self-cleaning litter box when it comes to tracking the activity of multiple cats at once. The app can help you track their weight, their usage duration and frequency, monitor the waste store, control the cleaning cycle, and many other features.

This litter box has more sensors than any other automatic litter box in order to secure the cats safety. It can detect if our furry companions are inside the litter box or near it.

Although the opening is a bit small, the cats can get used to it over time. The PURA X might benefit from an entry mat that captures the litter scattered in front of it. But overall, it does a great job at containing odors.

WHAT ARE WE LOOKING FOR IN A LITTER BOX

Buyer's Guide: What Are We Looking For?

Ease of cleaning:

The cleaning mechanism of the litter box should be able to filter the litter thoroughly in order to scrape through everything. We also check that there are no gaps within the design that might lead to cake buildup or liquid leaks.

Large waste drawer:

If you have multiple cats at home, you’ll prefer a large-capacity waste drawer (5 liters or higher) so you won’t have to change it twice a week. The waste drawer should also be sealed off with a filtration system in order to have an odor control feature.

Cat-Friendliness:

The litter box should be paw-approved. The entry, in particular, must be spacious and inviting. Not to mention that there should be sufficient litter for cats to step on to make them feel at ease when using this litter box.

Quality/Reliability:

If the litter box continues to crash every time our beautiful felines use it, what is the point other than to waste countless hours and money on repairs and troubleshooting? That is why we ensure that the product has a solid reliability background through good engineering and positive customer feedback.

Reputation:

The longer a manufacturer has been in business, the better. It lends credibility to the company and reflects on the success of their products. A warranty is also something to think about, as is good customer service in case of problems with the packaging or component replacement.

Recurring payments:

Litter boxes typically have parts that need to be replaced on a regular basis. The most common ones are disposable filters and liners. Their longevity and cost can have an impact on your monthly spending over time.

FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

What size litter box for a large cat?

According to the 2022 ISFM/AAFP Cat Friendly Veterinary Environment Guidelines published in the Journal of Feline Medicine and Surgery, the litter box should be 1.5 times the length of your cat from the nose to the tip of the tail. Whereas the width should be equivalent to your cat’s length, the tail is not included. A cat that is about 18 inches long needs a litter box that measures 27” long by 18″ wide. A litter box that most likely doesn’t exist out there. That is why it is best to select the largest and nicest litter box for your beloved cats.

How deep should a cat litter be?

It is recommended that you use a maximum of 2 inches to 4 inches of litter in your litter box. If there are numerous cats using the litter box, you’ll need 3 to 4 inches of litter to absorb all that urine and clump around.

In fact, anything less than 2 inches will cause unpleasant odors to develop as well as a high probability of inappropriate elimination. On the other hand, too much litter will lead to a mess since most cats will simply kick it outside.

What type of litter box do cats prefer?

Research was conducted and published in the Journal of Feline Medicine and Surgery regarding this subject. The results showed that out of 28 different cats, 4 showed a preference for covered litter boxes and 4 for open litter boxes. The rest of the cats were happy to use any type of box they provided as long as it was well-cleaned.

This only shows that our cats have unique preferences, and only by getting to know them will we be able to fulfill their needs in the best way possible.

How often to replace cat litter?

If you have one cat at home, you’ll most likely need to change clumping cat litter every 2–3 weeks. However, if you’re using a non-clumping litter, you’ll have to change the litter completely twice a week.

How often should you clean a cat litter box?

If you have an automatic litter box, you can perform a deep cleaning once a month. Unless, of course, there is a problem of feces scattering or building up inside the litter box. You will need to clean it more often in that case.

If you have a manual litter box, the litter should be scooped and cleaned at least twice a day.

Where to put the cat litter box?

Cats love to have their cat litter boxes in a corner that is calm, private, and accessible. You’ll also need to keep food away from this spot in order to leave this space dedicated to sanitary activities.
