A lot of cats prefer to stay in private while doing their business. In that case, an enclosed litter box that also cleans itself automatically might be everything you’re looking for. (1)

The plastic hood isn’t only great for your cat’s privacy, but it also helps in keeping the waste out of sight. 

You can set the cleaning cycle to start 5, 10, or 15 minutes after your cat is finished. It works automatically, thanks to the sensor that detects that your cat has left the box.

This litter box is also great for tracking and monitoring the health of your cat’s digestive system. With its smart sensors and counters, it can tell you the number of times your cat uses the box.

Also available from Petsafe here.

  • Hooded for added privacy and blocking the odor

Next up we have a highly affordable litter box that offers peace of mind while staying efficient and packing a lot of valuable features.

The Roll n Clean litter box from Omega Paw is one of the few litter boxes that cleans itself without using electricity. Instead, it depends on rolling.

Simply, roll the litter box to turn it upside down. After that, please return it to its original upright position. 

By doing this, you activate a screen that effectively collects all the wet and clumped wastes and automatically transfers them into the scoop. On the other hand, the clean litter doesn’t stick to it and returns back to the litter box.

Once the scoop is filled with your cat’s poopers, you can remove the tray and eliminate all the waste in no time.

This smart idea is great for households on an energy budget. It gives you all the perks of an electronic litter box without adding a dime to your bills.

In addition to saving on electricity bills, it also uses much less litter than many litter boxes in the market. The efficient patented screen gets rid of clumped litter only, saving you a lot of money spent on litter bag refills.

What We Like

  • Doesn’t waste the clean litter
  • Saves a lot on electricity bills
  • Large sizes that fit houses with multiple large cats
  • Easy and less frequent cleanups

What We Don’t Like

  • Doesn’t hold a lot of silica litter and requires frequent refilling
  • No carbon filters

This one is great for houses with multiple cats, as it cleans itself in seconds. This allows it to be ready for a new patch in less than a single minute, all without scooping!

PetSafe lines the tray with plastic to prevent it from leaking its content, so you won’t have to worry about that.

Moreover, the silica crystal litter ensures that no smell will leak out of the box. It absorbs urine and dehydrates solid wastes for an unmatched level of odor control.

Despite being great at absorbing bad smells, the silica crystals are 99% free of debris and dust. This reduces their stickiness and tracking. (2) Also, it helps in keeping the litter inside the box when your cat leaves, preventing messy floors with the litter bits.

Additionally, it makes the cleanup process much easier and less frequent. You can leave it for weeks before you need to replace the tray.

What We Like

  • Non-tracking silica to reduce floor mess
  • Available in multiple colors to choose from
  • High-quality silica crystal for efficient odor prevention

What We Don’t Like

  • Doesn’t come with an adjustable rake delay
  • Lacks a health counter
  • Loose litter

If you’re looking for nothing but the best no matter what the price is, CatGenie’s automatic litter box is your way to go.

The CatGenie litter box is one of the few litter boxes in the market that flushes the waste down the drain or toilet. This means that, unlike any other item on the list, it requires no human interaction at all!

The automatic litter box works in 3 stages. First, the machine scoops all the solids and liquefies them, so it can get rid of these solids through a drain. 

After that, it fills the box with water and sanitizing solutions to purify the litter granules. Lastly, it uses heat to speed up the process of drying these granules, so they’re ready for use again.

All you need to do is connect it to the toilet in the bathroom or the drain in the laundry room and wave the tedious task of scooping goodbye! Additionally, if your cat prefers an enclosed litter box, you only need to add the GenieDome to it.

What We Like

  • Requires no human interaction
  • Easily programmable
  • Large enough to fit the biggest cats

What We Don’t Like

  • Luxurious price tag
  • No weight sensor

Simply when your cat is done, all you need to do is lift the sifting pan. It’ll automatically separate the waste clumps from the clean litter.

At the end of the day, you’ll only do the same thing you need to do with most electronic litter boxes in the market. All that comes at a price that is as affordable as a regular litter box.

One of the best things about this litter box is its size. The automatic litter box comes in a free-size pan, which is spacious enough to take the biggest of cats. This makes it excellent for your feline friend no matter how chubby it is!

Moreover, the bottom of the litter box is reinforced to support the heavyweight without breaking or collapsing.

What We Like

  • Excellent for buyers on a budget
  • Supports heavyweight cats
  • The Built-in antimicrobial protection reduces bad odor 

What We Don’t Like

  • The sifting pan might miss the tiny clumps

Things to Look for in an Automatic Litter Box for Larger Cats

While shopping for an automatic litter box for your big cat, there are multiple aspects that you need to know. These points shape your choice and make it easier to pick your ideal product according to your preferences.


Whether you need it for a big or a small cat, size does matter! Although our feline friends love to tuck themselves in the tightest spaces, they want the opposite while doing their business.

Cats are very wary about their comfort and won’t use the litter box if they can’t find enough space in it to move and breathe. That’s why it’s important to pick a litter box that’s twice as big as your biggest cat in the house.

This way, you can make sure that all your cats will find enough space to use the box without taking up much room where you’ll be placing the litter box.


Another thing that cats take seriously is their privacy. So, does that mean that all cats love hooded litter boxes? Unfortunately, cats just don’t work this way.

Every cat has its unique personality. Some prefer enclosed litter boxes and some prefer open-air ones. If you already know your cat’s preference, then you’re good to go.

However, if you don’t know, make sure that you ask your cat’s vet about what’s better for your little ball of fur.

In some cases, cats just don’t care if it’s enclosed or not. In that case, it’s better to opt for the enclosed model, as they add the extra perk of hiding your cat’s waste out of your sight and possibly the smell too.


The factor of automation makes the self-cleaning litter boxes somewhat noisy. It’s one of the few downsides of automatic litter boxes. Luckily most of the products on our list don’t produce loud noises.

As you already know, cats like to walk on the beat of their drums. If your feline friend isn’t a fan of loud noises, they might abandon the automatic litter box. 

That’s why it’s important to keep the quietness factor in mind if your cat prefers a peaceful environment.

Odor Blocking

While blocking the smell is mainly a job for the litter crystals, the design of the litter box may contribute to it as well.

As you now know, an enclosed design can help in masking the odor. You should always look for an automatic litter box that keeps the clumped litter secure. This prevents the smell from leaking out.

Ease of Use

You’re most likely buying an automatic litter box because you prefer to stay as far from your cat’s waste as possible.

In other words, having an automatic litter box that’s too complex to use or lets you do all the leg work is no use.

The automatic litter box must have a clear mechanism of action that suits you. Also, the design needs to prevent any leaking litter, so you won’t have to do extra cleanup steps.

Moreover, check the design of the litter box to make sure that it comes with an easily detachable litter tray. This way, you can get rid of its content in minutes once it’s filled with waste.


Where is the best spot to place a litter box?

As a rule of thumb, cats don’t like to have litter boxes close to their food or water. Additionally, you need to make sure that you place the box in a clean area that doesn’t have a lot of house traffic.

You should also give your cat a wide view of the room, which is easily achieved if you place the box in a corner. This way, the cat will feel the safest and will be more comfortable while using the box.

In the case of an electric litter box, you should also pay attention to the length of its electric cord and the position of the closest power outlet.

How often to replace the litter in the box?

It depends heavily on many factors, including:

  • The size of the box
  • The amount of litter it holds and its efficiency
  • The type of litter you’re using

Ideally, most brands in the market recommend that you change the litter every two weeks. Check your litter bag and the litter box manual for more information about your case.

What are the pros and cons of an automatic litter box?

Automatic litter boxes have their ups and downs. Let’s have a quick look at the pros and cons of a self-cleaning litter box.
