5 Best Self Cleaning Litter Boxes: For Multiple Cats (In 2021)

Ok, so let's face it ...we ALL hate cleaning out kitty litter trays

I personally hate the process of scooping out all the stinky wet litter on that dreaded day of the week ..."litter tray cleaning day".

Guess what? You can make life easier by automating the waste disposal process.

How, you may ask?

A self-cleaning litter box can make your life a little easier with no more need to manually sift through your cat’s toilet daily. These litter boxes make waste disposal easy by automatically cleaning and disposing of your furry friend’s little deposits, also helping to reduce household odors.

How do Automatic Litter Trays Work?

They are designed to detect cat movements (no - not that type of movement!), so that once your cat has finished their business they automatically remove solids, and deposit the waste in a waste compartment.

This helps to prevent unpleasant sights and smells from spoiling your relationship with your cute feline companion.

There are many different designs available and they all aim to remove solids from the litter. Many designs allow you to easily dispose of the used litter via a disposable tray or bag.

  • Most designs have a rake system that drags through the litter and catches the solids, and there are a variety of ways that the machine then deals with the waste. There is even one design that automatically washes and dries the litter!

One common thing with this type of litterbox is that you will need a power source for them to operate.

Choosing the Best Self Cleaning Litter Box

Before opening your wallet to buy an automatic cat litter box, you should consider various factors that will make it easier for you and your cat to use the box.

From the different brands, varieties, and functionalities of various litter boxes you should choose a litter box that your cat will most likely be comfortable with.

Here are some of factors to consider:

Size Matters

The first question you should ask yourself is: How much space will the litter box need?

If you reside in an apartment, you might go with a small-sized box that fits in your available space. If your cat is big or you have multiple cats, go with an automatic litter box that is big enough to accommodate their needs.

Number of Cats

How many cats do you have? Will they fit in one litter box or will you need two boxes? Some litter box brands can accommodate two to three cats at once, typically ones with a large waste storage capacity.

However, if you have more than three cats, you may purchase two or more litter boxes that your cat can use comfortably.

Cat Preferences

What happens if you buy something that the cat does not like? Take into account your cats preferences and habits when buying an automatic litter box. For cats that love closed space, go with a litter box that includes an enclosed hood.

Ease of Use

Automatic litter boxes still need a certain amount of human intervention to keep them operating, look for a box that minimizes the waste disposal and cleaning headaches.

Another function offering ease of use is to have a wifi-enabled unit that lets you operate and regulate the functions easily. An ideal choice for a litter box is one that allows you to dispose of waste effortlessly, and excels in odor control.

Power Sources

Some automatic cat litter boxes require an electrical power source for it to function.

 Obviously you will need to install or place the litter box near electrical outlets for easy installation, or otherwise consider the cost if you need an electrician to install an extra outlet.

If sourcing power is an issue or too expensive, look at a battery operated unit.

Should you Buy a Self Cleaning cat Litter Box?

If you're like me, you would prefer spending more time bonding with your fluffy feline friend instead of dealing with their kitty litter issues.

Automating cat waste disposal becomes almost effortless with an automatic cat litter box. Here are some of the benefits that you get by automating litter disposal:

Time saving 

Don’t have time to scoop the litter? Just get yourself the best automatic litter box and let it do the work while you take time to do more important things (like pat you cat of course!).

Your effort will only be needed when throwing out the bag of litter or changing the disposable tray once every few weeks. Far better than the daily chore with an ordinary litter box.

Hygiene

An automatic cat litter box is not only more hygienic for your cat, but also for you! With odorless litter boxes and non-clumping litter, you won't have to worry about unpleasant smells getting into the house.

Cats are super-sensitive to foul smells, and living in a hygienic environment is far preferable for your cute companion.

With automatic cleaning, no urine or poop will be left soaked in the litter box, and even better your cats paws won't be digging in dirty litter after each use of the box.

Luxury

Just like us mere humans, cats like demand to be pampered once in a while! After all, it's not much to ask - especially since we exist purely to meet their needs. Cats just need food, love, shelter and good clean place to do their business.

An automatic cat litter box provides not only a fresh-smelling environment but also an odor-free room. There's a reason why people like bidet's, and for that exact same reason your cat will be in a happier place with the feline equivalent.
