Best Clumping Cat Litter For Automatic Litter Boxes

What To Consider When Buying

â TOP 5 Best Automatic Litter Box [ 2022 Buyer’s Guide ]

When comparing and evaluating litter boxes, consider the following:

Scooping Time

The majority of self-cleaning litter boxes have sensors that activate cleaning a few minutes after your cat finishes its business.

However, if you want to schedule the scooping time, look for litter boxes with an adjustable timer.

Waste Bin

Some models are self-flushable, while others have a bin that you have to empty. Both systems are good. You just need to choose the one that suits your needs better.

Noise Level

According to many customers, this type of litter box can be quite noisy due to all its moving parts. This can be scary to cats and annoying for pet owners, especially if they dont turn off the box during the night.

Ease of Cleaning

Just because these litter boxes are self-cleaning doesnt mean you never have to clean them. Select a model thats easy to assemble after cleaning. Simpler models are usually easier to clean.

Litter Type

As we mentioned, different models require different litter. Choose a model that supports the litter your cat likes using, or you may end up with a litter box thats useless.

The Number of Cats

Never assume that a litter box can handle the waste of more than one cat. If you have two or more cats, be sure to buy a multi-cat one. These models have a bigger capacity, a larger frame, and a heavier build.


Why You Should Trust Us

Over the last two years, weve spent a lot of time figuring out what it takes to make a great automatic litter box.

Weve researched the types of boxes available, read hundreds of customer reviews, and performed real-world tests on the top automatic litter boxes. We spent over 60 hours testing these litter boxes, paying attention to key factors like thoroughness, odor control, and long-term reliability.

Based on this extensive research and hands-on testing, weve selected the following automatic cat litter boxes as the best you can buy.

Worlds Best Cat Litter

Worlds Best doesnt quite live up to its lofty name, but this is nevertheless a quality litter thats worthy of your consideration.

One of the biggest selling points for this option is its safe for your septic tank, allowing you to flush clumps as needed. This cuts down on waste that goes to landfills, while also eliminating any smelly litter sitting around your house.

The bag claims that this is a dust-free formula, but we didnt find that to be the case. Youll still have a bit of a mess to clean up every time your cat covers up after herself, and it does little to control odors, so youll want to flush it ASAP.

Worlds Best does clump very quickly, though, so you shouldnt have to wait very long after she finishes her business before you can clean up. Shell probably wonder why youre lurking around the bathroom, though, so expect a few judgmental stares on her way out.

Can You Use Regular Litter In An Automatic Litter Box

Cat owners are only too familiar with the task of cleaning the litter box, and some may choose to spend some extra money and purchase an automatic litter box. If you would rather not clean the litter box several times a day, a self-cleaning litter box may be the way to go. There are a variety of automatic litter boxes available, some are covered, some are more traditional and open, while others are round, rectangular, or oval-shaped. If you are considering an automatic litter box, its important to know what kind of litter to use, and we will answer the question of can you use regular litter in an automatic litter box?

There are many automatic litter boxes on the market, and these litter boxes work by either raking or sifting waste into a separate, sealed compartment. This must be emptied regularly to keep the automatic box functioning how it should. Another factor is that regular litter cannot be used in an automatic self-cleaning litter box and that certain types of cat litter work better than others when it comes to keeping the litter box functioning the way that it should.

Testing The Health Monitoring System

5 Best Automatic Self-Cleaning Litter Boxes (We Tested Them All)

Fortunately, my cats urine seemed to be within the healthy pH range throughout the testing process.

Because I wanted to see how the litter would respond to different pH levels, however, I ran an experiment using three different solutions:

  • Water with baking soda
  • Plain water
  • Water with vinegar
  • After pouring the solutions into separate containers of Pretty Litter, I noticed the colors changing and deepening over time. They achieved their deepest color a few minutes after pouring.

    Here is what the different colors indicate:

    • Red May indicate a Feline Lower Urinary Tract Disorder , kidney stones, bladder stones, bladder inflammation, kidney disease, or clotting disorders. In rare cases, it may also indicate bladder cancer or internal injury.
    • Orange May be a sign of metabolic acidosis, kidney tubular acidosis, or calcium oxalate crystal formation.
    • Blue or Dark Green May indicate certain types of urinary tract infections and an increased risk for crystal/stone formation.
    • Dark Yellow/Olive Green Indicates urine within the typical pH range.

    Its important to note that Pretty Litter is a tool that provides insight into your cats health but should not be used as a replacement for medical diagnostics or veterinary care. If the product indicates a potential health problem, take your cat to the vet.

    Is An Automatic Litter Box Worth It

    If you are looking for convenience, and would rather not stoop over and clean the litter box multiple times per day, then an automatic litter box is worth it. They cut down on cleaning time, can reduce odors, and make it easier to get out of town for a few days without having to hire a cat-sitter. If you plan a long weekend away, having a self-cleaning litter box might make it that much easier for you and your cat.

    Smartcat All Natural Clumping Litter Premium Choice

    CatGenie Self Washing &  Flushing Cat Litter Box  Automatic Cleaning

    SmartCat All Natural is a great option for users who are tired of dealing with dust and clay, as its made purely of grass seed. The end result is a litter that clumps well without sending powder all over your home.

    Its especially good for those who dont like dealing with wet clumps of urine, as it hardens until all the moisture is absorbed. This creates a hard ball that comes out easily and isnt likely to fall apart between the box and bag.

    Grass seed weighs half as much as clay, so youll find that a 20-pound bag of this stuff lasts about twice as long as a similarly-sized bag of traditional litter. Thats good because its probably at least twice as expensive as the regular stuff.

    One other issue we found with the SmartCat All Natural was the fact that the animals tend to track it all over the place, so if you buy it, make sure you have a mat outside the box . Thats an easy fix, though, so its not worth knocking this litter down more than a spot or two.

    • Gets tracked all over the place

    Are Automatic Cat Litter Boxes Worth It

    Trust us when we say theyre worth every penny. There are tons of benefits of automatic litter boxes. Here are but a few:

    Save Time

    When youre working most of the day, travel often, come home late, or youre just busy in general, these litter boxes can save you precious time time you could spend playing with your pet.

    Highly Hygienic

    As these boxes are configured to clean themselves, theres no risk of forgetting to empty the litter box. Your cat will be grateful, and you wont have to deal with remembering to clean it.

    Less Odor

    Having an automatic litter box means regular cleaning, which leads to much less odor in your home.

    Less Contact with Cat Waste

    Cat waste, like any other waste, is not only gross, but its also dangerous. Accumulated cat waste releases ammonia that can be dangerous to human health. It can cause respiratory issues and bacterial and parasite infections.

    Keeps Your Cat Indoors

    Indoor cats live much longer than outdoor ones. A self-cleaning litter box will keep them inside for longer, prolonging their life.

    Healthier and Happier Cat

    Your cat may hold it in if their litter box isnt clean, which can cause urinary tract infections and cause more severe health issues.

    However, having a good self-cleaning litter box means always having a clean box and a happy and healthy cat.
