The Best Self-Cleaning Litter Boxes: Our Top 5 Recommendations
Now that you know what it takes to make a great automatic litter box, let’s review the top products on the market.
What Should You Look For in an Automatic Cat Litter Box?
Great Automatic Litter Boxes Don’t Jam
Cleaning cat litter is a sticky business. A pile of clumped-up litter can get you in a jam, especially if you’re a machine with a limited range of motion. For that reason, automatic litter boxes are notorious for jamming.
So how can you spot the jam-prone automatic boxes before you buy them? Certain designs are more prone to jamming than others.
Litter boxes that pair clumping litter with a raking mechanism tend to collect gunk, but not all have the same problems. It’s important to evaluate customer reviews to get a snapshot of your potential future.
A Good Automatic Litter Box Cleans Quickly and Effectively
Remember that your cat can’t do their business when the automatic litter box does its business, so don’t choose one that’s much slower than a human with a scoop in her hand.
Besides working quickly, the automatic litter box should deliver a complete clean. Again, compare the automatic litter box to yourself. What’s the use of a self-cleaning box that leaves clumps and chunks that you’d sift out?
Besides working time and speed, think about noise levels. Automatic litter boxes can be scary, and the noisy ones are the most disturbing of all.
The Best Automatic Litter Boxes Control and Contain Odors Well, Even in Multi-Cat Homes
Except for the toilet-style CatGenie, automatic litter boxes don’t make your cat’s waste disappear completely.
Instead, they store it within an odor-trapping waste bin. These compartments should contain odors effectively and should have a large capacity, allowing you to go for weeks before making a trip to the garbage can.
The Best Automatic Litter Boxes Fit Within Your Budget
One of the top questions people ask about automatic litter boxes is “are they worth it?”.
The answer to that question involves a cost-benefit analysis that only you can perform. It’s a good idea to recognize that the most expensive boxes aren’t always the best. Realize, also, that the cost of the litter box is more than the number in the Amazon checkout.
Like a cheap printer that costs you hundreds of dollars a year in ink, the real cost of the litter box adds up over months and years of use.
Some litter boxes will drain your wallet as you pay for special litter and maintenance. Others will save you money by cleaning more efficiently and allowing you to use the same litter longer.
The Best Automatic Litter Boxes Are Compatible With Litter Your Cat Likes To Use
Some automatic litter boxes only work with certain types of litter. The PetSafe ScoopFree litter box, for example, is only compatible with crystal cat litter. The CatGenie won’t work unless you fill it with proprietary plastic pellets.
These arrangements are problematic for multiple reasons. You’re stressing your cat by introducing a new type of litter in addition to a strange new litter box.
If your cat doesn’t like the type of litter that the box requires, you’re out of luck. By selling a litter box only compatible with proprietary litter granules, the manufacturer is locking you into their high markups for life.
Ideally, choose an automatic litter box that is compatible with the type of litter your cat prefers.
Great Automatic Litter Boxes Allow You to Monitor Your Cat’s Health Status.
Your cat’s litter box activity is one of the best indicators of their health status, and when their box does the work for you, you’re missing out on an opportunity to evaluate their wellbeing.
Some automatic litter boxes make up for this shortcoming by incorporating use counters or other means of monitoring your cat’s box usage.
Transition Tips: How To Help Your Cat Start Using a New Automatic Litter Box
Between operational noises and unexpected movements, a self-cleaning unit is a little bit more disturbing than the standard inanimate plastic pan.
For cats who grew up using a traditional litter box, it might not even be clear that the new litter mixing machine is a litter box at all. It’s important to gently acclimate your cat to the new litter box.
Remember That if Given the Choice, Your Cat Will Probably Opt For What’s Familiar
Instead of removing your cat’s old litter box immediately, think about just leaving it dirty. Your cat will recognize the superior cleanliness of the automatic litter box and choose it instead of the one that hasn’t been cleaned for a few days.
Help Them To Understand That This Thing Is a Litter Box
Cats instinctively bury their waste and seek out soft, dig-able substrates. But after years of using one litter box, the introduction of another strange-looking litter box could leave your cat unsure of what to do.
Tell your cat that this is their litter box in no uncertain terms – place a scoop of their old litter in the new litter box. Your cat’s ultra-sensitive sense of smell will help them to read the message.
Let Your Cat Use the New Litter Box a Few Times Before Turning It On
The noisy movement of an automatic litter box can be jarring, so you may prefer to allow your cat to first accept their new toilet without the added disturbance of its self-cleaning functionality.
Going into your full review it looks as though you didnt like the littermaid. I have 3 cats and used Cat Genie for many years but the price is too much and support doesn’t want to help unless you buy the unit from them.
Hi Anne! Mallory did the testing for Litter Maid but I do a lot of the written reviews, so I’m familiar with all the options. All of the automatic litter boxes we’ve tried have their faults. None of them seems to be a completely hassle-free solution. The Litter Maid’s issues with leaving behind small clumps, I think, is mostly due to the rake-and-tray design. I noticed similar issues with the PetSafe ScoopFree and the ChillX AutoEgg. If you’re looking for a more affordable option than the Litter Robot, the Litter Maid isn’t necessarily a bad choice. We still rated it 8.2 out of 10 overall!
Hi,
Have you tested Leo’s Loo? Seems to have mixed reviews, but mostly good. It’s slightly cheaper than the Litter Robot.
Hi Laura,
We have not tested it yet, but it is on our list for sure.
I have had three Litter Maid boxes. Two worked well and lasted a couple years for $100 each. They however had metal rakes and didn’t stick and also went to bottom of box much closer. The third one came with the plastic rake so I figured the original maker sold the patient to a company and they cheapened it to make more $$$. The last one had problems quickly one of which stopped it from being automatic. Wrote company a couple times and no reply. I don’t see how this litter box can make any good product list! “IT isn’t and I think I have more , much more time using it than you.
Hi Robert,
Thank you for commenting, and yes you are on point that this litter box does have problems reported by other cat parents as well. It’s on the list as budget friendly alternative. It is troubling that the company does not take care of its customers nor take the time to reply to their emails. We’re going to take this into consideration in our up and coming article update.
Thank you!
Thank you for the info as I am considering purchasing an automatic litter box. I am 64 and tired of hauling around 42 pound packages of litter 2 times a month. Also getting down on my knees to scoop out the litter box is getting harder. I am still trying to decide as I have 3 cats and not sure how the Cat Genie would handle 3 cats and one is a big guy!
