The Best Self-Cleaning Litter Boxes: Our Top 6 Recommendations
Now that you know what it takes to make the best self-cleaning litter box for cats, let’s review the top products on the market.
What Should You Look For in an Automatic Cat Litter Box?
The Best Automatic Kitty Litter Box Doesn’t Jam
Cleaning cat litter is a sticky business, and many automatic litter boxes struggle with it. While testing automatic litter boxes, we found that many of them got jammed and backed up. Some couldn’t get through a single large clump.
We looked for automatic litter boxes with strong enough sifters to power through clumps large and small without malfunctioning.
The Best Automatic Litter Boxes Clean Thoroughly
When used with the right type of cat litter, great automatic litter boxes should be able to clean out your cat’s waste without leaving chunks and residue.
In our tests, we found that bad automatic litter boxes tended to let messy bits fall under the litter bed or into other crevices in the unit. To avoid this problem, we looked for boxes that featured a strong rake or sifter with holes tight enough to catch and remove small pieces.
That’s why we also looked for units that were well-sealed without a lot of gaps and cracks that could collect mess.
It Should Be Good at Controlling Odors
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 a week or more before making a trip to the garbage can.
Look for Boxes That Work With The Type of Litter Your Cat Prefers
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.
If your cat doesn’t like the type of litter that the box requires, you’re out of luck. Consider this before choosing a self-cleaning litter box and make sure your cat likes the type of litter it requires.
The Best Automatic Litter Boxes Let You Monitor Your Cat’s Activity
Your cat’s litter box activity is one of the best indicators of their health status. That means that your scooping sessions are one of the best opportunities to learn how your cat’s doing.
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 with an activity log in a connected app or other means of monitoring your cat’s box usage.
To ensure that you don’t lose track of your cat’s litter box activity, choose a health monitoring box.
