Finding the best litter box for multiple cats can be a process of trial and error as you test-drive different litter boxes to see what your cats like best!
In multi-cat families, finding the perfect litter box system can get even harder because some cats like to share litter boxes while other cats wouldn’t dream of going where another cat just went!
For you, the cat owner, this can be especially mystifying as you study your cats’ habits and try to decipher which cat prefers what litter box and how to select the best litter box for multiple cats in your household!
Why offer multiple cat litter boxes for multiple cats?
Today’s feline wellbeing research shows the best litter box for multiple cats is usually more than one litterbox.
It turns out nothing puts a cat off their business like the sight of another cat’s business already in the tray.
And when they can’t relax in the litter tray, they’re more likely to use another unintended corner of your house for their toilet.
The magic formula for making sure more than one cat all use a litter box when they answer the call of nature is one litter box for every cat, plus a spare.
So if you have two cats, you need at least three litter boxes. If you have three cats, you need at least four litter boxes, and so forth….
Once they’re in place, start observing how differently your cats behave while using the litter box.
Different cat have different toilet habits
For example, you might have one kitty who will come and go so silently you’ll never even know she, well, went.
Then you may have another cat who simply insists on announcing his entry into the litter box at top volume and concluding his business by flinging “gently used” cat litter surprisingly far distances.
Also, while some cats may use just one litter box, other cats in the same family may insist on using every single litter box you provide.
And while some cats prefer a hooded box with a door flap, others will only go in an open-air box.
We don’t really know why these head-scratching feline behavior differences exist, but we do know they are important to cats.
We also know you can do a lot to help your cats answer nature’s call with privacy and comfort by providing multiple private and roomy kitty litter boxes.
How to choose cat litter boxes for multiple cats
As any feline behavior expert, veterinarian or experienced cat owner will tell you, finding the best litter box for multiple cats begins and ends with size.
Just like most people don’t love having to squeeze themselves into and out of a postage stamp-sized bathroom, cats prefer to have plenty of space to stand up, stretch, turn around and select the best spot.
Speaking of which, your cats will also appreciate being able to find a clean (unused) space inside the litter box every single time they need to go.
For this reason, choosing a roomier litter box can translate into less scooping time for you!
