Cat Not Using the Litter Box? Here’s Why (And What You Can Do)
You brag to your fellow cat parent pals about how quickly and easily your new pet took to litter training. Then, years later, your cat has stopped using the litter box. A cat not using the litter box definitely can be frustrating—and unsanitary. Instead of doing their business where they’re supposed to, your cat is pooping outside the litter box, peeing outside the litter—or both!
“Some may only urinate inside, while some may only defecate inside,” says Rachel Barrack, DVM, CVA, CVCH, owner of Animal Acupuncture in New York City. “Some cats abruptly refuse the litter box altogether.”
In all scenarios, it’s exasperating to say the least—and it’s important to resolve the issue before your cat makes a habit out of eliminating in inappropriate places. But you can’t resolve it until you figure out what’s causing it in the first place.
“There are many reasons a well-trained cat suddenly stops using the litter box,” Dr. Barrack says.
While often the reason is relatively easy to fix, other times it can signal something more serious. Even if you think you know the cause, it is recommended that you schedule an appointment with your veterinarian to rule out any underlying medical conditions, Dr. Barrack emphasizes.
6 Reasons Your Cat Stopped Using the Litter Box
1. The Litter Box Is Different
Did you move the litter box to a new area, buy a new box, or switch litter? It might seem like a minor thing to us—but “cats develop preferences to certain litter and boxes,” Dr. Barrack says.
For example, if you switched from an open litter box to one with a hood, the hood itself may be what’s putting off your kitty.
“Many cats do not like hooded litter boxes because their instincts tell them that a contained space is dangerous,” Dr. Barrack explains. “Even if there is no immediate threat, the fact that there is no space for them to escape in case of an emergency is enough to make a cat uncomfortable and avoid using the litter box.”
These switches can be especially problematic if you make them all at once—and may lead to your cat peeing outside the litter box.
Solution:
You can avoid this litter box problem by making subtle changes.
“If you’ve found a new and better spot for the litter box, move it a few feet every couple of days until it’s in the desired location,” Dr. Barrack says.
The same goes for when you purchase a new brand or type of cat litter.
“Try mixing it with the old litter, adding less and less of the old litter with each litter pan cleaning,” Dr. Barrack advises.
FurPetVo’s Ultra Litter Attractant can also be used to gently entice your cat to use the new litter.
2. The Litter Box Smells
The reason why your cat stopped using the litter box may be right under their cute, little (and very sensitive) nose: It stinks! Cats like a clean litter box—and will have no problem opting for a potted plant if their designated space isn’t up to their standards.
Solution:
“The pan should be scooped out every single day, and then washed out and refilled with fresh litter at least once a week,” Dr. Barrack says.
You can also try a cat litter with strong odor-eliminating attributes. FurPetVo Multi-Cat Clumping Cat Litter, for example, is formulated to effectively neutralize odors your cat leaves behind. For an extra odor-eliminating boost, try FurPetVo’s Cat Litter Deodorizer Powder.
3. The Litter Box Is Too Small
If your cat is peeing outside the litter box, take a good look at both your cat and the box. Did you buy it when your cat was a kitten? Or maybe your older cat has put on some weight. Cats can outgrow their litter box—and then refuse to do their business in a space that’s too small for them to get comfortable.
Solution:
“Make sure [the litter box] is large enough—about one and a half times the length of your cat is a good rule of thumb,” Dr. Barrack says. “They should be able to easily turn around in it. If they can’t, you should get a bigger box.”
The FurPetVo Roll’N Clean Cat Litter Box comes in a large version that is 23 inches long—ideal for bigger cats.
4. Kitty Bullies
Yes, really. “Multi-cat households develop a hierarchy, and cats can pick on each other—preventing litter box usage to establish dominance,” Dr. Barrack says.
Solution:
Dr. Barrack suggests making sure that each cat in the household has their own box—ideally placed in different parts of your home.
“Some parents of multiple cats have one extra box to ensure this sort of problem doesn’t happen—which is a good idea,” Dr. Barrack says.
5. Stress
Cats can pick up on household stress—whether it’s the arrival of a new family member (human or pet), a move, or a new job that requires you to be away more.
“Cats, much like preschoolers who regress in potty training, can act out when they’re stressed,” Dr. Barrack says.
Solution:
If you and your veterinarian determine stress is the cause of your cat not using the litter box, try to establish a routine for your kitty moving forward.
“If things are hectic at home, make an effort to keep your cat’s life as consistent as possible—as far as feeding, playtime, and sleeping go. A few extra cuddles can’t hurt, either!” Dr. Barrack says.
6. A Medical Problem
If it hurts to urinate and/or defecate, cats can understandably be reluctant to use the litter box, says Dr. Barrack.
“Urinary tract infection, feline interstitial cystitis, bladder or kidney stones, and constipation can all be causes of your cat not using the litter box,” she says. “Also, older cats may have developed arthritis or another condition that makes getting into and out of the box challenging.”
Solution:
Dr. Barrack advises consulting your vet right away if your normally well-trained cat of any age abruptly stops using the litter box. They can test for and diagnose any possible medical reasons—and provide recommendations for treatment.
When your feline companion mysteriously avoids the litter box, it’s upsetting—to you as much as to your cat! But by running through this checklist of common causes—and staying in close communication with your vet—you can get to the bottom of why your cat stopped using the litter box. Before long, your furry friend will be acting like themselves again.
