Cat Not Using Litter box: 13 Reasons Explained
Cats are clean animals, so they quickly learn how to use the litter box and avoid making a mess all over the house.
Still, inappropriate elimination is more common than you think. According to the ASPCA, at least 10% of all cats develop elimination problems.
But why do cats stop using the litter box? Usually, cats refuse to use their litter box because of behavioral issues or underlying medical conditions.
Since it’s crucial to resolve this issue as soon as possible, let’s discuss the most common reasons.
1. Dirty Toilet
As a study concludes, cats prefer a clean box to a dirty one, even if another cat has used the toilet box before.
That’s because cats have an excellent sense of smell and hate the scent of dirty toilets. And most cats don’t like to step into their waste or dig around it.
So, when you don’t remove the urine clumps and feces from the box, your cat will find an alternative bathroom stop.
2. The Box is Too Small
If your cat is not using a litter box, you should think about whether you have a suitable toilet box size.
It should be at least one and a half times the length of your cat, measured from your cat’s nose to its tail.
If the box is too small, your cat won’t have enough space to turn around and bury its waste. And your cat may also end up peeing just outside of the litter box.
3. Non-Accessible Location
Cats not using the litter box can be due to the wrong litter box location.
The toilet box shouldn’t be where cats feel trapped, in a high-traffic area, or in a difficult-to-access room.
My cat refuses to use the litter box when I place it near her cat food and water bowls.
Some cats also don’t like it when the toilet is close to the washing machine or another loud household object.
4. Type of Litter Box
Getting a toilet box for your furry friend is much more than going to the pet store and picking the first one you see.
Some cats like high-sided toilets, while others prefer low-entry boxes. And not all cats are fond of covered toilets or self-cleaning litter boxes.
5. Household Stress
Why is my cat eating litter pellets or snacking on clumping litter?
Think about peeing outside the box as your cat’s way of asking for help. Cats under stress can also start urine marking around the house, lose appetite, or hide under the bed.
6. Type of Litter
In general, cats prefer clumping litters with a fine texture and no added fragrances or scents.
Moreover, some cats avoid the toilet box if you haven’t poured enough substrate to satisfy their digging preferences.
7. Urinary Tract Infection
Why did my cat stop using the litter box all of a sudden?
Your kitty might have a urinary tract infection, which causes painful urination, frequent urination, or straining to pee.
When cats are in pain when using the toilet box, they think the box is what makes it painful to pee. So, they find alternative spots to do their business.
8. Other Medical Reasons
Besides cat UTIs, other medical issues can also make it painful for your cat to use the bathroom, such as:
- Kidney stones or kidney failure
- Bladder stones
- Thyroid disease
- Interstitial cystitis
- Constipation or diarrhea
9. Multiple Cats
According to studies, multiple cats are one of the most common risk factors for inappropriate elimination around the house.
It makes sense because cats don’t always get along with each other. One cat can block access to the toilet box or attack the other when using the bathroom.
It’s normal for young kittens to have accidents until they learn where the toilet box is and what it is for. It’s a matter of patience and training.
Older cats also often stop using their toilet box because of a decline in mobility, dementia, joint pain, and incontinence.
So, a senior cat suddenly not using the litter box is a cause for worry.
11. Bad Experience
Why has my cat stopped using the litter box? Think about how you react when your cat makes a mess outside of its usual bathroom spot.
Some pet owners punish their cats whenever they find a urine puddle on the floor. However, scolding or yelling at the cat is counterproductive and makes the problem worse.
Moreover, cats can become afraid of their toilet if something startles them in the middle of peeing or another animal beats them there.
12. Not Enough Litter Boxes
Not enough litter boxes around the house can be the reason your cat is not using the litter box.
You need one box per cat plus one extra to promote good litter box habits.
13. Surface Preference
When you ignore your cat not using the toilet box, some cats develop a surface preference for carpeted surfaces, soft bedding, or floors.
How To Get A Cat to Use the Litter Box Again
So, your cat is peeing outside the litter box or pooping on the carpet. First, you shouldn’t blame your cat or think she is doing it out of spite.
Instead, use these nine tips on what to do when a cat stops using the litter box.
1. Schedule a Vet Visit
What should you do when a cat stops using the litter box? Talk to your vet as soon as possible so that your vet can do blood tests to rule out a medical issue.
Keep an eye on other warning signs that your cat is sick, such as blood in urine or feces, straining to urinate, frequent urination, increased thirst or hunger, or loss of appetite.
2. Make the Other Location Undesirable
To encourage your cat to use its toilet, make the alternative bathroom location undesirable.
You can use some smells that cats hate to keep them away from flower pots, or put plastic liners or aluminum foil on furniture.
And don’t forget to clean the mess with enzymatic cleaners to remove all traces of cat urine odors, or your cat will return to that spot.
3. Switch to Unscented Litter
As I already said, cats don’t like certain smells and fragrances. So, switching to an unscented brand can make all the difference.
4. Experiment with Different Litter Boxes
You should provide several boxes of different sizes and designs filled with different types of litter.
Likely, one will be up to your cat’s preferences, and once you discover what your cat likes, it’s easy to get them back to using the litter box.
5. Train Your Kitty to Use the Toilet Box
Sometimes kittens just don’t know where they are supposed to pee or poop.
You can encourage them to use the provided toilet box by placing some of their poop or pee inside the box.
6. Consider medication
As vet specialists from VCA explain, “When frustration, stress, anxiety, or marking are suspected to be the cause, drug therapy and behavior modification techniques may be effective.”
You can talk to your vet about prescribing anti-anxiety or calming medication to reduce your cat’s stress levels and make them feel safe.
7. Change Location
Move the toilet box away from your cat’s water and food bowls.
Choose a low-traffic area where cats feel safe and are not separated from the family.
8. Resolve Conflicts
Keep your cat’s routine as stable as possible and resolve conflicts with other cats in the household.
Stop any bullying attempts and keep a journal of when and where your cat pees or poops to find a possible conflict or stress trigger.
9. Add an Extra Box
Even if you have enough toilet boxes for your cats, it’s worth trying to add an extra one. Some cats pee in one box but poop in another.
Do cats poop on the floor when they are mad?
No, cats don’t poop on the floor when they’re mad. But why does a cat poop outside the litter box? Usually, cats poop outside the box when it’s too dirty or the cat is in pain.
Why is my cat peeing everywhere all of a sudden?
Why is my cat peeing outside the litter box? Usually, cats pee everywhere all of a sudden because they’re ill or the toilet box is too dirty.
How do you know if a cat has a UTI?
The usual symptoms of UTI in cats are straining to urinate, frequent urination, inappropriate urination, blood in urine, crying when peeing, and excessive genital licking.
It’s not normal for your cat to avoid its toilet box, especially if you scoop it on a daily basis. So, a cat no longer using its litter box is a red flag that something is wrong.
Your cat is not doing it because she is mad, jealous, or stubborn. Instead, your kitty is trying to communicate its problems in the only way possible.
As such, you shouldn’t ignore inappropriate elimination and try to find the reason behind this unwanted cat behavior.
