What causes inappropriate urination in cats? How to deal with sudden litter box issues and prevention tips

Many cat owners often think, "My cat is so smart, they use the litter box without even being taught!", only to later worry, "They've started to soil the bed..." or "They suddenly started having accidents..."

Actually, there's always a reason why cats have accidents. Instead of giving up and blaming it on poor training, let's try to understand what your cat is feeling.

In this article, we'll explain the causes of cat accidents, how to deal with them, and how to prevent them.

What to do if your cat suddenly starts having litter box accidents...

It's often said that cats don't need litter box training because they naturally urinate and defecate in the litter box without being taught.

Cats have a natural habit of choosing soft sand to dig a hole to cover their waste in order to mask their scent.

Cat litter is designed with this feline habit in mind, which is why even kittens can use the litter box without much trouble.

Therefore, if your cat starts having accidents, suddenly starts having litter box issues, or stops using the litter box, it's safe to assume there's an underlying reason.

Is it on purpose? Reasons why cats have accidents

Cats are very clean creatures. They won't relieve themselves in places that smell of other cats or are dirty. They also dislike relieving themselves near where they sleep or eat.

If the litter box environment is like this, there's a high chance your cat will have an accident.

In addition to the litter box environment, accidents can also be caused by health conditions or heat cycles, so let's first consider the possible causes of accidents.

1. Dislikes the litter box environment

If your cat is unhappy with the litter box, they will start urinating or defecating elsewhere. First, check if the "litter box environment" is a place where your cat feels safe.

For example, cats dislike litter boxes that are:

• Dirty
• Smell of other cats
• Located in a noisy area
• Difficult to enter
• Too small
• Not their preferred type of litter
• Have too little litter

2. Environmental changes / stress

Cats are sensitive to environmental changes. Stress caused by moving or redecorating can lead to accidents.

Sometimes, a new cat, a new family member, or visitors can also trigger sudden litter box accidents. Some cats may even deliberately urinate outside the litter box to get their owner's attention.

Moreover, if accidents consistently happen when you're away from home, it could be due to separation anxiety.

Remember that cat accidents can be a sign of stress.

3. Physical decline 

As cats age, their physical abilities decline. This can lead to accidents because they can't climb into a high-sided litter box or can't make it to a distant litter box in time.

Accidents can also be seen in cats with dementia. Watch out for symptoms such as forgetting where the litter box is or being unable to relieve themselves properly.

4. Urinary tract diseases

Cats are at high risk for urinary-related diseases. Kidney disease and F.L.U.T.D. (feline lower urinary tract disease), which includes urinary stones and cystitis, often present with symptoms of "frequent urination."

They might dribble urine and have accidents, or fail to make it to the litter box in time. If your cat suddenly starts having litter box accidents, be cautious.

5. Marking due to heat cycle

Male cats will "mark" with urine to assert their territory.

Marking urine has a strong odor, and they will spray urine in various places. This spraying behavior is considered "deliberate soiling."

Furthermore, when female cats go into heat, male cats also enter their heat cycle in response to pheromones. To attract female cats, spraying behavior may increase during the heat cycle.

How to stop a cat from having accidents?

As mentioned above, there are reasons why cats have accidents. There are countermeasures and preventive measures for each cause of accidents.

However, scolding them loudly is not recommended.

This is because cats don't understand that they're being punished for doing something wrong; instead, they might perceive it as "If I use the bathroom here, I'll get attention!"

Here are some measures to prevent continued accidents:

1. Thoroughly clean the soiled area

Thoroughly clean any area where your cat has had an accident.

If any odor remains, they might perceive it as a litter box, so use unscented pet-friendly deodorizing sprays as well.

2. Keep the litter box clean

Cats are very clean creatures and dislike using dirty litter boxes.

Try to clean the litter box as often as possible, and once a month, replace all the litter and wash the litter box container with water.

3. Re-evaluate the cat litter and litter box

When a cat is dissatisfied with their litter box, you might see signs such as them perching on the edge of the litter box to relieve themselves or rushing out without covering their waste.

If the litter box itself seems to be disliked or difficult for them to use, consider changing the cat litter and the litter box entirely.

Cats generally prefer a litter box about 1.5 times their body length and about 5 cm of litter depth. For older cats, choosing one with a low entry point will provide peace of mind.

4. Change the location of the litter box

Since cats are vulnerable while relieving themselves, try to think like a cat when choosing a location for the litter box.

A cat's litter box should ideally be in a quiet, somewhat secluded spot. Also, try to place it as far away as possible from where they eat and sleep.

For multi-cat households, it's reassuring to have one more litter box than the number of cats living together.

5. Reduce stress

If your cat wants attention from you but doesn't get it, they can become stressed.

Anxiety can lead to accidents, so try to increase your bonding time with your cat and playtime with toys. It's also important to make arrangements for indoor exercise, such as cat trees or cat walkways.

Additionally, it's crucial to create a safe space for your cat, such as a quiet spot where they can be alone or a place where they can hide completely.

6. Get a health check-up

Urinary tract diseases could be the cause of accidents. If you notice any irregularities, such as frequent or increased urination, or unusual color or smell of urine, consult a veterinarian.

7. Spaying or neutering

Many cats stop spraying urine for marking after spaying or neutering. This also reduces stress from the heat cycle, so consider it as early as possible.

Summary

When your cat continues to have accidents, it's easy to feel "at my wit's end..." or "they're definitely doing it on purpose."

However, there's always a reason behind a cat's accidents. Consider whether it's due to the environment, their physical condition, or their heat cycle.

Accidents can also be an opportunity to notice changes in your cat's health.

Since kidney disease and other illnesses are a concern, it's a good idea to closely observe your cat's litter box habits and record any changes in the amount or frequency of urination.

If you notice even a slight irregularity, consult your veterinarian, bringing notes on your cat's litter box behavior.
