However, there might be times when you see your cat lying in their litter box, even in areas where they have relieved themselves. If this occurs, there’s usually an underlying cause, either medical or behavioral, that is making your cat exhibit this unusual behavior.
The 6 Reasons Cats Lay in the Litter Box
1. They Are Marking and Defending Their Territory
Some cats like to make sure their domains are never compromised by another person or animal. If your kitty is new to your family or is required to accept another cat or dog into the household, they may use their litter box to mark and defend their territory.
While male cats are notorious for marking and defending their territory, any cat might display this behavior.
To ensure a harmonious environment for your cats, it’s essential to provide enough litter boxes in the house—specifically, the number of litter boxes should equal the number of cats plus one. This prevents competition for resources. Additionally, make sure there are enough food and water bowls, resting spots, hiding places, perches, toys, and scratching posts available. Using a pheromone diffuser can also be beneficial, as it emits ‘harmony’ messages to help restore peace among cats living together. With the right resources and support, your cats should feel comfortable sharing your home.

2. They Are Dealing With a UrinaryProblem
Urinary issues are not uncommon in cats. In cases like these, they might lie in their litter box or they may avoid it; both situations can occur. You should observe your cat and pay attention to any changes in their urinary habits. If any abnormality is detected, it’s time to take action.
Take your kitty to the veterinarian to determine what the problem is. They will probably run some basic tests to understand the issue and create a treatment plan to help your cat recover as quickly as possible.
3. They Are Pregnant With Kittens
Females that have not been spayed can get pregnant, even if you have not witnessed the mating. If they are not living with an unneutered cat, they might get outside for a few minutes and become pregnant by a stray male. If your cat becomes pregnant, she may start to lie in her litter box to prepare for her new brood of kittens. She’s trying to give birth in a place that makes her feel comfortable and in control, and to her, a litter box will keep the kittens contained in a safe space until they can see, explore, and eat on their own.
Give your pregnant cat a safe, clean place to have her babies, like a box or kennel with bedding. Make sure the birthing space is comfortable and has walls high enough to keep new kittens inside. If necessary, place the prepared box or kennel next to the litter box to make your female feel the most confident.

4. They Are Having Digestive Difficulties
Some cats develop problems with their digestive system. If they eat something that they are not used to, they eat too much, or they have some kind of gastrointestinal condition that impairs proper digestion, they might want to spend more time around the bathroom than normal. For example, constipation can make a cat feel like they have to go to the bathroom for hours before they can actually go. In this case, they might stick around their litter box until the “deed” happens.
Set up a basic food regimen that includes nothing more than your cat’s regular mealtime recipe, whether that’s commercial or homemade food. Avoid treats and extra snacks. If the digestive problems don’t subside within a couple of days, contact your veterinarian to schedule a checkup.
5. They’re Too Old to Go Too Far From the Bathroom
When cats get old, they are less likely to be able to manage their bathroom habits. Some cats cannot hold their feces and/or urine for long enough to reach a litter box. Others may find it difficult to come in and out of the litter box due to painful joints, and they might spend some of their time lying in their litter box to ensure that they don’t have any accidents in the house. Sleeping in or near the litter box minimizes the risk.
Provide your older cat with a low-sided litter box and place additional litter boxes around the house so they feel more comfortable with being able to make it to the bathroom when they feel the need to relieve themselves. The closer their sleeping quarters are to the litter box, the less likely they will actually sleep inside.

6. They’re Trying to Reduce Stress Levels
If your kitty has experienced a significant change, like moving to a new house or living with a new household pet, chances are that they are trying to find a way to deal with the stress that comes with sharing or establishing new territory. Until your cat feels comfortable again in their own household domain, they might be found lying in their litter box, where their scents are most powerful and where they feel like they have dominated the space. They don’t want to spend time in any place that they don’t feel is theirs completely.
To get your cat to stop lying in their litter box when they’re feeling stressed out, create a comfortable and safe space for them to hang out, where people and other animals are not constantly moving through. Once they feel safe in these surroundings, their stress levels should reduce, and they should naturally start to make more of an appearance in the family environment.
Frequently Asked Questions (FAQ)
There are a few common questions that people have when it comes to their cat lying in the litter box. Here are the accompanying answers to peruse.
Can a Cat’s Behavior Be Changed Once They Start Lying in Their Litter Box?
Yes! It takes patience and adjustments, but figuring out how to meet your cat’s needs is all that it should take to stop them from lying in their litter box.
What If I Can’t Figure Out Why My Cat Is Lying in the Litter Box?
It’s a good idea to schedule a checkup appointment with your veterinarian to rule out any health conditions that could be causing the behavior. If everything checks out, your vet may be able to help you determine the reason (which may have to do with their quality of life) so you can effectively address the situation.
Can a Different Type of Litter Box Fix the Problem?
Switching to a litter box with a cover and/or high sidewalls can help deter your cat from wanting to get inside and lie down in the litter. However, if there is a reason for this behavior other than it just being a weird habit, a different type of box may not fix the problem.
