The main reason why a domestic cat might sleep in their litter box – as shown in the photograph below – is because it strongly smells of their scent due to the presence of poop residue (after it has been cleaned) which means that it is a reassuring place to them. This will be important to them if the general environment in which they live causes them anxiety which in turn means that they become stressed. To the comforting smell of their litter box, you can add the fact that it is an enclosed area and we know that cats like to sleep in enclosed areas like boxes. All in all, they have a very reassuring and calming place in which to snooze and sleep.
You might see show cats at cat shows sleeping in their litter tray which will be in a large cage because they are stressed by the noise and commotion of the cat show which are sometimes held in large, barn-like places which echo the sounds.
Multi-cat stresses
It is my view that if a domestic cat is sleeping in their litter box it is because the owner has got something wrong in creating a less than calm environment in their home. This is more likely to occur if the cat or cats are full-time indoor cats which compresses their home range which means that their home ranges have to overlap. This can result in bouts of aggression between the cats and if not, stresses can build up. It is well known that territorial issues are more likely to occur in multi-cat homes where the cats are kept indoors.
Some more options on this topic. There is an overlap with what I have stated above. This section is to complete the answer.
Cats might sleep in their litter box for a variety of reasons, although it’s not a common behavior and could be indicative of an underlying issue. Some potential reasons include:
- Comfort: Cats are known for seeking out cozy and enclosed spaces to feel secure. If a litter box has a cover or is in a secluded location, a cat might find it a comfortable place to rest.
- Stress or Anxiety: Cats might use a litter box as a hiding spot if they’re feeling stressed or anxious. This behavior could be a response to changes in their environment, such as new people, animals, or rearranged furniture.
- Medical Issues: Certain medical conditions can cause a cat to seek out cooler surfaces, like the material of a litter box. For example, if a cat has a fever or is experiencing discomfort, they might try to find a cool spot to lie down.
- Territorial Behavior: If the litter box is seen as the cat’s territory, they might be using it as a sleeping spot to mark their scent and establish ownership.
- Inadequate Sleeping Spots: If the cat’s environment lacks suitable resting areas, they might make do with what’s available, even if it’s a litter box.
- Litter Preference: Cats have preferences for the type of litter they use. If the litter is particularly soft or comfortable, the cat might choose to sleep there.
- Inappropriate Elimination: Sometimes, when a cat is having litter box issues such as urinating or defecating outside of it, they might end up sleeping near or in the litter box.
If you notice your cat consistently sleeping in their litter box, it’s important to monitor their behavior and assess whether any changes or issues might be causing this behavior. If the behavior persists or is accompanied by other concerning signs, it’s recommended to consult a veterinarian to rule out any potential medical problems and get professional advice on how to address the issue.
But it is almost always due to varying degrees of anxiety as the cat is seeing to feel better by being calmer. It is instinctive. It is an example of how cats feel emotion if anyone does not believe it! The sort of stress experienced can lead to health issues; commonly cystitis.
