Your cat has started sleeping in the litter box, and the tray is no longer empty. That may look like an odd preference, but a change in resting place is often worth a closer look at both health and environment. The first question to ask is very simple: is the cat actually urinating normally?
A cat that stays in the litter box for long periods may appear to be resting when it is really trying to pass urine. It is important to distinguish that from a newly arrived cat that has simply chosen the litter box as the only familiar hiding place in an unfamiliar home.
First priority: check whether urination is normal
Watch closely to see whether the cat repeatedly assumes the posture to urinate and whether any urine is actually produced. Repeated attempts without success, vocalising, unusual genital licking, or obvious lethargy all justify an immediate call to a veterinarian. Do not wait until the next day, especially if the cat is male.
Guidance from Cats Protection on urinary problems notes that an inability to pass urine may indicate a blockage. Do not press on the abdomen, and do not try to manage the problem with a litter change, herbal remedy, or human medication.
In a multi-cat household, the presence of clumps in the tray does not prove that the cat in question is urinating normally. Observe the animal individually, and do not delay seeking help if any worrying signs are present.
If the cat is urinating: why has the litter box become a refuge?
After adoption, a move, or another major change in the home, a cat may look for a small, enclosed, familiar place. A covered litter box can become the only immediate “safe den” available. That does not mean sleeping beside the toilet area is a healthy arrangement to keep in place.
Offer a separate hiding spot nearby but clearly apart from the litter box: a sturdy open cardboard box, a sheltered bed, or a carrier made comfortable with a familiar blanket. Let the cat choose. Repeatedly pulling it out by force usually makes the new resting area feel even less secure.
The Cats Protection advice on cats that hide stresses that a cat should be able to retreat and come back out at its own pace. A useful hiding place must remain accessible without forcing the cat to cross a path where it may be startled or intercepted.
Review access around the home
Can your cat still reach its usual bed easily? Stairs, a ledge, or a jump up to a favourite spot can become difficult when there is pain or reduced mobility. Set up a low, stable, comfortable alternative and then look for the reason behind the change.
Also pay attention to social dynamics. Another cat may quietly block a corridor or wait near the exit of a hideaway. Spread water, food, litter boxes, and resting places across several locations. Resources placed side by side do not always represent real choice.
Keep the litter box clean without changing everything at once
Keep the tray clean and continue using a litter the cat already knows during this period. Avoid changing everything at the same time: the box, the litter, the location, and the scent. If you alter all of them together, it becomes impossible to tell which factor is helping or making things worse.
If the box is too high, too small, or difficult to reach, look for a better-suited model. Choosing a litter box for a cat often comes down to size, access, and comfort. A litter mat can help reduce tracking around the house, but it is only a cleaning aid; it does not solve the underlying reason the cat is sleeping in the tray.
What to note before the veterinary visit
Record when the behaviour began, whether the cat is eating and drinking normally, how it is moving, and what you observe during toilet visits. A photo of the setup and a short video of the behaviour can be useful additions to your notes.
Do not give a sedative to make the cat leave the litter box. If the behaviour continues or appears without any obvious change in the home, have the cat examined even if it seems to be sleeping peacefully.
How a return to comfortable resting looks
Progress is visible when the cat starts using a separate bed, moving around freely, and accessing resources without hesitation. Keep several resting options available; not every cat wants a raised perch. Advice on cat trees and retreat spaces can help you choose according to your cat’s abilities.
Do not remove a hideaway too quickly just because it is less attractive than a new basket. At this stage, a place where the cat feels safe enough to sleep matters more than a perfect arrangement for a photograph.
