Your cat is sleeping in the litter tray: what it means, and when to worry
Share
If your cat is sleeping in the litter tray, it is almost never a whim: either they are in pain or need to wee constantly, or they are stressed, or the tray is the only enclosed corner of the home where nobody can reach them. The vet comes first, a safe refuge second.
Why does a cat sleep in their litter tray?
A cat sleeping in their litter tray is looking for something the tray provides: instant access because they hurt, or shelter because they are frightened. Five situations come up again and again, and each calls for a different response.
| What is going on | What you notice | What helps |
|---|---|---|
| A urinary problem (cystitis, stones, a blockage) | Repeated trips to the tray, straining, little or no urine, blood, frequent licking | The vet, as an emergency if nothing comes out |
| Painful joints | Jumping less, grooming less, struggling to step over the edge of the tray | The vet, then a tray with a low side |
| A new arrival or a house move | They have just arrived, or home has changed; they stay hunched and watchful | An enclosed refuge of their own, and time |
| Tension with another cat | The other cat sits on their route; they avoid certain rooms | One resource per cat, plus one; a hiding place with two exits |
| Nowhere of their own | Children, foot traffic, noise; they hide under furniture | An enclosed bed that nobody disturbs |
Rows three and five share one thing: the cat lacks a refuge of their own. That is where an enclosed bed such as the single-entrance capsule cat bed comes in, once health has been checked. For the first two, no bed replaces an examination; for the fourth, a hiding place with two exits is the better choice.
When should you worry and see the vet?
See the vet as soon as a cat sleeping in the litter tray is also straining to wee. According to the Cornell Feline Health Center, the signs of lower urinary tract disease are difficult, painful or more frequent urination, crying out while weeing, blood in the urine, urinating outside the tray and frequent licking of the genital area.
The most serious case is a blocked urethra: the cat passes little or no urine and becomes increasingly distressed. Cornell calls it an absolute emergency: less than 24 to 48 hours can separate complete obstruction from death. Male cats are more at risk. More broadly, stress, living with other cats or moving house all raise the risk of urinary problems.
In an older cat, think about the joints too. According to International Cat Care, arthritis often goes unnoticed because cats hide their pain: they rest more, groom less, and may find the litter tray hard to use. The charity advises a tray with at least one low side.
Why does a stressed cat retreat to the litter tray?
A stressed cat looks for somewhere to hide, and without a proper hiding place, the tray, with walls on every side, can stand in for one. A Dutch study published in PLOS ONE notes that, with no hiding place available, stressed cats rest on high alert behind their litter tray: the authors read this as substitute hiding, because the tray offers some cover.
The same team gave a cardboard hiding box to 12 of 23 cats arriving at a shelter: their stress levels settled about seven days sooner than in the others. The sample is small and the study did not look at litter tray use, but it points the same way: a real refuge helps a stressed cat calm down sooner. It is the same need that explains why so many cats prefer a cardboard box to their bed.
A refuge of their own, away from the tray
A single entrance: nobody can approach from behind while they sleep, in a space that belongs to them alone, in flannel inside and out. Discover the capsule cat bed →
What if another cat is pushing them into the tray?
In a multi-cat home, the litter tray is one of the resources cats compete over. According to International Cat Care, cats may block or guard access to litter trays to stop others using them, block or defend beds, and use sleep, or pretend to sleep, as a way of coping with conflict. The cat lying in the tray may be guarding it just as easily as hiding in it.
The charity recommends one resource per cat, plus one extra, in separate locations: beds, trays, food bowls, high places. It advises against grouping trays together, which cats treat as a single resource, and suggests two access points to each perch so that no cat can be trapped there by another.
The same logic sets the limit of a single-entrance bed: faced with a cat lying in wait, it can turn into a dead end. In that case, a tunnel bed open at both ends works better. And the capsule remains a bed for one cat, even in XL: each cat needs their own.
How can you help them leave the tray for a proper bed?
To get a cat out of the tray, offer them something better than the tray, and never force it. Four steps, in this order:
- Keep the tray clean and where it is: moving it would add one more change for an already anxious cat.
- Put the refuge in the same quiet room, a few steps from the tray rather than pressed against it: they find the calm they were looking for, without the smell.
- Tuck in something that smells of them or of you: an old throw, a T-shirt you have worn.
- Never put them in by force. Keep the entrance clear and wait for them to explore it alone.
For an older cat, International Cat Care mentions igloo beds, which can help a senior cat feel warm and secure: the enclosed capsule works along those lines. Its product page does not give the height of the entrance; for a very stiff cat, check they can step in easily. If warmth is mainly what they are after, a cat sleeping bag they can burrow into also works.

Frequently asked questions
Should you lift them out of the tray when they are sleeping in it?
No. Lifting them out of their only refuge adds stress without solving the cause. Watch instead: are they weeing normally, how often do they visit the tray, do they get out easily? These notes will help your vet. One exception: if they strain with nothing coming out, go straight to the vet.
Does a covered tray encourage sleeping in it?
A covered tray can look more like a hiding place, but removing the lid without offering another refuge only moves the problem. International Cat Care suggests considering open trays in multi-cat homes, so cats keep a view of what is around them. The most useful step is still to offer a real refuge elsewhere.
My older cat settles in the tray: is it always arthritis?
No. Arthritis is common in older cats, but urinary trouble produces similar signs, and the Cornell Feline Health Center notes that these problems are more frequent in middle-aged, overweight and inactive cats. Only an examination can tell. Meanwhile, a tray with at least one low side and a warm, easy-to-reach bed make life simpler for them.
Key takeaways
- A cat sleeping in the litter tray should see the vet first: urinary problems and arthritis are the two causes to rule out.
- A cat straining to wee with nothing coming out needs a vet straight away, as an emergency, especially a male.
- Once health is checked, the tray often serves as a refuge for want of anything better: an enclosed bed in a quiet spot gives them another option.
- If another cat blocks the routes, choose a hiding place with two exits and one resource per cat, plus one extra.
