Why do cats like boxes? What science says, and what to do about it
By Mila · Last reviewed October 2026
You spend an afternoon choosing a cat bed. It arrives, and your cat ignores the bed and climbs straight into the box it came in. Every cat owner has a photo of this moment.
It isn’t stubbornness. Why do cats like boxes so much? The short version: a box gives a cat three things it wants from a resting place. Walls to hide behind, a view of the room, and warmth. Researchers have tested the first one, and a fun study tested how little “box” a cat actually needs. Here’s what they found, and how to use it.
Why do cats like boxes? First, they feel safe
Cats are small hunters, and they are also prey for larger animals. A spot with walls around them and one way in means nothing can creep up from behind. From inside, they can watch the room without being seen.
A Dutch study by Vinke and colleagues, published in Applied Animal Behaviour Science in 2014, tested this with cats newly arrived at an animal shelter. Of 19 cats, 10 got a hiding box and 9 didn’t. Researchers scored their stress from video using a standard cat stress score. According to a Faunalytics summary of the study, the cats with boxes had lower stress and settled sooner than the cats without. The cats without boxes went looking for other places to hide.
A shelter is far more stressful than your living room. Still, the result fits what owners see at home. When something new happens, like visitors, a move or a new pet, the box is where many cats go.
Even an outline of a square works
In 2021, a team led by Gabriella Smith asked owners to test their own cats at home. They taped shapes on the floor. Some were real square outlines. Others were an optical illusion called a Kanizsa square: four Pac-Man shapes arranged so your brain sees a square that isn’t drawn.
As NPR reported, complete data came from 30 cats. They sat in the illusory square about as often as the real one, and more often than in a jumbled version of the same shapes. In other words, a cat may not need walls at all. A clear border on the floor seems to be enough to say “this is my spot”.
That’s why your cat also sits on a sheet of paper, a laptop or a folded towel in the middle of the floor.
Warmth and a good night’s sleep
Cats sleep a lot of the day, and a small enclosed space holds body heat. A box, a cave or a covered bed traps warm air around a curled-up cat, which is one reason these spots get busier in winter.
Cardboard also puts a layer between your cat and a cold floor, which matters on tiles in winter.
Curiosity, scent and a place to scratch
Boxes are new. They smell of somewhere else, they make interesting noises, and they’re a good place to ambush a passing ankle. Cats also rub their cheeks on the edges, leaving their scent, and some scratch or chew the cardboard. A new box quickly becomes a familiar one.
How to give your cat a box it will use every day
Cardboard does the job, but it gets soggy, chewed and flattened. If your cat loves boxes, give them a permanent version in the same spot.
- Choose walls and a roof. Cats who pick boxes usually want a covered space, not an open cushion.
- Give it a view. Place it where your cat can watch the room, such as a corner near where the family sits.
- Keep it low and quiet, away from the washing machine, the front door and the dog’s bed.
- Add something that smells of home. A worn T-shirt or their current blanket helps.
- Leave the box beside it for a few days. Let your cat compare, then take the box away.
Three box-style beds we stock
| Bed | Best for | What makes it box-like |
|---|---|---|
| Felt Donut Cat Cave | Shy cats and kittens up to about 4 kg | Thick felt walls, two openings, a hidden cushion |
| Cat Tent Bed with Cushion | Cats who like to watch from cover | A fabric tent on a frame, with a removable cushion |
| Foldable Cat House Bed | Cats who ignore open beds | A soft roof and walls, and it folds flat when you need the space |
If your cat sleeps in boxes on the floor, the felt cave is the closest match. If they like to sleep up high, a tent or house on a shelf or chair can work better.
When hiding means something else
Most box-loving is normal. But sudden changes matter. A cat who hides much more than usual or won’t come out for meals may be unwell or in pain. If that change is new, call your vet rather than putting it down to personality.
Questions about cats and boxes
Why do cats like boxes so much?
Boxes give cats walls to hide behind, a view of the room and a warm, enclosed place to sleep. A 2014 shelter study found cats with hiding boxes had lower stress and settled sooner. Curiosity and scent play a part too, because a new box smells and sounds interesting.
Do boxes really reduce stress in cats?
In one study of 19 newly sheltered cats, those given a hiding box had lower stress scores and adapted sooner than those without one. That was a shelter, not a home, but it matches what owners see: cats head for a box when visitors arrive or the routine changes.
Why does my cat sit in squares on the floor?
A 2021 at-home study found cats sat in an illusory square, made of four Pac-Man shapes, about as often as a real square outline. A clear border on the floor seems to be enough for a cat to treat it like a box. Paper, towels and laptops work the same way.
Should I leave cardboard boxes out for my cat?
Yes, if your cat enjoys them. Remove tape, staples and handles first, and throw the box out once it’s soggy or chewed. For a lasting option, a cat cave or covered bed in the same spot gives your cat the same sense of shelter.
Is it normal for my cat to hide all day?
Some cats are naturally shy and nap in hidden spots for hours. A sudden change matters more. If your cat hides far more than usual, stops eating or avoids you, it can be a sign of illness or pain. It’s worth a call to your vet.
Next time your cat chooses the box over the bed, you’ll know it’s not a comment on your taste. It’s a cat looking for walls, a view and a warm place to sleep. Give them a lasting version, and keep a cardboard box around for the days they want one.
