Beds and Sleeping.

You know how this one goes. The bed arrives. It is beautiful: a soft grey donut in a bouclé that matches the sofa, photographed in a flat with better light than yours. You put it down. She walks past it, climbs into the cardboard box it was delivered in, turns round twice, and goes to sleep.

This is not a joke she is playing on you. It is a review. The box is warmer, firmer, smells of nothing, hugs her sides, and does not give her a static shock on the nose. The bed fails on all five counts and she has known this since she sniffed it.

Cats spend 12 to 16 hours a day asleep, sometimes more, and they are extremely good at it, which means they have strong views about where. This guide is about what those views are, why the bed you bought does not meet them, and how to spend the money once instead of four times.

A cat does not sleep in one long block. She sleeps in short bouts, often around an hour at a time, all day and all night, drifting from light sleep into deep sleep and then into brief spells of dreaming. Then round again.

The dreaming part, REM sleep, is where the twitching whiskers and the paddling paws happen, and cats do far more of it than we do: roughly a quarter to a third of their sleep, about three to four hours a day. It is also the part that needs a proper bed, for a reason that is slightly alarming when you first hear it. During REM, the brain switches off every muscle in the body except the eyes and the diaphragm. She is, for a few minutes at a time, completely limp. She cannot balance. She cannot brace. If the surface under her is narrow, soft, or wobbly, her head or a leg slips, the inner ear registers the movement, and she is jolted awake before the dream has finished.

So the loaf, the sphinx with paws tucked under, is for light sleep. She can be up and running in half a second from a loaf. Deep sleep and dreaming need the full side-lying sprawl, legs out, which only happens on a surface that is wide, flat, firm, and going nowhere. An adult cat stretched out needs 50 to 60 cm of continuous room.

Which means a bed that is too small or too squashy is not a slightly worse bed. It is a bed she cannot fully sleep in. She will nap in it and go elsewhere for the real thing. Usually your pillow.

This is the single most important thing in the guide, and almost nobody knows it.

A cat is comfortable, with no effort, at an air temperature of 30 to 38 degrees. That is her thermoneutral zone: the range where she neither shivers nor pants, and her body idles. It is a desert animal's setting. The average UK home in winter runs at around 18 to 20 degrees. To a shorthaired cat, your lovely warm living room feels roughly the way an 8 degree room feels to you in a t-shirt. Not dangerous. Just never quite right.

She has a few options. She can burn energy to stay warm, which she will do if she must. She can curl into a ball, which cuts the surface area she is losing heat through and tucks the thin bits, ears, nose, paws, into the warm bits. Or she can find somewhere that holds heat: a box, a radiator, your lap, the airing cupboard, the laptop, the one square of carpet the sun is on.

That is what she is doing when she chooses a bed. She is not assessing the fabric. She is assessing whether the thing will hold a pocket of 30 degree air around her for the length of a sleep cycle.

It matters most during dreaming. In REM sleep the body stops regulating its own temperature; no shivering, no fluffing up, nothing. She drifts towards the temperature of whatever is around her. If the bed cannot keep that pocket warm, she gets cold, wakes, and moves. If it keeps it too warm, which thick synthetic fur does, she overheats, wakes, and moves to the cold tiles. The mid-nap relocation you thought was a whim is thermostat behaviour.

The curl means she is cold. The sprawl, belly up, means she is warm enough. A bed that only allows one of the two is a bed for half the year.

It smelled of a factory. A cat has tens of millions of scent receptors, perhaps as many as 200 million, to your five million, plus a second organ in the roof of her mouth for the chemical signals you cannot detect at all. A new bed is polyurethane foam, glue, dye and polyester, vacuum-packed in plastic so that every volatile compound it has given off since the factory is trapped in the bag with it. When you open it, she gets the whole lot at once: formaldehyde, solvents, flame retardant. It is, to her, an object that reeks of nothing she has ever met and nobody she knows. Compare the laundry basket, which smells of you, and has never once been rejected.

It shocked her. Polyester sherpa, fleece and faux fur are the fabrics that photograph best and they are all, electrically, at the opposite end of the scale from cat hair. In a centrally heated British house in January, with the humidity on the floor, she steps into the bed, circles twice, and a charge builds between her coat and the fabric until it jumps. It goes to the wettest, thinnest bit of her: the nose, the ear, the pad. One spark. A cat does not need two. She has now learned that the bed bites, and she will not be back.

It swallowed her feet. The overstuffed look is achieved with loose polyester fibre, and loose fibre moves. A 5 kg cat puts her weight on a paw and the filling shifts sideways and she drops through to the floor. For an animal whose entire sense of safety is built on being able to launch off a surface instantly, that is not cosy. It is quicksand. It is one of the commonest reasons a bed is rejected. She steps in, the ground goes, she steps out, and the bed becomes a place where the floor cannot be trusted.

None of these are quirks. They are a sensory audit, and the bed failed it.

Wool and sheepskin. The best fabric there is for a cat to sleep on, and it is not close. Wool fibres have a natural crimp that traps millions of tiny pockets of still air, so it insulates like a duvet but breathes, so she does not overheat. It can absorb up to about a third of its weight in moisture in very humid air without feeling damp, which keeps the surface dry and the dust mites away. Because it holds that moisture, static cannot build on it; there is no spark. It carries a trace of lanolin, which cats like, and it soaks up her own facial scent and keeps it. Felted merino, shearling, a sheepskin offcut from a rug shop. Expensive, lasts for years, and washable if you are careful.

Cardboard. Free, and the only material that scores higher than wool with the cat herself. More on this below.

Firm foam. Not for the surface, for the base. A dense foam core, over 30 kg per cubic metre, spreads her weight so no hip or shoulder presses on the floor, and it does not move under her feet. Essential for cats over ten, most of whom show joint changes on X-ray whether anyone has noticed or not. It needs a breathable cover or it sweats.

Cotton canvas and linen. Fine. Breathable, no static, washable, holds scent. Not warm on its own, so they want a wool or foam layer underneath.

Polyester sherpa, fleece and faux fur. The fabrics every bed is made of because they look soft in the photo and take dye well. They do not breathe, so she overheats in deep sleep. They cannot absorb moisture, so the surface goes clammy. They generate static in winter. They mat flat in months. Cheap, and the price is the only argument for them.

Loose polyfill. The stuffing. Shifts under her, lumps into hard knots, goes thin where she lies, cold where the seams press. The marshmallow problem, in a bag.

The donut. A flat centre with a raised rim all the way round. The rim does two jobs: it blocks the draught that runs along every floor, and it gives her something to rest her chin on, so she can keep an eye on the room without holding her own head up. Cats also like to press their spine against something solid when they sleep; it is the feeling of a littermate. The rim has to be firm for that to work. An underfilled rim folds outwards when she leans on it, and then it is just a cushion with a lip.

The cave. Igloo, pod, hooded bed. Covers the back, sides and top, cuts the light, muffles the house, and traps her body heat in a small chamber. The right answer for a nervous cat and the wrong answer in July, when the inside of a fabric cave can get uncomfortably hot and she will not go near it. The felted wool pods that can be pushed down into an open bowl for summer solve this; the rigid plastic igloos do not.

The hammock. Suspended fabric, on a frame or clipped to a cat tree. No hard contact points, so her weight spreads evenly across her whole side, which old and bony cats appreciate. Air moves underneath, so it does not overheat. It does move slightly, which some cats will not tolerate.

The radiator cradle. Hooks over the radiator and sits her directly in the warm air rising off it. In a cold British house this is as close to her thermoneutral zone as she will get without a lap, and most cats would live in one. Two cautions. A radiator panel can exceed 60 degrees, and a cat who sleeps pressed to it for hours can get a heat rash or a burn on the thin skin of her belly, so the cradle needs a thick insulated base or a wooden back between her and the metal. And hot air dries her out, so water needs to be nearby. Never use a heat pad without a thermostat, or leave one on unattended.

The flat pad. No rim, no roof, just a wide firm mattress. The only shape that lets a cat fully sprawl, which makes it the right one for the confident, warm, floor-lounging type, and for any cat on a warm day. Useless to a cat who wants walls.

The box is not a joke. The box is the reference design.

Researchers at Utrecht University gave half the cats arriving at a shelter a cardboard box and the other half nothing. Within three or four days the cats with boxes had measurably lower stress scores than the cats without, on a validated scale. That is a free object outperforming the entire pet bed industry in a controlled study.

Here is why. Corrugated cardboard is a wave of paper sandwiched between two flat sheets, and every flute in that wave is a sealed pocket of air. It is a surprisingly good insulator. When she curls up inside, her body warms the air in the box in minutes, the walls stop it leaving, and she is sitting in a 30 degree microclimate in an 18 degree room. It is a thermos with a cat in it.

Then there is the squeeze. Many cats like to feel walls against them. A box that is slightly too small presses on her back, her flanks and her chest all at once, and many cats seem to settle better when they are snugly enclosed like this. A soft bed cannot do this. Its edges give way when she leans. A box does not give. That is the point of it.

And it smells of nothing. No foam, no glue, no dye. Plain cellulose that takes her scent within an hour and then smells of her.

If you want to know what she wants in a bed, it is this: a firm floor, walls that touch her, a roof if she is shy, air that stays warm, no smell, no shock. Everything in this guide is a way of buying a box that lasts longer than a box.

Spend five days watching where she sleeps when nobody has bought her anything. She will tell you the whole specification.

Where. Four types, and most cats are clearly one of them.

The tree dweller sleeps on top of the wardrobe, the kitchen cupboards, the bookcase. She wants to be above your eye line with a view of the whole room. A bed on the floor will never be used, however good it is. She needs a basket with a lip on a high shelf, a wall perch, or the top of the tree.

The bush dweller sleeps under the coffee table, behind the sofa cushion, beneath the chair. Floor level, hidden, with a gap to peer through. A high donut with a firm rim, tucked somewhere low and out of the walkway.

The cave dweller goes further: inside the wardrobe, in the drawer you left open, under the duvet. She wants a roof. A felted wool pod or a hooded bed, in a quiet corner, with two ways out if there is another cat in the house.

The beach dweller sleeps in the middle of the rug, belly up, in everyone's way. She does not want walls; walls get in the way of the sprawl. A big flat firm pad, somewhere warm and central.

How. The curl or the sprawl. A cat who mostly curls wants a bowl or a box. A cat who mostly sprawls wants 55 cm of flat. Many cats do both depending on the temperature, in which case the answer is one of each.

Age. Over ten, assume arthritis. She needs a firm foam base she can get up from, not a soft one she sinks into, an entry step no higher than 5 cm, and the bed within a metre and a half of where she already spends the day, because a stiff cat will not cross a cold room for a nicer bed.

The British floor problem. Most older UK houses, the Victorian and Edwardian terraces, the thirties semis, have suspended timber ground floors: boards on joists over a void that is deliberately ventilated to the outside through air bricks. In winter that void is at outdoor temperature, and the air comes up through the gaps between the boards, round the radiator pipes and behind the skirting. Your thermostat, at head height, says 21 degrees. The bottom 15 cm of the room, where the cat bed is, can be several degrees colder. A bed on the floor in that house is a bed in a draught, and no amount of wool fixes a draught from underneath.

The fix is height. Lift the bed at least 30 cm: a low table, a bench, a sturdy box, the bottom shelf of a bookcase. If it must be on the floor, put something between it and the boards: a closed-cell foam mat, a folded wool rug, anything that breaks the cold.

Windowsills are wonderful while the sun is on them and cold the moment it leaves, because the glass cools the air next to it and it sinks straight onto the sill. A window bed wants a high back against the glass and an insulated base against the stone.

Sightlines. A cat sleeps best with her back to a wall and a view of the door. Not in the hallway, not next to the washing machine or the boiler, not in the path of the front door draught. Somewhere she can see you coming before you arrive.

Two cats. One more sleeping place than you have cats, in different rooms, out of each other's line of sight. A cave with one entrance can become a trap if the other cat sits in the doorway, which she will; choose caves with two openings, or open donuts. Cats who are bonded will sleep in a pile. Cats who merely tolerate each other should never be expected to share a bed, and the one who ends up on your pillow is usually the one who lost.

Air it first. Unpack the bed in the spare room or on a landing and leave it there for two or three days with the window open. The factory smell has to go before she meets it. If it still smells of anything to you, it is overwhelming to her.

Put it where she already sleeps. Not where you would like her to sleep. On the sofa cushion she has claimed, on the windowsill she uses, on the chair that is covered in her fur. The bed inherits the location's approval. Once she is using it, you can move it, a little at a time, somewhere you can live with.

Make it smell of home. Line it with something unwashed: the jumper you wore yesterday, the blanket off the sofa. Then take a soft cloth, rub it gently along her cheeks, and wipe it round the rim. Her own scent on the edge is the signal that this has already been inspected and passed.

Do not put her in it. This is the whole rule. A cat lifted and placed into a bed has been placed into a trap by someone she trusted, and will treat the bed accordingly. She finds it, or she does not. Treats inside help. Patience helps more. Lilou took eleven days to accept a sheepskin and now will not be parted from it. Felix, who is a guinea pig and therefore sensible, took four minutes.

Wash the cover, not the scent. A removable cover on a cool wash keeps the fleas and dander down. Washing the whole bed, with the base, strips every trace of her from it and you are back to day one. One cover on, one in the wash, and rotate.

Sleep is the most honest thing a cat does. A cat who has always slept on the windowsill and moves to the airing cupboard is cold, or the house is. A cat who stops climbing to the wardrobe is telling you about her hips before any vet will. A cat who sleeps curled every day in a warm room, or who starts sleeping somewhere she can be found easily, is worth a closer look.

Log where she sleeps and how in the Maleb's Tracker. The location, the posture, the time of day. The pattern is the baseline, and the change is the signal.

She will sleep where she decides. The job is not to overrule her. It is to read the decision, and then build her a better box.

A sudden change in where or how much your cat sleeps, especially in an older cat, is worth a conversation with your vet.
