Most healthy indoor cats handle winter well if they can choose where to sleep, because a cat is an expert at finding the warmest cushion in the house. Problems appear at the edges: draughty floors, unheated rooms at night, and beds placed where people think a cat should sleep rather than where the cat actually settles. Cosiness is mostly about removing those cold edges.
Raise beds off cold floors and out of the draught line
Floors are the coldest layer of any room, and a thin mat on tiles or boards loses heat all night. Put your cat's main bed on a low platform, a rug, or a piece of furniture, and line it with a blanket that can hold a curled cat's body warmth. Check the spots your cat already favours for draughts from doors, windows, and letterboxes, and move bedding a short distance sideways out of that airflow rather than across the house to a spot your cat ignores. A box with high sides and one entrance traps warmth better than a flat cushion in an open room, which is why so many cats choose the box over the expensive bed.
Use household heat safely and let your cat decide
A bed near, not against, a radiator lets your cat enjoy radiant warmth without lying on a hot surface. Never leave a cat alone with an exposed heater, an open fire without a guard, or a heated pad that has no safe low setting and no space to move off it, because a sleeping cat can stay too long on a surface that is too hot. Sun patches are valuable winter heating: open curtains in the room your cat uses by day so a sunlit chair or windowsill can do the warming for free. In the evening, when heating drops, some cats appreciate a microwavable heat disc under a blanket in their bed, provided it has cooled to gentle warmth and your cat can leave it freely. Choice is the safety feature in every one of these options.
Adjust food, play, and coat care for the season
Indoor cats often move less in winter and graze more, so keep play sessions in the routine to protect waistlines and mood rather than simply adding extra food for the cold. A short game before the evening meal warms muscles and helps your cat settle into its bed afterwards. Brush regularly, because a matted coat insulates poorly; mats lift the fur away from the skin and let cold air in. Long-haired cats benefit from particular attention behind the ears and under the collar where winter coats tangle. Keep water fresh and not icy, and consider moving a bowl away from a cold external wall, since cats drink less from water that feels unpleasantly chilly, and hydration matters to winter health as much as warmth does.
Give extra thought to older, thin, and unwell cats
An older cat with stiff joints may struggle to climb to a high warm perch, so bring the warmth down: a low, firm, well-padded bed in the warmest quiet room beats a lofty spot your cat stops using. Thin cats, very young kittens, and cats recovering from illness lose heat faster and deserve the first claim on the best bed and a lower threshold for concern. Persistent shivering, cold ears that do not warm up indoors, unusual sleepiness, or going off food during a cold snap are reasons to contact a vet rather than simply adding another blanket. With the cold edges removed, most cats settle into a contented winter rhythm of sun patch, warm bed, and brief lively intervals.
