Cats cope with heat by seeking cool surfaces and doing very little, so your job in a heatwave is to make that strategy easy indoors. A cat sprawled on bathroom tiles, stretched out rather than curled, and drinking more than usual may be managing perfectly well. Trouble starts when the whole home stays hot, water goes stale, and the cat has nowhere genuinely cooler to retreat to.
Build one properly cool room instead of cooling everywhere a little
Choose the room that naturally stays coolest, often a north-facing room or one with tile or stone flooring, and make it your cat's heatwave base. Close curtains or blinds before the sun hits the windows, because shutting heat out early beats trying to shift it later. A fan can move air across the room but should not be the only measure, and it should never be aimed so your cat has no escape from the draught. Keep the litter tray, water, and a cardboard box or low bed in that room so your cat does not have to cross hot parts of the home for essentials. If different rooms heat up at different times of day, follow the shade and move the water and bedding with it rather than expecting your cat to relocate a favourite hot spot alone.
Make water easy, fresh, and hard to knock over
Put water in several heavy bowls in the rooms your cat actually uses, and refresh them more often than usual because warm, dusty water puts cats off drinking. Some cats drink better from a wide bowl that does not brush their whiskers, and many prefer water placed away from food. Ice cubes in a bowl give some cats something cool to investigate, but treat them as an extra rather than the main supply. If your cat eats wet food, serving it during a heatwave adds moisture to the day without a battle. Note roughly how much drinking is happening: a cat that stops drinking in hot weather is a concern even before other signs appear.
Slow the day down and groom the coat out
Move play sessions to the coolest hours and keep them gentle, because an enthusiastic evening chase in a hot flat can undo a day of careful cooling. Brush short sessions into the routine to lift loose undercoat that traps warmth, stopping if your cat finds handling stressful in the heat. A towel dampened with cool water and laid on the floor lets your cat choose contact with something cooler; never wrap a hot cat tightly or use freezing water, which can distress rather than help. Leave sleeping cats alone in the middle of the day, keep visitors and children from repeatedly picking them up, and postpone non-essential car trips, since a parked or stuffy vehicle heats far faster than your living room.
Recognise overheating early and act fast
Panting is uncommon in cats and should always be taken seriously in hot weather. Drooling, restlessness followed by unusual dullness, wobbling, vomiting, bright red gums, or a cat that seems confused or cannot settle all point to a cat that needs urgent veterinary help. Move the cat to the coolest room you have, offer water without forcing drinking, and contact a vet straight away for instructions rather than experimenting at home. Kittens, older cats, overweight cats, and flat-faced breeds can struggle sooner, so lower your threshold for calling if your cat fits one of those groups. A little preparation keeps most indoor cats comfortable through a hot spell.
