How cold is too cold for cats? Taking yours out in winter

You can take your cat out in winter as long as the temperature doesn’t drop too low. So how cold is too cold for cats? Above 7°C, a healthy adult copes; below that, caution is called for, and under 0°C you skip the outing or cut it right down. Wind, rain and snow make everything worse. A kitten, an elderly or sick cat, or a short-coated cat should stay in.

At what temperature does a cat feel the cold?

A cat starts to feel the cold below 7 to 10°C. According to the French veterinary network Sevetys (in French), that’s the threshold below which a cat, especially one that stays outside for a long time, starts actively fighting the cold. Above it, a healthy adult with a good coat copes perfectly well with a short outing.

The real risk has a name: hypothermia, meaning a drop in body temperature. Again according to Sevetys, mild hypothermia begins when body temperature falls below 37.5°C, and becomes critical — a veterinary emergency — below 35°C. With a cat’s normal temperature at around 38 to 39°C, the margin is slim.

The principle to remember: it’s not a date on the calendar that decides, but the thermometer, the wind and your cat’s condition.

Below what temperature should you stop taking your cat out?

Below 0°C, it’s better to keep your cat indoors, or to limit the outing to a few minutes under supervision. Frost exposes the extremities — ears, paw pads, tip of the tail — to frostbite: according to PetMD, these poorly protected areas can freeze after prolonged exposure to sub-zero temperatures.

Above all, the temperature on the thermometer doesn’t tell the whole story. An icy wind, rain or snow bring the “feels like” temperature right down and soak the coat, which then loses its insulating power. At a windy, damp 5°C, a cat feels colder than at a dry, still 0°C.

The simple rule: in sub-zero, windy or wet weather, skip the walk and offer indoor play instead. At the other extreme, summer poses the opposite problem — see our guide to protecting your cat from the heat.

Which cats shouldn’t go out when it’s cold?

Some cats cope with the cold far worse than others. According to Sevetys (in French), the most vulnerable are kittens and older cats, short-coated (Siamese, Bengal) or hairless (Sphynx) cats, sick or convalescent animals, and indoor cats that aren’t used to the outdoors.

By contrast, breeds with a dense double coat — Maine Coon, Norwegian Forest Cat, Siberian — tolerate cold much better, without being immune to it. The table below sums up who can go out, and who stays in the warm.

An indoor cat discovering the outdoors finds the cold all the harder to handle because they aren’t used to it: winter isn’t the ideal season for their first outings.

A winter outing: short, but well supervised.

For those rare winter outings, a Pelux vest harness keeps your cat close to you, and its reflective strips make them visible when night falls early. Light and breathable, it comes off with a single clip when you get home, so you can dry your cat somewhere warm. Discover the harness →

Visibility becomes a real issue when night falls at five in the afternoon: a harness with reflective strips makes your cat easy to spot as soon as a light catches them.

How can you tell if a cat is cold?

A cat who is cold shows it through their body and behaviour: they shiver, curl up into a ball, fluff up their fur and look for a source of heat. According to Sevetys (in French), their extremities (ears, paws) become cold to the touch, they turn lethargic and may eat more to produce heat.

Signs to watch for during and after an outing:

• shivering, fluffed-up fur, body curled in on itself;
• ears and paw pads cold to the touch;
• a listless cat who drags themselves around or seeks out a radiator;
• cold nose, discharge from the eyes or nose once back home.

At these signs, go back in, dry your cat and warm them up gently (blanket, heated room). If the listlessness persists, call the vet: according to Santévet (in French), a chill can weaken a cat who is already vulnerable.

How to take your cat out safely in winter

If your cat loves the outdoors and the weather allows, a few rules make a winter outing safe. The idea isn’t to deprive them, but to adapt.

• Short and in daylight: a few minutes during the mildest hours (around midday), never at dusk when the cold sets in.
• Dry: avoid rain, snow and frozen ground; a wet coat no longer insulates.
• Visible: night falls early in winter — a harness with reflective strips helps drivers spot your cat.
• On a lead: a vest harness and its lead keep your cat close to you, away from icy roads and other dangers.
• Dried off afterwards: wipe their paws and fur, check their paw pads, warm them up in a heated room.

Watch their paws in town: road salt and antifreeze dripping from cars are irritating, even toxic — rinse the paw pads when you get home. These traps are among the outdoor dangers to know about all year round. To equip your cat properly, our guide to choosing a harness covers the criteria, and a secure outdoor space remains the best option for a cat who feels the cold.

Frequently asked questions

Can an indoor cat go outside in winter?

Yes, but with great caution: an indoor cat isn’t used to swings in temperature and gets cold quickly. Keep to very short outings, above 0°C, in dry weather and supervised on a harness — and don’t hesitate to call it off if they’re shivering or want to go back in. Winter isn’t the season to introduce them to the outdoors.

Should you put a coat on your cat for winter?

Rarely useful, and often badly received. Most cats cope poorly with clothing, which stresses them and hampers their movement; a healthy coat already insulates well. A shorter outing is better than a coat. A hairless cat (Sphynx) or a very old cat may be an exception, but even then the real answer is mostly to limit their exposure to the cold.

Are snow and road salt dangerous for paws?

Yes. Little balls of ice can form between the paw pads and bother your cat, and road salt, like antifreeze, irritates the skin and is toxic if they lick their paws. After every winter outing in town, wipe and rinse the paw pads with lukewarm water, then dry them.

My cat is asking to go out and it’s freezing: what should I do?

Don’t give in to extreme cold. Redirect their energy indoors: play sessions, hunting games, a scratcher, a lookout post by a sunny window. Most cats give up of their own accord as soon as they feel the biting cold under their paws; a two-minute outing is often enough to settle them.

Key takeaways

• Taking your cat out in winter is still possible above 7°C for a healthy adult; below 0°C, skip it or cut it right down — wind and damp make the cold worse.
• Hypothermia is the danger: according to Sevetys, a cat’s body temperature shouldn’t fall below 37.5°C (35°C = veterinary emergency).
• Kittens and older, sick, short-coated or hairless cats don’t go out when it’s cold; double-coated breeds cope better, without being immune.
• Short, dry, daytime outings on a reflective harness; dry your cat and rinse their paws (salt, antifreeze) when you get home.
