Yes, cats can survive some cold, but they are at real risk once it gets near freezing, especially without shelter. Healthy, well-adapted outdoor cats cope better than indoor pets, but no cat is truly “winter-proof.”
How much cold cats tolerate
Most sources agree that cats start to be at risk when temperatures fall below about 45°F (7°C), especially with prolonged exposure. Once it reaches freezing or below (32°F / 0°C), the risk of hypothermia and frostbite becomes high, and cats should be kept indoors or given proper insulated shelter.
Factors that affect survival
Cold tolerance depends on age, health, coat type, and whether the cat is used to being outdoors. Thin-coated, hairless, elderly, sick, or very young cats are much more vulnerable and should not be left out in cold weather.
Dangers of cold weather
In low temperatures cats can develop hypothermia and frostbite, which can be fatal if not treated. Cold stress can also weaken the immune system and worsen breathing problems or other chronic illnesses.
Signs your cat is too cold
Warning signs include shivering, lethargy, curling into a tight ball, seeking warm hiding places, and feeling cold to the touch. Pale or discolored ears, paws, or tail tips can suggest frostbite and need urgent veterinary attention.
How to keep cats safe
- Bring pet cats indoors when it is near or below 45°F (7°C), and always when it is at or below freezing.
- For outdoor or stray cats, provide a small insulated shelter, dry bedding (like straw), extra food, and unfrozen water in winter.
