Cats can tolerate only a limited amount of cold, and many get uncomfortable sooner than people expect. Healthy adult cats cope best, but prolonged exposure to low temperatures can quickly become dangerous.
General temperature limits
Most sources agree that temperatures below about 7–10°C (45–50°F) start to feel uncomfortably cold for many cats, especially over time. At around 0°C (32°F) and below, the risk of frostbite and hypothermia rises sharply for all cats if they stay outside without proper shelter.
Factors that change tolerance
Cold tolerance depends on age, health, body condition, and coat type. Kittens, seniors, thin or sick cats, and short‑haired or hairless breeds get cold faster than healthy adult long‑haired cats such as Maine Coons or Norwegian Forest Cats.
Safe indoor range
Veterinary and welfare guidelines suggest most cats are comfortable roughly between about 10°C and 26.5°C (50–80°F). Elderly cats or those with short coats or certain illnesses may need the cooler end of that range avoided and benefit from extra warm resting spots even indoors.
Warning signs of cold stress
Common signs that a cat is too cold include shivering, curling up tightly, seeking warm hiding places, lethargy, and feeling cold on ears, paws, or tail. More severe cold exposure can lead to hypothermia and frostbite, which are medical emergencies and can be life‑threatening without prompt veterinary care.
Practical advice
As a rule of thumb, do not leave pet cats outside for long when air temperatures are below about 7°C (45°F), and keep them indoors when it is at or below freezing. Provide dry, draft‑free, well‑insulated shelter, bedding, and access to food and unfrozen water for any outdoor or community cats during cold weather.
