How to Prevent Heatstroke in Cats

1 Causes of Feline Heatstroke

In summer, long exposure to heat disrupts a cat’s temperature regulation and drains electrolytes, leading to circulation failure and organ damage. Poorly ventilated or high-rise indoor spaces can exceed 36°C, the upper limit of a cat’s thermal comfort zone (30–36°C).

2 Symptoms of Heatstroke

Unlike dogs, cats sweat only from the mouth and paw pads. When hot they stretch out to expose the pads and secrete sweat (and pheromones), leaving damp paw prints vets call ‘oily paws.’

They also cool by licking their fur, using saliva evaporation — a method dogs lack, since cats descended from African wildcats of hot, dry regions.

When that isn’t enough, a cat pants, exhaling heat and drawing in cool air — a sign it is nearing heatstroke.

If the air stays hot, panting can’t shed heat and instead causes rapid water loss and exhaustion, then dehydration. Signs appear: rising temperature, dry nose, red conjunctiva and gums, and in severe cases seizures and coma. Cool the cat and get to a vet at once, or heatstroke can be fatal.

3 Prevention

Control indoor temperature with AC, fans, or ventilation.

Offer plenty of low-salt cool water so the cat loses heat through sweating, urination, and panting while replenishing fluids and electrolytes.

Provide large tiles or a cooling mat to slow temperature rise.

Trim the fur between the paw pads so sweat evaporates promptly.

4 Treatment

At the first signs, move the cat to shade and lay a cool wet towel over it to lower surface temperature. If it is conscious and can swallow, syringe or spoon a little salt water to maintain fluids.

If seizures or coma occur, don’t treat at home — go to a vet. On the way, keep a cold towel or ice pack on the forehead and back of the neck to protect the brain from heat damage.
