Heat safety for cats — the quick answer
✓ Never leave a cat in a parked car
✓ Provide shade, airflow and several water sources
✓ Panting or collapse in heat is an emergency
✓ Cool gradually while travelling to care
Cats can overheat in hot, poorly ventilated spaces, cars, sunrooms and enclosed balconies. Flat-faced, elderly, very young, overweight and ill cats may be at greater risk.
Prevent heat build-up
Keep the cat in the coolest ventilated rooms, close blinds before direct sun, provide shade and fresh water, and check enclosed balconies, sheds and conservatories.
Recognise danger
Panting, drooling, bright or abnormal gums, weakness, vomiting, confusion, collapse or seizures after heat exposure requires emergency veterinary care.
What to do
Move the cat to a cooler area, call an emergency clinic and begin gentle cooling with cool—not ice-cold—water or damp towels while arranging immediate transport. Follow the clinic's directions.
Plan for vulnerable cats
Ask your veterinarian about an individual hot-weather plan if your cat has heart, lung or airway disease. Check indoor temperature rather than assuming the home stays cool.

Airflow may help, but it is not enough in a dangerously hot room. Provide shade, water and access to a genuinely cooler area, and monitor vulnerable cats closely.
