Keep your cat in a cool, shaded place with fresh water, and bring them indoors when extreme heat is expected. Never leave a cat in a parked vehicle. If your cat is panting, weak, drooling, vomiting, struggling to breathe, disoriented, or collapsing, treat it as an emergency: move them to a cool area, gently apply cool—not cold—water, and contact a veterinarian immediately.

How to keep a cat safe in hot weather

Start with water, shade, and a cool place to rest. Heat can build up indoors as well as outside: a poorly ventilated, overheated apartment can put a cat at risk, too. The New York City Department of Health and Mental Hygiene notes that cats confined in poorly ventilated apartments may develop heat-related illness in its 2026 Veterinary Advisory #4.

  • Keep clean, fresh water accessible indoors and outdoors. Some cats may drink more from a running fountain, but it does not replace a clean, accessible water bowl.
  • Provide a shaded, cool resting area. If extreme heat is forecast, keep your cat inside in air conditioning if possible. Close blinds or curtains during the day and maintain airflow.
  • If your cat goes outside, make sure shade and water are available. Favor cooler morning or evening hours, and check sheds, garages, greenhouses, barns, and other outbuildings so a cat cannot become trapped inside.
  • Optional cooling aids include a cooling mat or a cool resting spot made with ice packs wrapped in blankets. Let the cat choose whether to use it; these do not replace a cool environment and water.

These measures reflect guidance from the Cornell Feline Health Center and VCA Animal Hospitals.

Who is more vulnerable to heat?

Flat-faced cats such as Persians, senior or overweight cats, and cats with respiratory, heart, or other underlying health conditions may be at greater risk. Ask your veterinarian what precautions are appropriate for your cat, especially if they have a chronic condition. The ASPCA’s hot-weather guidance and the NYC Health advisory discuss elevated risk in these groups.

How to tell if a cat is overheating

Cats may show subtler signs of heat stress than dogs, according to NYC Health. Panting in a cat is concerning and may signal difficulty breathing; do not assume it is normal or wait for more symptoms.

  • Excessive panting or difficulty breathing
  • Drooling
  • Weakness, unusual lethargy, or collapse
  • Vomiting or diarrhea
  • Bright red or dark red gums, or otherwise abnormal gum color
  • Disorientation

Heatstroke can become life-threatening quickly. If you see signs of possible heat illness, contact a veterinarian or emergency veterinary office promptly. Cornell’s heat safety guidance, UC Davis School of Veterinary Medicine, and NYC Health describe these warning signs.

What to do if you suspect heatstroke

  1. Move your cat to a cool, shaded place. If possible, choose an area with airflow.
  2. Gently apply cool water. Wet or spray the body with cool—not cold or ice-cold—water. Do not wrap or cover your cat in wet towels: NYC Health warns that covering an animal this way can trap heat. Sources differ on towel use, so avoid covering the cat and call a veterinarian for guidance.
  3. Call a veterinarian or emergency veterinary office immediately. Follow their instructions and arrange urgent care. Do not delay veterinary contact while trying home cooling measures.
  4. Offer cool water if your cat is alert and able to drink. UC Davis advises offering cool, not ice-cold, water. Do not force water into the mouth.

For possible heatstroke, home cooling is first aid—not a substitute for veterinary care. Cornell advises gently wetting the fur with cool water and contacting a veterinarian immediately; see its response guidance.

Prevent burns and other summer hazards

Hot pavement and paw-pad burns

Asphalt, concrete, sand, and metal can become much hotter than the surrounding air. NYC Health’s 2026 veterinary advisory reports these surfaces may be “40 to 60 degrees hotter than the air temperature”; that is a reported range, not a reading that applies to every surface or condition. UC Davis gives a practical check for pavement: if you cannot comfortably hold the back of your hand on it for seven seconds, it is too hot for a pet to walk on.

Keep cats off hot asphalt, wood, artificial turf, and other hot surfaces. For cats that go outdoors, favor grass or shade and cooler morning or after-sunset hours. Signs of paw burns include limping, reluctance to walk, redness or blisters, licking or chewing at the paws, and vocalizing when pressure is applied. Ask a veterinarian if you notice these signs. The hand test and burn guidance come from UC Davis and NYC Health.

Sun exposure and outdoor risks

Light-colored cats can be vulnerable to sunburn on exposed areas such as the nose and ear tips. Ask your veterinarian about sunscreen labeled for cats, and use it only according to the product label. Keep yard chemicals, hazardous plants, fireworks, and insect-repellent products away from cats; use only products labeled for animal use and follow their directions. The Cornell Feline Health Center and ASPCA provide further warm-weather precautions.

Vehicles and windows

Never leave a cat in a parked vehicle, even briefly or with the windows open. Heat can become dangerous quickly. Also secure window screens and do not leave unscreened windows open: cats can fall through them. See the American Veterinary Medical Association’s warm-weather safety guidance and the ASPCA’s safety tips.

Is there a safe temperature cutoff for cats?

The cited veterinary and public-health guidance does not establish a single cat-specific outdoor temperature that is safe for every cat. Heat risk depends on the cat and the conditions, including ventilation and access to a cool resting place. Do not use a temperature number as a reason to leave a cat in a hot or poorly ventilated space; provide shade, water, and a cool indoor option, and ask your veterinarian for advice tailored to your cat.
