Important
Panting, collapse, vomiting, or weakness after heat exposure may be life-threatening. Move your cat to a cooler area and contact a veterinarian or emergency hospital immediately.
Overview
Cats are less likely than dogs to pant, so visible panting or distress in heat may signal a serious problem. Heat-related illness can occur in hot cars, poorly ventilated rooms, or during heat waves — especially for kittens, senior cats, or overweight cats. While moving to a cooler environment may help, veterinary evaluation is often needed to assess internal effects.
When emergency veterinary care may be appropriate
- Collapse, weakness, or inability to stand
- Open-mouth breathing or panting that does not improve in a cooler area
- Vomiting, diarrhea, or drooling
- Bright red, pale, or blue-tinged gums
- Confusion, stumbling, or seizures
- Your cat was in a hot car, enclosed space, or without shade and water
What to tell your veterinarian
- Estimated temperature and duration of exposure
- What symptoms you are seeing and when they started
- Whether your cat has cooled down and how
- Any water offered and whether it was kept down
- Your cat's age, weight, and medical history
What not to do
- Do not leave your cat in a parked car
- Do not assume cats tolerate heat better because they seem calm
- Do not delay veterinary contact if collapse or severe symptoms are present
- Do not rely solely on online cooling instructions without professional guidance
