Important
Open-mouth breathing, rapid breathing, or obvious respiratory distress in a cat may be life-threatening. Seek emergency veterinary care immediately.
Overview
Cats normally breathe quietly through their nose. Labored breathing, open-mouth breathing, extended neck posture, or rapid shallow breaths may signal a serious problem. Respiratory distress can progress quickly. Because cats often hide illness, visible breathing difficulty usually means the situation is urgent.
When emergency veterinary care may be appropriate
- Open-mouth breathing or gasping
- Rapid, shallow, or visibly labored breathing
- Blue or pale gums
- Collapse, weakness, or inability to settle
- Sudden onset after trauma, heat exposure, or possible toxin contact
- Breathing difficulty combined with lethargy or hiding
What to tell your veterinarian
- When breathing changes started and how they have changed
- Whether your cat is breathing through the mouth
- Any coughing, wheezing, or noise while breathing
- Recent stress, travel, or environmental changes
- Your cat's age, weight, and medical history
- Current gum color if you can check safely
What not to do
- Do not wait to see if breathing improves on its own
- Do not stress your cat further by forcing examination
- Do not assume mild panting after exercise is normal in cats — cats rarely pant
- Do not delay because your cat is still moving around
