Rapid / labored breathing
Has your cat's breathing become fast and labored?

Markedly rapid, labored or open-mouth breathing needs immediate veterinary contact. Causes differ; apparent coughing, one count or a webpage cannot rule out an emergency. Do not delay care for a video, count or form.
Possible medical causes
- Cardiomyopathy or heart failure can cause breathing problems, with no obvious early signs in some cats; age, a murmur or one count is not diagnostic.
- Asthma: can occur at any age and may be triggered by pollen, dust, smoke, or dusty litter; characterized by wheezing, coughing, and open-mouth breathing
- Lower respiratory infection: combined with coughing and reduced energy/appetite
- Other possible causes include fluid in the chest cavity, lung tumors, trauma, or airway obstruction
VCA gives a usual quiet-rest/sleep rate of 15–30 per minute and advises veterinary contact for persistent rates above 30; an individual threshold may be lower. Record only when calm and not purring as directed. Labored/open-mouth breathing or collapse must not wait for a count or be ruled out by a low number.
Initial at-home suggestions
- If you notice breathing difficulty, go straight to the vet — don't observe or try to manage it at home — excess stress can make symptoms rapidly worsen
- Before heading to the vet, keep your cat as calm as possible and minimize handling and stimulation (including loud talking or forcibly picking it up)
- If possible, count your cat's breathing rate while it's calm or sleeping and share it with your vet
- Record when the symptom appeared and whether there was an obvious trigger at the time (intense activity, a stressful event)
