Why Is My Cat Breathing Fast? Causes, Signs, and When to Worry

Common causes of rapid breathing in cats

• Feline asthma: Causes difficulty breathing, rapid breathing, wheezing, and coughing. Symptoms can be triggered by allergens like dust, smoke, or certain foods.

• Upper respiratory infections: Highly contagious viral or bacterial infections causing sneezing, nasal discharge, and rapid breathing. Common in shelters and multi-cat households.

• Stress or anxiety: Can lead to increased respiratory rate. Common in new environments or during changes in routine.

• Heart conditions: May cause rapid breathing as the body tries to compensate for reduced oxygen.

• Obesity: Excess weight can put pressure on the lungs, leading to faster breathing.

Signs to watch for

• Breathing rate over 40 breaths per minute while resting or sleeping
• Open-mouth breathing or panting
• Coughing or wheezing
• Blue lips or gums (indicates lack of oxygen)
• Hunched posture with neck extended

When to seek veterinary care

• Immediate emergency: If your cat is struggling to breathe, has blue lips/gums, or is breathing with an open mouth

• Urgent care: Breathing rate consistently over 40 breaths per minute at rest

• Schedule an appointment: Persistent coughing, wheezing, or nasal discharge lasting more than a few days

Potential diagnoses and treatments

Feline asthma

• Diagnosed through physical examination, chest X-rays, and possibly allergy tests
• Treated with corticosteroids to reduce inflammation and bronchodilators to open airways
• Removing allergens from the environment can help prevent attacks

Upper respiratory infections

• Often caused by feline herpesvirus or calicivirus
• Treatment may include antibiotics for secondary bacterial infections, supportive care, and in some cases, antiviral medications
• Vaccination can help prevent some common respiratory infections

Prevention and management

• Regular vet check-ups: To catch and treat respiratory issues early
• Maintain a healthy weight: Obesity can exacerbate breathing problems
• Reduce stress: Provide a calm environment and consistent routine
• Use low-dust litter: To minimize airborne irritants
• Avoid smoking and use of aerosol sprays around your cat
