My senior cat is having a hard time breathing - is this serious?

Laboured breathing in cats is always a medical emergency. Unlike humans, cats should never need to visibly work to breathe. Any visible effort - open-mouth breathing, neck extended to breathe, belly pumping with each breath, or blue-tinged gums - indicates severe respiratory compromise.
Act immediately
Do not wait or try to monitor at home. Transport your cat to an emergency vet as calmly and quickly as possible. Keep them in a carrier in a cool, well-ventilated area. Minimise handling - the stress of being held can worsen respiratory distress significantly.
Common causes in senior cats
- Congestive heart failure (CHF): Fluid accumulates in or around the lungs (pleural effusion), making breathing increasingly difficult. Hypertrophic cardiomyopathy (HCM) is the most common heart disease in cats.
- Pleural effusion: Fluid around the lungs - can result from heart disease, lymphoma, infection, or chylothorax.
- Feline asthma: Can present as sudden breathing crises, often with a characteristic 'hunkered down' posture and neck extended forward.
- Pneumonia: Bacterial, viral, or aspiration pneumonia
- Pulmonary cancer: Primary or metastatic tumours can compromise lung capacity.
- Anaemia: Severe anaemia (from kidney disease, for example) causes the body to breathe faster to compensate for reduced oxygen-carrying capacity.
Treatment depends on the underlying cause but may include oxygen therapy, draining fluid, diuretics, bronchodilators, or antivirals. Early emergency intervention dramatically improves outcomes.
