Just like people, cats can develop asthma. Known as feline asthma or allergic bronchitis, this long-term respiratory condition affects a cat’s airways and can make breathing difficult.
While feline asthma cannot be cured, the good news is that most cats can live happy, active lives with the right treatment and care.
This guide explains what feline asthma is, what causes it, how it is diagnosed and treated, and what to do if your cat has an asthma attack.
Feline asthma is a condition where a cat’s airways become inflamed, narrowed and overly sensitive. When exposed to certain triggers, the airways tighten and produce excess mucus, making it harder for air to move in and out of the lungs.
Asthma in cats is often linked to allergies in the environment, such as dust or pollen. Over time, repeated exposure can lead to worsening inflammation and, in some cases, serious or even life-threatening asthma attacks.
Feline asthma usually develops in young to middle-aged cats, most commonly between two and eight years old, and is often seen before the age of five. It appears to be more common in female cats and in certain breeds, including Siamese, Oriental and Himalayan cats, suggesting a genetic influence.
Some cats adopt a hunched posture with their neck extended during coughing episodes. In severe cases, breathing becomes visibly difficult, with the sides of the chest heaving in and out.
Snoring or loud breathing while resting is not always a sign of asthma, but any changes in breathing should be checked by a vet.
If your cat is struggling to breathe, breathing with their mouth open, or appears distressed, this could indicate an asthma attack.
Asthma attacks are medical emergencies and can be fatal if left untreated, so please contact your vet immediately.
Each cat may have different triggers, which is why identifying and reducing exposure is an important part of managing the condition.
There is no single test that definitively diagnoses asthma. Instead, vets diagnose feline asthma by ruling out other conditions that cause similar symptoms, such as heart disease, lungworm or respiratory infections.
Although asthma cannot be cured, it is usually manageable with long-term treatment. Most cats respond well to medication and ongoing care.
These reduce inflammation in the airways and are the cornerstone of asthma treatment. They are usually given daily and help prevent asthma attacks.
These medications relax and widen the airways, making breathing easier. They are often used alongside steroids, either regularly or during flare-ups.
The preferred method is via a pet inhaler, which delivers medication directly to the lungs and reduces side effects. Tablets, liquids or injections may be used in some cases.
It’s important to only use inhalers and spacers designed for pets, as human inhalers are not effective for cats.
Asthma attacks happen when the airways suddenly narrow, making breathing extremely difficult.
Reducing Asthma Triggers at Home
Managing your cat’s environment plays a major role in preventing flare-ups. You can help by:
Keeping a diary of asthma attacks can also be very helpful. Note the date, time, severity, possible triggers and any treatment given. Videos of coughing or breathing difficulties can be invaluable for your vet.
When to Contact your Vet
Contact your vet if:
You know your cat best. Even if symptoms don’t exactly match those described, always seek veterinary advice if you are concerned.
Long-term Outlook and Costs
Most cats with asthma do very well with treatment and enjoy a good quality of life. However, it is a lifelong condition and requires ongoing medication and check-ups.
If you’re able to, consider pet insurance while your cat is young and healthy to help with unexpected illness or injury. If your cat becomes unwell, talk openly with your vet about the options, the likely costs, and what feels manageable for you. Together, you can tailor a plan that’s right for your cat and your situation.
