Your cat crouches low, stretches their neck and makes a repeated hacking sound. You expect a hairball to appear – but nothing comes out. Then they walk away as though nothing happened.

It is easy to dismiss an occasional episode, especially when your cat seems comfortable afterwards. However, repeated “hairball attempts” may actually be coughing, and coughing deserves veterinary attention.

Feline asthma is an inflammatory disease that narrows the lower airways, making breathing more difficult. Vets investigate it through your cat’s history, examination, chest imaging and, in selected cases, airway sampling. There is no single test that confirms every case.

The first priority is determining whether your cat is stable enough for testing. Open-mouth breathing, obvious effort to breathe, collapse or blue-grey gums require immediate emergency veterinary care. Do not wait to identify the cause at home.

What Is Feline Asthma?

Inside your cat’s lungs, branching airways carry air towards the areas where oxygen enters the bloodstream.

With asthma, inflammation makes these airways unusually sensitive. The muscles around them can tighten, the lining can swell, and mucus can further restrict airflow. This combination may cause coughing, wheezing or difficulty breathing.

Some cats have intermittent episodes. Others develop persistent signs or a sudden severe attack.

Asthma is generally a long-term condition requiring management. A cat appearing normal between episodes does not necessarily mean the underlying airway inflammation has disappeared.

What Are the Signs of Asthma in Cats?

The most noticeable sign may be a cough that comes and goes. Pet parents sometimes describe it as gagging, retching or trying unsuccessfully to bring up a hairball.

Possible signs include:

• Repeated coughing or hacking.
• Wheezing or noisy breathing.
• Crouching with the neck extended during an episode.
• Increased breathing effort.
• Reduced tolerance for play or activity.
• Episodes of rapid breathing.
• Open-mouth breathing during significant distress.

These signs do not confirm asthma. Several respiratory conditions can look similar, which is why treatment should follow an assessment rather than an assumption.

Is It a Hairball or a Cough?

Vomiting a hairball usually involves retching and may produce hair, food or fluid. A coughing cat may crouch, extend their neck and repeatedly expel air without producing anything.

The distinction is not always clear from sound or posture alone. A short video is often useful-but only if your cat is breathing comfortably enough that recording will not delay care.

Repeated episodes without a hairball should not automatically be treated with hairball remedies.

When Is a Cat’s Breathing an Emergency?

A cat struggling to breathe needs urgent help, whether the cause is asthma, heart disease or something else.

Seek emergency care for:

• Open-mouth breathing at rest.
• Pronounced abdominal effort with each breath.
• Inability to settle because of breathing difficulty.
• Blue-grey gums or tongue.
• Collapse or severe weakness.

Do not force open your cat’s mouth to inspect the gums if doing so causes stress. Call the hospital, minimise handling and transport them in a well-ventilated carrier without compressing the chest.

Do not give food, water, human cough medicine or an unprescribed inhaler during breathing distress. Follow an existing veterinary rescue plan if your cat has one.

Breathing difficulty is a clinical sign with several possible causes; emergency treatment must address the actual problem.

Why Vets May Stabilise a Cat Before Taking X-Rays

It can feel worrying when the veterinary team provides oxygen before explaining exactly what is wrong. However, a distressed cat may not tolerate restraint or positioning for imaging.

The safest sequence may be to support breathing, reduce stress and perform a limited assessment before proceeding with further tests.

This does not mean the investigation has stopped. It means the team is choosing the order of care according to your cat’s condition.

Once breathing is more comfortable, a fuller examination and diagnostic plan become safer.

How Do Vets Investigate Feline Asthma?

The investigation combines several pieces of evidence. Each test answers a different question, and none should be interpreted in isolation.

1. Understanding the Episodes

Your vet will ask when the coughing started, how often it happens and whether it has changed.

Useful details include:

• Whether episodes follow play, cleaning or litter-box use.
• Whether your cat is comfortable between episodes.
• Outdoor access and parasite prevention.
• Previous illnesses and medication.
• Exposure to smoke, sprays or dusty environments.
• Appetite, energy and weight changes.

These questions help distinguish a recurring airway problem from infection, parasites or another illness.

You do not need to identify a trigger before booking an appointment. Many cats do not have an obvious connection between an exposure and an episode.

2. Examining the Chest and Breathing Pattern

The vet observes breathing rate, effort and posture, then listens to the chest when it is safe to do so.

Wheezing may support suspicion of narrowed airways. However, an examination alone cannot reliably confirm asthma, and a cat may have fewer obvious findings between episodes.

Your description and video can therefore be important even when your cat looks comfortable in the consultation room.

3. Taking Chest X-Rays

Chest X-rays help assess the lungs, airways, heart outline and space around the lungs.

In cats with asthma, images may show thickened airway markings or overinflated lungs caused by trapped air. X-rays can also reveal findings that suggest a different problem.

However, an X-ray does not automatically prove or exclude asthma. Some cats have subtle changes, and several diseases produce overlapping patterns.

The vet interprets the images alongside the symptoms and other results rather than relying on one visual feature.

4. Checking for Other Illnesses

Blood tests may assess general health and provide clues about inflammation or other conditions. They also help with planning if sedation or anesthesia is being considered.

An increase in eosinophils—a type of white blood cell associated with some allergic and parasitic conditions—may be relevant. It does not establish an asthma diagnosis by itself.

Additional testing depends on your cat’s history, examination and imaging.

What Other Conditions Can Look Like Feline Asthma?

A careful diagnosis matters because treatments appropriate for asthma may not address another disease.

Possible condition	Why the vet considers it
Chronic bronchitis	Can cause a similar persistent cough
Lungworm or other parasites	Can cause airway inflammation and respiratory signs
Pneumonia	Infection can cause coughing and breathing difficulty
Heartworm-associated respiratory disease	May resemble inflammatory airway disease
Heart disease or fluid around the lungs	Can cause rapid or laboured breathing
Masses or foreign material	May obstruct or irritate the respiratory system

The list does not mean every coughing cat needs every available test. It explains why the vet may investigate beyond asthma before settling on a treatment plan.

Why Might a Stool Sample Be Needed?

Lungworm may seem unrelated to a fecal test, but some parasite stages can be detected in feces.

Your vet may request a particular test or several samples. A routine parasite screen does not detect every respiratory parasite equally well.

The choice depends on exposure, prevention history and local disease considerations.

What Is Bronchoalveolar Lavage?

Bronchoalveolar lavage, or BAL, collects a sample from the lower airways for laboratory examination.

Under anesthesia, a small amount of sterile fluid is introduced into an airway and recovered. The sample can be examined for inflammatory cells, organisms and other abnormalities. Culture may help investigate bacterial infection.

Sometimes sampling is performed with bronchoscopy, which uses a small camera to examine the airways.

What Can the Sample Tell the Vet?

A sample containing increased eosinophils may support asthma in the right clinical setting. However, parasites and other conditions can also produce eosinophilic inflammation.

Sampling can help distinguish inflammatory patterns and identify disease that would require a different treatment.

Does Every Cat Need BAL?

No. Airway sampling carries anesthetic and respiratory risks, so the vet weighs the likely benefit against your cat’s condition.

It may be particularly useful when findings are unclear, infection is suspected or treatment is not working as expected. A cat in significant respiratory distress generally needs stabilisation before an elective invasive investigation.

Can Allergy Tests Confirm Cat Asthma?

Not reliably on their own.

A positive allergy result does not prove that a particular substance caused your cat’s coughing. Likewise, failure to identify an allergen does not exclude asthma.

Allergy testing may have a role in selected cases, but it does not replace investigation of respiratory signs.

How Is Feline Asthma Treated?

Treatment usually addresses two problems: airway inflammation and airway narrowing.

Veterinarians commonly use corticosteroids to control inflammation. Bronchodilators may be prescribed to relax tightened airway muscles.

These medicines serve different purposes. A bronchodilator can help airflow, but it does not replace treatment of underlying inflammation.

Some cats receive inhaled medication through a feline mask and spacer. Others need oral or injectable treatment, particularly during initial management. The plan depends on severity and how well the cat tolerates treatment.

Do not adjust or stop medication because coughing has improved without discussing it with your vet. Antibiotics are not routine asthma treatment unless there is evidence of a bacterial problem.

What Can You Change at Home?

Reducing airborne irritants can support care, although environmental changes do not replace prescribed treatment.

Consider:

• Keeping the home free of tobacco and vaping smoke.
• Avoiding incense and unnecessary aerosol sprays around your cat.
• Choosing a low-dust, unscented litter.
• Moving your cat away from rooms during dusty cleaning.
• Avoiding strong fragrances and scented products near resting areas.
• Maintaining ventilation without exposing your cat to heavy outdoor smoke.

You do not need to change everything at once. Discuss likely exposures with your vet and keep a record of episodes to identify useful patterns.

For pet parents in Hyderabad, report any connection with construction dust, household sprays or seasonal smoke exposure rather than assuming these are the cause.

How Do You Know Whether Treatment Is Working?

Track the frequency and severity of coughing, comfort at rest and willingness to play.

Ask your vet to show you how to count resting breaths when your cat is asleep and not purring, and agree on a threshold for contacting the clinic. A change from the usual pattern can be useful, but visible breathing effort needs attention regardless of the number.

If symptoms persist, the next step may involve checking inhaler technique, reviewing the diagnosis or investigating another condition – not simply increasing medication.

A Recurring Cough Deserves an Explanation

Your cat does not need to cough every day or look unwell between episodes for an assessment to be worthwhile.

If you have noticed repeated hacking, wheezing or breathing changes, contact Mr. Vet Hospitals in Hyderabad to arrange an examination. Bring a video and a brief episode record if you can.

If your cat is struggling to breathe, seek immediate emergency care rather than waiting for a routine appointment.
