Why Is My Cat Coughing? 12 Causes, Warning Signs & When to See a Vet

Why Is My Cat Coughing?

If your cat has started coughing, it can be difficult to know whether you are hearing a true cough, a hairball attempt, gagging, or a sign of a more serious respiratory problem. Cats do cough, although coughing is less common in cats than in dogs. A persistent or recurring cough should not automatically be blamed on hairballs.

A cat cough can develop for many different reasons, including airway inflammation, feline asthma, respiratory infections, parasites, inhaled irritants, or something irritating or obstructing the airway. In some cases, coughing can also occur with more serious lung disease.

Quick Answer: Why Is My Cat Coughing?

Your cat may be coughing because something is irritating or inflaming the airways. Common causes include feline asthma or bronchitis, respiratory infections, inhaled irritants, parasites, foreign material in the airway, and other lung conditions.

One of the most important things to determine is whether your cat is actually coughing. Cats frequently crouch low, extend their neck, and make a forceful hacking or wheezing motion when coughing. This can easily be mistaken for vomiting or trying to bring up a hairball.

If the cough happens repeatedly, becomes more severe, produces mucus or blood, or occurs together with breathing difficulty, weakness, poor appetite, or weight loss, your cat should be examined by a veterinarian.

Key Takeaways

• A true cough is different from vomiting or trying to pass a hairball.
• Feline asthma and bronchitis are important causes of recurring cough in cats.

How to Tell If Your Cat Is Actually Coughing

Before trying to determine why your cat is coughing, it helps to identify what you are actually seeing. A coughing episode can look surprisingly similar to vomiting or attempting to produce a hairball.

During a typical cough, a cat may lower its body, extend its neck forward, and make repeated forceful movements as air is expelled from the lungs. The cough may sound dry, harsh, or hacking. A cat may gag at the end of a coughing episode, which is one reason owners sometimes assume the cat is trying to vomit.

With vomiting, you are more likely to see abdominal contractions followed by the expulsion of stomach contents. With a hairball attempt, the cat may repeatedly retch, but a hairball is not necessarily produced.

If you are unsure, record the episode on your phone. A short video can help your veterinarian distinguish coughing from vomiting, gagging, sneezing, or other respiratory movements.

Some cats with respiratory disease can also develop rapid or labored breathing. If your cat is coughing and you are also concerned about how easily it is breathing, treat that as a more important warning sign rather than simply watching for a hairball.

You can learn more about abnormal breathing in our guide to why cats may breathe fast.

When a Cat Cough Is an Emergency

Not every cough requires an emergency visit, but respiratory distress in a cat should never be ignored. Cats can hide signs of illness surprisingly well, and breathing problems can deteriorate quickly.

Seek urgent veterinary care if your cat is coughing and also shows any of the following:

• Open-mouth breathing or panting
• Obvious difficulty breathing
• Very rapid or labored breathing
• Blue, gray, purple, or unusually pale gums or tongue
• Severe weakness or collapse
• Repeated coughing that appears to prevent normal breathing
• Blood associated with the cough
• Sudden severe respiratory distress

These signs can occur with serious respiratory conditions, including severe asthma, fluid around the lungs, certain infections, foreign material in the airway, and other potentially life-threatening problems. A cat having significant difficulty breathing should be evaluated immediately rather than treated at home.

1. Feline Asthma

Feline asthma is one of the most important causes of recurring coughing in cats. It involves inflammation and narrowing of the airways, which can make it harder for air to move normally through the lungs.

Cats with asthma may develop a dry or harsh cough, wheezing, rapid breathing, or episodes of respiratory distress. During an episode, a cat may crouch close to the ground and stretch its neck forward. Some cats may appear as though they are trying to vomit or bring up a hairball.

Asthma can be triggered or aggravated by airborne irritants and other environmental factors. Potential triggers can include cigarette smoke, perfumes, sprays, dusty cat litter, air fresheners, cleaning products, mold, mildew, pollen, and other airborne particles.

Importantly, asthma cannot be reliably diagnosed simply by watching a cat cough. Other conditions can produce similar symptoms, so veterinarians generally need to rule out other respiratory diseases before confirming the diagnosis.

Veterinary evaluation may include a physical examination, chest X-rays, blood tests, and other diagnostic testing depending on the cat's symptoms and medical history.

Severe asthma attacks can become emergencies. If your cat suddenly has difficulty breathing or begins breathing with its mouth open, seek veterinary care immediately.

2. Bronchitis and Lower Airway Inflammation

Bronchitis occurs when the airways become inflamed. In cats, bronchitis can overlap with the same group of lower-airway diseases associated with feline asthma.

A cat with bronchitis may develop a persistent or recurring cough, wheezing, or changes in its breathing pattern. Some cats continue to eat and behave relatively normally despite having an underlying airway problem, which can make the condition easy to underestimate.

Inflammation can increase mucus production and narrow the airways. Over time, chronic airway inflammation may interfere with normal airflow and make respiratory symptoms more noticeable.

The underlying cause is important because treatment depends on the diagnosis. Your veterinarian may consider infections, allergic or inflammatory disease, parasites, environmental irritants, and other lung conditions when evaluating a coughing cat.

Do not assume that a recurring cough is simply a minor irritation, particularly if it continues for several days or repeatedly returns.

3. Respiratory Infections

Respiratory infections can also cause coughing in cats. Viral or bacterial infections may affect different parts of the respiratory tract, and coughing can occur when inflammation or secretions irritate the throat, trachea, or lower airways.

A respiratory infection may be accompanied by other symptoms, such as:

• Sneezing
• Nasal discharge
• Eye discharge
• Reduced appetite
• Lethargy
• Fever
• Coughing or noisy breathing

Not every respiratory infection produces the same combination of symptoms. Some cats may have relatively mild upper-respiratory signs, while others can develop more significant lower-airway disease.

If your cat is coughing along with sneezing or nasal discharge, our guide on why cats sneeze may also help you understand the difference between common upper-respiratory symptoms and signs that deserve veterinary attention.

4. Inhaled Irritants and Allergens

Sometimes the cause of a cat's cough is in the environment. Cats can inhale particles, fumes, or other substances that irritate their airways.

Potential respiratory irritants include:

• Cigarette or vaping smoke
• Perfume and strongly scented products
• Air fresheners
• Cleaning sprays
• Dusty cat litter
• Hairspray
• Essential oil diffusers
• Dust and household particles
• Mold or mildew
• Outdoor pollen and other airborne allergens

If your cat tends to cough in a particular room or shortly after exposure to a specific product, consider whether an environmental trigger could be contributing to the problem.

However, removing a suspected irritant should not replace veterinary evaluation when coughing is persistent, severe, recurrent, or accompanied by breathing difficulty.

5. Foreign Material or a Foreign Body

A foreign object or material can irritate the respiratory tract and trigger sudden or repeated coughing. Cats can inhale small particles, plant material, dust, or other debris, and in some cases an object can become lodged in the airway.

A cough caused by inhaled material may begin suddenly, particularly if your cat was recently playing with plants, exploring dusty areas, or exposed to small particles.

Possible signs include:

• Sudden coughing or repeated hacking
• Gagging or retching
• Wheezing or noisy breathing
• Repeated swallowing
• Difficulty breathing
• Sudden distress or restlessness

If you suspect that something is obstructing your cat's airway, do not attempt to force food, water, or medication down its throat. Respiratory distress is an emergency and requires immediate veterinary attention.

6. Parasites That Affect the Respiratory System

Some parasites can affect a cat's respiratory system and cause coughing. Depending on the parasite and the stage of infection, a cat may develop coughing, wheezing, rapid breathing, or other respiratory signs.

Heartworm disease is one important consideration. Cats can be affected by heartworms even though they are not the same type of host as dogs. Respiratory signs associated with feline heartworm disease can sometimes resemble asthma or other airway disorders.

Other respiratory parasites may also cause inflammation within the lungs or airways.

The likelihood of parasitic disease depends on factors such as geographic location, outdoor exposure, mosquito exposure, hunting behavior, and preventive care. A veterinarian may recommend specific diagnostic testing when parasites are considered possible.

Because several different respiratory conditions can look similar, coughing alone cannot determine whether parasites are responsible.

7. Pneumonia

Pneumonia is inflammation and infection of the lungs and can cause coughing in cats. It may develop from an infectious organism or, in some situations, after inhaling material into the lungs.

Cats with pneumonia may appear more obviously ill than cats with mild airway irritation. Possible signs include coughing, difficulty breathing, lethargy, fever, reduced appetite, and weakness.

A cat with pneumonia may also breathe faster or work harder to breathe. These changes are particularly concerning because they can indicate that the lungs are not functioning normally.

Pneumonia cannot be reliably diagnosed from symptoms alone. A veterinarian may need chest imaging and other diagnostic tests to determine whether the lungs are affected and identify the underlying cause.

8. Chronic Respiratory or Lung Disease

Some cats develop chronic diseases affecting the airways or lungs that lead to recurring coughing. These conditions may develop gradually, with symptoms becoming noticeable over weeks or months.

A cat with chronic respiratory disease may cough intermittently while otherwise appearing relatively normal between episodes. This can make it tempting to ignore the cough, especially when the cat continues eating and behaving normally.

However, recurring coughing is worth discussing with a veterinarian. Persistent airway inflammation can have several possible causes, and identifying the underlying problem is more useful than simply suppressing the cough.

Your veterinarian may consider your cat's age, medical history, exposure to irritants, vaccination history, indoor or outdoor lifestyle, and the characteristics of the cough when deciding which diagnostic tests are appropriate.

9. Heart Disease and Respiratory Problems

Heart disease is less commonly associated with coughing in cats than it is in dogs, but cardiovascular disease can still cause serious respiratory problems in cats.

Importantly, a cat with heart disease may show breathing abnormalities rather than a classic persistent cough. Rapid breathing, increased respiratory effort, weakness, exercise intolerance, or sudden respiratory distress can be more important clues.

Because respiratory and cardiovascular problems can overlap, a veterinarian may need to evaluate both the lungs and heart when a cat has unexplained breathing abnormalities.

If your cat's cough is accompanied by significant changes in breathing, do not wait for the cough to resolve on its own.

10. Lung Tumors or Other Masses

Lung tumors and other masses are less common causes of coughing, but they become more important considerations when a cough is persistent, progressive, or accompanied by other unexplained changes.

Depending on the underlying condition, a cat may also develop weight loss, reduced appetite, lethargy, breathing difficulty, or exercise intolerance.

These symptoms are not specific to cancer. Many other illnesses can produce the same signs. That is why a veterinarian may recommend diagnostic imaging when a cough does not have an obvious explanation or does not improve as expected.

Chest X-rays can provide valuable information about the lungs and surrounding structures, while additional tests may be recommended depending on what is found.

11. Throat or Upper Airway Irritation

Not every cough originates deep within the lungs. Irritation involving the throat, larynx, trachea, or other upper respiratory structures can also trigger coughing or repeated throat-clearing movements.

Possible triggers include inhaled dust, smoke, chemical fumes, foreign material, inflammation, or infection.

You may notice coughing after exposure to a particular environment or activity. Some cats may also swallow repeatedly, gag, sneeze, or make unusual respiratory sounds.

If the behavior continues after the suspected irritant is removed, or if your cat develops other symptoms, veterinary evaluation is appropriate.

12. Coughing With an Unclear Cause

Sometimes the initial cause of a cat's cough is not immediately obvious. This is particularly true when the cough is intermittent and the cat appears completely normal between episodes.

A veterinarian may need to combine several pieces of information rather than relying on one symptom. The frequency and duration of the cough, whether it is dry or productive, the cat's age, environmental exposures, previous illnesses, and other clinical signs can all help narrow the possibilities.

This is another reason why recording your cat during an episode can be useful. A veterinarian may be able to identify characteristics of the movement or sound that are difficult to describe accurately in words.

Dry Cough vs. Wet Cough in Cats

Pay attention to what the cough sounds and looks like. A dry cough may sound harsh or hacking without producing visible mucus. A productive cough may be accompanied by mucus or other material.

However, owners should not try to diagnose the underlying disease based solely on whether a cough sounds dry or wet. Different respiratory disorders can produce overlapping symptoms.

What You Notice	What It May Suggest	What to Do
Occasional mild cough	Temporary airway irritation is possible	Monitor closely and look for recurrence
Recurring dry cough	Airway disease such as asthma or bronchitis is possible	Arrange a veterinary evaluation
Cough with mucus	Respiratory inflammation or infection may be involved	Contact your veterinarian
Cough with breathing difficulty	Potentially serious respiratory disease	Seek urgent veterinary care
Cough with blood	Potential injury, inflammation, infection, or other serious disease	Contact a veterinarian promptly

How Long Is Too Long for a Cat to Cough?

There is no single number of days that determines whether a cough is dangerous. The severity, frequency, progression, and accompanying symptoms are more important than duration alone.

A single brief cough after inhaling dust may not mean the same thing as repeated coughing episodes occurring every day. Likewise, a cat that coughs once but otherwise acts normally is different from a cat that coughs and is simultaneously losing weight, eating less, or breathing abnormally.

Arrange a veterinary examination when coughing is persistent, recurrent, worsening, or associated with other signs of illness.

If your cat is coughing and also refusing food, you can also review our guide to why cats stop eating, because reduced appetite together with respiratory symptoms can provide important information about how unwell your cat may be.

How Veterinarians Diagnose Coughing in Cats

Because many different conditions can cause coughing, a veterinarian will usually look at the entire clinical picture rather than treating the cough as a disease by itself.

During the examination, your veterinarian may ask when the coughing started, how often it happens, whether it is getting worse, whether anything triggers it, and whether your cat has experienced changes in appetite, energy, weight, or breathing.

Your veterinarian may also ask about your cat's environment. Exposure to cigarette smoke, dusty litter, perfumes, cleaning products, air fresheners, mold, outdoor allergens, and other airborne irritants can be relevant when evaluating respiratory disease.

Common Diagnostic Tests

• Physical examination: The veterinarian listens to the heart and lungs and checks for other abnormalities.
• Chest X-rays: Radiographs can help identify changes involving the lungs, airways, heart, or chest cavity.
• Blood tests: These may help identify inflammation, infection, or other systemic problems.
• Parasite testing: Testing may be recommended when parasites are considered a possibility.
• Airway sampling: In selected cases, samples from the respiratory tract may be examined for infection or inflammation.
• Additional imaging or testing: More advanced diagnostics may be recommended when initial tests do not explain the symptoms.

The appropriate tests depend on your cat's age, symptoms, examination findings, and medical history. Not every coughing cat needs every available test.

How Is Cat Coughing Treated?

There is no single treatment for coughing in cats because coughing is a symptom rather than a specific disease. Treatment should target the underlying cause identified by the veterinarian.

For example, a cat with inflammatory airway disease may require a different treatment approach from a cat with a respiratory infection, parasite infection, pneumonia, or an inhaled foreign body.

Depending on the diagnosis, veterinary treatment may involve medications to reduce airway inflammation, treatment for an infection or parasite, oxygen support for cats experiencing respiratory distress, or other interventions appropriate for the underlying condition.

Never give your cat human cough medicine unless your veterinarian specifically tells you to do so. Some ingredients that are safe for people can be dangerous to cats, and suppressing a cough without addressing its cause may delay appropriate treatment.

What Can You Do at Home if Your Cat Is Coughing?

If your cat is otherwise comfortable and does not have emergency breathing signs, there are several practical things you can do while arranging or waiting for veterinary advice.

1. Reduce Airborne Irritants

Keep your cat away from cigarette smoke, vaping aerosols, strong perfumes, aerosol sprays, and heavily scented cleaning products. If dusty litter appears to trigger coughing, consider discussing a lower-dust alternative with your veterinarian.

2. Keep the Environment Calm

Stress and excessive activity can make respiratory symptoms more difficult for an already unwell cat. Give your cat a quiet, comfortable place to rest and avoid unnecessary handling if breathing appears difficult.

3. Monitor Eating and Drinking

Changes in appetite and water intake can provide useful information about your cat's overall condition. A cat that stops eating, becomes unusually weak, or develops other symptoms alongside coughing should be evaluated by a veterinarian.

4. Record the Cough

Try to record a short video when the coughing occurs. Include the entire episode if possible, rather than only the sound. The position of your cat's body, breathing pattern, and movements can help a veterinarian distinguish coughing from gagging, vomiting, sneezing, or other behaviors.

5. Do Not Force Medication or Food

If your cat is having difficulty breathing or repeatedly gagging, forcing food, water, or medication can increase stress and may be unsafe. In that situation, seek veterinary advice rather than attempting home treatment.

Can Cat Coughing Be Prevented?

Not every cause of coughing can be prevented, but reducing respiratory irritants and maintaining routine veterinary care can help lower some risks and identify problems earlier.

• Keep your home free from cigarette and vaping smoke.
• Minimize exposure to strong fragrances and aerosolized chemicals.
• Keep litter areas clean and consider low-dust litter when appropriate.
• Control household dust and improve ventilation.
• Keep your cat's vaccinations and preventive veterinary care up to date.
• Discuss parasite prevention with your veterinarian.
• Monitor recurring respiratory symptoms rather than repeatedly assuming they are hairballs.

Good overall care also includes paying attention to hydration, nutrition, grooming, activity, and changes in normal behavior. Our complete guide to keeping your cat healthy covers these everyday fundamentals in more detail.

Cat Coughing vs. Other Common Symptoms

One reason respiratory problems can be confusing for cat owners is that coughing can look similar to several other behaviors. Recognizing the differences can help you describe the problem more accurately to your veterinarian.

Symptom	Typical Appearance	What to Watch For
Coughing	Crouched posture, extended neck, forceful hacking	Frequency, wheezing, breathing changes
Vomiting	Abdominal contractions followed by expulsion of stomach contents	Repeated vomiting, blood, appetite changes
Hairball attempt	Repeated retching or gagging	Frequency and whether other symptoms develop
Sneezing	Forceful expulsion of air primarily through the nose	Nasal discharge, congestion, eye discharge
Breathing difficulty	Increased effort, rapid breathing, or open-mouth breathing	Urgent veterinary attention

When Should You Call the Vet About a Cough?

Contact your veterinarian if your cat has a cough that is persistent, recurrent, worsening, or accompanied by other signs of illness.

You should be especially concerned if coughing occurs together with:

• Loss of appetite
• Weight loss
• Unusual tiredness or weakness
• Fever
• Wheezing
• Nasal or eye discharge
• Rapid breathing
• Increased breathing effort
• Coughing up blood or abnormal material

For a broader look at symptoms that may accompany illness, see our guide to common causes of vomiting in cats if your cat is also retching or bringing up material.

Frequently Asked Questions About Cat Coughing

Why is my cat coughing but otherwise acting normal?

A cat can appear normal between coughing episodes even when an underlying respiratory problem is present. Mild irritation, asthma, chronic airway inflammation, or other conditions can cause intermittent coughing. If the cough keeps returning, arrange a veterinary evaluation rather than assuming it is a hairball.

Can hairballs cause coughing in cats?

Hairball attempts are often mistaken for coughing. A cat trying to produce a hairball may retch or gag, while a true cough generally involves forceful expulsion of air from the lower respiratory tract. If you cannot tell the difference, recording an episode for your veterinarian can be helpful.

Why does my cat cough and wheeze?

Coughing and wheezing can occur with inflammatory airway conditions such as feline asthma or bronchitis, but other respiratory diseases can produce similar signs. A veterinarian should determine the underlying cause, particularly when symptoms recur.

Why is my cat coughing at night?

The timing of coughing alone does not identify the cause. Nighttime coughing can occur with several respiratory conditions or environmental exposures. Note when the episodes happen, where your cat is sleeping, and whether anything in the environment changes before the cough starts.

Can cats get asthma?

Yes. Feline asthma is an important cause of lower-airway inflammation and can produce coughing, wheezing, and breathing difficulty. Because other diseases can look similar, veterinary examination is needed for an accurate diagnosis.

Is cat coughing always serious?

No. A brief cough caused by temporary airway irritation may resolve without becoming a serious problem. However, frequent, persistent, worsening, or severe coughing deserves veterinary attention, especially when other symptoms are present.

What should I do if my cat is coughing and breathing fast?

Take breathing changes seriously. If your cat is breathing with obvious effort, using its mouth to breathe, has blue or gray gums, collapses, or appears severely distressed, seek emergency veterinary care immediately.

Can I give my cat cough medicine?

Do not give human cough medicine unless your veterinarian specifically prescribes or recommends a medication and dose for your cat. Human medications can contain ingredients that are unsafe for cats.

Final Takeaway: Don't Automatically Blame a Cough on Hairballs

A coughing cat may have a relatively minor airway irritation, but recurring coughing can also be a sign of asthma, bronchitis, infection, parasites, pneumonia, or another respiratory condition.

The most useful first step is to determine whether your cat is truly coughing rather than vomiting, gagging, or trying to pass a hairball. Record an episode if possible, remove obvious airborne irritants, and monitor your cat for changes in appetite, energy, and breathing.

If coughing continues, keeps returning, or is accompanied by abnormal breathing or other signs of illness, contact your veterinarian.
