Why Is My Cat Coughing? Expert Insights, Symptoms & Care

Noticing your cat cough can be unsettling, but is it something serious or just a harmless reflex? While an occasional dry cough may be nothing, persistent coughing could signal something deeper, from feline asthma to respiratory infections or even heart disease. Many cat parents confuse coughing with gagging or vomiting, but they’re not the same.

• Coughing is a forceful burst of air from the lungs.
• Gagging often involves throat irritation or hairballs.
• Vomiting expels stomach contents with abdominal effort.

Recognizing this difference matters. In this post, you’ll uncover the real causes behind cat coughing, signs to watch for, and vet-approved advice on when to take action.

What’s Making Your Cat Cough? 7 Common Causes Explained

Cat coughing can be puzzling—sometimes it’s harmless, other times it’s a sign of something serious. While many assume coughing means hairballs, the reality is more complex. From minor irritants to underlying health issues, it’s important to understand what could be going on. Let’s break down the most common causes of coughing in cats, what signs to watch for, and when it’s time to see the vet.

Hairballs – The Usual Suspect

Hairballs are a frequent reason for cat coughing, especially in long-haired breeds. The cough sounds dry and hacking and may end in retching or vomiting. However, if your cat is coughing but no hairball appears, it could signal another issue. Many owners confuse coughing with gagging—knowing the difference matters.

Feline Asthma

Feline asthma often goes unnoticed until symptoms like wheezing, labored breathing, or a hunched posture during coughing appear. Triggers include dust, aerosols, or smoke. A coughing fit after spraying air freshener? That might be asthma, not a furball.

According to the Cornell Feline Health Center “Feline asthma affects between 1% to 5% of cats.”

Feline asthma affects around 1% of cats, yet many are never diagnosed. A vet visit and chest X-ray are key to confirming this condition.

Respiratory Infections – Viral or Bacterial

Upper respiratory infections (URIs), bronchitis, or pneumonia can all cause coughing in cats. Look for signs like sneezing, nasal discharge, eye goop, or fatigue. These infections are contagious, especially in shelters or multi-cat homes.

According to the Cornell Feline Health Center, respiratory infections are common in cats, especially in high-density populations like shelters. A variety of viruses and bacteria can cause these infections, impacting feline health.

Allergies – Often Misunderstood

Many cats develop coughs due to environmental allergens like pollen, cleaning agents, or mold. Food sensitivities can also lead to postnasal drip and irritation. Unlike dogs, cats often show respiratory symptoms rather than skin issues when allergic. If your cat’s coughing is seasonal or happens around cleaning time, allergies could be the cause.

Heart Disease

A persistent soft cough may point to heart issues such as hypertrophic cardiomyopathy. This condition causes fluid to build up in the lungs, leading to coughing and shortness of breath. Because symptoms mimic asthma or aging, it’s often missed.

Lungworms & Parasites – Rare but Real

Though uncommon, parasites like lungworms can trigger chronic coughing, weight loss, and dull fur. Cats become infected by ingesting birds, snails, or contaminated water. Outdoor or hunting cats face a higher risk.

Foreign Objects or Irritation

Sudden coughing while eating or playing might mean your cat has inhaled something—grass, a toy piece, even string. Signs include gagging, pawing at the mouth, or sudden distress. Never attempt to remove an object yourself.

Types of Cat Coughs

Understanding your cat’s cough is key to uncovering the underlying issue. While a single cough may seem harmless, recurring or patterned coughing often points to a deeper problem. Identifying the type of cough—whether dry, wet, sudden, chronic, or nighttime—can guide timely decisions and better care.

Dry Cough

A dry, hacky cough with no mucus is often linked to asthma, allergies, or environmental irritants. Frequent episodes or labored breathing require a vet visit.

Wet Cough

A moist, gurgly cough signals mucus or fluid in the airways, commonly from infections like pneumonia or bronchitis. If your cat has nasal discharge or fever, see a vet right away.

Nighttime Coughing

Coughing at night could indicate heart disease, especially if paired with fatigue or rapid breathing. Allergens in bedding or fluid in the lungs might also be triggers.

Sudden vs. Chronic Cough

A sudden cough could be caused by a foreign object or irritant, but if it lasts more than 24 hours, consult a vet. Chronic coughing (over two weeks) may point to asthma, parasites, or allergies.

Cough Timing

When your cat coughs offers vital clues. Coughing after meals may be acid reflux, while coughing during activity could signal stress or asthma. Track symptoms to aid diagnosis.
Now that you understand the types of coughs, let’s explore what additional symptoms might mean when they appear alongside coughing.

Cat Coughing With Other Symptoms

A cat’s cough often isn’t just a standalone issue—it can come with other symptoms that reveal a deeper problem. Whether paired with sneezing, wheezing, gagging, vomiting, or even blood, these combinations can point to serious conditions. Recognizing these patterns early is crucial for quick, effective care.

Coughing and Sneezing

This combo often indicates an upper respiratory infection (URI), caused by viruses like feline herpesvirus or bacteria like Bordetella. Symptoms may include nasal discharge, watery eyes, and fever.

Coughing and Wheezing

Common signs of feline asthma or chronic bronchitis, this pairing can be triggered by allergens. If you notice wheezing, consult a vet about inhalers or environmental changes, as untreated asthma can worsen quickly.

Coughing and Gagging

Frequent coughing and gagging may be linked to hairballs, especially in long-haired cats. If persistent, it could indicate parasites or an obstruction. A vet check and hairball remedies are recommended.

Coughing and Vomiting

This serious combo could suggest gastrointestinal issues, toxin ingestion, or severe hairballs. Vomiting with foam or blood requires immediate veterinary attention.

Coughing Up Blood

A medical emergency, coughing up blood, could signal trauma, lung disease, or fungal infections. Seek emergency vet care immediately if this occurs—swift intervention is crucial for your cat’s survival.

When Is Cat Coughing an Emergency?

If your cat’s cough lingers for more than three days, worsens, or comes with labored breathing, lethargy, or loss of appetite, it’s time to act. Occasional coughing might seem harmless, but it could signal feline asthma, heart disease, infection, or even parasites. Red flags like blue gums, open-mouth breathing, coughing up blood, or sudden weight loss demand immediate veterinary care.
During a vet visit, expect a physical exam, X-rays, bloodwork, and possibly a referral to a specialist. Delaying care risks turning treatable issues into chronic ones. Pro tip: log your cat’s symptoms and bring that info to the vet. When in doubt, don’t wait—call your vet. Early help saves lives.

How to Help Your Cat at Home

When your cat starts coughing, it’s easy to feel worried—but with the right at-home care, you can provide meaningful relief while keeping an eye on symptoms. Start by adding a cool-mist humidifier to moisten dry indoor air, especially if your home has heating or AC. Switch to unscented, low-dust litter to avoid irritants that worsen respiratory issues.
Daily brushing reduces hairball-triggered coughing, particularly in long-haired cats. Boost hydration by mixing water or bone broth into meals or offering a cat-safe water fountain. Consider vet-approved supplements like omega-3s or L-lysine for immune and respiratory support.
And most importantly, watch for red flags like wheezing, lethargy, or blue gums. If these appear, skip the home remedies—call your vet immediately.

Treatment Options from Veterinarians

When your cat develops a persistent cough, veterinary treatment isn’t one-size-fits-all—it hinges on pinpointing the root cause. Once your vet finds the cause, they might prescribe medications like antibiotics (for infections), inhalers or steroids (for asthma), or drugs that help your cat breathe more easily. In cases involving parasites, dewormers like fenbendazole can resolve symptoms that mimic asthma.
But care doesn’t stop there. In more serious cases, treatments like oxygen support or using special allergy-friendly food may help your cat recover faster, especially in chronic or severe cases. Diagnostic tools like fecal exams and chest X-rays help avoid misdiagnosis—a surprising number of indoor cats test positive for lungworms.
Pro tip – Always avoid human meds without vet approval.

Preventing Future Coughing Episodes

To keep your cat cough-free, focus on long-term respiratory health, not just short-term fixes. A healthy weight matters: overweight cats are more prone to asthma and airway inflammation.
Feed a high-protein, grain-free diet, use portion control, and check weight regularly. Clean air is crucial—run a HEPA filter, avoid scented products, and reduce airborne irritants. Even mild coughing shouldn’t be ignored—schedule annual vet checkups and monitor high-risk breeds like Persians.
Wash bedding weekly and limit houseplants. Parasite prevention and calm, well-ventilated environments during renovations also go a long way.
