Cat Coughing Feature

Coughing in cats usually indicates a health problem. If you hear your cat coughing, it’s time to schedule a visit to the veterinarian. Many different medical conditions can cause coughing in cats, some of which can be serious or contagious to other cats. 

About Cat Coughing

Since coughing is somewhat uncommon in cats, you might be wondering, what does cat coughing sound like? That can depend on the type of cough your cat has. Cat coughing can be wet (moist and phlegmy sounding) or dry (which may sound like hacking). Coughing cats might sound like they are gagging or vomiting, and coughing cat might even cough up a foamy substance that looks like vomit. 

When a cat “coughs up” a hairball, she is actually vomiting. However, if a hairball becomes stuck on its way up and out of the esophagus, a cat might cough and hack and yack repeatedly in an attempt to expel it. If your cat produces a wad of hair, it’s likely the coughing is related to a hairball, especially if your cat doesn’t have any other symptoms. 

A cat vomiting can sometimes sound like coughing, especially if there is a lot of gaging and hacking going on. If you find a puddle of bile or food (and not just clear foam), it’s likely your cat is vomiting rather than coughing. Both vomiting and coughing warrant a visit to the veterinarian, especially if the cat is acting very sick (not eating, laying around, experiencing diarrhea, etc.). 

Why Is My Cat Coughing?

Like humans, cats may start coughing for a wide range of reasons.

Causes of coughing in cats vary. Some of the most common causes of coughing in cats include: 


Coughing in cats is frequently due to allergies. Cats can be allergic to many different substances, including air fresheners, irritants or chemicals in the home, cigarette smoke, dust from cat litter, mold, perfume and pollen, among many other things. 

Infection of the upper or lower respiratory tract

Viral or bacterial respiratory infections are quite common in cats, especially those housed in places with high numbers of cats like shelters. Cats that are coughing due to an upper respiratory infection may also experience congestion, sneezing, runny nose and decreased appetite. 


Feline asthma is a common cause of coughing in cats. Asthma can be triggered by many of the same things as allergies (see above). Cats that have asthma usually wheeze in addition to coughing and possibly gagging. Asthma is a serious condition because it inhibits the cat’s breathing. In fact, an asthma attack can be a medical emergency. If you see your cat coughing, wheezing or breathing with her mouth open, or notice that your cat’s gums or tongue look blue or gray, bring your cat to a veterinarian immediately. Cats suffering from an asthma attack may also hunch low to the floor, stretching out their head and neck out as they attempt to breathe. 


Feline bordetellosis, caused by the bacteria Bordetella bronchiseptica, is an extremely contagious disease that causes upper-respiratory infections. Bordetella infection is more common in cats housed in animal shelters, pet stores or breeding facilities. Very young kittens are especially susceptible.

Damage to the windpipe

If your cat’s collar is too tight or she suffers an injury to her trachea, it can cause coughing. 


Laryngitis, or inflammation of the larynx, may cause coughing in cats. Cats that cough after eating or while they are eating might have a disease of the larynx or esophagus.

Foreign body in the airway

Cats sometimes inhale tiny bits of grass or seeds, which irritate the airway, causing coughing.

Heart disease

Coughing due to congestive heart failure is more common in dogs than cats, but cats may also cough when their heart function is diminished. 


Lungworms are parasites that take up residence in the lungs, where they wreak havoc. Lung worms are a type of roundworm (nematode). In addition to coughing, symptoms of lungworm in cats also include difficulty breathing. 


Although heartworms are less common in cats than dogs, cats can become infected with this parasite. Heartworms take up residence in the heart, where they grow and constrict the heart. Heartworm disease in cats is fatal, so using a monthly heartworm preventive is recommended, especially for outdoor cats or those living in heartworm endemic 

Lung cancer

Coughing is one of the signs of lung cancer in cats, although many cats with lung cancer often display no symptoms.

Pneumonia (lung infection)

Pneumonia is an infection of the lungs may be caused by a virus, bacteria or fungus. Cats may suffer from pneumonia if they accidentally aspirate (inhale) liquid or food into the lungs. 

What to Do If Your Cat Starts Coughing

What to do if your cat starts coughing

A cat coughing doesn’t always necessitate a trip to the vet, but in some cases, a vet visit may be essential. Your vet can help you to identify and resolve the underlying cause of your cat’s cough.

If you think your cat is coughing, pay attention to when she’s coughing, how often she’s coughing and what the cough sounds like. Your veterinarian might ask you to describe the sound of the cough if your cat isn’t actively coughing when you bring her in for an exam. If you can, try to take a video of your cat coughing to show the veterinarian. 

If your cat just coughs once or twice, and otherwise seems fine, you could watch her and see if the cough goes away on its own. Continuous coughing should be checked out by your vet, even if your cat is not coughing all day long. Take your cat in right away if she seems to be having difficulty breathing (panting or wheezing) or is acting very sick (not eating, lethargic, experiencing discharge from the nose or eyes, vomiting, or having diarrhea). 

The veterinarian will ask you a lot questions about your cat’s cough, and will conduct a complete physical exam. The vet might also want to run tests like blood work, urinalysis, x-rays or ultrasound, or other tests. Treatment for cat coughing depends on the underlying cause of the cough, but may entail supportive care, medications, lifestyle changes or surgery. 

Do Not Ignore Cat Coughing

Cats don’t typically cough, so if you hear your cat coughing, do not let it go. In some cases of cat coughing, quick treatment is necessary. Many causes of coughing in cats can be resolved with veterinary intervention.
