Hearing your cat cough is unsettling. It might sound like a dry hack, a wet wheeze, or even a honking noise that makes you wonder if something is stuck. The good news is that many causes of coughing in cats are manageable, and a few simple changes around the house can make a big difference. But first, you need to know what you’re dealing with. Let’s walk through the most common reasons your cat might be coughing and what you can do about it.
1. Hairballs: The Most Common Culprit
If your cat coughs and then produces a foamy, tube-shaped mass, that’s a hairball. Cats groom themselves constantly, and loose fur can collect in the stomach. Usually, they vomit it up, but sometimes it triggers a coughing reflex as the fur irritates the throat. You can help by brushing your cat daily to remove loose fur before it gets swallowed. If hairballs become frequent (more than once a month), talk to your vet. Adding a cat probiotic supplement can support digestion and help move hair through the system more smoothly.
2. Feline Asthma: A Common Respiratory Issue
Asthma in cats looks a lot like a human asthma attack: a dry, persistent cough, often with the neck extended and the body low to the ground. Triggers can include dust, pollen, smoke, or even scented candles. If you notice your cat coughing after you vacuum or light a candle, try removing those triggers first. Keep your home well-ventilated and use an air purifier. For stressed cats, a cat calming collar can reduce anxiety that might worsen asthma symptoms. But if the coughing is frequent or severe, your vet may prescribe an inhaler or medication.

3. Respiratory Infections (Upper and Lower)
Just like humans, cats can catch colds. Viral infections like feline herpesvirus or calicivirus can cause coughing, sneezing, and runny eyes. Bacterial infections are less common but can follow a virus. If your cat has a fever, is lethargic, or has discharge from the nose or eyes, a vet visit is essential. Keep your cat hydrated and comfortable. If your cat is eating less due to a stuffy nose, switching to elevated cat bowls can make swallowing easier and encourage them to eat.
4. Foreign Objects and Irritants
Cats are curious and sometimes inhale a blade of grass, a piece of string, or a small toy part. This can cause a sudden, violent cough as the body tries to expel the object. If your cat is pawing at their mouth, drooling, or gagging, check their mouth carefully. Never pull a string that’s already partially swallowed, as it can damage the intestines. If the coughing doesn’t stop or you see signs of choking, go to the vet immediately. Also, avoid using aerosol sprays, strong cleaners, or incense around your cat, as these can irritate their sensitive airways.
Cats have a very sensitive cough reflex. Unlike dogs, cats rarely cough just from kennel cough or minor irritation. If your cat is coughing repeatedly, it’s almost always a sign that something specific is going on, not just a passing tickle.
5. Heartworm or Lungworm
Yes, cats can get heartworm, even if they live indoors. Mosquitoes carry the larvae, and once inside a cat, the worms can lodge in the lungs or heart, causing a chronic cough. Lungworm is another parasite that lives in the airways and triggers coughing. These are serious conditions, but they are preventable with monthly vet-prescribed treatments. If your cat is on a prevention plan, you’re already covered. If not, talk to your vet about testing and prevention.
6. When to See the Vet and What to Expect
A single cough after a hairball is usually nothing to worry about. But you should call your vet if: the coughing lasts more than a few days, your cat is breathing with an open mouth, their gums look blue or pale, they are lethargic, or they stop eating. The vet may take X-rays, blood tests, or even a sample of fluid from the airways. Be prepared to describe the cough: is it dry or wet? Does it happen at rest or after activity? Does your cat cough more at night? This info helps the vet narrow it down quickly. Remember, you know your cat best, so trust your gut.
Coughing in cats is rarely a simple thing to ignore, but with a little detective work and a good relationship with your vet, you can usually get to the bottom of it. Small changes like reducing dust, brushing more often, and using elevated cat bowls can make a real difference in your cat’s daily comfort. And if your cat seems stressed by the coughing episodes, a cat calming collar might help them relax while you work with your vet on a long-term plan.
