Cat coughing can be easy to dismiss as a hairball, but it is not always one. Cats are good at hiding illness, so a cough deserves attention, especially if it keeps happening. This guide is general information and not a diagnosis.
Is it a cough or a hairball?
A hairball usually involves hacking and retching, followed by a wad of hair. It may happen once in a while. A true cough is a sharper, repeated sound, often with your cat crouched low, neck stretched forward, and nothing coming up. If you are unsure, record a short video to show your vet.
Common causes of cat coughing
- Hairballs: occasional and usually not serious
- Feline asthma or allergic airway disease: causes recurring coughing and wheezing
- Respiratory infections: often with sneezing, eye or nose discharge
- Heart disease: can cause fast or difficult breathing or tiring easily; coughing is not a typical sign of heart disease in cats
- Heartworm-associated disease: can affect cats, even indoor ones
- Lungworms and other parasites
- Foreign material or irritants: such as smoke, dust, scented litter or sprays
- Growths or other airway conditions
Signs that need a vet quickly
Get urgent help if your cat is:
- Breathing with an open mouth
- Breathing fast or with obvious effort at rest
- Wheezing, or with blue, gray or pale gums
- Coughing repeatedly or collapsing
- Refusing food or very lethargic
Open-mouth breathing in a cat is an emergency. Go to the nearest emergency clinic.
What you can do at home
- Note how often it happens and when
- Reduce irritants: switch to unscented, low-dust litter and avoid aerosols and smoke
- Keep up with grooming to reduce hairballs
- Count your cat's resting breaths per minute while asleep, and share that number with your vet
Do not give human cough medicine to cats. Many ingredients are toxic.
What a vet may recommend
A vet may listen to the lungs and heart, recommend chest X-rays, bloodwork or other tests, and discuss treatment. Cats with asthma may be prescribed inhalers or medication.
If your cat is coughing and you are not sure how urgent it is, you can chat with a licensed vet on Waggle Vet and share a video of the cough. For an in-person exam, find a vet near me.
