Cat Coughing When Breathing: Causes and What to Do
Cat coughing can indicate asthma, respiratory infections, hairballs, or more serious conditions, and distinguishing the pattern helps guide care.
Quick Answer
Cat coughing during breathing may be related to specific triggers, environmental factors, or the body response to certain activities or times of day. Cat coughing may be caused by hairballs, feline asthma, respiratory infections, allergies, or foreign bodies in the airway. Occasional coughing associated with hairballs is common, but persistent coughing, coughing with wheezing or labored breathing, or coughing with lethargy requires veterinary evaluation. If the coughing occurs consistently during breathing and is accompanied by other signs, contact a veterinarian for evaluation.

What Coughing Can Look Like
Coughing in cats is a reflexive expulsion of air from the lungs. A coughing cat typically crouches low, extends its neck, and makes a hacking or gagging sound. The cough may be dry or productive. Cat coughing is sometimes mistaken for retching or hairball attempts. When coughing occurs specifically during breathing, the timing may provide clues about the underlying cause. The pattern of coughing during breathing can help a veterinarian narrow down possible explanations.
What May Be Associated with Coughing
Similar signs can have different causes, and the following are possible explanations a veterinarian may consider.
Hairballs
Cats groom extensively and may accumulate hair in the stomach. Coughing or hacking associated with bringing up a hairball is common and usually not concerning if it happens occasionally.
Feline Asthma
Asthma is a common cause of chronic coughing in cats. Allergens such as dust, pollen, mold, and smoke trigger airway inflammation and constriction.
Respiratory Infections
Viral infections like feline herpesvirus and calicivirus, as well as bacterial infections, can cause coughing. These are often accompanied by sneezing, nasal discharge, and eye discharge.
Allergies and Irritants
Dust, pollen, mold, cigarette smoke, scented litter, and household chemicals can irritate a cat airways and trigger coughing.
Foreign Bodies
A foreign object in the throat or airway can cause sudden, persistent coughing.
What to Monitor
Tracking details helps a veterinarian assess the situation.
- Frequency and duration of coughing episodes
- Sound: Dry, wet, honking, or hacking
- Whether the cough produces hairballs, mucus, or nothing
- Breathing: Whether the cat wheezes or shows labored breathing between coughs
- Appetite and energy levels
- Triggers: Whether coughing occurs after eating, playing, or exposure to dust
- Whether coughing occurs only during breathing or at other times as well
What You Can Safely Do Next
For a cat with occasional coughing that is otherwise normal, monitor the environment for irritants. Use unscented, low-dust litter, avoid smoking indoors, and reduce scented products. Regular grooming can help reduce hairballs. Do not give human cough medicines. If coughing persists, is frequent, or is accompanied by breathing difficulty, contact a veterinarian.
When to Contact a Veterinarian
Some situations require immediate veterinary attention, while others may allow for monitoring. When in doubt, contacting a veterinarian is the safest approach.
Emergency Signs
Contact a veterinarian or emergency clinic immediately if you observe any of the following:
- Coughing with labored or heavy breathing
- Open-mouth breathing or blue gums
- Coughing that does not stop or becomes progressively worse
- Collapse or extreme lethargy
These signs may indicate a serious condition that requires prompt evaluation. In the US, the ASPCA Animal Poison Control Center can be reached at 888-426-4435 if toxin exposure is suspected. In the UK, contact your veterinarian or the Veterinary Poisons Information Service for guidance.
Non-Urgent Signs
The following may warrant a routine veterinary call rather than emergency care:
- Occasional coughing associated with hairballs in an otherwise healthy cat
- Mild coughing that resolves after removing an environmental irritant
Frequently Asked Questions
How can I tell if my cat is coughing or trying to bring up a hairball?
Both can look similar, with the cat crouching and extending its neck. Hairball attempts often end with bringing up a hairball. Coughing from respiratory causes tends to be drier and may recur without producing anything. A veterinarian can help distinguish between the two.
Can cats develop asthma?
Yes, feline asthma is a well-recognized condition that causes airway inflammation, coughing, wheezing, and breathing difficulty. It is often triggered by environmental allergens. A veterinarian can diagnose and recommend management strategies.
Why does my cat have coughing during breathing?
Coughing during breathing may be related to specific triggers, environmental factors, or the body response to certain conditions. Tracking when it occurs and what precedes it can help a veterinarian identify the pattern and possible cause.
