Coughing is very common with cats and can be triggered by numerous causes. A cough is an explosive expulsion of air from the lungs through the cat’s mouth. The trigger for this symptom is always a stimulus that triggers the associated cough reflex. The objective of this reflex is either to cough out foreign bodies or to remove bronchial mucus from the respiratory tract.
Due to the diverse nature of how coughs develop in cats, it makes sense to split the causes into infectious and non-infectious categories for better understanding:
Aspirated foreign bodies (e.g. blades of grass or strands) found in the respiratory tract are particularly common causes of acute coughing in cats. For instance, blades of grass stick to the palate and lead to a retching cough. Besides though, allergic reactions such as feline asthma, respiratory tract injuries and inhaling gases (e.g. as part of smoke intoxication) can also lead to coughing in cats. Feline asthma causes severe inflammation of the bronchi, which is typically characterised by attacks of shortness of breath and retching at the end of the cough. A tumour is also another possibility for chronic cat coughs. Unlike dogs, cats don’t cough due to cardiac diseases.
This category includes numerous bacterial and viral antigens, as well as fungi and parasites:
Kittens in particular often show signs of infection from cat colds. This infectious disease occurs globally and leads to conjunctivitis and damage to the mucous membrane along with coughing.
The following pathogens play a significant role in the onset of the disease:
Along with cat colds, however, parasites can also lead to coughing. For example, pulmonary worms can enter the respiratory tract through oral ingestion. The worms there cause inflammatory reactions.
The character of the cough and possible concomitant symptoms depend on the reason for the illness:

It is very important for the vet to define the character of the cough in order to make a diagnosis. The vet asks about the frequency and intensity of the cough, its productivity (coughing up possible fluids) or whether coughing increases in certain situations (e.g. when eating). It is also beneficial to be able to assess whether it is an acute or chronic cough in order to better narrow down differential diagnoses. Whilst tumourous events are usually chronic, a blade of grass that gets stuck causes acute coughing instead.
If the vet is able to categorise the cough more precisely on the basis of the information requested, this leads to a general clinical examination as the next step. This allows the cat’s current state of health to be determined using several vital parameters. These include:
The cat having a stable circulatory condition is important for further examining the respiratory tract. If the vital parameters show something different, it may be necessary to carry out infusions to stabilise circulation.
Different diagnostic methods can be used during further examination. Adspection (observation) and cautious palpation (touching) of the oral cavity can rule out existing foreign bodies. The vet then uses a stethoscope to monitor the respiratory tract. If there is any suspicion that internal structures may be altered (e.g. due to tumours), the organs in the rib cage, especially the lungs, will be more closely examined using imaging procedures (e.g. X-rays). However, blood and faecal analysis have proved to be particularly useful in clearing up infectious diseases.
Treating cat coughs depends greatly on the particular cause. Treatment can be special or symptomatic.
Special treatment:
Symptomatic treatment:
Like treatment, prognosis of cat coughs depends on the underlying disease. As a rule, a pulmonary worm infestation diagnosed at an early stage in cats can be well treated with worming medication. This is also the case with cat colds and other infectious diseases. The prognosis of feline asthma depends on the allergens that trigger it. If it’s possible for the cat to entirely avoid contact with allergens, the prognosis for an undisrupted feline life is good. If the allergens cannot be avoided, it is possible to alleviate symptoms with certain medication to improve quality of life.
The following preventive measures are helpful to avoid infectious diseases:
Are you concerned about your ageing cat's lack of response to its name? Or are you startled by your cat's inability to locate its food bowl? Allow us to explain how you can identify early signs of senility in your cat and enable it to lead a lengthy and robust life.
How long do cats take to grow and how big do they get? This depends partly on their genetic make-up and external factors such as diet. Cats have six growth phases. If we are aware of these, we can give our cats the perfect start to a healthy life and support them as well as possible on the road to adulthood.
Is there a better sound than a cat purring? For cat lovers, there surely isn't. Cats purr when they feel happy and this good feeling is spread to their owner. But did you know that cats also purr when injured or stressed? Read on to find out why cats purr and how they make this continuous, deep humming sound.
