Cat flu is a respiratory disease in cats caused by various pathogens. It is a complex of symptoms that primarily affects the nose, mouth and eyes of the animals. The disease is contagious and can have varying degrees of severity, from mild symptoms to serious illness.

The main pathogens of cat flu are:

  • Feline herpesvirus 1 (FHV 1) , which belongs to the herpes viruses.
  • Feline Calicivirus (FCV).
  • Chlamydia , Bordetella and Mycoplasma . These pathogens can occur either alone (as a mono-infection) or in combination with each other (as a mixed infection).

Diagnosing cat flu is not always easy, as the symptoms are often similar to those of other diseases. An accurate diagnosis can usually only be made through specific laboratory tests. This is important in order to initiate appropriate treatment and restore the cat's health.

Can cat flu be transmitted to humans?

Cat flu is a contagious respiratory disease in cats caused by various viruses and bacteria. For cats, this disease is highly contagious and can be transmitted from one animal to another. The good news for cat owners is that transmission of cat flu to humans is very rare. In most cases, people do not need to worry about catching the disease from their sick cat.

However, there are exceptions: if cat flu is caused by certain bacteria such as chlamydia or Bordetella bronchiseptica, it is theoretically possible for it to be transmitted to humans. This is especially the case for people with a weak immune system. Nevertheless, it is important to stress that such cases are extremely rare and transmission is not the norm.

To minimize the risk of infection, it is important to maintain good hygiene. This includes washing hands regularly after contact with the sick cat and disinfecting surfaces where the cat has been lying. These measures help to reduce the risk of infection for both other animals and people.

Symptoms of cat flu in humans

Although transmission of cat flu to humans is rare, symptoms similar to those of a severe cold can occur. These symptoms include high fever, coughing, and difficulty breathing. These signs should be taken seriously, especially if they occur after close contact with a sick cat.

The symptoms can be particularly noticeable in immunocompromised people, young children or the elderly, as their defenses are not as strong. If such symptoms occur, it is advisable to consult a doctor to determine the cause and rule out possible infection.

It is important to note that not every cough or fever indicates infection with cat flu. Many other diseases can cause similar symptoms. Only a medical examination can provide clarity as to whether it is a transmission of cat flu or another disease.

Is cat flu dangerous for humans?

There is no general answer to the question of whether cat flu can be dangerous for humans. In the vast majority of cases, there is no reason to worry, as the pathogens that cause cat flu specifically affect cats and transmission to humans is extremely rare.

However, certain pathogens such as chlamydia or Bordetella bronchiseptica may pose a small risk of transmission to humans, especially if the immune system is weakened. In such cases, symptoms may be severe and require medical treatment.

Overall, the risk of cat flu becoming dangerous for humans is very low. However, it is always better to be cautious and consult a doctor if symptoms appear after contact with a sick cat.

How can infection be avoided?

To avoid infection with cat flu, vaccinating your cat is one of the most important measures. Basic immunization can significantly reduce the risk of infection. It is also advisable to avoid contact with other infected animals and to maintain good hygiene.

The following measures can help prevent the transmission of cat flu to humans:

  • Wash your hands regularly after contact with the cat.
  • Cleaning and disinfecting surfaces that the cat has touched.
  • Avoid close facial contact with the sick cat.

It is also helpful to improve the cat's health in general by providing high-quality food and avoiding stress. These measures help to support the cat's immune system and reduce the likelihood of illness.

duration of infection of cat flu

The duration of contagiousness of cat flu can vary depending on how badly the cat is affected by the virus and how well its immune system is functioning. On average, cats are contagious for about 10 to 20 days after the onset of the illness. During this time, you should be especially careful to minimize your cat's contact with other animals to prevent the spread of the disease.

There are some signs that indicate a cat may no longer be contagious. These include:

  • The return to normal behavior and appetite,
  • Disappearance of symptoms such as sneezing and coughing,
  • Clear eyes with no discharge. However, it is important to have a veterinarian confirm that your cat is healthy again before it has contact with other animals again. Early and correct treatment plays a crucial role in shortening the period of infection and avoiding complications.

Treatment of cat flu

If your cat is suffering from cat flu, it is important to act quickly . Treatment is carried out by a veterinarian and depends on the cause of the illness . Usually, medications such as antibiotics are given to fight bacterial infections and, if necessary, antivirals or drugs to strengthen the immune system.

Home remedies can also be used to relieve symptoms . Here are some examples:

  • Essential oils such as chamomile oil for inhalation to soothe the respiratory tract,
  • Regular cleaning of the nose and eyes to facilitate breathing,
  • and offering tasty or soft food to counteract loss of appetite. If the cat has difficulty drinking, fluid intake can be supported with a bottle.

For people who have theoretically contracted cat flu, treatment would be similar to that for a bad cold . This could include taking medication to relieve symptoms and strengthen the immune system. However, since transmission is extremely rare , the focus is mainly on prevention through good hygiene and protecting the immune system.

Cat flu vs. cold: The differences

Cat flu and a normal cold can have similar symptoms, but there are important differences. While a cold in humans is usually caused by rhinoviruses and is often harmless, cat flu can be very dangerous for the affected cat. Cat flu is caused by specific viruses and bacteria that only occur in cats.

The symptoms of a cold in humans typically include:

  • Cough.
  • Sniffles.
  • sore throat.
  • Mild tiredness.
  • In contrast, cat flu can cause the following, sometimes more serious, symptoms in cats:
  • Heavy nasal and eye discharge.
  • Frequent sneezing.
  • Ulcers in the oral cavity.


Fever and loss of appetite Another difference lies in the treatment . While colds in humans usually heal without special medication and only require relief of symptoms, cat flu often requires targeted therapy . This can include antibiotics against bacterial infections or even antiviral medication to effectively combat cat flu.

Distribution and History of Cat Flu

Cat flu is a common disease among cats and can occur anywhere where cats live in close proximity, such as in animal shelters or breeding farms. The history of the disease is closely linked to the domestication of cats. Cases of cat flu have been documented for centuries, which shows that the disease has long been a companion of the domestic cat.

The global spread of cat flu is mainly due to the close contact between cats and the high risk of infection. The main factors contributing to the spread include:

  • Uncontrolled contact with infected animals,
  • Lack of hygiene standards in animal shelters and breeders,
  • Delays in vaccination or missing vaccinations. These factors mean that cat flu is still a common and serious disease in cats today.

Myths about cat flu

Many people think that cat flu is just a harmless cold. But that's a myth . Cat flu is a complex viral infection that can cause serious health problems for your cat. It's important that you take this disease seriously and see a vet immediately if you notice any signs.

Another common misconception is that cat flu will heal on its own. While this can sometimes be the case, there is no guarantee. Here are some reasons why veterinary treatment is often necessary:

  • Cats can develop chronic symptoms ,
  • Without treatment, the condition may worsen,
  • Some cases require antibiotics or medications that strengthen the immune system.

In addition, some cat owners believe that cat flu only affects young or old cats. In fact, any cat, regardless of age, can become ill. And although vaccinations are sometimes considered unnecessary, they are extremely effective in preventing cat flu and should be given regularly.

If your cat has a cold, it can not only affect its health, but also take a toll on your emotions . Many cat owners develop a deep bond with their pets and see them as part of the family. Worrying about the sick animal can lead to stress and insomnia , especially if the treatment is lengthy or the cat is suffering.

The emotional stress can manifest itself in various forms:

  • Feelings of helplessness if the cat does not get better quickly enough.
  • Feelings of guilt if you believe you have not done enough for the animal's welfare.
  • Sadness or fear of a possible loss. It is important to take these feelings seriously and seek support when needed, whether through talking to friends, family or professional help.

Similar diseases and their symptoms

Cat flu presents symptoms such as sneezing, nasal discharge or sore eyes, which can also be seen in other cat diseases. For example, feline distemper , a very contagious viral disease, can cause vomiting, diarrhea and conjunctivitis. These symptoms can be similar to those of cat flu, which requires a precise diagnosis by the veterinarian.

In addition to feline distemper, there are other diseases that can have similar symptoms to cat flu. These include:

  • Feline leukemia , which can cause fever and loss of appetite.
  • Feline Infectious Peritonitis (FIP) , which is often accompanied by respiratory difficulties.
  • Parasite infestation , which can also cause coughing and sneezing

It's important not to ignore symptoms and act quickly if you suspect illness. Early diagnosis and treatment are crucial to help your cat and prevent potentially serious consequences. Make sure you schedule regular vet visits and get your cat vaccinated against common diseases to protect their health.
