Understanding Cat Flu
Feline respiratory infections, commonly known as cat flu, are a group of contagious diseases that affect the upper respiratory system of cats. To effectively prevent and manage these infections, it is important to understand their causes and the risk factors associated with them.
Causes of Feline Respiratory Infections
Feline upper respiratory infections are primarily caused by viruses, which account for about 80%-90% of cases, with the remaining infections being bacterial in origin. The most common viral agents responsible for cat flu are feline herpesvirus type-1 (FVR) and feline calicivirus (FCV) (VCA Canada). These viruses are easily spread through direct contact between cats, such as grooming, coughing, and sneezing. They can also be transmitted through contaminated surfaces like food and water bowls or litter boxes (WebMD).
Risk Factors for Cat Flu
Certain factors can increase a cat’s susceptibility to feline respiratory infections. Cats living in crowded conditions like shelters, breeding facilities, or multi-cat households are at a higher risk of developing upper respiratory infections. Stress, poor nutrition, and other underlying health conditions can also weaken a cat’s immune system, making them more susceptible to infections.
The viruses and bacteria that cause feline upper respiratory infections are highly contagious. Infected cats shed contagious particles in saliva or secretions from the nose or eyes, making it easy for susceptible cats to contract the infection through direct contact or environmental exposure to contaminated objects (VCA Canada).
It is important to note that once a cat is exposed to an infectious agent, there is an incubation period of 2-10 days before the development of clinical signs of a feline upper respiratory infection. The infection typically lasts for 7-10 days, but signs may persist for up to 21 days, during which time cats may remain infective to other cats.

Common Viral Agents
Feline upper respiratory infections, commonly known as cat flu, are primarily caused by viral or bacterial agents. Two common viral agents responsible for approximately 90% of cases are feline herpesvirus type-1 (FVR) and feline calicivirus (FCV) (VCA Canada). Let’s take a closer look at each of these viral agents:
Feline Herpesvirus (FVR)
Feline herpesvirus type-1 (FVR) is a highly contagious virus that affects the upper respiratory system of cats. It can be transmitted through direct contact with infected cats, through contaminated objects, or through aerosolized respiratory secretions (VCA Canada). The virus can survive less than 18 hours outside the host’s body.
Once a cat is exposed to FVR, it goes through an incubation period of 2 to 10 days before clinical signs of the upper respiratory infection develop. The infection typically lasts for 7 to 10 days, with symptoms possibly persisting for up to 21 days. During this time, cats may remain infective to other cats.
Feline Calicivirus (FCV)
Feline calicivirus (FCV) is another common viral agent responsible for feline upper respiratory infections. Similar to FVR, FCV is highly contagious and can spread through direct contact or aerosolized respiratory secretions. The virus can survive outside the host’s body for up to ten days, increasing the risk of transmission (VCA Canada).
FCV can cause a carrier state in cats, with female carriers able to pass the infection on to their newborn kittens. This carrier state contributes to the persistence and spread of the virus in feline populations. Vaccination against FCV is crucial to help prevent the transmission and severity of the infection.
To protect cats from feline herpesvirus (FVR) and feline calicivirus (FCV), vaccines are available. These vaccines are considered part of the standard core vaccines for cats and are typically administered in combination with other important vaccines. Regular boosters every one to three years are necessary to maintain immunity (VCA Canada). For more information on cat flu vaccines, you can visit our article on cat flu vaccine.
By understanding these common viral agents responsible for feline upper respiratory infections, cat owners can take preventive measures and seek appropriate treatment when necessary. If your cat shows signs of a respiratory infection, such as sneezing, nasal discharge, or coughing, it’s important to consult a veterinarian for an accurate diagnosis and treatment plan.
Uncommon Bacterial Agents
While feline upper respiratory infections are commonly caused by viral agents such as feline herpesvirus type-1 (FVR) and feline calicivirus (FCV), there are also less common bacterial agents that can contribute to these infections. It’s important to be aware of these uncommon bacterial agents in order to effectively address and manage feline respiratory infections.
Mycoplasma and Feline Reovirus
Mycoplasma and feline reovirus are two of the less common bacterial agents associated with feline upper respiratory infections. Mycoplasma is a type of bacteria that can cause respiratory symptoms in cats. It is often found in cats living in high-density environments, such as shelters and breeding catteries.
Feline reovirus is another uncommon bacterial agent that can contribute to respiratory infections in cats. Reovirus infections are usually mild and self-limiting, but they can occasionally lead to more severe symptoms.
While these bacterial agents are less common compared to viral causes, they can still play a role in feline respiratory infections. If your cat is experiencing persistent or severe respiratory symptoms, it’s important to consult with a veterinarian for proper diagnosis and treatment.
Bordetella and Chlamydophila
Bordetella bronchiseptica and Chlamydophila felis are two additional bacterial agents that can contribute to feline upper respiratory infections.
Bordetella bronchiseptica is a bacterium that can cause respiratory symptoms in cats. It is highly contagious and often associated with kennel cough in dogs. Cats can become infected with Bordetella bronchiseptica through close contact with infected animals.
Chlamydophila felis, on the other hand, is a bacterium that specifically affects cats. It is commonly found in young cats and those living in high-density environments such as shelters and breeding catteries. Infection with Chlamydophila felis can cause conjunctivitis with eye discharge, as well as other respiratory symptoms.
While these bacterial agents are not as common as viral causes, they can still contribute to feline upper respiratory infections. If your cat is showing signs of respiratory illness, it’s important to consult with a veterinarian for proper diagnosis and treatment.
By being aware of both the common viral agents like FVR and FCV, as well as the less common bacterial agents such as mycoplasma, feline reovirus, Bordetella, and Chlamydophila, cat owners can be better equipped to recognize and address feline respiratory infections. It’s essential to consult with a veterinarian for accurate diagnosis and appropriate treatment tailored to your cat’s specific needs.
