Understanding Respiratory Infections in Cats
Respiratory infections are a common health concern for cats, particularly when it comes to the upper respiratory system. Understanding the causes and risk factors associated with these infections is crucial for cat owners.
Causes of Upper Respiratory Infections
Feline upper respiratory infections are primarily caused by viruses, accounting for about 80%-90% of cases. The most common viruses responsible for these infections are feline herpesvirus type-1 (FVR) and feline calicivirus (FCV) (WebMD). These viruses can be found in the saliva, tears, and nasal secretions of infected cats, making them highly contagious.
In addition to viral causes, bacterial agents can also contribute to upper respiratory infections in cats. The most common bacteria associated with these infections are Bordetella bronchiseptica and Chlamydophila felis (VCA Hospitals). These bacteria can infect the respiratory system, leading to symptoms and complications.
Risk Factors for Respiratory Infections
Certain factors can increase a cat’s susceptibility to upper respiratory infections. Cats living in crowded conditions such as shelters, breeding facilities, or multi-cat households are at a higher risk due to close contact and shared environments (WebMD). Stress, poor nutrition, and concurrent diseases can also weaken a cat’s immune system, making them more susceptible to respiratory infections.
It’s important to note that cats can remain infective to other cats during the course of the infection. Therefore, proper hygiene practices should be followed to prevent the spread of respiratory infections among feline populations. For more information on preventing the spread of infections and caring for cats with respiratory issues, refer to the section on contagious nature of infections.

Specific Pathogens
When it comes to cat lung infections, several specific pathogens can be responsible for causing respiratory distress and other related symptoms. Understanding these pathogens is essential for proper diagnosis and treatment. In this section, we will explore two common pathogens associated with cat lung infections: Feline Herpesvirus (FVR) and Calicivirus (FCV), as well as Chlamydia Felis and Cryptococcus Neoformans.
Feline Herpesvirus (FVR) and Calicivirus (FCV)
Feline Herpesvirus (FVR) and Calicivirus (FCV) are responsible for approximately 90% of all feline upper respiratory infections. These viruses are highly contagious and can be transmitted through direct contact with infected cats or through respiratory secretions.
Feline Herpesvirus (FVR) causes upper respiratory signs, ulcers on the cornea (keratitis), and fever in cats (Cornell Feline Health Center). It is estimated that up to 97% of cats are exposed to FVR in their lifetime, with up to 45% shedding the virus when stressed. FVR can cause lifelong infection in up to 80% of exposed cats, making them carriers and potential sources of infection to susceptible cats.
Feline Calicivirus (FCV) is another highly contagious virus that causes upper respiratory signs, pneumonia, and, in severe cases, systemic symptoms leading to a two-thirds fatality rate (Cornell Feline Health Center). Approximately 10% of cats in small groups and up to 90% in crowded conditions may be infected with FCV. It is important to note that FCV carriers can shed the virus intermittently, even when they are not showing signs of infection.
Chlamydia Felis and Cryptococcus Neoformans
Chlamydia Felis, also known as Feline Chlamydiosis, is caused by the bacterium Chlamydia felis. This infection is transmitted through eye secretions and is common in young cats and those residing in high-density environments. Approximately 20% of cats with upper respiratory signs carry Chlamydia felis. Clinical signs primarily include conjunctivitis with eye discharge (Cornell Feline Health Center).
Cryptococcus Neoformans is a fungal infection that can affect cats and humans. In cats, it can cause nasal swelling, sneezing, chronic nasal discharge, and, in severe cases, spread to the lungs and other organs. Approximately 4% of cats are asymptomatic carriers of Cryptococcus Neoformans, which means they can harbor the fungus without showing any signs of illness.
Identifying the specific pathogens responsible for a cat’s lung infection is crucial for implementing appropriate treatment strategies. If you suspect that your cat may be suffering from a respiratory infection, it is essential to seek veterinary care promptly. Proper diagnosis, based on clinical signs, laboratory tests, and sometimes imaging, will guide the appropriate treatment and management of the infection.
