Understanding Feline Respiratory Infections
Feline respiratory infections are common among cats and can cause discomfort and distress. These infections can be caused by both viral and bacterial agents, each with its own characteristics and implications.
Viral vs. Bacterial Causes
Viral infections account for approximately 80%-90% of feline respiratory infections, with bacteria causing the remaining cases. The most common viral agents responsible for these infections are feline herpes virus (FHV) and feline calicivirus (FCV), as mentioned by PetMD. These viruses are highly contagious and easily spread through direct contact, such as grooming, coughing, and sneezing, as well as through contaminated surfaces like food and water bowls or litter boxes WebMD.
Bacterial infections, although less common, can also contribute to feline respiratory infections. Bacteria such as feline bordetella, chlamydophila, mycoplasma, and cryptococcus can cause respiratory symptoms in cats PetMD. It’s important to note that viral and bacterial infections can occur simultaneously, leading to more severe symptoms and complications.
Transmission and Risk Factors
Feline respiratory infections are highly contagious and can easily spread from one cat to another. Infected cats shed contagious particles in their saliva, as well as secretions from the nose and eyes. Susceptible cats can become infected through direct contact with an infected cat or through environmental exposure to contaminated objects VCA Canada.
Certain factors can increase the risk of cats developing respiratory infections. These include:
- Stress: Cats that are stressed or have weakened immune systems are more susceptible to infections.
- Crowded Living Conditions: Cats living in close quarters, such as shelters or multi-cat households, have a higher risk of exposure to respiratory pathogens.
- Young Age: Kittens, particularly those under six months old, are more vulnerable to respiratory infections due to their immature immune systems.
- Poor Ventilation: Inadequate airflow and ventilation in living spaces can contribute to the spread of respiratory infections.
By understanding the different causes and modes of transmission, cat owners can take necessary precautions to minimize the risk of respiratory infections in their feline companions. Regular veterinary care, vaccination, and proper hygiene practices play a crucial role in preventing and managing these infections.

Understanding these agents is crucial for proper diagnosis and treatment.
Feline Herpes Virus (FHV)
Feline herpes virus (FHV), also known as feline rhinotracheitis, is a highly prevalent virus in cats. Up to 97% of cats may be exposed to FHV in their lifetime, with approximately 80% of exposed cats experiencing lifelong infection. Stress can trigger periodic shedding of the virus in up to 45% of infected cats (Cornell Feline Health Center).
Clinical signs of FHV infection include upper respiratory symptoms such as sneezing, nasal discharge, and conjunctivitis. Cats with FHV may also develop ulcers on the cornea (keratitis) and experience episodes of fever. While there is no cure for FHV, supportive care, including proper nutrition and management of secondary infections, can help manage the symptoms. Vaccination against FHV is a crucial preventive measure to reduce the severity and frequency of outbreaks.
Feline Calicivirus (FCV)
Feline calicivirus (FCV) is another common cause of upper respiratory infections in cats. It is highly contagious, with approximately 10% of cats in small groups and up to 90% in crowded conditions being infected. FCV can cause a range of clinical signs, including upper respiratory symptoms, pneumonia, oral ulcers, and, in severe cases, systemic disease that can be fatal in about two-thirds of affected cats (Cornell Feline Health Center).
Vaccination against FCV is an essential preventive measure, particularly in multi-cat households or environments with a high population density. Vaccines can help reduce the severity of symptoms and the risk of transmission. Supportive care, including proper nutrition, hydration, and management of secondary bacterial infections, plays a significant role in the treatment of FCV-infected cats (Cornell Feline Health Center).
