Feline Upper Respiratory Infections
Feline upper respiratory infections are common in cats and can cause discomfort and health complications. These infections primarily affect the upper airway, including the nose, throat, and sinuses, rather than the lungs. The most common causes of feline upper respiratory infections are viral or bacterial agents, with feline herpesvirus type-1 (FVR) and feline calicivirus (FCV) being responsible for approximately 90% of cases (VCA Hospitals).
Common Causes
Feline upper respiratory infections are primarily caused by viruses, accounting for about 80% to 90% of infections. Bacterial infections make up the remaining cases. The most prevalent viral agents are feline herpesvirus type-1 (FVR) and feline calicivirus (FCV). These viruses are highly contagious and can spread rapidly among cats, particularly in multi-cat environments. Other less common viral agents include mycoplasma or feline reovirus (VCA Hospitals).
Transmission Sources
Feline upper respiratory infections can be transmitted through various sources. Direct contact with an infected cat, particularly through sneezing or coughing, is a common mode of transmission. Additionally, sharing food bowls, litter boxes, or close living quarters can facilitate the spread of the infection. Contaminated objects, such as bedding or toys, can also serve as sources of transmission. It’s important to note that humans cannot contract feline upper respiratory infections, as these infections are specific to cats.
To protect your cat from upper respiratory infections, it’s essential to keep them away from infected cats and minimize exposure to shared resources in high-risk environments. Regular vaccination, as recommended by your veterinarian, can also help in preventing certain viral infections that cause upper respiratory problems in cats.

Viral and Bacterial Agents
Feline upper respiratory infections are commonly caused by viral or bacterial agents, with two primary culprits being feline herpesvirus type-1 (FVR) and feline calicivirus (FCV). According to VCA Hospitals, these two viruses are responsible for approximately 90% of cases, while less common agents include mycoplasma or feline reovirus.
Feline Herpesvirus Type-1 (FVR)
Feline herpesvirus type-1 (FVR), also known as feline viral rhinotracheitis, is a highly contagious virus that affects the upper respiratory system of cats. It can cause symptoms such as sneezing, nasal discharge, conjunctivitis, and coughing. Infected cats shed contagious particles in their saliva or secretions from the nose or eyes, making transmission to susceptible cats easy. Direct contact with an infected cat or exposure to contaminated objects can lead to an infection.
FVR is not only highly contagious but can also persist in the environment for a limited time. The virus can survive less than 18 hours outside the host’s body. To help prevent the spread of FVR, thorough cleaning and disinfection of contaminated areas are essential. A diluted bleach solution can effectively destroy the virus, but it’s important to note that feline calicivirus (FCV) is more resistant to bleach-free laundry detergents. For more information on preventing and managing FVR, consult your veterinarian.
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 spreads through direct contact with infected cats or exposure to contaminated objects. Cats infected with FCV may experience symptoms such as sneezing, nasal discharge, oral ulcers, and joint pain.
Unlike FVR, FCV can survive in the environment for a longer period, up to ten days. The virus can withstand washing with bleach-free laundry detergents, so extra precautions may be necessary to prevent transmission. Vaccination against FCV is available and can help reduce the severity and duration of the infection.
Both FVR and FCV can cause a carrier state in cats, with female carriers capable of passing the infection on to their newborn kittens. It’s important to seek veterinary care if you suspect your cat is infected to receive an accurate diagnosis and appropriate treatment. Veterinary professionals can provide guidance on managing the infection and preventing its spread within multi-cat households or high-risk environments.
Understanding the viral and bacterial agents involved in feline upper respiratory infections, such as FVR and FCV, can help cat owners take necessary precautions to protect their feline companions and limit the spread of these infections. Regular veterinary check-ups, vaccination, and proper hygiene practices are key to maintaining the health and well-being of cats.

Treatment and Management
When it comes to addressing respiratory problems in cats, treatment and management strategies play a crucial role in alleviating symptoms and promoting recovery. The two main aspects of treatment and management are symptomatic treatment and preventive measures.
Symptomatic Treatment
Most cats with uncomplicated upper respiratory infections can be treated symptomatically at home, allowing for a comfortable recovery. The duration of recovery can vary, with most cats experiencing improvement within 7-10 days, although symptoms may persist for up to 21 days. It is important to note that carriers of feline herpesvirus type-1 (FVR) will have the disease for life, while carriers of feline calicivirus (FCV) may have the disease for a few months to life. Persistent carriers are usually asymptomatic but can transmit the disease to susceptible cats (VCA Hospitals).
Symptomatic treatment for upper respiratory infections typically involves:
- Broad-spectrum antibacterial drugs: These are prescribed to prevent secondary bacterial infections that may occur in cats with uncomplicated upper respiratory infections.
- Increased environmental humidification: Cats with nasal congestion may benefit from increased humidity in their surroundings. Taking them into a steamy bathroom for 10-15 minutes several times a day can help relieve congestion.
- Nose drops: In severe cases with excessive nasal discharge or painful nasal tissues, nose drops may be recommended to provide relief (VCA Hospitals).
In some cases, severe respiratory infections may require intensive treatment and hospitalization under the guidance of a veterinarian. It is important to promptly seek professional advice when a cat’s respiratory symptoms worsen or if they exhibit signs of distress. For emergency situations, it is recommended to consult a veterinarian experienced in cat emergency veterinary care.
Preventive Measures
Preventing the transmission of respiratory infections is crucial in managing the overall health of cats. Here are some preventive measures to consider:
- Environmental hygiene: Feline herpesvirus type-1 (FVR) can survive for less than 18 hours outside the host’s body, while feline calicivirus (FCV) may persist for up to ten days. Regular cleaning and disinfection using a dilute bleach solution can help destroy these viruses. However, it is important to note that calicivirus can withstand washing with bleach-free laundry detergents (VCA Hospitals).
- Incubation period awareness: Once a cat is exposed to an infectious agent, there is an incubation period of 2-10 days before clinical signs develop. During this time, the cat may be infective to other cats. Being aware of this period can help prevent the spread of respiratory infections by isolating potentially infected cats or taking appropriate precautions (VCA Hospitals).
By implementing proper symptomatic treatment and preventive measures, cat owners can effectively manage and control respiratory problems in their feline companions. It is essential to consult with a veterinarian for a comprehensive diagnosis and tailored treatment plan based on the specific condition and needs of the cat.
