Understanding Feline Respiratory Infections
Feline respiratory infections are a common health concern among cats, often leading to discomfort and potential complications. Understanding the causes and transmission of these infections is crucial for effective prevention and treatment.
Causes of Feline Upper Respiratory Infections
The majority of feline upper respiratory infections are caused by viral or bacterial agents. Among these, feline herpesvirus type-1 (FVR) and feline calicivirus (FCV) are responsible for approximately 90% of all cases. Other less common agents include Bordetella bronchiseptica (B. bronchiseptica) and Chlamydophila felis (C. felis).
Feline herpesvirus and calicivirus are highly contagious and easily transmitted between cats. Cats can become infected through direct contact with infected cats or exposure to contaminated objects. The viruses can survive outside the host’s body for varying periods, with FVR surviving less than 18 hours and FCV potentially living up to ten days. Proper disinfection using a dilute bleach solution is effective against these pathogens (VCA Hospitals).
Spread and Transmission of Respiratory Infections
Feline upper respiratory infections are primarily transmitted through direct contact. Cats can become infected through activities such as touching, grooming, coughing, and sneezing. Additionally, these infections can spread through contaminated surfaces like food and water bowls, litter boxes, and bedding.
It’s important to note that cats infected with feline herpesvirus may carry the virus for life, even if they do not display symptoms. This means they can potentially spread the virus to other cats, including mother cats with new litters of kittens.
Certain factors can increase the risk of feline upper respiratory infections. Cats living in crowded conditions such as shelters, breeding facilities, or multi-cat households are more susceptible to developing these infections (WebMD). Implementing proper hygiene practices, regular vaccinations, and minimizing stress can help reduce the chances of infection.
By understanding the causes and transmission of feline respiratory infections, cat owners can take proactive measures to protect their feline companions. Regular veterinary care, vaccination, and maintaining a clean environment are essential for promoting respiratory health in cats. If you suspect your cat may have a respiratory infection, seek veterinary attention for proper diagnosis and treatment.
Symptoms and Complications
Recognizing the symptoms of feline upper respiratory infections is crucial for timely intervention and appropriate care. Additionally, understanding the potential complications that can arise from untreated infections is essential for ensuring the well-being of your feline companion.
Signs of Feline Upper Respiratory Infections
Feline upper respiratory infections are commonly caused by viral or bacterial agents, with feline herpesvirus type-1 (FVR) and feline calicivirus (FCV) being responsible for approximately 90% of all cases. Less common agents include Bordetella bronchiseptica (B. bronchiseptica) and Chlamydophila felis (C. felis) (VCA Hospitals).
Common symptoms of feline upper respiratory infections include:
- Sneezing
- Nasal congestion
- Conjunctivitis
- Discharge from the nose or eyes
- Ulcers in the mouth

Heart disease in cats can be present at birth (congenital) or acquired. Congenital heart diseases are relatively rare but occur when there is a malformed or defective heart structure. Some common types of congenital heart diseases in cats include:
- Atrial septal defect: A hole in the wall separating the heart’s two upper chambers.
- Ventricular septal defect: A hole in the wall separating the heart’s two lower chambers.
- Patent ductus arteriosus: A failure of a blood vessel, known as the ductus arteriosus, to close after birth.
Acquired heart diseases are more prevalent in cats. These conditions can develop over time and are often associated with aging or underlying health issues. Some common acquired heart diseases in cats include:
- Myocardial disease: Conditions that affect the heart muscle, such as hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM).
- Arrhythmias: Abnormal heart rhythms, including tachycardia (fast heart rate) and bradycardia (slow heart rate).
- Vascular (blood vessel) disease: Conditions that affect the arteries and veins, such as arterial thromboembolism (blood clot) and high blood pressure (hypertension).
- Heartworm infection: Infestation of heartworms, which can cause damage to the heart and lungs.
Common Lung Ailments in Felines
In addition to heart diseases, cats can also experience various lung ailments that can impact their respiratory health. While congenital lung diseases are relatively rare, acquired lung diseases are more prevalent. Some common lung ailments in cats include (Wag Walking):
- Asthma: A chronic condition characterized by inflammation and constriction of the airways, leading to breathing difficulties.
- Bronchitis: Inflammation of the bronchial tubes, which carry air to and from the lungs.
- Pneumonia: Infection of the lungs, often caused by bacteria, viruses, or fungi.
- Pulmonary calcification: The buildup of calcium deposits in the lung tissue, which can restrict breathing and lead to respiratory problems.
Diagnosing and treating heart and lung diseases in cats often requires a thorough examination by a veterinarian. Physical examinations and imaging techniques, such as X-rays, are typically employed to diagnose these conditions. In some cases, additional tests, such as cardiac catheterization or nuclear studies, may be necessary for a comprehensive understanding of your cat’s heart and lungs (Wag Walking).
By being aware of the types of heart diseases and common lung ailments that can affect cats, we can take proactive measures to safeguard our feline companions’ health.

Some common feline lung diseases include pyothorax, Feline Infectious Peritonitis (FIP), chylothorax, lymphoma, and hypertrophic cardiomyopathy.
Respiratory diseases are prevalent in cats, with respiratory tract problems being the most common cause of symptoms like coughing and labored breathing. However, these signs may also be due to disorders of other organ systems, such as congestive heart failure. Both very young and older cats are at an increased risk of developing respiratory diseases compared to healthy adult cats (Merck Veterinary Manual).
Factors contributing to lung diseases in cats can vary, and they may include:
Allergies and Irritants
Inhaled allergens and irritants can trigger respiratory problems in cats. These may include pollen, dust mites, mold spores, cigarette smoke, and certain cleaning chemicals. Cats with pre-existing allergies or sensitivities may be more susceptible to developing lung diseases when exposed to these triggers.
Infections
Respiratory infections caused by viruses, bacteria, fungi, or parasites can lead to lung diseases in cats. These infections can affect the upper respiratory tract, such as the nose and throat, or the lower respiratory tract, including the lungs. Kittens, elderly cats, and those with weakened immune systems are particularly vulnerable to infections.
Trauma and Injuries
Physical trauma, such as being hit by a car or experiencing a severe fall, can result in lung damage and respiratory problems in cats. Injuries to the chest or lungs can lead to pneumothorax (collapsed lung), hemothorax (blood in the chest cavity), or other complications that affect respiratory function.
Congenital Abnormalities
Some cats are born with congenital abnormalities in their respiratory system, such as tracheal collapse or cleft palate. These structural defects can impair normal breathing and increase the risk of developing respiratory disorders.
Tumors and Growths
Tumors or abnormal growths in the lungs or airways can obstruct airflow and compromise respiratory function. These growths may be benign or malignant and can lead to symptoms such as coughing, wheezing, or difficulty breathing.
Other Health Conditions
Certain underlying health conditions, such as heart disease or immune-mediated disorders, can contribute to respiratory problems in cats. These conditions may indirectly affect lung health and increase the risk of developing lung diseases.
Vulnerable groups for respiratory disorders in cats include very young kittens and older cats. Kittens have developing immune systems, making them more susceptible to infections and respiratory problems. Older cats may experience age-related changes in their respiratory system, which can make them more prone to respiratory diseases.
