Respiratory infections are common in cats and can be caused by a variety of pathogens, including viruses, bacteria, and fungi. Accurate diagnosis is crucial for appropriate treatment and prevention of complications. Here are the primary methods used to diagnose respiratory infections in cats:
1. Physical Examination
The initial step in diagnosing respiratory infections is a thorough physical examination performed by a veterinarian. The vet will assess your cat’s overall health, including body temperature, respiratory rate, and effort. They will examine the nose, mouth, and throat for any signs of inflammation, discharge, or abnormalities. Auscultation (listening) to the lungs with a stethoscope can help detect abnormal lung sounds, such as wheezing or crackles.
2. Blood Tests
Blood tests can provide valuable information about the underlying cause of a respiratory infection. A complete blood count (CBC) can reveal signs of inflammation or infection, such as elevated white blood cell counts. Blood chemistry panels can detect changes in organ function that may be associated with certain respiratory infections, such as elevated liver enzymes in cases of feline infectious peritonitis (FIP).
3. Nasal and Throat Swabs
Nasal and throat swabs are essential for obtaining samples to identify the specific pathogen responsible for the respiratory infection. These samples are collected using a sterile swab and sent to a laboratory for analysis. Culture and sensitivity testing can determine the type of organism causing the infection and its susceptibility to different antibiotics.
Additional Diagnostic Tests:
Depending on the severity of the respiratory infection or the suspected pathogen, additional tests may be necessary:
- Chest X-rays: Reveal abnormalities in the lungs, such as pneumonia or lung edema.
- Polymerase Chain Reaction (PCR) Test: Detects the presence of specific viruses or bacteria in respiratory secretions.
- Bronchoalveolar Lavage (BAL): A procedure involving the collection of fluid from the lungs to evaluate for cells and pathogens.
- Fungal Culture: Used to diagnose fungal respiratory infections, such as aspergillosis or cryptococcosis.
An accurate diagnosis is essential for directing appropriate treatment. By using a combination of physical examination, blood tests, and nasal/throat swabs, veterinarians can determine the underlying cause of respiratory infections in cats and initiate the most effective treatment plan.
Treatment of Respiratory Infections:
Respiratory infections are a common health concern for cats, causing symptoms such as sneezing, coughing, nasal discharge, and difficulty breathing. Treatment depends on the underlying cause of the infection, which can be either bacterial, viral, or fungal.
Antibiotics
Bacterial respiratory infections, such as pneumonia or bronchitis, are treated with antibiotics. Common antibiotics used in cats include amoxicillin, clavulanate, and enrofloxacin. The duration of treatment typically ranges from 7 to 14 days.
Antivirals
Viral respiratory infections, such as feline herpesvirus (FHV-1) and feline calicivirus (FCV), do not respond to antibiotics. Instead, antiviral medications are required. These medications include famciclovir, valacyclovir, and interferon. Antiviral treatment may shorten the duration of symptoms and prevent complications.
Decongestants
Decongestants help relieve nasal congestion and improve breathing. They are typically given as oral medications or nasal drops. Common decongestants used in cats include phenylephrine and pseudoephedrine. Decongestants should be used cautiously in cats with underlying heart conditions.
Bronchodilators
Bronchodilators relax the muscles in the airways, making it easier for cats to breathe. They are typically given as inhalers or nebulizers. Common bronchodilators used in cats include albuterol and terbutaline. Bronchodilators are most effective when used in conjunction with other treatments.

Brachycephalic Airway Syndrome (BAS):
Introduction:
Brachycephalic Airway Syndrome (BAS) is a complex respiratory disorder that affects cats with short, flat faces, known as brachycephalic breeds. These breeds include Persian, Himalayan, Exotic Shorthair, and British Shorthair cats. BAS arises from anatomical abnormalities in the airway that can lead to significant breathing difficulties.
Symptoms of BAS:
Cats with BAS exhibit a range of symptoms, including:
- Noisy breathing (stridor)
- Snorting or snuffling
- Dyspnea (difficulty breathing)
- Cyanosis (bluish tint to gums and tongue)
- Gagging or retching
- Exercise intolerance
- Snoring
- Weight loss
Diagnosis of BAS:
Diagnosing BAS involves a thorough physical examination, medical history, and various diagnostic tests:
- Physical Examination: Your veterinarian will examine your cat’s head, neck, and chest, paying attention to the shape of the muzzle, nostrils, and trachea.
- Imaging: X-rays or computed tomography (CT) scans can visualize the airway and identify any abnormalities.
- Laryngeal Endoscopy: A small camera is inserted into the larynx (voice box) to inspect the vocal cords, epiglottis, and other airway structures.
Surgical Treatment Options for BAS:
If medical management fails to improve a cat’s respiratory symptoms, surgical intervention may be necessary. Several surgical techniques are available to address the underlying anatomical abnormalities:
1. Nares Flap Surgery:
* This procedure widens the nostrils to improve airflow.
* A small flap of tissue is created in the nostrils and surgically secured.
2. Tracheal Resection and Anastomosis (TREA):
* Involves removing a portion of the collapsed trachea and reconnecting the healthy ends together.
* The scar tissue that forms around the newly connected trachea helps prevent further collapse.
3. Laryngeal Ventriculectomy and Arytenoid Lateralization:
* This surgery involves removing a section of the laryngeal ventricles and adjusting the arytenoid cartilages (which control the vocal cords).
* It helps widen the airway and reduce airway resistance.
4. Palatal Resection:
* If the soft palate is excessively long and obstructs the airway, a portion may be surgically removed.
5. Bulla Removal:
* In some cases, BAS can be caused by the presence of bullae (air-filled cysts) in the lungs. These cysts can be surgically removed to improve lung function.
Conclusion:
Brachycephalic Airway Syndrome is a serious respiratory disorder that can significantly impact a cat’s quality of life. Early diagnosis and appropriate treatment are crucial to manage BAS and ensure your feline companion’s well-being.
