Respiratory infections are fairly common in cats, especially in outside or feral cats. You may notice excessive sneezing, eye and nasal discharge, lethargy, weight loss and coughing as an indication of a respiratory infection. A variety of viruses, bacteria infections, and fungal infections are the most common causes of upper and lower respiratory issues. These are readily treatable when diagnosed soon after your cat starts showing symptom.  Other respiratory issues are:

  • Breathing difficulties, short face: Manageable Condition/Serious Problem
  • Chronic sinus problems: Manageable Condition
  • Nasal obstruction: Serious Problem
  • Fungal infections: Manageable


Prevention through vaccination is the primary path. Most problems can be cured or controlled through medication, however more serious structural problems may require surgery.
