Watery Eyes Symptom

There are many conditions that can cause watery eye discharge in cats:

  • Feline pneumonitis (Chlamydophila felis infection). Signs may range from watery to mucous- and pus-filled inflammation of the conjunctiva and mucous membranes of the nose.
  • Eyeworm disease (thelaziasis). Signs may include excessive watering of the eyes, inflammation of the conjunctiva, and slow-healing sores.
  • Blockage of the nasal duct (epiphora). Chronic overflow of tears due to an obstruction of the nasal duct is common in Persian and Himalayan breeds.
  • Feline infectious peritonitis
  • Acute bacterial and viral respiratory infections
  • Feline viral rhinotracheitis
  • Chronic nasal irritation
  • Feline herpes virus infection
  • Allergic reactions to environmental irritants
