Antibiotics, a vaporizer, allergy medications, dislodging a foreign object and surgery treats a sneezing cat, states HowStuffWorks. Treatment depends on the cause of the sneezing.
Antibiotics treat a sneezing cat if feline herpes virus-1 is the cause, notes HowStuffWorks. A vaporizer may also be used during this time to clear the cat’s respiratory system. Allergy medications remedy sneezing if it is determined that environmental allergens such as pollen are the cause. A cat sneezes until a foreign object is removed from its nostril, so removing the object may eliminate the sneezing. Surgery removes polyps in the nose that may cause a cat to sneeze.
