Causes of cats sneezing continuously:

1. Allergy. Cats will be affected by allergens in the surrounding environment. Certain smoke or vapors in the air can make cats sneeze.

2. Cold. If a cat catches a cold due to cold weather or a large temperature difference, it is inevitable that the cat will sneeze. As long as the cat is kept warm, it will slowly recover.

3. There is a foreign body in the nasal cavity. Foreign matter enters deep into the nasal cavity and causes infection and irritation. Most of the time, it will be cured just by popping it out.

4. Inhalation of chemicals. If the cat litter is made with toxic chemical pigments and flavors, the cat will irritate the mucous membranes and cause frequent sneezing after inhaling these chemicals.

5. Rhinitis. Chronic rhinitis is common and develops slowly. Sneezing, runny nose, and secretions slowly develop into viscous thick fluid.
