First check whether the weather is getting colder and the windows are open outside, causing the cat to catch a cold and sneeze; or if there is a pungent smell or fragrance in the home, which will cause the cat to sneeze frequently. If the cat catches a cold, the owner can give the cat medicine to treat the cold to avoid aggravating the condition; if the smell causes the cat, the owner can ventilate the room to relieve the cat's sneezing.
