Why is my cat coughing and sneezing?

Coughing is a protective instinct to clear the respiratory tract of corpuscles, mucus and microbes. Therefore, it is not a disease but rather a symptom and it is a symptom that often affects cats as well. Why is my cat coughing and sneezing? There can be many causes that trigger it: a little tickle in the throat, a slight irritation, a little pain and there it is, the first cough.
