Please help! My 10 year old exotic Persian male cat has these coughing fits twice a week and they last up to a minute or longer. I have a video this time just because I caught him coughing. It's 45 seconds long. Around 3 years ago he has a mild case of bronchitis but they said that it just needs to be monitored at his yearly checkups. Nothing has come up since. Could this be something worse? Idk why I can't upload it on here. If you know how please tell me!
