Hi Sufiyan. The video is dark and not very clear. But it looks like a cough. If it's not very frequent, you can just ignore or if it's more, get him checked clinically. If cats want to throw up hairball, they retch and remove it out. This can also be monitored in stool, if you are finding lot of hair in stool, you can use any anti hairball paste or food accordingly.
