What causes a cat to cough suddenly, BESIDES a hairball, this is clearly not the sound of that.?

My 4 yr. old cat just suddenly yesterday started coughing (almost like a human cough that isn't dry). I will definitely call our vet tomorrow for an appt., but anyone had this happen to their cat? Do they get colds like we do? She seems fine otherwise, still fat as ever, eats well, just has these coughing... show more My 4 yr. old cat just suddenly yesterday started coughing (almost like a human cough that isn't dry).

She seems fine otherwise, still fat as ever, eats well, just has these coughing fits. I know the sound of a hairball cough and this isn't it. Thanks in advance!~
