Bynx has always coughed or wheezed, at least even since I can remember. I'm actually not sure what to call it? He extends his neck and makes this god awful noise. I have tried to watch videos of cat's coughing or wheezing but none of them sound the same. I am just worried it could be HCM. I have read coughing is a rare symptom, but I can't wrap my head around what it is. He doesn't cough everyday, or even every week. He does it maybe like once a month, some weeks more than others. In the past couple weeks he's done it twice. He has had watery eyes before, but my friend (vet nurse) has said it's just allergies and there isn't much to do. His eyes have been better recently though. If your babies have cat asthma, does this sound familiar? Last time I took him to the vet (because he was puking and not going potty) they took an x-ray of this stomach/chest and found nothing. I am hoping if something was wrong with his heart they would have said something.
