I have had my shelter cat for almost 2 years. I've noticed if he gets really excited when purring he kinda chokes then coughs. I give him hairball meds daily and brush him so I don't think it's a hairball. But it concerns me when it happens. He is a very health inside cat other than that. I don't have a lot of money so can't really afford tests and extracts. Just wondering if other parents have experienced anything similar.
