Good afternoon, I do not know if anyone has any idea what my cat might have (video on link below). I already took the 2 different vets and no one was able to say something in concrete, has already been x-ray and there is nothing to point. Was made the internal and external worming several times to eliminate options. He has days that do not cough, others barely wake up, and the first thing he does is to cough. Some coughs last less than 2 minutes, some more. Some times he vomits balls of hair, which I think is the cause of everything. But neither with malt paste and anti hair balls snacks, it gets better. He has had these crises since childhood. If anyone can help me, I appreciate it.
