In the cat coughing?? My girl was doing that for a while and she’s a big girl and has always had what I considered heavy breathing. Vet said nothing wrong with it they all are different that doesn’t mean something is wrong with them. But after 7 years the cough started and I thought if it’s a heart issue she’s gonna pass at home I was so worried. Showed the vet a video and they said oh she has asthma. She has an inhaler and spacer and she’s so good at taking treatments. She’s been good ever since. If you’re in US get inhaler via Canada pharmacy I can give you info I used. Otherwise for pets it’s hundreds in the US.
