I am a first time cat owner and am worried. I got my kitten a couple of months ago and everything has been fine. But this evening when he was playing on a chair (he lies over the top of it so he can play with his tail) I heard a funny sound. I looked over and he was lying on the chair having trouble breathing. It kind of remnded me of what it would sound like if someone was choking on their food and lost their airway. I was freaking out and didn't know what to do, and then a minute later he was fine like nothing had happened. Is this what happens when they get a hairball, or does it sound like something really serious? I really appreciate any help.
