I know this is a chicken forum but I don't trust anyone else. We have a young rescue cat and he's been kicking butt. He's our first cat. Takes care of the mice and poops outside he's awesome. Last few days he's been caughing. I googled a few things which is always a bad idea and my best diagnosis is kennel caugh but who knows. Any suggestions? He had shots at the shelter when we got him 6 months ago does he need more? Thanks!
