I'll second that. One of my cats has breath bad enough to melt your face. Her name is Shaina but we often call her Princess Stinkles. She's in perfect health though!
Cats bad breath is just something that belongs to them. If cat is healthy. That means tooths are clean, tummy is ok and through than that is something you need to get used on.:-)
I have two bad mouth stinkers. :-D
