Raw diet and bad breath
Our kitten's been fed raw since the day we got him, and the older he's gotten (9 months now), the more we've noticed that his breath is really quite awful. This is our first cat on raw diet -- our previous cat was kibble-fed, and while his breath wasn't exactly minty fresh, it wasn't horrid either. Our new cat's breath, when we get a good whiff of it, is really pretty rotten.
He's been to the vet and his teeth and gums are "perfect." He's happy and healthy. We feed him lots of bones for his teeth. He's also done teething (we thought this might have been the culprit). Our vet said that sometimes cats just have bad breath, and ours might be one of those. And as long as he's healthy, it's really not a problem other than the occasional waft of odour, particularly when he's grooming!
What I'm curious about is whether there's any correlation between raw diets and cat breath. Given his dental hygiene is fine, it would seem to me that this is something more gastrointestinal. In all of your experience, do raw-fed cats usually have a noticeable difference in breath, either for the better or for the worse? We've been amazed at how much less stinky and hefty his poops are compared to our last cat, but he seems to be suffering a bit more on the other end.
And, for those of you experienced with raw diets, are there any particular culprits for bad breath or tips for fighting it?
