After your wife makes you spend a couple nights on the couch for suggesting the demise of fluffy, they do make a breath freshening foam that seems to work fairly well. My wife has two cats that I would love to send somewhere else, but the dogs can’t get access to the sand covered treats. They still both get god awful breath from eating things like deer crap, raccoon crap, rabbit crap, and pretty much any other critter crap they can find. The foam seems to work pretty well. Neither dog likes it, but contrary to what they seem to like to think, I’m the alpha and they get to eat the foam whether they like it or not.
