Bad breath — it happens to the best of us, including our beloved feline companions. Although many cases of our morning breath can be solved with a morning brush routine, cat bad breath often indicates a more serious medical problem, with both oral causes or systemic ones.
According to International Cat Care, 85% of cats have some form of dental disease, and it's no wonder why. A cat's teeth and gums (aka gingival tissue) have naturally occurring bacteria. As these germs multiply and aren't removed via brushing, they can develop a bacteria plaque film on the teeth; this film hardens through natural minerals in your cat's saliva and becomes tartar. The bacteria in your cat's mouth that are not removed release smelly compounds after they breakdown leftover food particles. Not only does this cause cat bad breath, but mouth bacteria can travel via the blood to various organs, where they can cause infections throughout the body, often resulting in heart and kidney disease. The accumulation of tartar also forces the gums down, causing them to recede, which loosens the roots of the teeth. Eventually, those loose teeth fall out. This all makes for one stinky and painful kitty mouth.
Cats also can expose their teeth and gums to foreign objects — from bugs they catch and eat to nonfood objects that can cause injury or oral trauma. In addition to these sources, cats are known for their frequent hairballs and vomiting. Imagine how foul your breath would become if you couldn't clean your mouth after being sick and you begin to understand why cat bad breath develops.
Further oral causes of halitosis (the scientific name for bad breath) in cats include oral tumors, abscesses from dead teeth and inflammatory gum conditions.
The source of cat bad breath can't always be traced to the mouth. Some of the more common systemic causes of bad breath in cats are serious medical conditions that necessitate prompt medical treatment.
As you can see, bad breath in cats is anything but a frivolous and smelly inconvenience. While bad breath in people can be related to nonserious causes, such as eating garlicky food, bad breath in cats is more often a longstanding and serious condition. Luckily, there is often a solution.
