Cat owners know for a fact that bad cat breath can be downright awful. It isn’t that much different from bad human breath, as both are caused by bacteria found in the mouth that breaks protein down and releases the sulfur compounds out into the air. Sulfur smells really bad on its own, which is why breath containing it smells bad as well. The bacterium that causes bad breath with cats is normally associated with a buildup of tartar around the teeth. Tartar is yellow in color, known as a coating of bacteria, food, and minerals.
To cure your cat from bad breath, you’ll need to remove the buildup of tartar. There are several cat foods out there that are designed to reduce the buildup of tartar, many containing enzymes that will literally dissolve it. You can also give your cat treats as well, as many of them will help eliminate and prevent tartar. If the buildup of tartar is bad, you may need to have your cat’s teeth professionally cleaned. Once the tartar has been removed, the bad breath will go away.
You may be able to clean the tartar off your cat’s teeth at home. There are several toothpastes available for pets, that come in a variety of flavors. You’ll need to get a battery powered toothbrush, as the motion is very important for removing tartar buildup. Most dry catfood will help eliminate the need to actually brush your cat's teeth, (something that I wouldn't even attempt with mine,) but if you feed your pet exclusively with canned, moist foods, you will definitely have to add crunchy cat treats specifically for tartar build up to his diet.
Sometimes, cats may have a bad odor in their mouth that doesn’t come from tartar or bad breath in general. In these rare cases, it can be either liver or kidney disease. If you notice bad breath and it isn’t tartar, you should take your cat to the vet - it’s better to be safe than sorry. Your veterinarian can pinpoint the problem, let you know what the cause is – and how you should go about fixing it.
