why does my cat's breath smell so bad
What Could Be Causing My Cat's Bad Breath? Most often, bad breath is caused by a build-up of odor-producing bacteria in your petâs mouth. This can be a result of dental or gum disease; certain cats, in fact, may be especially prone to plaque and tartar. Diet and dermatological issues can also be contributing factors.
So when they groom themselves, the bad smell from their mouth transfers to their coat. If you have more than one cat, and that cat grooms others, it may also make the other cats smell bad. You will need to examine your cat's mouth and see if their breath might be the culprit. Bad breath is usually caused by tooth decay or can also be a sign of chronic illness such as kidney failure.
