The bad breath of most cats and dogs does not reach the level of being considered a disease. Many cats and dogs have bad breath, which is a normal phenomenon and is not related to viruses. The bad breath of cats and dogs is mainly caused by the following two reasons.

Common Causes of Cat Bad Breath
Bad Breath Caused by Gastrointestinal Indigestion
The bad breath of most cats is caused by indigestion of food in the gastrointestinal tract. Food ferments in the cat’s stomach for a long time, producing unpleasant odors. Some of these odors are expelled through flatulence, while the rest are expelled through the mouth, resulting in bad breath. The reasons for this situation may be excessive intake of cat food or snacks, too many varieties, or high protein content in the cat food.
Some low-quality foods contain poor-quality, spoiled meat and feather meal, which can cause gastrointestinal discomfort in cats, resulting in foul-smelling feces and bad breath. So, how can this problem be solved?
- Reduce the Protein Content of Cat Food: Choose cat food with a protein content not exceeding 38%, or brush your cat’s teeth. However, in reality, 99% of cats will not cooperate with you in brushing their teeth, and you also do not have that much time. Therefore, the most practical solution to your cat’s bad breath is to feed it dental water. High-quality dental water is colorless and odorless like water, and your cat will not notice it. It can effectively improve your cat’s bad breath problem in about a week.

Dental Calculus and Oral Problems
As cats and dogs age, they will develop a series of oral problems, the most common of which is dental calculus. My cat is already seven years old and has a thick layer of dental calculus in its mouth. Many pet owners will buy products such as dental chews and calculus freeze-dried to help cats remove dental calculus, but these methods are often ineffective. If the cat only has mild dental calculus, there is no need to worry too much. If the dental calculus is particularly severe, there are almost no other effective solutions besides teeth cleaning.
Bad Breath Caused by Oral or Gastric Injury
The second situation of cat bad breath is relatively rare, that is, damage to the cat’s oral cavity or stomach, and the odor produced by the decomposition of bacteria. In this case, cats and dogs may exhibit some symptoms, such as gastric ulcers and stomatitis. If you encounter this situation, it is recommended that you take your cat to the hospital for a visit.
