There are many simple ways to get rid of bad breath in cats. Generally, brush your cat's teeth at least once a week using pet-specific toothpaste and a toothbrush to clean their teeth and reduce food debris and bacteria in their mouth, thus reducing bad breath. Avoid feeding them greasy and strongly flavored foods. Choose high-quality cat food that is rich in animal protein and has a mild flavor, as well as appropriate amounts of fruits and vegetables to promote digestive health and oral hygiene.

In addition, provide your cat with nutritionally balanced cat food, supplemented with appropriate amounts of meat and plant-based foods to ensure their nutritional needs are met. Furthermore, you can provide pet probiotics to help regulate gut flora and improve digestion.
