Why Does My Cat’s Breath Smell Like Fish?

We all know cats have unique smells, but when their breath starts to smell like fish, it can be quite concerning. There can be several reasons why your cat’s breath might have this fishy odor, ranging from simple issues to underlying health problems.

1. Poor Dental Hygiene: One of the most common reasons for fishy breath in cats is poor dental hygiene. Tartar buildup, gum disease, and tooth decay can all contribute to a foul smell in your cat’s mouth.

2. Diet: Certain types of cat food can also cause fishy breath. Some brands use fish as a primary ingredient, and the lingering scent can affect your cat’s breath. Additionally, if your cat has been eating fish-based treats or raw fish, it can contribute to the smell.

3. Kidney Disease: A more serious cause of fishy breath is kidney disease. When the kidneys are not functioning properly, waste products can build up in the bloodstream, leading to a distinctive odor in the breath.

4. Diabetes: Cats with uncontrolled diabetes may have a sweet or fishy odor to their breath. This is due to the body’s inability to properly process glucose, resulting in a byproduct called ketones, which can produce an unpleasant smell.

5. Respiratory Infections: Respiratory infections, such as sinusitis or gingivitis, can cause a fishy smell in your cat’s breath. These infections may be accompanied by other symptoms like sneezing, coughing, or nasal discharge.

6. Gastrointestinal Issues: Certain gastrointestinal problems, such as gastric reflux or intestinal obstructions, can lead to smelly breath in cats. These issues can cause regurgitation or vomit, which can leave a foul odor in the mouth.

7. Liver Problems: Liver disease or dysfunction can also cause an unusual odor in your cat’s breath. When the liver is not functioning properly, toxins build up in the body, leading to a distinctive smell.
