There are many reasons why a cat's bottom might smell fishy. Generally, it's due to poor-quality cat food. It's recommended to switch to a different cat food, such as a natural one. Another possibility is that the fur around the cat's bottom is too long, causing it to accidentally get feces on it, resulting in a smelly bottom. Trimming the cat's fur is recommended. Using the same cat litter for a long time without changing it can also cause a smelly bottom; changing the litter regularly is advised.
Furthermore, cat odor contains hydrogen sulfide compounds, which can protect mitochondria in cells, making them less susceptible to diseases such as dementia, diabetes, and cardiovascular diseases. Studies have shown that cat owners have a 30% lower chance of developing heart disease than non-cat owners.
