Here's why:
* Taurine is essential for cats. It plays a vital role in many bodily functions, including vision, heart health, and reproduction. Cats can't produce taurine on their own and must get it from their diet.
* Fish is a good source of taurine. It contains high levels of this crucial amino acid, making it particularly appealing to cats.
* The strong odor of fish. The smell of fish, particularly oily fish like salmon and tuna, can be very strong and stimulating to cats' olfactory senses. This attracts them to the food source.
While the smell of fish is a primary draw, the taste and texture of fish are also contributing factors to a cat's enjoyment of this food source.
