Palatability enhancers in cat food are ingredients added to increase a cat's interest in and appetite for the food. Common palatability enhancers include various meat or fish ingredients, such as chicken, beef, and fish. These ingredients add a delicious flavor to the cat food, making it more appealing to cats.

In addition, some cat foods contain yeast extracts, natural flavorings, and artificial flavorings, all of which have strong aromas and tastes that can attract a cat's attention. While palatability enhancers can increase a cat's interest in food, when choosing cat food, attention should also be paid to the quality and balance of other nutrients.
