Take into consideration the AAFCO statement

The Association of American Feed Control Officials, also known as AAFCO, is a statement that indicates the fact that food is good and complete for animals. 

According to cat specialist Brittany Carey, “instead of sweating over the ingredient list, pay attention to the nutrients in your cat food. Look for a statement from the Association of American Feed Control Officials (AAFCO) saying that the food is complete and balanced.”
