Fussie Cat Premium is a formula that was developed by keeping a cats physiological make-up in mind. Including a wide array of essential vitamins and minerals, Fussie Cat Premium Tuna with Mussels starts with low- carb meat rich in necessary amino acids, proteins, and other nutrients. The place the food is made is as important as what your cats eat; thats why Fussie Cat uses an FDA-registered kitchen and follows AAFCO Cat food nutritional guidelines.
