PHYSIOLOGICALLY TUNED MEAT FIRST, POTATO AND GRAIN FREE SUPER PREMIUM FOOD for catS. While it's perfectly safe to stop feeding your cat's previous food one day and introduce Fussie Cat the next, we recommend a gradual transition to Fussie Cat for up to two weeks. This is especially true if your cat has been previously fed a high grain, corn, wheat, or soy diet. Start by introducing a small amount of Fussie Cat, increasing it daily while decreasing the previous food by the same amount. This will help avoid upset stomachs, as it makes it easier for your pet's digestive system to acclimate. Formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for All Life Stages.
