Most commercial cat foods include fillers ranging from corn, soy, wheat, fruits and vegetables. Have you ever seen a cat eat bread or blueberries? Even commercial cat foods that are labeled as "healthy" contain fruit fillers that provide no nutrition for your cat. Food that is healthy for humans is not necessarily healthy for cats. Savage Cat Food is made up primarily of whole chicken and duck, including bones, hearts and livers. We add egg yolks for extra protein, as well as vitamins necessary for your cat's health. Psyllium husk is added to aid in digestion and salmon oil is added to attract your cat to the food.
