Fats are a required macronutrient for both cats & dogs. Fats are a more concentrated fuel source, giving more than 2 x the number of Kilocalories per gram, compared to carbohydrates and proteins. They have many important functions including, serving as a carrier for fat-soluble vitamins, providing protection for vital organs and insulating the body to maintain temperature. Fats also enhance palatability and texture of the diet. Common sources of fat in a formulated whole food diet include animal fat, egg yolks, a variety of oils and Omega-3 Fatty acid supplementation. Every patient is an individual so the desired percentage of fat incorporated into the diet is based on a pet’s history, chronic disease processes, age, and current concerns. For pets with a chronic history of pancreatitis, or other similar disease processes, the types of fats are carefully selected and the percentage in the diet is reduced.
