According to research published in the ‘Journal of the American Veterinary Medical Association’, fat in the diets of companion animals like dogs and cats plays a role in contributing to the palatability and texture of food. This is obviously a critical function because no pet food, regardless of how well-formulated it is, can be nutritious if the pets don’t eat it! As the fat content increases, so does the energy density of the diet. Portion-controlled feeding is usually the best method when feeding a well-balanced, energy-dense pet food containing moderate to high levels of fat.
