CN Critical Nutrition for Dogs and Cats by Purina ProPlan

Purina ProPlan Critical Nutrition is a canned diet that provides nourishment for dogs and cats recovering from illness or surgery. CN is formulated with key nutrients as well as high levels of fat and protein to support recovery, tissue repair and maintain body mass. It contains additional antioxidants to help reduce oxidative stress and encourage health and functions of the immune system. CN is easily digested and has a smooth texture for syringe or tube feeding.  Its high palatability makes CN ideal for dogs and cats with reduced appetite.
