Dietary indiscretion, food allergies, or lack of digestive enzymes can affect your cat's digestive health. Efficient digestion is essential for your cat to be able to build and repair tissues and obtain energy, and for these reasons it is important to feed a food that is formulated to help support digestive health. 
At Hill's, nutritionists and veterinarians have developed clinical nutrition especially formulated to help manage cats with digestive health problems. Due to its easily digestible ingredients, Prescription Diet™ i/d™ may also be helpful for cat recovering from gastrointestinal upset and routine surgery.
