Liver Care

The liver is your cat's largest internal organ with many functions, including the digestion and conversion of nutrients, the removal of toxic substances from the blood and the storage of vitamins and minerals. The liver has an amazing ability to repair and regenerate itself, and nutrition plays a vital role in this process.

Hill's nutritionists and veterinarians developed Prescription Diet® l/d®, clinical nutrition especially formulated to support your cat's liver health. In fact, l/d is formulated to help protect vital liver function.
