Top Questions

How much should I feed my pet?

Just as eating amounts vary from person to person, eating amounts vary from pet to pet. Most Hill's® Science Diet® pet foods have a feeding guide on the package to help you determine the proper amount to feed your pet. However, the feeding guide is intended only as a starting point. It's critical to your pet's health that his or her physical condition be monitored regularly and the feeding amount adjusted as needed. To access the suggested feeding guide for the Hill's® brand pet food that you feed your pet, refer to our product selector.
