Background: ownership, sourcing and positioning
Hill's Science Diet and Trilogy offer two different approaches to the Australian cat food market. Hill's Science Diet faced a 2019 vitamin D over-supplementation recall on canned dog food that led to a US$12.5 million class-action settlement; cat food was not affected. Trilogy uses deliberately regional proteins including Northern Territory barramundi, outback kangaroo and Australian salmon alongside New Zealand lamb. The two brands take different paths to the same shelf, and those differences become clear once you look past the price tag.
Hill's Science Diet is made in the United States. It employs more than 150 in-house veterinarians and PhD nutritionists, and runs a veterinary-only clinical portal at myhillsvet.com.au.
Trilogy is built on a three-pillar philosophy of protein, grasses and water, translated into grain-free kibble with freeze-dried meat inclusions and wet food in bone broth.
