Trout patties contain whole fresh trout. Our Steelhead are farmed but they are raised in clear, cool lakes fed by the pristine waters of the Rocky Mountains. This superior environment produces healthy fish! On average less than 0.02% of feed fed to the Steelhead contains any form of therapuetants so it’s safe to feed your dog or cat. Both the fish and their environment are monitored regularly during the production process to ensure they meet strict quality standards.
