Analytical Constituents and Guaranteed Analysis

Under European Law, pet food manufacturers are required to list analytical constituents on cat and dog feeds, supplements and treats. These values represent the minimum or maximum (depending on the nutrient) content as a percentage. This is similar to the Guaranteed Analysis listed on American pet foods.

See below for some examples of how these values are listed on pet food/treats packaging.
