GUARANTEED ANALYSIS

A “guaranteed analysis” is required by FDA and BAI to show the minimum and maximum percentages of nutrients from a specific brand or manufacturer. This test analyzes the amount of crude protein, crude fat, crude fiber, moisture, and ash in every batch of cat food. Manufacturers must include these nutrients, although other nutrients are not mandated.

In cat food, the amino acid taurine and the mineral magnesium are often listed, because these are essential to cats. Moreover, ash content for cat food should ideally be low.
