Ingredient Review

Our review of Hill's Science Diet Adult Perfect Digestion Salmon Dry Cat Food begins with a detailed look at the food’s ingredients.

The first ingredient is Salmon. Salmon is meat from any fish in the salmon family, and in pet food, salmon might also refer to other parts of the fish including skin and organs. Salmon is an excellent source of protein, and it is a good source of Omega-3 fatty acids.

The second ingredient is Brown Rice. Brown rice is a name for whole-grain rice with its outer hull removed. The brown rice in pet food can be a source of carbohydrates and fiber. Brown rice also contains omega-6 fatty acids, vitamins, and minerals

The third ingredient is Corn Gluten Meal. Corn gluten meal is produced as a byproduct from the manufacture of corn syrup and other sweeteners made with corn. It contains no wheat gluten. The corn gluten meal in pet food is a source of inexpensive protein, but it has high levels of cysteine, which have been linked to the formation of urinary stones.

The fourth ingredient is Whole Grain Oats. Whole grain oats have had their tough outer hulls removed before further processing into a coarse high-fiber substance, complete with nutritious bran. The whole grain oats in pet food are a source of carbohydrates, protein, vitamins, minerals to support your companion’s overall well-being.

The fifth ingredient is Potato Protein. Potato protein is an isolated protein that comes from potatoes. In pet food, potato protein is used as a low cost protein source as well as an emulsifier and texture-enhancing agent.

When we analyzed the ingredients in Hill's Science Diet Adult Perfect Digestion Salmon Dry Cat Food, we found that most of the protein is derived from plant based sources.
