Fish with no species stated. The maker may use whatever is available, so the fish can change between batches. Nutritionally it is a fine protein and often a source of omega-3 fats. The gap is for pets with a known fish allergy, or whose owners are trying to track which protein causes a reaction, because an unnamed ingredient makes that very hard. Named fish such as salmon or whitefish give you that information.

Starch from the cassava root, used to bind kibble and as a carbohydrate source, especially in grain-free foods. It is nearly pure starch with little protein, fiber or micronutrients, and it is one of the least likely ingredients to trigger an allergy. A food that leans on tapioca for carbohydrate is getting easy digestibility and little else from it, which is fine as long as the rest of the recipe carries the nutrition.

A plant oil added as a source of linoleic acid, the omega-6 fat dogs and cats need for skin and coat. It is cheap, stable and well tolerated. Sunflower oil contains no omega-3, so a food that uses it as the main fat will usually add fish oil or flaxseed for balance. The high-oleic variety is lower in linoleic acid and used mainly for shelf stability.
