ThriveTuna with Vegetable Complete Wet Cat Food

A fish used mostly in cat foods, where its strong flavor is the point. Tuna is a good protein and a source of omega-3 fats. Two cautions apply to tuna fed often: it is higher in mercury than smaller fish, and cats can become fixated on it and refuse other foods. Both cautions apply to the cat eating tuna every day, and much less to tuna as one ingredient in a complete food fed in rotation.

A vegetable that contributes a little fiber and beta-carotene and a lot of label appeal. In dry food it is usually present in small amounts well down the list. It is not an allergen of concern and not a meaningful protein or calorie source. Fine to see; not a reason to choose one food over another.

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.
