Monterey Medley Skipjack Tuna & Mackerel Dinner in Gravy Wet Cat Food

Fish broth is used in pet food primarily as a flavor and moisture enhancer, providing modest amounts of fish-derived protein, amino acids, minerals and sometimes trace omega‑3s but not serving as a primary source of complete nutrition. It can improve hydration and entice picky, senior, or ill dogs and cats to eat, but caregivers should watch for high sodium, added seasonings (especially onion or garlic), potential fish allergies, and variable quality depending on processing.

Skipjack (skipjack tuna) is used in dog and cat foods as a highly palatable fish protein and flavor source, supplying complete amino acids, omega‑3 fatty acids (EPA/DHA) for skin, coat, joint and cognitive support, and trace minerals such as iodine. It is generally lower in mercury than larger tuna species but can still contribute to heavy‑metal exposure if fed in large amounts, may trigger fish allergies in some pets, and should be included as part of a balanced, properly processed diet (raw fish can contain thiaminase and pathogens if not handled correctly).

Mackerel is a fatty fish commonly used in pet foods as a high‑quality animal protein and a rich source of omega‑3 fatty acids (EPA and DHA), often added for flavor, palatability and healthy fats. Its omega‑3s support skin and coat condition, immune and joint health in dogs and cats, but owners should be aware of potential heavy‑metal accumulation, food sensitivities, and higher fat or sodium in some preparations, so choose properly processed, deboned sources from reputable suppliers.

Potato is commonly used in pet foods as a digestible carbohydrate source and functional binder, supplying starch, fiber, and modest amounts of vitamins (B6, C) and potassium—often included as cooked or dehydrated flakes, starch, or protein concentrates. While it provides energy and helps formulate grain‑free recipes, potatoes are not a primary protein for dogs or cats (and are not nutritionally required for obligate‑carnivore cats), can contribute to excess calories or affect blood glucose in diabetic animals, and must be cooked and free of green skins or sprouts to avoid solanine toxicity; allergies are uncommon but possible.

Sunflower oil is used in pet foods as a concentrated fat source to increase energy density, palatability and supply linoleic acid (an essential omega‑6) that helps maintain healthy skin and coat. It is beneficial for dogs and cats but is high in omega‑6 and low in omega‑3—so formulas should balance fatty acids to avoid an inflammatory imbalance; it is calorie‑dense (important for weight control and pancreatitis-prone animals) and may require antioxidants or high‑oleic formulations for better shelf stability.
