Mack & Jack Mackerel & Grilled Skipjack In Gravy Wet Cat Food
Verified Jun 17, 2026
This is a fish-based wet cat food featuring tuna, mackerel, and skipjack in a gravy-style formula, designed for adult cats. It offers moderate protein with very low fat and high moisture to help support hydration. The recipe is fortified with essential vitamins, minerals, and taurine to meet the needs of obligate carnivores when fed as a complete diet.
This is a high-moisture, fish-based canned food that can work well for adult cats who enjoy seafood and may benefit from a lower-fat diet. Protein comes from named fish sources, and the formula has relatively low ash, calcium, phosphorus, and magnesium levels, which many indoor and urinary-prone cats do well on. It’s best suited as a primary or rotational diet for healthy adult cats that tolerate fish proteins without issue.

KibbleLab Review
Strengths
- Named fish ingredients (tuna, mackerel, skipjack) provide clearly identified animal protein sources appropriate for cats as obligate carnivores.
- Very high moisture and relatively low mineral levels (calcium, phosphorus, magnesium) can be helpful for supporting good urine dilution and overall hydration.
- Low fat content may be useful for cats that need a leaner diet under veterinary guidance.
- Includes taurine and a full vitamin–mineral premix to help support complete and balanced nutrition.
Considerations
- Fish (tuna, mackerel, skipjack) are common allergens for some cats, so this formula is not ideal for cats with known fish sensitivities.
- Very low fat may not be ideal for all cats long term, especially very active or underweight cats who may need more calories from fat.
- The use of multiple gums (locust bean gum, guar gum) is generally safe, but a few very sensitive cats can experience soft stools with certain gums.

Top 5 Ingredients Explained
01
Water
Water is an essential nutrient and the primary solvent and moisture component in pet foods, especially wet and canned diets, and is also used in processing and to adjust texture and palatability. It is vital for digestion, nutrient transport, temperature regulation and waste removal in dogs and cats; pets must have constant access to clean water as dehydration can quickly lead to serious health issues and requirements increase with activity, heat, or illness, while moisture in wet food can help meet part of their daily needs.
02
Tuna
Tuna is commonly used in pet foods as a highly palatable animal protein and flavor enhancer, providing readily digestible protein and omega‑3 fatty acids (EPA/DHA) along with B vitamins for both dogs and cats. While nutritionally beneficial, tuna can be high in mercury or sodium (especially canned), and feeding it exclusively or frequently may cause nutrient imbalances (including risks for thiamine or taurine issues in cats), so it should be offered in moderation as part of a complete, balanced diet.
03
Mackerel
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.
04
Skipjack
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).
05
Sunflower Oil
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.
