FreeStyle Cat & Kitten Mackerel, Shrimp & Mussel Stew Wet Cat Food
Verified Jun 9, 2026
This is a high-moisture wet stew for cats and kittens, built around seafood proteins from mackerel, shrimp, and mussel. The formula is complete and balanced for all life stages and includes added taurine plus vitamins and minerals to support overall feline health. Its broth-based texture can be especially useful for boosting hydration in cats that don’t drink much water on their own.
Nutritionally, this is a high-moisture, seafood-based wet food that’s complete and balanced for kittens and adult cats, making it versatile for multi-cat households. The first ingredients are named fish and shellfish, providing animal-based protein, with pumpkin and added prebiotic fiber (inulin) to support gentle digestion. It’s a good option for cats who benefit from extra hydration or prefer a stew-style texture, as long as they tolerate fish and shellfish proteins well.

KibbleLab Review
Strengths
- Named seafood ingredients (mackerel, shrimp, mussel) provide clear, animal-based protein sources at the top of the ingredient list.
- Very high moisture content (82%) helps support hydration, which is particularly helpful for cats prone to low water intake.
- Complete and balanced per AAFCO for all life stages, so it can be used for kittens, adults, and pregnant/nursing cats.
- Includes taurine at a clearly stated level, along with added vitamins, chelated minerals, and prebiotic inulin to support overall health and digestion.
Considerations
- Relatively modest fat level (3% as-fed) compared with many canned foods may not be ideal for very high-energy or underweight cats that need more calorie-dense diets.
- Fish and shellfish (mackerel, shrimp, mussel) are common allergens for some cats, so this wouldn’t be suitable for cats with known fish or seafood sensitivities.
- Contains multiple gums (xanthan and guar) as thickeners; most cats tolerate these well, but a few with very sensitive digestion may do better with simpler textures.

Top 5 Ingredients Explained
01
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.
02
Fish Broth
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.
03
Shrimp
Shrimp is used in pet foods and treats as a lean, palatable animal protein and flavor enhancer that supplies high-quality amino acids and nutrients such as vitamin B12, selenium, phosphorus, small amounts of omega-3s and taurine (important for cats). While nutritious and often well-accepted by dogs and cats, owners should watch for shellfish allergies, high cholesterol and added sodium in processed products, and avoid shells or raw/undercooked shrimp to prevent choking and microbial or contaminant risks—choose cooked, deboned, responsibly sourced shrimp when possible.
04
Mussel
Mussel, especially green‑lipped mussel, is used in pet foods and supplements as a high‑quality animal protein and a natural source of omega‑3 fatty acids plus glucosamine and chondroitin, which can help support joint health and reduce inflammation. It also supplies minerals and B vitamins and can enhance palatability, but owners should be aware of potential shellfish allergies, variability in nutrient content depending on processing and sourcing, and that it should complement a balanced diet—consult your veterinarian if your pet has food sensitivities or is on medication.
05
Pumpkin
Pumpkin is used in pet foods primarily as a fiber-rich carbohydrate and moisture source that can help regulate digestion and firm up loose stools or add bulk for softer stools, and it provides beta-carotene (vitamin A precursor) plus small amounts of vitamins and minerals for dogs and cats. It is safe and beneficial when plain cooked or canned (not spiced or sweetened pie filling), should be fed in moderation as a supplement rather than a primary food, and introduced gradually since large amounts can cause gastrointestinal upset or interfere with absorption of some medications.
