MedalSeries Cat & Kitten Mackerel, Shrimp & Mussel Stew Wet Food
Verified Jun 5, 2026
A high-moisture wet food for kittens and adult cats featuring mackerel as the main protein, with shrimp and mussel adding extra animal protein variety. The stew-style formula is designed to support hydration while providing complete and balanced nutrition for all life stages. Pumpkin, added oils, and a full vitamin–mineral supplement help round out the diet nutritionally.
This is a high-quality, fish-based wet food that provides complete and balanced nutrition for cats at all life stages, including kittens. It offers multiple animal protein sources and a very high moisture content, which is especially helpful for urinary tract health and overall hydration in cats. It should suit most healthy cats who do well on fish, though it may not be ideal as the sole long‑term diet for cats with known fish allergies or very high calorie needs.

At a Glance
KibbleLab Review
Strengths
- Mackerel as the first ingredient, with shrimp and mussel providing additional named animal protein sources.
- High moisture (82%) supports hydration, which is particularly beneficial for cats that don’t drink much water on their own.
- Formulated to meet AAFCO nutrient profiles for all life stages, so it’s appropriate for kittens, adults, and pregnant/nursing cats when fed as directed.
- Includes taurine at an appropriate level for cats, along with a full complement of vitamins and chelated minerals for good nutrient availability.
Considerations
- Fish (mackerel, shrimp, mussel) are common allergens for some cats, so this wouldn’t be suitable for cats with known fish sensitivities.
- The minimum fat content (3% as-fed) is on the leaner side for a cat food, which may not provide enough calories for very active cats or some growing kittens unless portions are increased accordingly.
- Menadione sodium bisulfite complex (a synthetic vitamin K source) is included; it’s allowed and commonly used in pet foods but is somewhat controversial among some nutrition professionals.

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.
