Some cats need a short ingredient list. Not because short is inherently better, but because when you're dealing with a cat that reacts to land-animal proteins — chicken, beef, lamb, venison — having a complete wet food built entirely around a single fish source, with nothing terrestrial in the mix, removes the guesswork from elimination feeding.
ZIWI Peak Mackerel is the simplest recipe in the range by design: whole NZ Blue Mackerel caught from the cold, remote waters around New Zealand, combined with NZ Green Mussel, dried kelp, and the vitamins and minerals required for complete nutrition. That's essentially it. No organ cuts from land animals, no secondary proteins from another species. Just mackerel, the way a cat's digestive system deals with it without any additional variables in the equation.
The numbers are worth noting. At 12% crude protein and 3% fat, this is the highest protein and leanest wet recipe ZIWI makes — useful for indoor cats, weight-managed cats, or any situation where protein delivery matters more than calorie density. Natural EPA and DHA from whole mackerel support skin, coat, and inflammatory response without supplementation. DL-Methionine supports urinary pH. Dried kelp provides iodine for thyroid function. NZ Green Mussel adds natural chondroitin sulphate for joint health.
Single-Protein Mackerel — No Land-Animal Ingredients The only ZIWI wet cat recipe built around fish alone. Useful as a true elimination diet option for cats reacting to chicken, beef, lamb, venison, or any combination of land-animal proteins.
12% Protein, 3% Fat — Leanest & Highest Protein in the ZIWI Wet Range Whole mackerel delivers strong protein numbers at low fat — suited to indoor cats, less active cats, or weight-management feeding where protein quality matters more than calorie density.
Sustainably Caught NZ Blue Mackerel — Natural Omega-3 Wild-caught from New Zealand's government-managed fisheries. EPA and DHA arrive from the whole fish, not from isolated oil supplementation, alongside naturally occurring fat-soluble vitamins.
NZ Green Mussel + Dried Kelp Whole-food source of chondroitin sulphate for joint support. Dried kelp contributes natural iodine for thyroid health — particularly relevant in single-protein diets that may otherwise lack mineral diversity.
DL-Methionine — Urinary pH Support Supports healthy urinary acidification — important for cats on high-fish diets where alkaline urine can become a concern over time.
