True Instinct Grain Free Ocean Whitefish Dry Cat Food

Verified Jun 30, 2026

Cat · Dry Adult All Breed Sizes

This is a high‑protein, grain‑free dry food for adult cats, using ocean whitefish and chicken meal as the main animal protein sources. Pea starch, cassava, and soy ingredients provide additional protein and carbohydrates, while added taurine, vitamins, and minerals help support overall health. It’s designed for normally active adult cats who do well on a grain‑free, kibble diet.

KibbleLab Score
8.0 out of 10

Overall, this is a well‑formulated adult dry cat food with a strong protein content and ocean whitefish listed first, supported by chicken meal, egg product, and several plant and soy proteins. It is fully complete and balanced for adult maintenance and should suit many healthy adult cats that tolerate fish, chicken, and soy. The grain‑free design relies on peas, cassava, and soy rather than grains, which works fine for most cats but isn’t automatically healthier than grain‑containing formulas.

Nutritional Perspective

KibbleLab Review

Strengths

  • High protein level for a dry cat food (35% minimum) with multiple animal protein sources, including ocean whitefish and chicken meal.
  • Complete and balanced nutrition for adult cats, with added taurine and a full vitamin and mineral premix.
  • Relatively moderate fiber (2% max) and fat (14% min), which can work well for many average‑activity adult cats.
  • No artificial flavors or preservatives, and fat is preserved with mixed tocopherols, a form of vitamin E.

Considerations

  • Contains fish, chicken, egg, soy, and beef fat, all of which can be triggers for cats with food allergies or sensitivities.
  • Grain‑free but relies on peas, cassava, and soy ingredients for part of its protein and carbohydrate content; this isn’t inherently better than well‑made grain‑inclusive diets.
  • Uses multiple concentrated plant and soy proteins (soy protein isolate/concentrate, pea protein), so not all of the labeled protein comes from animal sources, which some cats with higher protein needs might not do as well on.

Top 5 Ingredients Explained

01
Ocean White Fish
Ocean white fish is a lean, highly digestible animal protein commonly used in dog and cat foods to provide essential amino acids, improve palatability, and contribute some omega‑3 fatty acids and B vitamins. It can be a good low‑fat option for weight- or renal‑management diets, but may be an allergen for some pets and can carry environmental contaminants (e.g., mercury) depending on species and sourcing, so quality and source transparency are important.
02
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.
03
Pea Starch
Pea starch is used in pet foods primarily as a carbohydrate binder, thickener and texture agent to help form kibble and provide readily digestible energy, rather than as a protein or fiber source. It is a gluten‑free, highly digestible starch that can increase calorie density and glycemic load (important for overweight or diabetic pets) and, like other pea/legume ingredients used in high amounts in some grain‑free diets, should be part of a balanced formulation chosen with veterinary guidance for pets with special health concerns.
04
Cassava Root Flour
Cassava root flour is used in pet foods primarily as a gluten‑free carbohydrate and thickening agent, providing readily digestible energy and functioning as a binder in dry and canned formulas. It is low in protein and fat and provides few vitamins or minerals, so it is not a complete nutrient source; commercially processed cassava is generally safe but raw cassava contains cyanogenic compounds and its high glycemic index may be a consideration for pets with diabetes or weight management needs.
05
Soy Protein Isolate
Soy protein isolate is a concentrated plant-based protein derived from defatted soy and is commonly used in dry and canned pet foods as a protein source, binder and texturizer to boost crude protein and improve kibble structure. It provides substantial protein and some essential amino acids but is generally less bioavailable than animal proteins and low in taurine (a concern for obligate carnivores like cats); some pets may be allergic to soy and soy contains phytoestrogens, though most anti-nutritional factors are reduced during processing, so consult your veterinarian for diets relying heavily on plant proteins.
