Grain Free Wholesome Tuna in Gravy Flaked Canned Cat Food
Verified May 31, 2026
A grain-free canned food for cats of all life stages, this recipe uses tuna as the primary protein in a flaked texture with gravy. It’s a relatively light formula with modest fat, relying on tapioca for structure and sunflower oil for added fat and essential fatty acids. The diet is formulated to be complete and balanced for kittens through adult cats, including added taurine and a full vitamin and mineral mix.
This is a straightforward, tuna-based wet food that’s complete and balanced for all life stages and formulated to AAFCO standards. Protein is reasonable for a canned food, but fat is quite low, making it more of a lean option than a rich, calorie-dense diet. It could work well for cats that do better on a lighter wet food, but may not be ideal as the sole diet for very active, growing, or underweight cats without careful portion management.

KibbleLab Review
Strengths
- Tuna as the first ingredient provides an animal-based protein source that most cats find palatable.
- AAFCO-complete and balanced for all life stages, so it can be used for kittens and adults if fed in appropriate amounts.
- High moisture (up to 85%) helps support hydration, which is especially helpful for cats that don’t drink much water.
- Includes added taurine and a full complement of vitamins and minerals to support essential feline nutrient needs.
Considerations
- Crude fat is quite low for a wet cat food (minimum 1.5%), so some cats may need larger portions or an additional food to meet their energy needs.
- Tuna-heavy diets can contribute to a narrow protein rotation; many cats do better long term with some variety in protein sources.
- Fish-based foods can be problematic for cats with fish allergies or sensitivities, so it’s not suitable for those individuals.
- Relatively low ash is a positive, but as with all fish-based diets, it’s best to discuss with your vet if your cat has a history of urinary tract issues.

Top 5 Ingredients Explained
01
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.
02
Tuna Broth
Tuna broth is used in pet foods and toppers mainly as a flavor enhancer and moisture source to improve palatability and encourage hydration; it may contribute small amounts of fish-derived protein and omega‑3s but is not a significant standalone protein source. While it can make meals more appealing, pet parents should watch for added salt or preservatives, potential fish allergies, and contaminants such as mercury or histamine, and remember tuna broth does not provide a complete, balanced nutrient profile (including taurine for cats).
03
Natural Flavor
Natural flavor is used primarily as a palatability enhancer in pet foods to improve taste and aroma and is not intended to provide significant nutrients, typically coming from concentrated extracts of meat, poultry, plant, or fermentation sources. While it can increase acceptance in picky dogs and cats, manufacturers are not required to disclose specific sources so pets with known sensitivities or allergies may react, and presence of natural flavor should not be taken as a guarantee of overall product quality.
04
Tapioca
Tapioca is a processed starch from the cassava root commonly used in pet foods and treats as a gluten-free carbohydrate, binder and thickening agent, providing easily digestible calories but very little protein, fat, vitamins or minerals. While useful in hypoallergenic or grain-free formulations, it has limited nutritional value and a high glycemic index, so it should be used in moderation—especially for overweight or diabetic dogs and cats—and only in properly processed form to avoid cassava-related toxins.
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.
