Summary

Still Joy Tuna and Salmon is a complete dry food formulated for adult cats, designed to support daily nutritional needs with a focus on palatability and digestibility.
The primary protein source is fish, specifically tuna and salmon, which are included in the form of fish and fish by-products, providing high-quality protein with a favorable amino acid profile to support muscle maintenance and overall vitality.
With a crude protein content of 31% and fat at 11%, the formula provides a balanced macronutrient profile suitable for moderately active adult cats, whether they are indoor or outdoor cats.
The inclusion of taurine at 400 mg/kg supports essential feline functions such as heart health and vision, which cats cannot maintain without dietary intake.
Fructooligosaccharides (FOS), derived from chicory inulin, contribute to digestive health by promoting beneficial gut bacteria and enhancing nutrient absorption.
Vitamin A, biotin, and zinc are included to support skin elasticity and promote a shiny, healthy coat, which is especially important for cats prone to skin dryness or dull fur.
Calcium (1.4%) and phosphorus (0.9%) are present in a ratio that supports bone and dental health, which is essential for adult maintenance.
The metabolizable energy of 3535 kcal/kg provides sufficient caloric density to meet the energy needs of adult cats without promoting excessive weight gain.
The addition of methionine (0.43%) and lysine (1.4%) enhances the amino acid profile, supporting immune function and lean muscle development.
Choline chloride (2500 mg/kg) contributes to liver function and fat metabolism, helping maintain healthy organ function in adult cats.

Pros
Expand All
1

High-quality fish proteins

Tuna and salmon offer digestible protein with essential amino acids for muscle maintenance and overall health.
2

Digestive support with FOS

Chicory-derived fructooligosaccharides promote gut health and improve nutrient absorption.
3

Skin and coat health

Vitamin A, biotin, and zinc work together to support a glossy coat and resilient skin barrier.
4

Balanced calcium-phosphorus ratio

Supports bone strength and dental health in adult cats.
5

Essential amino acid supplementation

Added lysine and methionine enhance protein quality and support immune and muscle function.
Cons
Expand All
1

Low fish inclusion rate

Tuna and salmon make up only 8% of the formula and are limited to a portion of the kibble, reducing the overall fish protein contribution.
2

Use of unspecified cereals

The presence of generic cereals as the first ingredient may indicate a high carbohydrate load and lower protein density.
3

High carbohydrate content

At 37%, the carbohydrate level is relatively high for obligate carnivores and may not suit cats requiring lower-carb diets.
4

Use of meat and fish by-products

These ingredients can vary in quality and may be less digestible than whole meat sources.
5

Moderate ash content

At 8%, the ash level may be a concern for cats with urinary or kidney sensitivities.

Notes

Information about antioxidants and preservatives is missing or insufficient. Since I didn’t want to remove points due to this missing info without any proof, I evaluated this food assuming the natural preservatives were used. But note that this is just an assumption.
Ingredients in this food are listed as categories rather than specific named products. This EU permitted method doesn’t allow me a proper evaluation of the food since I usually don’t have any indication of the real quality of ingredients in each listed category. Therefore I evaluate each such category as the corresponding ingredient of the worst quality: cereals = corn, meat and meat derivatives = partial by-product + unknown source of the meat, oils and fats = unknown source of the fat.

How the score is calculated?

The actual calculation of the score is based on sophisticated and advanced algorithm that takes into account multiple parameters.

To simplify the explanation, the calculation is based on three main criteria:

(1) Amount of protein (more is better)

(2) Amount of carbohydrates (less is better)

(3) Quality and source of ingredients.

Based on that 3 main criteria, 9 score calculation rules are used to compare the different foods.

One major assumption is that the closer an ingredient is to the top of the ingredient list, the greater its relative weight and contribution to the food.

In general, cat food is composed of protein, fats, carbohydrates, fibers, vitamins, and minerals.

Protein is the most important component in a cat's diet, and cats primarily get their protein from animal meat.

Fat is a primary source of energy and essential fatty acids.

Carbohydrates are controversial in a cat's diet, as cats are obligate carnivores and typically consume very few carbohydrates.

Fibers play an important role in digestion and food absorption, and vitamins and minerals are essential for different organism functions.

Dry matter values are used to compare the amount of nutrients in different cat foods. This means that moisture is excluded from the equation to provide a more accurate comparison.

Putting all of these and more into a formula results in a product score.

The maximum score a cat food can receive is 100. Points are added or removed based on the score calculation rules.
