Whiskas
1+ Adult with Tuna
Summary
Whiskas 1+ Adult with Tuna is formulated around cereals as the primary energy source to support active adult cats aged one year and older.
Meat and animal derivatives and fish and fish derivatives—including 4% tuna in the brown kibbles—provide high-quality protein and essential amino acids to maintain lean muscle and organ function.
Adding taurine at 1300 mg/kg helps ensure cardiovascular health and clear vision by supporting retinal function.
A balanced mineral profile, featuring calcium, phosphorus, and controlled magnesium, supports strong bones and healthy lower urinary tract function.
A blend of oils and fats supplies essential fatty acids, while fish derivatives contribute omega-3s, supporting a healthy skin barrier and a glossy coat.
Yeasts contribute B vitamins and antioxidants, bolstering immune function and cell metabolism.
Vegetable protein extracts enhance overall amino acid balance and digestibility without relying solely on animal sources.
Natural fibers from vegetable derivatives, such as carrots and peas, aid digestion and help prevent hairball formation.
Vitamin A supports vision clarity, and zinc promotes healthy skin and coat condition.
Manufactured with 100% renewable energy and free from artificial colors and flavorings, this formula reflects a commitment to sustainability and natural taste appeal.
Pros:
- High-Quality Protein: Meat, animal derivatives, and fish provide essential amino acids for muscle maintenance and overall health.
- Essential Amino Acid Taurine: Added taurine at 1300 mg/kg supports heart function and clear vision.
- Balanced Minerals: Calcium, phosphorus, and controlled magnesium levels promote bone strength and lower urinary tract health.
- Omega Fatty Acids: Oils, fats, and fish derivatives supply omega-3 and omega-6 for skin hydration and a glossy coat.
- Natural Fiber Sources: Vegetable derivatives, carrots, and peas support healthy digestion and hairball control.
Cons:
- High Carbohydrate Content: With 36.9% carbohydrates, the formula relies heavily on cereals and vegetable starches, which may be higher than ideal for strict carnivores.
- Added Sugars: Inclusion of various sugars can contribute to unnecessary calories and potential weight gain in less active cats.
- Moderate Fat Level: At 12% crude fat, very active cats may require additional fat sources to meet their higher energy demands.
- Low Fiber: The crude fiber content at 2.2% may be insufficient for some cats that require extra fiber to manage hairballs effectively.
- Limited Tuna Inclusion: Only 4% tuna in the brown kibbles translates to a modest direct fish content relative to the overall formula.

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.
