## Long description

Mastery Wellness CORE 10831 4 kg — Adult, Salmon & Tuna, Grain-free is a dry cat food formulated for adult cats of all breeds. This grain-free recipe uses salmon and tuna as primary animal protein sources to supply essential amino acids and fatty acids for maintenance of muscle condition, skin and coat. The formula is designed for everyday feeding to help support general wellbeing with a nutrient-dense profile that balances high-quality protein, fiber and supplemental nutrients.
Advantages
The fish-based formula avoids poultry proteins and provides a concentrated source of omega-rich ingredients from salmon, salmon oil and tuna, supporting healthy skin and a shiny coat. The recipe includes linseed as a source of omega-3, and added salmon oil supplies DHA. Prebiotic fibres and probiotics contribute to digestibility and intestinal health while higher fibre content helps reduce hairball formation. Controlled sodium levels and joint-supporting ingredients are included to support overall adult cat health.
Suitable for
 Adult cats of all breeds requiring a grain-free diet
 Cats with sensitivities to poultry proteins
 Animals needing support for skin and coat condition
 Cats prone to hairballs or mild digestive sensitivity

How to use
Introduce Mastery Wellness CORE gradually over 7–10 days by mixing increasing amounts of the new food with the previous diet until fully transitioned. Feed according to your cat’s current weight, age, activity level and body condition; consult the feeding guide on the packaging for daily portions. Provide fresh water at all times. Monitor body condition regularly and adjust portions to maintain an ideal weight. Store the dry food in a cool, dry place and reseal the bag after each use to preserve freshness.
Usage recommendations
For adult maintenance feeding, combine measured daily portions with regular monitoring of weight and coat condition. If your cat has specific medical issues or special dietary needs, consult a veterinarian before changing to this fish-based, grain-free diet. When feeding to multiple cats, measure portions individually to avoid overfeeding.
