Quick answer

Calibra Cat Premium Sterilised Salmon is a complete dry food for adult neutered cats, made without wheat, soy, GMOs, artificial colours, or antioxidants. It suits owners who want an affordable, salmon-based daily diet with controlled portions for weight management. Feed by weight and body condition, transition over 7–10 days, and measure portions rather than free-feeding.

Why sterilised cats need a different feeding approach

After neutering, a cat's energy needs often drop by around 20–30%, while appetite may stay the same or increase. That mismatch is why many neutered cats gain weight on the same food and portion that kept them lean before surgery. A sterilised-specific recipe like Calibra Cat Premium Sterilised Salmon is formulated with this lower energy requirement in mind, but the food alone does not control weight—your measuring cup does.

The practical takeaway: treat the feeding table on the pack as a starting point, then adjust every two weeks based on body condition. You should be able to feel your cat's ribs easily without seeing them, and see a visible waist from above.

How to transition from another food without stomach upset

Sudden diet changes are a common cause of vomiting and loose stools in cats. Mix the new food with the old one over 7–10 days: start with 25% new food for three days, then 50% for three days, then 75% for three days, and finally 100%. If your cat has a sensitive stomach, extend each stage to five days.

During the transition, keep the total daily amount the same as the old food's recommendation, then switch to the Calibra feeding table once your cat is fully on the new recipe. If you also feed wet food, such as Calibra Cat Life Pouch Adult Veal, reduce the dry portion by roughly 10–15 grams for every 85g pouch to avoid overfeeding.

Portion control and weight monitoring

Weigh your cat monthly on the same scale, and record the number. A 5% weight gain (about 250g for a 5kg cat) is your cue to reduce the daily portion by 10%. Do not cut food drastically; a slow, steady reduction is safer and more sustainable. Use a kitchen scale for dry food—measuring cups vary widely.

If your cat begs between meals, split the daily ration into three or four small meals rather than increasing the total. Puzzle feeders and slow-feed bowls can stretch a small portion over a longer period.

When salmon-based sterilised food is not the right choice

If your cat has been diagnosed with a food allergy or intolerance, a novel-protein veterinary diet is a better fit. Calibra VD Cat Hypoallergenic Duck uses duck as the sole animal protein source and is grain-free, which is relevant for cats with skin problems such as dermatosis or excessive hair loss. That is a therapeutic decision, not a preference—ask your vet before switching.

Similarly, if your cat has kidney or heart disease, a renal or cardiac support diet is needed. Calibra VD Dog Renal & Cardiac is a dog product, so it is not suitable for cats, but it illustrates the principle: prescription diets target specific organ support, while Calibra Cat Premium Sterilised Salmon is a maintenance food for healthy neutered adults.

Decision rules for feeding Calibra Sterilised Salmon

  • If your cat is a healthy neutered adult: Start with the pack's feeding table for your cat's ideal weight, not current weight if overweight. Weigh the food and adjust every two weeks based on body condition. Measured portions beat free-feeding for sterilised cats.
  • If your cat has a sensitive stomach or is a picky eater: Mix in a small amount of Calibra Cat Life Pouch Adult Veal (up to 20% of the daily ration) to improve acceptance, and reduce the dry food accordingly. Wet toppers can help, but they count toward daily calories.
  • If your cat has skin or digestive issues suspected to be food-related: Do not switch to a sterilised maintenance diet as a treatment. Ask your vet about a hypoallergenic diet such as Calibra VD Cat Hypoallergenic Duck. Therapeutic diets require veterinary guidance.
  • If your cat is not losing weight on the recommended portion: Reduce the daily amount by 10%, increase play sessions to two 10-minute active games per day, and recheck weight in two weeks. Do not drop below the minimum for your cat's ideal weight without vet advice. Slow adjustments and activity are safer than crash dieting.
