Is the Royal Canin Sterilised formula suitable for all cat life stages or only for neutered adult cats?

The Sterilised formula is intended exclusively for neutered cats between one and seven years old; it is not recommended for kittens, senior cats beyond seven years, or unneutered cats because its nutrient balance is tailored to the metabolic needs of adult sterilized felines.

What is the primary protein source in this food, and how does the inclusion of wheat and corn gluten affect feline digestion?

The main protein comes from dehydrated poultry protein, supplemented by a vegetable protein isolate; wheat and corn gluten introduce plant‑based carbohydrates and gluten, which can be harder for some cats to digest and may trigger sensitivities, although they also provide energy and texture to the kibble.

Does this cat food contain common allergens such as gluten, and what precautions should owners of sensitive cats take?

Yes, the product lists wheat and corn gluten, both recognized allergens for cats; owners of pets with known grain or gluten sensitivities should consider a grain‑free alternative or consult a veterinarian before feeding this diet.
