A neutered cat's calorie needs drop the moment the operation is done, and a food branded "Sterilised" is really just a lower-calorie recipe wearing a more specific name.

There are two recipes in this box: chicken and beef, both meat and animal derivatives at 4% each, alongside vegetable protein extracts, fish and fish derivatives and minerals. Moisture comes out at 78%, protein at 13%, fat at 3.3%, crude ash at 2.0% and crude fibre at 0.4%. Purina's feeding guide for an average 4kg cat is 2 1/2 pouches a day, split across at least two meals, and taurine is added at 560mg per kg.

No fibre bump for weight control. "Sterilised" foods are usually built around lower fat and a bit more fibre to help a less active cat feel full. This one's fat figure (3.3%) is on the low side, but the fibre figure (0.4%) is not unusually high, so do not assume it does the whole job of managing a neutered cat's weight on its own.

Who it's for: owners of a neutered or spayed cat wanting a lower-fat wet food, bought in bulk rather than by the single pouch.
