Royal Canin Feline Health Nutrition Sterilised Jelly (Wet Food - 85G Pouches) When cats are sterilised, their nutritional requirements change compared to cats that haven't been spayed or neutered. As a result of sterilisation, your cat will have lower energy needs and could be less active than before. That's why ROYAL CANIN Sterilised in Jelly is specially formulated with the nutritional needs of your neutered adult cat and its lower levels of activity in mind. With a controlled energy content and a moderate level of fat, ROYAL CANIN Sterilised in Jelly helps to support and maintain a healthy weight; particularly when served in accurate daily rations.
