Royal Canin Sterilised cat food is a complete and balanced cat food for sterilised adult cats (from 1 to 7 years) tending to gain weight. After neutering, the energy requirement of a feline decreases. The decline in the energy demand may lead to excess weight gain. To reduce the risk of weight gain, the amount of fats in the wholesome diet has been reduced. L-carnitine is added to promote the metabolism of fat. A high level of protein works to maintain strong and lean muscles. Royal Canin Sterilised cat food contains good quality mineral content which has been adapted adequately to support the health of the urinary tract.
