Royal Canin Sterilised 37

Before spaying or neutering, a cat's metabolism is adjusted to a diet with an almost constant energy content. The cat eats only as much as it needs to meet its energy requirements. After the procedure, this natural regulatory process is disrupted – the cat begins to eat more than it needs, which can quickly lead to overweight. Just 48 hours after the surgery, the cat's food intake increases by 20%, while its energy requirements simultaneously decrease by about 30%. Urinary stones are more common in sterilized cats, especially if they are overweight, as they typically drink less and therefore produce less urine.
