Prior to sterilisation, the metabolism of your cat self-adjusts to variable energy requirements. Your cat eats only as much as to cover his or her energy demands. After the sterilisation however, your cat loses this regulation capability, and eats more than necessary. This can lead to weight gain and health problems.
Within 48 hours of the sterilisation taking place, your cat’s ingestion rises with 20% while his energy demand declines by 30%.
Bladder stones are frequent problems for sterilized cats, since they drink less, and especially if they are overweight.
Royal Canin Sterilised 37 cat food was specially developed for sterilised cats with weight gain problems:
Balanced energy supply: through reduced fat contents (12%)
Less carbohydrates: e.g. no starch (stimulates hunger)
L-Carnitine: (100 mg/ kg) helps in the consumption and disposal of fats
Promotes healthy urinary tract: through balanced pH-levels in the urine (pH 6-6,5)
Boosts and preserves muscles: through high protein contents (37%)
