our cat’s metabolism before sterilisation is able to cope with a constant supply of energy and it would only eat only as much as is necessary to meet its energy demands. After the sterilisation however, your cat’s body loses the ability to regulate and it frequently eats more than it needs, which can lead to weight gain. Older cats may also have age related issues such as less activity or renal problems.
As soon as 48 hours after sterilisation has taken place, your cat’s ingestion can rise by 20% while energy demand may decline by 30%. A reduction in carbohydrates can lead to a rise in blood sugar which prevents your cat from feeling hungry again too quickly. Bladder stones can occur in sterilised cats, especially if they are overweight, because they drink less and produce less urine. A balanced mineral content keeps the pH value of the urine low and helps to keep the urinary tract healthy. An increased protein content can boost and preserve muscle mass.

Royal Canin Sterilised 37 cat food was specially developed for sterilised cats with a tendency to weight gain:

  • The aging process: is made easier by ingredients in this recipe and your cat is able to grow old gracefully and with fewer problems
  • Controlled energy supply: through reduced fat contents (12%)
  • Fewer carbohydrates: e.g. no starch which stimulates hunger pangs
  • L-Carnitine: (100 mg/ kg) helps to mobilise fat reserves
  • Promotes healthy urinary tract: through balanced pH-levels in the urine (pH 6-6,5) and a balanced phosphorus content
  • Boosts and preserves muscles: through high protein contents (36%
