Specific needs

Your sterilised/neutered1 cat may be at risk

Many responsible pet owners neuter their cats to avoid unwanted pregnancies and help to control the overall pet population, amongst other behavioural and health requirements.

However, after neutering cats are at increased risk of two specific health conditions. The good news is that specific nutrition for sterilised cats provides a solution to help reduce these risks

Discover the right Science Plan cat food for your sterilised/neutered cat:


Over 3 times higher risk of becoming overweight2

  • Metabolism slows down, making cats
    more prone to weight gain3
  • Appetite increases by up to 25% whilst
    energy expenditure decreases by an
    average of 30%4,5
  • Overweight cats are at a higher risk of
    health problems
    such as diabetes
    and lameness6

Sterilised cats1 are over 3 times more likely to develop bladder stones7

  • Overweight cats are less active and may
    drink and urinate less frequently
  • Urine becomes more concentrated and
    urinary stones are likely to form
  • Incorrect urinary pH and excess
    minerals in the food may cause stones
    to form

Urinary stones may form because your cat becomes overweight, moves around less and drinks and urinates less frequently
