Sterilised cat food
Lower-fat foods with L-carnitine and balanced minerals, tackling the weight gain and urinary risk that follow neutering.
After neutering, a cat's energy needs drop by around 20–30%, while appetite often increases. Carrying on with the same food in the same amount leads to weight gain within a few months, and excess weight is a major risk factor for diabetes, joint problems and urinary disorders.
How sterilised cat food differs
- Less fat and fewer calories, but a higher protein level to protect muscle mass
- L-carnitine to support fat metabolism
- Fibre to help your cat feel full
- A controlled mineral profile, with managed magnesium and phosphorus, to balance urine pH
There is no need to change food immediately after surgery; focus on recovery for the first one or two weeks, then switch to sterilised cat food over a gradual 7–10 day transition. If your kitten was neutered before 12 months, either continue kitten food with controlled portions or choose a recipe made for sterilised kittens.
Calculate the portion from your cat's ideal weight and weigh it monthly. You should be able to feel the ribs easily under a thin layer of fat and see a waistline from above. Adding one wet meal a day raises water intake and gives extra support to urinary health. Encouraging movement with play sessions and scratching posts matters just as much as the food itself.
Common questions about Sterilised cat food
When should I switch to sterilised cat food?
Once your cat has fully recovered, one or two weeks after surgery, you can switch gradually. For kittens, wait until 12 months or choose a sterilised kitten recipe.
Will sterilised cat food make my cat lose weight?
Its main aim is to prevent weight gain. If your cat is already overweight, plan a weight-control (light) programme with your vet.
Can an unneutered cat eat this food?
It is not harmful for a healthy adult indoor cat, but active, unneutered cats are usually better served by standard adult food in terms of energy.
