Cat neutering is significantly cheaper than dog neutering and is one of the most straightforward veterinary surgeries. As a responsible cat owner, getting your cat neutered helps control the UK's stray cat population and can prevent health issues later in life.

Average Costs in the UK

  • Male cat castration: £50 to £100 (average around £70)
  • Female cat spaying: £100 to £200 (average around £150)

Male castration is a simpler, shorter procedure, which is why it costs less. Female spaying requires abdominal surgery and a longer recovery period.

Why Prices Vary So Much

The CMA's investigation into the UK veterinary market found significant price variation between practices, even in the same postcode area. Key factors include:

  • Location: London practices can charge 20–30% more than rural areas
  • Practice type: Corporate-owned practices charge an average of 17% more than independents (CMA, 2025)
  • Additional costs: Some practices include pain relief and a post-op check; others charge extra
  • Keyhole (laparoscopic) spaying: Available at some practices for £250–£400 — less invasive with faster recovery but significantly more expensive

What Should Be Included

A neutering quote should cover:

  • Pre-operative check
  • General anaesthetic
  • The surgery itself
  • Post-operative pain relief (typically a single injection plus take-home tablets)
  • Follow-up check at 3 and 10 days post-surgery

If your quote seems very low, check whether pain relief and the post-op visit are included. Some budget pricing excludes these essentials.

Free or Subsidised Neutering

Several UK charities offer free or low-cost cat neutering:

  • Cats Protection: Runs the largest cat neutering programme in the UK, offering vouchers worth up to £50 for eligible owners
  • PDSA: Free treatment for pets of owners receiving qualifying benefits
  • RSPCA: Subsidised neutering at RSPCA animal hospitals and partner practices
  • Blue Cross: Free neutering at Blue Cross animal hospitals for eligible owners

Visit each charity's website to check eligibility, which is usually based on receiving means-tested benefits and living in their catchment area.

Best Age to Neuter a Cat

Cats Protection and the British Veterinary Association both recommend neutering at four months of age. Cats can become pregnant from as young as four months, so early neutering is important to prevent unplanned litters.

Recovery Time

Male cats typically recover within 24–48 hours. Female cats need 7–10 days to heal from the surgical wound. Your vet will provide a buster collar or medical body suit to prevent licking at the stitches.
