How much does it cost to neuter a male cat in the UK?
Castrating a male cat is a quicker, simpler operation than spaying a female, and the price usually reflects that. It is one of the cheaper routine procedures at most practices, but the figure still varies more than you might think. The real prices below are drawn from actual invoices, and this guide explains what sits behind the number.
The quick version
- The real median and range for castrating a male cat are shown below.
- It is generally cheaper than a female spay because the surgery is shorter and less invasive.
- Ownership still matters. Corporate practices averaged 18.3% more than independents in the 2026 CMA study.
- A low headline price may leave out pain relief or the post-op check, so ask what is included.
What people actually paid
Why the price varies so much
Even for a straightforward procedure, prices move around. Practice overheads and location set the baseline, and corporate ownership tends to push figures higher than at independents. What the quote bundles in matters too, since some practices include take-home pain relief and a check-up while others charge for them separately. Cats with an undescended testicle need a more involved operation that costs more, so mention it if you know one has not dropped. General price pressure across the sector has been strong, with vet fees up 63% from 2016 to 2023, so quotes have crept up year on year.
How to pay less
- Phone around and ask for the total including any pain relief and the follow-up appointment.
- Check an independent practice as well as the nearest corporate branch before booking.
- See whether a charity or council low-cost neutering scheme covers you, as many do for male cats.
- Compare the price lists practices must publish from September 2026 rather than guessing from old figures online.
Common questions
Why is neutering a male cat cheaper than spaying a female?
Castration is a shorter operation that does not involve opening the abdomen, so it needs less anaesthetic and theatre time. That lower workload is reflected in the lower price at most practices.
At what age should a male cat be neutered?
Many vets neuter from around four months, and charities often recommend doing it before a cat starts roaming and spraying. Ask your own practice, as the cost is usually the same regardless of age within the normal range.
What if one testicle has not dropped?
An undescended (cryptorchid) testicle needs to be found and removed surgically, which is a bigger operation than a routine castration and costs more. Tell the practice in advance so the quote is accurate.
