Why neuter a cat

  • Females: an unspayed cat comes into heat several times a year, calling, spraying and trying to get out. In the long run she risks pyometra (a life-threatening womb infection) and mammary tumours. Spaying before six months cuts the mammary tumour risk by more than 90%.
  • Males: less spraying, fighting and roaming, and less chance of catching FIV through bite wounds.
  • Multi-cat homes: no accidental litters.

The best age

We usually recommend 4 to 6 months, before the first heat. Adult cats and cats that have already had kittens can be neutered too, provided the examination and blood tests are normal. A female in heat is usually booked for after the heat has passed, to reduce bleeding risk.

Before the operation

  1. We arrange a pre-operative check when you book; cats over six or with a medical history are advised to have blood tests.
  2. No food for 8 to 12 hours before surgery; water is fine.
  3. Bring your cat in a secure carrier, not a fabric bag.
  4. No breakfast on the morning of surgery.

On the day

Spaying removes the ovaries and uterus (or the ovaries only) through a small abdominal incision; castration removes the testicles and needs no stitches. Both are done under general anaesthesia with heart rate, oxygen and blood pressure monitored throughout. Most cats go home the same day. Males are lively that evening; females are usually eating normally within one to two days.

Aftercare

  • Recovery collar on for 7 to 10 days so the wound is not licked.
  • No jumping or rough play for about 10 days for females.
  • Keep the wound dry, no bathing; check daily for redness, discharge or loose stitches.
  • Give the pain relief on schedule. Cats hide pain; do not stop because your cat "looks fine".
  • Metabolism drops by 20 to 30% after neutering, so adjust food to avoid weight gain.
Contact us straight away if the wound bleeds or opens, vomiting continues, your cat has not eaten for 24 hours, the gums look pale, or breathing is fast.

Cost

The fee depends on weight, sex and whether blood tests are needed. We give a written estimate when you book, and nothing is added before surgery without your agreement. See our article on how vet fees work.
