Cat Castration

Before the procedure takes place, we ask that you, (the owner) read this information carefully as it provides you with knowledge ready for the elected procedure. All surgical procedures undertaken carry associated risks and complications. Although rare, we want you to be fully informed before you proceed.

Starving is required for patients undergoing a general anaesthetic. We recommend feeding dinner as normal, but then no food to be given after midnight, and no breakfast on the morning of the surgery. Water is allowed and can be removed when you get up in the morning. If the animal is less than 4 months old then the starving instructions may differ slightly. We would advise that you contact the surgery at for further guidance.

The procedure your cat will be having is called a castration. This surgical procedure involves removing both testicles but leaving the scrotum in place. Once this procedure has been performed it cannot be reversed. Benefits to your cat include:

  1. May reduces the urge to spray, and if they do the scent should be less pungent
  2. Prevent unwanted pregnancies and may reduce the urge to roam
  3. May reduce aggressive instincts and therefore fighting

Please read the following list of complications that can result from this procedure and ask a member of staff if you have any questions or concerns. This list is not exhaustive. Should an accepted complication arise, owners are liable for the costs associated with the complication.

  1. Anaesthetic death
  2. Haemorrhage (bleeding) both during and after the procedure (inside or outside of the abdomen)
  3. Wound break down
  4. Wound infection
  5. Bruising and swelling
  6. Seroma (pocket of fluid)
  7. Damage to the penis
  8. Pain
  9. Suture material reaction
  10. Risk of injury on recovery post-operatively
  11. Clipper rash or skin reaction to surgical scrub

We take precautions to minimise these risks to your cat, however on occasion complications do arise. We do offer post-operative checks at 3 days post-surgery to monitor your cat’s recovery.
