Spaying and Castrating Cats
Neutering queens is known ’spaying’, the procedure usually involves the surgical removal of the uterus and ovaries or ‘ovario-hysterectomy’
Cat Spaying
Advantages
- Prevents the queen from breeding and producing unwanted kittens.
- Dramatically reduces the risk of mammary cancer.
- Prevents seasons and the behaviour changes, roaming and attractiveness to males that accompanies them.
- Prevents pyometra, this is a condition where the womb becomes infected and full of pus – it is life threatening.
- Dramatically reduces the risk of uterine and ovarian cancer.

Disadvantages
- Spaying is a surgical procedure, as with all surgical procedures there is a very small risk from the anaesthetic and the surgery. This risk is far smaller than it used to be with the advent of new anaesthetics and surgical techniques.
- The queen will need to be confined to the house for 10 days after the operation.
- There may be some pain for a few days afterwards, this can be controlled very effectively with painkillers available from your vets.
- Some evidence that it may increase the risk of urinary problems.
In a young, healthy queen these drawbacks are vastly outweighed by the advantages to your queen’s health of having her spayed, if you are not planning to breed from her.

- Reduces the risk of a cat contracting Feline Immunodeficiency Virus (FIV) and other infectious diseases.
- Castration is a surgical procedure, as with all surgical procedures there is a very small risk from the anaesthetic and the surgery. This risk is far smaller than it used to be with the advent of new anaesthetics.
- There is some evidence that castrated cats are at higher risk of urinary problems.
Disadvantages
