At Mt Martha Vet Clinic we understand how much your feline friend means to you. Neutering is a once in a lifetime event and we are dedicated to ensuring your cats operation is performed safely and successfully.

What is involved in desexing?

On the morning of surgery your cat is weighed and given a physical examination. A sedative injection is given which relieves anxiety & provides pain relief. An intravenous (iv) catheter is placed and general anaesthesia is induced by injection through this catheter and anaesthesia is maintained with a mixture of gas and oxygen via a tube placed in the throat. The anaesthetic is constantly monitored and recorded by a nurse. The surgical site is clipped and prepared and antibiotic is given The vet performs the surgery in sterile conditions using human grade suture materials. At the end of the surgery additional pain relief is given. A tattoo is placed in the left ear so that your pet is identified as desexed. Afterwards your cats recovery is closely monitored. Food is offered and the iv catheter is removed once we are happy with their recovery.
In MALES both testicles are removed (castration).
In FEMALES the uterus and the ovaries are removed in full (known as a spay).

At discharge we give you written instructions on postoperative care. Our fees include a check up at 2-4 days and for females stitch removal at 10-14 days after surgery. In male cats no stitches are required. In the vast majority of cases your cat goes home on the day of surgery. For your convenience, they can be admitted the evening before surgery, or they can be accommodated afterwards if needed (an extra charge applies).


Desexing involves a general anaesthetic and we advise pre anaesthetic blood testing and IV fluids to increase the safety of anaesthesia. More information is provided on the pre anaesthetic form.

What are the benefits of desexing?

There are not enough homes for all the cats and kittens born in Australia. As well as unwanted kittens there are a number of health and behavioural benefits for your cat


  • Decreased roaming behaviour greatly reduces the risk of straying and road accidents.
  • Aggressive and dominant behaviour to humans and other cats is much reduced.
  • Testicular cancer cannot occur.
  • The Feline Aids virus (FIV) is transmitted by fighting. Desexing male cats by reducing their tendency to fight helps reduce the spread of this incurable cat disease.
  • Castration is 95% successful at stopping spraying where a male cat will mark its territory (ie your house) with a very unpleasant odour.
  • The other main advantage of castration for your cat is that he will be much more content, otherwise his natural urge to reproduce cannot be satisfied.


  • Infection of the womb (pyometra) is a life threatening condition, the risk of which is eliminated by spaying.
  • Breast cancer is extremely rare in spayed female cats.
  • A spayed cat avoids the risks and costs associated with pregnancy and giving birth.

At what age can my cat be neutered at Mount Martha Veterinary Clinic?

We advise desexing at 5 months of age. Desexing may be performed much younger than this but there is an increased anaesthetic risk in younger patients and more monitoring is required. Cats become sexually mature from 6 months of age we advise catching them before they reach the point where they can produce kittens (as lovely as they are!)
