Generally all dogs and cats that are not breeding should be desexed.


DID YOU KNOW? : That a female cat cycles every 21 days, and that they can be in season and able to mate for 13 days each cycle?!

So the chances of them getting pregnant in the breeding season is very high.

DID YOU KNOW? : That if a female dog is desexed before their first season that their chance of getting cancer in their mammary glands is almost nil?!

Female dogs and cats that are not desexed may have unwanted litters, and are more likely to develop infections of their uterus and mammary cancer.


Male dogs and cats that are not desexed have more drive to fight and escape to chase the”girls”. They are susceptible to prostate and testicular disease. Male cats have a very strong urine smell when marking their territory, and their desire to fight is enormous. Unfortunately, so is the chance of them contracting Feline Immunodeficiency Virus (cat aids).


We recommend that dogs and cats be desexed at 6 months of age.

Yes, this is before the females’ first season, because they don't need a litter to be a great dog.

This is the age that we recommend that all cats and dogs have their: 

  1. Desexing
  2. Microchip placed (if not already done)
  3. First Yearly Heartworm Injection (dogs only)


Remember, during Desexing, at Peninsula Veterinary Surgery, we use the most up-to-date anaesthetics, all patients are given intravenous fluids during surgery, and kept warm on a heating pad.

To assist in recovery, pain relief and antibiotic cover are administered. Throughout surgery and the recovery period, patients are monitored carefully.

Most are ready to go home the same day of surgery, and ten days later, we will remove any stitches and check the surgery site.

All this is included in the fee you are charged.
