The National Desexing Network (NDN) is a nationwide referral system for discounted desexing made available to pet owners in financial need. Our goal is to end pet overpopulation by making this service more affordable to those who might not otherwise be in a position to desex their pets.

Australia has one of the highest rates of pet ownership in the world. Four out of five Australians have owned a pet at some time, and almost two-thirds of Australian households currently own pets. Despite these figures, around 23 cats and dogs die every hour of every day in pounds and shelters nationwide. Due to the ongoing problem of pet overpopulation, these healthy, loving animals are being killed because there are not enough homes available.

Established in 2004, NDN has a nationwide network of more than 160 participating veterinary clinics and to date has helped to desex around 200,000 cats and dogs nationwide.

Every year in July (please note that the 2020 National Desexing Month has been moved to September) NDN organises National Desexing Month, which has been a big success since its inaugural year 2005 and has continued to grow from then. During the month, welfare organisations, veterinarians, pounds and councils are invited to participate by encouraging pet owners in their communities to desex their pets before the summer breeding season.

Together with the parent organisation, Animal Welfare League Queensland, NDN has also organised four National G2Z Summits to End Companion Animal Overpopulation.  The summits aim to bring together all stakeholders to share challenges and effective strategies and to set targets to reduce the numbers of animals euthanised in Australia.

The NDN concept is based on SPAY/USA, a well established desexing network in America. In the last 18 years, SPAY/USA has facilitated 100,000s desexing procedures, thereby causing a significant drop in the numbers of pets euthanised annually. To date, more than 7,000 vets have joined SPAY/USA.

NDN is a charity program funded through the generosity of members of the public who strongly believe in desexing. The only beneficiaries of the program are Australia’s cats and dogs.


There are many reasons why pet owners should desex their pets. As well as helping to stop pet overpopulation, the following are some of the other benefits associated with desexing cats and dogs.


  • Reduced risk of getting cancer or other diseases of the reproductive organs, such as testicular cancer, prostate cancer/disorders in males, and cystic ovaries, ovarian tumors, acute uterine infections and breast cancer in females, and also other diseases like mammary cancer, perianal tumors and perianal hamias.
  • Females can suffer from physical and nutritional exhaustion if continually breeding.
  • Pets generally live longer and healthier lives.


  • Pets are less prone to wander, fight, and are less likely to get lost or injured.
  • Reduces territorial behaviour such as spraying indoors.
  • Less likely to suffer from anti-social behaviors. They become more affectionate and become better companions.
  • Eliminates “heat” cycles in female cats and their efforts to get outside in search for a mate.
  • Eliminates male dogs’ urge to “mount” people’s legs.


  • Reduces the cost to the community of having to care for unwanted puppies and kittens in pounds and shelters.
  • No additional food or vet bills for the offspring.
  • No need to find homes for unwanted or unexpected litters of puppies or kittens.
  • Save money from expensive surgeries from car accidents or fights, which are less likely to occur if your pet doesn’t roam around.
  • Dumping puppies and kittens is an ethical cost, as well as being illegal and inhumane.
  • The price of desexing is more affordable to those in financial need with the assistance of organisations such as NDN.
