Benefits of Desexing

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.

When should cats be desexed?

Cats can be pregnant from four to five months of age.  To prevent accidental or early litters, kittens can be safely desexed from two months of age and over one kilogram in weight.

AWLQ Veterinarian Dean Tait says: “It is an easier operation causing less stress and a quicker recovery when they are kittens.”

Desexing your cat also has positive advantages for its behaviour.  Desexed animals are less likely to wander, to mark their territory by spraying, or to be aggressive.

“There is no medical reason why an animal should have a litter first.  In fact undesexed female cats and dogs are more prone to certain cancers such as mammary tumours and undesexed males to prostate problems,” AWLQ veterinarian Dean Tait said.
