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.


  • 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 tumours, acute uterine infections and breast cancer in females, and also other diseases like mammary cancer, perianal tumours and perianal hernias.
  • 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 behaviours. 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.


  • Reduces the cost to the community of having to care for unwanted 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 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 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.
