Benefits of Desexing

If you live with a companion animal the most important thing you can do is to ensure they are desexed. Every year in Australia approximately 200,000 healthy cats/kittens and dogs/puppies are destroyed in council pounds and shelters – see

Desexing saves innumerable lives, improves health, increases life span, and promotes positive social behaviours.  If you are experiencing financial difficulty there are many subsidised desexing programs available in Australia to help you meet these costs. See for more information.

The cat numbers on the streets are so out of control now, the only way to deal with over population is to desex. Everyone can make a difference. Desexing owned cats and strays is absolutely vital. Females will have on average around 12 to 16 kittens per year. By the time mum is having her third litter for the year, her first kittens will be having their first litters. That is a dreadful amount of kittens, from just one mum, in just one year. These numbers are why desexing makes such a huge difference.

Very sadly, as the stray cat population rises and their health deteriorates due to lack of care and nutrition, we are seeing babies being born with higher rates of birth defects, causing even more suffering on the streets.

Desexing female cats prevents:

  • Mammary Cancer – The third most common tumour found in female cats. If a cat is desexed before she has her first heat cycle, there is an extremely low chance she will develop it.
  • Pyometra – an infection of the uterus which is fatal if not treated.
  • Feline Immunodeficiency Virus (FIV) –  female cats can be infected with FIV when they mate.
  • Injury –  undesexed female cats are prone to wandering in their search for mates, placing them at enormous risk of being hit by cars. They can also sustain injuries during mating or fighting.
  • Pregnancy and lactation – Multiple litters deplete mums’ bodies badly, having a negative impact on their health and immune system.

Desexing male cats prevents:

  • Injury – Undesexed males wander, putting them at great risk of injury and death.
  • Testicular cancer, Prostate cancer and other associated issues – early desexing significantly reduces the risk of infections, cancers and prostate enlargement.
  • Feline Immunodeficiency Virus (FIV) – undesexed male cats are driven to aggressive and territorial behaviour because of the excess testosterone in their bodies. They are at a huge risk of contracting diseases such as FIV when they fight with other cats.

Feline Immunodeficiency Virus (FIV)

Feline Immunodeficiency Virus, also referred to as Feline AIDS, is infectious and attacks certain cells in the cat’s immune system and they can become ill.

Undesexed cats are the main transmitters of FIV which happens during fighting and mating.

Desexing cats reduces these behaviours, thereby reducing the spread or contraction of FIV. There is a vaccine, however it is unknown how fully it protects.

Early age Desexing

It used to be thought that cats could become incontinent if desexed too young. This is not the case . The reality is most kittens can fall pregnant by 16 weeks of age which has a very negative affect on their health. Many vets will desex young kittens at 1.2kg. Ask your local rescue groups for recommendations of vets.

Not Enough Homes

In the last few years we have seen the number of strays cats rise exponentially. This is in part due to how quickly cats breed, but we have also seen a huge rise in people dumping (often undesexed) cats on the streets. There are now so many stray cats (often friendly) and rescuers can no longer keep up. Kitten season is now so intense that pounds and rescues are often at capacity and can’t take in stray kittens or mums with babies.

CatRescue901 and other rescues are contacted on a daily basis to take in mums and babies and often do not have space to take them.

If you let your cat have kittens don’t assume you will get help. NEVER give away kittens for free. It places them in danger. Some people disguise themselves as respectable, but feed kittens to snakes or use them to bait dogs or enjoy harming them. Also giving away undesexed kittens usually contributes to the over population problem when they start to breed.

The true cost of Desexing and not desexing

Desexing your pet is a basic and vital part of being a responsible pet owner. If you are experiencing financial difficulties there are organisations which have created subsidised desexing programmes to help you meet the costs involved. See

If you don’t desex your cat and she has kittens, the ongoing costs of caring for the kittens and mum would out way the original cost of desexing.

In some circumstances CatRescue may be able to assist with the cost of desexing a cat. Please go here for more information.
