Reproductive Care For Cats & Dogs

Spaying and neutering are common surgeries used to remove your cat or dog's reproductive organs, rendering them unable to reproduce. These preventive care procedures should be considered by every responsible pet owner.

Having your pet spayed or neutered can help them live a healthier, more contented life with fewer behavioural problems like aggression or roaming. Spaying and neutering can also significantly reduce the risk of certain types of infections and cancers.

For many people in Thornhill and the surrounding communities, one of the primary benefits of spaying or neutering their pets is to help prevent litters of unwanted dogs and cats. This can help reduce the population of homeless pets, as well as those in overcrowded animal shelters.

Spaying & Neutering, Thornhill Veterinarians

Neutering (Males)

Neutering, or orchiectomy, is a surgical procedure where the testicles are removed from male cats or dogs. This prevents them from being able to father any young.

Cats: Neutering your cat can help curb undesirable behaviours such as spraying, roaming and aggression towards other cats.

Dogs: Neutering your dog may help reduce animal aggression, 'humping' and attempts at escaping your home or yard.

Spaying (Females)

Spaying, technically known as an ovariohysterectomy, removes a female companion's reproductive organs. This procedure with prevent your cat or dog from becoming pregnant.

Cats: Spaying your cat may help prevent your kitty from escaping your home, roaming, yowling and urinating inappropriately.

Dogs: Having your female dog spayed ends their heat cycle and helps prevent pyometra (womb infection) and mammary tumours.

When to Spay & Neuter

Your veterinarian has a clear understanding of your companion's health and medical needs. Although we provide general spay and neuter age guidelines below, you should always discuss treatment with your veterinarian before making any decisions.


You can spay or neuter a kitten as young as six to eight weeks of age, however standard spay and neuter surgeries are most often performed when the kitten is between five and six months old.

That said, a healthy adult cat of any age can also be spayed or neutered.


Puppies can typically be safely spayed or neutered when they are around six months old. However, some veterinarians have concluded that it is better to wait until the dog has reached sexual maturity before performing these reproductive surgeries.

Speak to your veterinarian to determine the best time to have your dog spayed or neutered and what to expect with the procedure and recovery.

How Spaying & Neutering Pets Benefits the Community

Overcrowded shelters often resort to euthanasia as a means of population control. Spaying and neutering help reduce stray overpopulation in animal shelters.

This allows shelters to allocate resources efficiently, focusing on providing better care and finding loving homes for the animals already in their care.

Additionally, with fewer stray animals, communities are safer and more pleasant for residents, mitigating conflicts between animals and humans.
