Why you should consider spaying or neutering your pet
by Ontario SPCA and Humane Society | General Pet Care | August 1, 2025

When it comes to responsible pet parenting, spaying or neutering your animal is one of the most important decisions you can make. Not only does this surgical procedure help prevent unwanted litters and reduce pet overpopulation, but it also offers a range of health and behavioural benefits that can lead to a healthier life for your furry friend.
Health benefits for your pet
Spaying (for females) and neutering (for males) significantly reduces the risk of several serious health conditions. For female animals, spaying eliminates the risk of uterine infections (pyometra) and greatly reduces the chance of mammary tumors. For males, neutering prevents testicular cancer and lowers the risk of prostate problems.
Additionally, spaying or neutering can contribute to a more balanced temperament. Unaltered animals are often more likely to roam, mark their territory, or show aggression. Spaying or neutering reduces these behaviours, making them safer and more manageable companions.
Helping prevent pet overpopulation
Every year, thousands of cats and dogs across Ontario are abandoned or brought to shelters for rehoming as a result of unplanned litters. Spaying or neutering your furry companion is a direct way to reduce the number of homeless animals in our communities. Fewer unwanted pregnancies means fewer animals in need of care, and more resources available for the animals already waiting for loving homes.
A compassionate choice
Animals adopted from the Ontario SPCA and Humane Society are spayed or neutered, vaccinated and microchipped prior to adoption. This means that when you adopt, you’re not only giving a deserving animal a second chance, you’re also bringing home an animal who has been given the best start possible on their journey to a happy, healthy life.
Choosing to spay or neuter your pet is a compassionate, proactive step that benefits your animal, your community, and the broader effort to reduce the number of homeless pets. Whether you’re a current pet parent or considering adoption, know that this small act makes a big difference.
