We are proud to offer residents with a Kingston postal code, a low-cost alternative to getting your cat spayed or neutered. This is the first permanent low-cost spay/neuter clinic in Kingston and we hope that someday, it will be offered more regularly.

As it stands right now, the Kingston Humane Society’s Low Cost Spay/Neuter clinic will operate once a month. The cost will $125 for either a spay or a neuter. In addition to the spay/neuter procedure, we will offer the opportunity to microchip your cat and provide them with flea treatment. These treatments will come at an additional charge:
Microchip - $20+HST
Flea Treatment - $15+HST

The Kingston Humane Society would like to thank The City of Kingston for the funding they provided that allowed us to purchase a second operating table, a second anesthesia machine and a second light along with a few other items. They are also supporting our veterinary team to receive training in high volume spay/neuter procedures which will take place as soon as the training centre in North Carolina is back up and running.

Frequently Asked Questions


If I have more than one pet, do I need to submit more than one application form?

Each pet requires its own application, which will remain part of its medical record.

How does spaying or neutering my cat prevent reproduction?

In female cats, the uterus and ovaries are removed through a small incision in the abdominal wall. After the surgery, females will be unable to get pregnant and will not go through heat cycles. In male cats, the testicles are removed but the scrotum remains. Removal of the testicles prevents production of sperm resulting in a male that cannot produce young.

Will my cat be unable to reproduce immediately after surgery?

Female cats will be unable to reproduce as soon as the surgery is complete. They will have no reproductive organs remaining. Male cats will have their testicles removed but there will be sperm and testosterone in their systems for up to three weeks post-surgery.

What are the benefits of spaying or neutering my pets?

  • It reduces or removes the risk of disease, infection and cancer of the pet's reproductive system i.e. mammary cancer, prostate cancer, uterus infection (pyometra).
  • Female heat cycles are eliminated.
  • Male cats may no longer spray or smell, male dogs may urine mark less frequently on walks.
  • It ends the cat's crying, howling, fighting and frantic efforts to get out, and may decrease a dog’s urge to run away in search of opportunity to mate.
  • Spaying and neutering can make your pet more laid back and affectionate by decreasing hormonally related aggression issues.
  • Spayed and neutered pets have been proven to live longer lives. Male neutered cats for example live 62% longer than unneutered toms.
  • It reduces pet overpopulation and the thousands of homeless and unwanted animals that end up in rescue organizations and shelters each year.
