spay & neuter prices

The Windsor/Essex County Humane Society Veterinary Clinic is accredited by the College of Veterinarians of Ontario to offer services to the public. The primary focus of the clinic is spaying and neutering, although other services such as vaccines, microchips, and parasite treatments are offered at the time of surgery or on specific wellness services days.


The clinic is a high volume, self sustaining operation. Everyone is welcome to use it, regardless of geography or income level.

Cat Spay or Neuter


Price includes spay or neuter only.

Please note that patients may be declined at the veterinarian’s discretion if their weight, reproductive history or other factors make the surgery too high-risk. Our clinic is focused on low-risk surgeries. If surgery is performed on a high-risk pet who requires additional surgery time or fluids, an additional fee of up to $50 may be charged.

Community Cat Package


Cats must arrive in a live trap to qualify.


The Windsor/Essex County Humane Society spay neuter clinic is actively assisting individual caregivers and groups working on TNR programs. To help keep the free-roaming population healthier, a community cat package is provided at no additional charge for feral cats. The package includes an ear tip, microchip, and FVRCP vaccine. Learn more about TNR HERE.

Please note that patients may be declined at the veterinarian’s discretion if their physical condition or presentation indicates that the surgery is too high-risk.
