Spay/Neuter Clinic and Online Scheduler

Please read the following information before scheduling an appointment:

Spaying or neutering your pet is one of the most important things you can do for him or her. The Anti-Cruelty Society’s clinic is able to offer these important surgeries at a greatly reduced price thanks to the generosity of our committed donors.

Dog and cat spay/neuter appointments are Monday–Friday


  • Cats: $25 male or female
  • Feral cats are free
  • Dogs: $130 (Male and Female) (except pit bull and pit bull mixes)
  • Pit bull and pit bull mix dogs: $60

For many years we provided pit bull surgeries at no charge. With increasing pressures on our resources we are implementing a discounted fee of $60. This fee does not reflect the true cost of this valuable service, but it will help us to continue to provide this lifesaving program for the greatest number of animals. If you are unable to afford even this modest charge, please refer to our Charity Veterinary Clinic page for information to qualify for this program.

All appointments must be pre-paid for the cost of the surgery online via credit card (or debit card with a logo). You may cancel your appointment with at least 48 hours notice and the charges will be reversed. No refunds will be given for missed appointments. 

Additional Services Available at the Time of Surgery:

  • Canine/feline distemper vaccination – $15
    The Anti-Cruelty Society requires that all animals have a current distemper vaccination.
  • Microchip – $25
  • Feline leukemia/FIV Test  – $25
  • Rabies vaccination – $20
    The county requires that all animals have a current rabies vaccination.
  • Canine Influenze Vaccine – $25
    With the canine influenza virus (CIV) now being considered endemic in Chicago (meaning the virus remains in our community), we highly recommended that dogs in the region be vaccinated with the H3N2 vaccine. This new vaccine may not completely prevent infection but has been shown to shorten the length of illness, lessen the severity of symptoms, and reduce the shedding of virus into the community. Most infected dogs survive, but treatment for this disease can be very expensive and every dog you encounter can be a source of infection.This newly developed vaccine is now available for your dog through The Anti-Cruelty Society’s affordable spay/neuter program. It does require a booster vaccine at your local veterinarian’s office 3 weeks later. The vaccine should impart protection 2 weeks after the booster vaccine.


Spay and neuter surgeries require no overnight stays. The day of your appointment, please bring your animal to our clinic between 8 a.m. and 9 a.m. Cats must be in a carrier, dogs must be on a leash or in a carrier. If you arrive before 8 a.m. please wait in our first floor lobby at 169 W. Grand Ave. Please allow additional time so you and your pet can meet briefly with a veterinarian.

You will receive a refund within 7-10 business days.
