The Anti-Cruelty Society 

Our Mission

Building a community of caring by helping pets and educating people.

The Anti-Cruelty Society is also known as the SPCA of Illinois, 157 W. Grand Avenue, Chicago, Illinois 60654, (312) 644-8338, Tax I.D. Number: 36-2179814.

The Anti-Cruelty Society is committed to caring

The Anti-Cruelty Society shall:
  • Provide compassionate care for any animal in need
  • Attempt to find a home for every healthy or rehabilitatable dog and cat that comes to us
  • Intervene to prevent cruelty to animals
  • Partner with the community to educate on animal issues and inspire compassion and respect
  • Provide low or no cost spaying or neutering


We will provide the best quality animal care through:
  • Collaboration—only through partnerships and relationships can we achieve our mission
  • Excellence—we will strive to have a best practice model in all that we do
  • Professionalism—we will act with integrity and in an ethical manner
  • Leadership—we will plan for the next generation of issues that will impact our organization,
    our community and pets
  • Communication—we will fearlessly outline and communicate our commitment
    to being advocates for animals
  • Transparency—we support the Asilomar Accords and proudly and publicly report our statistics


At The Anti-Cruelty Society we believe:
  • In an open door policy—we will not turn away any animal in need
  • There are no time limits placed on any animal in our care
  • That no healthy or rehabilitatable pet should be euthanized
  • The key to pet overpopulation is sterilization
  • That education can prevent cruelty, abuse and neglect and promote responsible pet ownership
  • If an animal’s quality of life is severely compromised, euthanasia is the humane alternative

Since 1899...

Since 1899, The Anti-Cruelty Society has been committed to caring for animals and the community.

Our Second Century

Since 1999, the beginning of our second century of caring, we have found loving permanent homes for more than 40,000 pets, spayed or neutered more than 61,000 animals and taught messages of compassion and caring for the animals to more than 225,000 school-aged children and community groups.


Services & Resources

In addition to receiving and caring for thousands of animals each year, we provide a wide variety of services and resources. These include an adoption program, a low-cost spay/neuter clinic, a rehabilitation & treatment center, a low-income clinic, humane education/community outreach, cruelty and abuse investigations and rescue, dog training classes, a free behavior hotline, and pet visitations.


The Anti-Cruelty Society is a founding member of the Chicago Animal Shelter Alliance (CASA).  CASA was formed in 2002 by a coalition of Chicago shelters who realized that by working together, we could consolidate our efforts to reach a wider audience, and make a greater impact. Since that time, the organization has grown to include the entire shelter community in Chicago, and much of the veterinary community as well.
