Since 1935, the Michigan Anti-Cruelty Society (MACS) has dedicated its efforts to providing refuge to stray, injured, and forgotten animals. We work to promote humane education and actively initiate affirmative legislative action. MACS provides extensive sheltering, veterinary care and pet adoption services to the thousands of animals that pass through the shelter doors. We never turn away an animal in need. For many animals, MACS is their only hope.



Due to Covid-19 restrictions, we are no longer allowing the public into our shelter or clinic without an appointment. Please call the shelter at (313) 891-7188 to schedule an appointment to drop off an animal or to pick one up if you did an online adoption. Please call the clinic at (313) 369-9863 to schedule an appointment with them. All clients with an appointment must wear a mask while inside the shelter or clinic.

With Fall arriving just around the corner, we at MACS decided it would be a perfect time to share some of the many changes we have made to improve our efforts to care for animals. Click HERE to view them. We appreciate everyone’s time and patience while MACS has embarked on this journey.



The Michigan Anti-Cruelty Society is funded completely by private donations. “MACS never turns any animal away or charges for the shelter and rescue services we render to animals that cross our threshold if people cannot afford a donation.

MACS is a registered 501(c)(3) non-profit charity supported entirely by donations. MACS is proud to have received a four star rating from Charity Navigator. Charity Navigator is America’s premier independent charity evaluator. Click on the logo to review our four star rating.

MACS credo is ‘the animal comes first’ and we will continue to serve the Detroit community and environs with this service through the actions of your generous support.”

Rescue Vans

MACS has two rescue vans on the streets of Detroit five days a week. Our drivers perform hundreds of animal rescues, pick-ups and cruelty investigations each year.

Our rescue vans were donated through the generosity of the Oliver Dewey Marcus Foundation.
