Humane Society of Southern Wisconsin

Constant Companion

The Humane Society of Southern Wisconsin was founded by a group of caring people who loved and respected animals and recognized the value an animal shelter can add to a community. To this day, this non-profit organization couldn’t continue its important work without the generosity of the compassionate supporters that make up our community, people like you. 

When you become a constant companion, you make a beautiful difference for our pets every single day. Your recurring donation helps the thousands of animals we care for each year, keeping them fed, healthy, clean, and happy. It also helps us promote successful adoptions so lost and homeless pets find loving homes as we educate our community about animal care and ownership. Most tenderly, it’s an investment in the lives of all the kittens, cats, puppies, dogs, and other fuzzy and feathered friends we serve. Become a constant companion today!

Be sure to mark that you would like to show your support by making your donation a monthly donation.
