The Mary S. Roberts Pet Adoption Center (MSRPAC), located in Riverside, California, is dedicated to providing animals—especially cats and dogs—with second chances. They operate a full adoption center with procedures and programs to match animals with suitable homes, and maintain a foster program for those needing extra care. In 2025 alone, they had facilitated 1,572 adoptions (as of September), aiming for a goal of 2,100.

Beyond adoption, MSRPAC offers a wide spectrum of services and community programs. They run low-cost clinics for vaccination, spay/neuter services, a pet food assistance program, and education efforts around responsible pet ownership. They also host behavior training, reading programs, student engagement initiatives, and community events to raise awareness and support.
