Every tail wag, purr, and second chance starts here.

At Mary S. Roberts Pet Adoption Center (MSRPAC), we believe every cat and dog deserves a loving home. Since 1897, we’ve been Riverside’s trusted safe haven for homeless pets—providing shelter, veterinary care, and adoption services for thousands of animals each year.

We are a nonprofit 501(c)(3) animal shelter in Riverside, CA, funded entirely by private donations and community support. Our mission is to eliminate the suffering of homeless cats and dogs by providing compassionate care, facilitating adoptions, and addressing pet overpopulation through education and spay/neuter programs.

What We Do
As a limited-entry companion animal shelter, we:

Accept healthy, adoptable cats and dogs from owners who can no longer care for them
Partner with local shelters to rescue pets at risk of euthanasia in Riverside County
Provide full veterinary care, vaccinations, microchipping, and spay/neuter services
Offer temporary foster care for underage or recovering animals
Match pets with families through an adoption process focused on personality, lifestyle, and long-term compatibility
No healthy, adoptable animal is ever euthanized. Every pet remains in our care until they find a good, loving home.
