COVID-19 (Coronavirus) Update

What shelter-in-place means for animal shelters.

Mary S. Roberts Pet Adoption Center will be open from 10am – 4pm by appointment only. To schedule an appointment to adopt an animal, please email .

We will continue to provide the following services to our community:

  • The Mary S. Roberts Pet Adoption Center’s Pet Food Assistance Program feeds 100’s of dogs and cats each month in coordination with different partner organizations throughout the community.  Our Pet Food Assistance Program is also available to anyone who is experiencing financial hardship and might need a little help providing food for their beloved pet(s). We coordinate individual pet food packaging and delivery to those in need and in these times that includes pet owners who are struggling with the loss of employment due to the COVID-19 outbreak. Food can be picked up from the Center Thursday – Saturday from 10am – 1pm.
  • Owner relinquishments of puppies and kittens under 8 weeks of age by appointment only.  To schedule an appointment please fill out the form on our website
  • Fostering animals is especially critical right now, since we anticipate fewer people will be coming in to adopt pets amidst the COVID-19 outbreak. Thanks to our incredible volunteers, we do not currently need fosters, but that may change in the coming days. If you would like to help us be prepared for that eventuality, you can sign up here.

Who We Are

The Mary S. Roberts Pet Adoption Center (MSRPAC) is a non-profit 501(c)(3) public benefit charitable organization committed to giving homeless cats and dogs another chance for a healthy and happy life by finding them good, loving homes. MSRPAC is supported solely by private donations and fundraising projects.

As a limited-entry companion adoption center, the Pet Adoption Center takes in healthy, adoptable cats and dogs from owners who can no longer care for them. As space allows, we also select healthy, adoptable cats and dogs from other local animal welfare agencies. Pets that are accepted into our center must pass health and behavior evaluations. All animals stay in our care until a good, loving home is found. No healthy, adoptable animal is ever destroyed. If space is not available to admit a pet, or if the pet cannot be accepted due to any other reason, owners are referred to other facilities and organizations.

All pets while in our care receive food, a comfortable environment, medical attention and loving socialization from both staff and volunteers. Our staff and volunteers monitor the physical, emotional and mental health of the animals daily. A progressive “stress reduction” program helps keep our residents healthy, happy and adoptable. All animals are vaccinated, micro-chipped and spayed or neutered. For animals that are too young to be adopted, volunteers offer temporary homes through our pet foster care program.

Our Adoption Counselors assist in finding the right pet based on personalities and lifestyle. Individuals who adopt our animals go through an extensive adoption process where they are counseled on the medical, physical and emotional needs of the particular dog or cat they are adopting. After the adoption, the staff and volunteers at the center are always available to help with any questions or issues that may arise.

Caring for homeless pets is not all the Mary S. Roberts Pet Adoption Center does. MSRPAC is very active in promoting animal welfare and positive human-animal relations through community-service programs which include humane education, pet behavior counseling, and support of pet overpopulation education and programs.

More than 100 years of caring

The Riverside Humane Society was established in 1897 for the purpose of preventing cruelty to children and animals. The first shelter was dedicated in 1917 and housed dogs, cats, horses, cows, birds, chickens and more. The society was incorporated in 1929 and in 1956 moved to 5791 Fremont Street. RHS provided complete animal control services such as licensing, impounding stray animals, accepting owner turn-ins, and investigating animal cruelty and aggressive-animal reports. Then in 1995, the society relinquished all animal control responsibilities to the County of Riverside Dept. of Animal Services and reorganized as the Riverside Humane Society Pet Adoption Center. In January, 2008 RHSPAC relocated to a newly constructed, 17,000 s.f. facility at 6165 Industrial Avenue.  On March 3, 2010 the Riverside Humane Society Pet Adoption Center officially changed their name to the Mary S. Roberts Pet Adoption Center.
