It's important that your pet receive yearly vaccinations to keep them safe. Visit our low-cost clinic to keep your pet healthy.


Providing a low-cost, high-quality resource for the community, we can make a difference. Book an appointment today.


As a volunteer, you will be making a difference for the animals as well as your community. Learn how to join our team.

Relinquish or Rehome

Often a pet is surrendered because an owner feels they have no choice. We may be able to help find alternatives to surrendering.

Adoptable Pets

When you open your home to a pet who needs help, they really do show their appreciation for the rest of their life! Adopt today!

Welcome to MSRPAC

Welcome to the Mary S. Roberts Pet Adoption Center website. We appreciate you taking the time to visit our animals and learn more about us. Please know that your support saves lives. When you adopt, donate, volunteer, advocate, join us at an event or shop at our pet and thrift stores, you are giving second chances to pets in need.

What Our Community Says

  • The Mary S. Roberts Pet Adoption Center is THE place to adopt your new furry family member.
    I adopted my two kittens from this facility, and the experience was a complete joy.
  • The cleanliness of the center and the caring personalities from all of the staff and volunteers places
    the whole environment seem warm and inviting. We are so thankful to everyone at MSRPAC
    for embracing our family and allowing us to adopt new additions.
  • We love this place everyone is so helpful. I love seeing the employees and volunteers
    all interact with the animals, taking them for walks, playing with them, giving them extra love, and making
    sure everyone who touched the animals have their hands clean. We adopted a 7 month cat and he is the happiest cat ever.
