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.

Using a successful model from a nationally known organization called Humane Alliance, (www.humanealliance.org) we transformed our former facility into a surgical center.  Our goal is to alter up to as many as 35 dogs, cats, puppies or kittens per day.

The crisis of pet overpopulation in our community is staggering.  Preventing unplanned and unwanted litters is a large part of the solution and by providing a low-cost, high-quality resource for the community, we can make a difference.
