Fostering Application

Fostering is a year-long commitment. You must be able to foster for a year and bring the guinea pig you foster to the adoption meet we host one time per month in central MD (located between Baltimore, Washington, and Frederick County, MD). Fostering is not means to try out a guinea pig before adopting.

MGPR wants your foster care experience to be a comfortable and positive one. We will make the best match possible for you, your family members, your lifestyle, and your environment.
