The Secret of Nimh mice were part of an OOPSIE litter in their previous home. They became too much for one person to care for, so they are looking for new homes! Their foster parent says: These girls are all housed together and they are so active, very social, and very curious and incredibly sweet. They live napping the days away together and playing and exploring together. They love banana chips I made. They also love being up close and personal with you inspecting everything youre doing to their area.
