Orange-and-white guinea pig with patchy fur

I lost my orange-and-white guinea pig yesterday around 3pm after she squeezed out through a slightly open cage door. She's about the size of a small grapefruit, with fluffy fur, white belly, and an orange back. She has a tiny black dot on her right ear and wears a light blue ribbon with a tiny bell that jingles when she moves. I think she wandered toward Market Street and the Susquehanna Riverwalk, possibly near the Market Street Bridge or around the downtown Williamsport riverfront. I'm really worried—she's shy with strangers and this pet has sentimental value; it was my daughter's birthday gift last year, and it's hard to sleep knowing she's out there. If you’ve seen her, email me at [email protected].
