Grey dwarf rabbit with blue harness

I lost my grey dwarf rabbit yesterday around 3pm on the CSU campus, near Laurel Street and the Lory Student Center in Fort Collins. It's a small rabbit with soft grey fur and a white underbelly, about the size of a small loaf, and it's still wearing a light blue harness with a tiny silver bell. There are a couple of unique markings: a small notch in the left ear and a white patch on the chest. This rabbit was a gift from my grandmother and has sentimental value; I really need it back.
