Lost: Tiny tan hamster with white belly

I lost my tiny tan hamster with a white belly yesterday around 6pm. His name is Tito, and he's about the size of a golf ball when curled up, with a distinct blue dot on his right ear. We last saw him in the living room near the window, but he might’ve squeezed out when I opened his cage to refill his water. I’ve been searching around Riverside Park by the Great Falls Public Library on 3rd Ave North, and I’m really worried; this little guy has sentimental value, he’s been part of the family for years. If anyone spots him, please email me at [email protected]; I’ll gladly offer a small reward for his safe return.
