Ferret with blue harness and heart-shaped chest patch

I lost my ferret, Clover, yesterday around 6pm. He's about 2 pounds, white fur with a black mask and a heart-shaped white patch on his chest. He wears a light blue harness with a tiny silver bell, which clinked when he slipped out of his leash. I last saw him darting toward Bronson Park on West Michigan Avenue in downtown Kalamazoo, near the Kalamazoo Public Library. I'm devastated—Clover is my first pet and this little guy means the world to me; if anyone spots him around Southwest Michigan, please text me and I’ll come get him.
