Gray tabby cat with white paws, pink collar

I lost my gray tabby cat yesterday around 3pm. He's a medium-sized guy with soft striped gray fur, white paws, and a pink collar with a tiny silver bell. He has a crescent-shaped scar above his left ear and a small white dot on his chin. I last saw him near the Big Four Bridge entrance by Waterfront Park along the Louisville Riverwalk; he slipped away while I was crossing near Bardstown Road. He’s been a constant support during rough weeks, and I’m really worried—this cat means a lot to me. If you’ve seen him, email me at [email protected] and I can come get him right away. Any help would mean the world.
