Gray tabby with white paws, missing near Friendly Center

I lost my gray tabby cat named Niko yesterday around 3pm. He's small-to-medium, short-haired, with a gray tabby pattern, white chest, and white socks on his paws, and he wears a blue collar with a tiny silver bell. He has a bright green eye and a notch in his left ear. I last saw him near the Starbucks at the Friendly Center on Battleground Ave in Greensboro; he’s a rescue and means the world to my daughter, so I’m really worried and grateful for any sighting or safe return.
