Lost tabby cat with blue collar near Lincoln Road

I lost my gray tabby cat, Pixel, yesterday around 3pm. Pixel is medium-sized, short-haired, white chest and paws, green eyes, and a blue reflective collar with a tiny silver bell. There’s a small notch in his left ear and a faint scar on his right hind leg. Last seen near Lincoln Road Mall in South Beach, around the Walgreens at 1100 Lincoln Road and along the boardwalk; I’m really worried—he’s my indoor cat and I miss him a lot.
