Grey tabby cat with blue collar missing near La Plaza

Hey, I lost my grey tabby cat with a blue collar yesterday around 3pm. I was near La Plaza Mall on Paredes Line Road, by the outdoor food court, when he darted off. He's a medium-sized guy, about 10 pounds, with a white chest and a tiny white toe on his left front paw, plus a small orange speck on his nose. His collar is bright blue with a small enamel tag that says 'Milo' and has my number on the back. I am pretty sure he's microchipped, but I can't recall the number right now. This cat is family to me; he's been with us since last year and I am really worried. If anyone finds him, please text me. I would be forever grateful to have him back.
