Orange tabby cat missing near CMU campus

I’m desperate to find my orange tabby cat, Milo. I last saw him yesterday around 3pm near the CMU campus, specifically along University Avenue by Warriner Hall, and he bolted into a neighbor’s yard. He’s an adult tabby, about 12 pounds, with a bright orange coat and a white bib, and he wears a blue collar with a tiny silver bell. He also has a small notch in his left ear and a faint scar on his nose—hard to miss if you know him. He’s not just a pet; he’s family, and this has been really tough on me—please reach out if you’ve seen him.
