Cat missing from Harwood/Charles Village

Tux went out an open window last night from my house in Harwood/Charles Village area. He's 4 and probably hiding (hopefully nearby). I put up flyers and let my vet know, but I don't know if there are any shelters or other vets I should reach out to - but I bet he's hiding in someone's yard I just don't know how far he would have wandered overnight. Please keep an eye out for him!
