Missing Black Cat (Aurora)

Missing black cat as of 9/29. He got out early in the morning, he is an indoor cat and has never been outside for long. We are worried sick. His name is Keanu, he has green eyes, should hopefully have a red collar still on. He also has a white patch on his belly. His collar is a breakaway collar so we are hoping it’s still on. Please let us know if you see anything.
