Cat still missing from Vollentine-Evergreen area. Been missing since Dec 21st. Answers to Charlie

My wife posted him at the beginning of the week and we are still looking for him. If anyone has seen him we are getting very worried. Any possible spottings around the area would be appreciated. We’re chasing down any leads. 13 Y/O orange tabby with white stomach and feet. Is in remission from diabetes and is only supposed to be eating wet food. Very friendly.
