I am pleased to report that the formerly lost Otis, has been found! As only a cat can do, Otis decided to go into a part of the carriage house that no one ever enters. Other than being a little skinny, Otis is perfectly okay and is very happy to be back with his parents.
Thank you everyone in the BHB community for keeping a keen eye. Now if we can just find some cooler weather, things would be great!
