I've seen this countless times that only Maine Coons have an 'M' on their forehead. A few people I know have been told that by their vets too. But don't the majority of tabbies have 'M's on their foreheads? Casie had the 'M' and she didn't look anything like a Maine Coon and when I look up pictures of other breeds the tabbies almost always have the 'M'. So is it really true when people say only Maine Coons have the 'M' on their forehead?
