Something that not all people know about, is the tabby "M". As cats.about.com says:
"Probably the most distinctive feature seen in common on all tabby cats is the "M" on their foreheads. You will also see this M on many of the big jungle cats, such as tigers, cheetahs and ocelots."
Living in my own little cat knowledge world, it didn't occur to me that my friend Yousif would not realize that tabbies' having "M"'s on their foreheads is not an unusual thing. His comment on his Facebook picture of his new kitty housemate Majin Buu, was "Look at his forehead! There is an M!!"
