She's certainly a pretty girl. As for the size, that might have been typical for the breed originally, but you know what happens when show people get ahold of a bred. Maine Coons are known for their size, so the show cats are bred to be big. I've seen a purebred male at shows around here that is HUGE! I would guess over 30 pounds and all muscle. He's an orange tabby, by the way. They breed for all colors, though brown tabby is typicly what we think of, and probably what many of the natural Maine Coons were. My guy is solid black. By the way, in cat show terms the tortise/tabby pattern is refered to as "torbie", and like calaico and tortiseshell it will almost always be female.
