Are cats with red fur really nuts?

I do believe that my own kitty, Toes, who is a tortie with alot of red is about as crazy as a cat can be. I have had her since she was a tiny baby, and she is now 7, but she is completely psycho at times compared to my other two kitties. She is so skiddish at times, and then very friendly and loving at other times.

I have a sweet red tabby boy who is very sensitive, especially to noises, but he is very sweet and affectionate. My tortie, on the other hand, is a character! She has serious tortie-tude but never fails to entertain!
