I've noticed that of other short-hair, lots of white calicos. I had one with long hair and LOTS of black, Miss Pitty-Pat, named after Aunt Pitty-Pat in GWTW, she was that addlepated! You could do anything with her and she was just the sweetest, fluffy thing with a teeny-tiny meep of a meow and a very loud purr. I would put her on her back, on my knees out to the end of them, supporting her head with my hand and rub her belly; she would pump the air, making biscuits, and sing so loudly!
