I have a female "torti" cat. She has some of the characteristics attributed to torties. When I try to get her to get off my chair so I can do work on my computer she hisses and bats at me, for example. Even so she is quite a sweet cat. Does the condition that causes the tortoise shell coloration and the high frequency of the female sex also influence the personality? Do torties have a characteristic personality named "tortitude" or is this just myth?
