When my vet was explaining about the orange gene being predominantly male, I think she said something about their dispositions too. You wouldn't think (I didn't) that a "mutt" type of kittie would have a certain disposition. At any rate, they are known to be sweethearts :) Sorry to hear about the cancer... how old was she?
I'm not sure exactly how old she was - the vet thought she was somewhere around 8 or 9 when she passed on.
