Jen, now that I have 9 kittens ( which were mostly given to me in June) and 11 adults to care for, I realize now that I have too many cats. However I do not have a spraying problem with any of them. I could be due to my selection method for choosing which cat I want to care for. I remember last year while in central Calif. I had 2 cats who were constantly spraying. Neither were very affectionate, and otherwise, independent, and neither got along well with other cats. One of them was a female, and she did not get along well with her own kittens, after they had grown up. I usually kept them outdoors. All of my menagerie now, indoor cats. I even opened up the basement of this house in order to double the living space for all of them, appx 6200 sq. ft.
