I was dicussing this with a friend lately 'cause we can see this behavior in a mutual friend's tuxedo cat (female) which is kept indoors, she's acting unually aggressive and is over-active. When I'm thinking about the first four or five years with my Katz (also indoors, tuxedo and female), I remember she was also showing this tendency, she sometimes attacked visitors and was very destructive. When she got older, this grew out. I have known another female tuxedo kitty who acted the same way, no one but her mommy was allowed to approach her.
Now my friend and I discussed if this is only a coincidence or a tuxedo-typical behavior, maybe genetic.
What are your experiences with tux kitties, especially female indoor cats?
