I really don't have a clue, as I don't have a cat. But my friend had a cat that seems to fit your description. She is female, indoor cat, and a tuxedo. She is a beautiful cat, but not too friendly. She doesn't really like visitors. Actually, she's a bit pyscho. Like one time I was brushing her. She was all stretched out, purring, and seemed to be the happiest cat in the world. Then she got this possessed look in her eye, and suddenly just grabbed my hand and bit me! She drew some real blood, I still have a scar.
