I love all these cats,(especially OREO), it brought back such fond memories of a cat I had growing up named Sylvester. He was the first cat that was truly mine, rather than a family cat. He would follow me everywhere I went. Unfortunatly he disapeared one day and I suspect coyotes.
Needless to say, my cats are all indoor-only now.
Here's the only picture I have of him (he was still quite young then!) He's pictured with my very first family pet Smokey. Not the greatest picture, but it's all I have so I treasure it.
Also, as far as tuxedo patterning goes, I had always believed that it is a black cat with white paws (cuffs), chest (shirt) and maybe a white blaze. Like Sasha, my sisters cat
Check her out with all the presents on Christmas Eve!
This isn't my cat, but an image I found through google. This is what I think of when I think tuxedo cat:
