I don't see the Zip Drive cable, or the serial to parallel printer converter cable, or the late '90s, early 2000's phone chargers, or the rabbit ear adapter for cable input, or any of the various rca sound/video plug converters 3 -> 2, 2->1, 1->2 etc. If they are breeding I would be worried about the gene pool. They're liable to end up like cheetahs, who are all closely related to each other. Or for that matter, my father's side of the family - we found a genealogy going back to 1500 in Italy and due the small Jewish community, there are 3 family names generation after generation. I'm surprised (and a little disappointed) I don't have 6 fingers.
