I'm not quite sure why you are so hung up on the cat breeding thing.
I never said anything about breeding programs being the reason we have the cats we do now. Certain dominant traits rising to the surface through isolated populations is what I was referring to, not some program of people actively breeding cats. The latter is not the cause of all the species we have now, but people in recent years have certainly crossbred cats to see what is possible: enter ligers and tigons... Refer to the page I posted in #92. It seems that the limiting factor in cross-species cat reproduction is not genetics, but the size of the cats.
