Every 7 kittens born, 6 are normal size and 1 special size!

Tad, just because it's not breedable doesn't mean there's no pattern programmed into the cats.
The two aren't mutually exclusive.

But apart from that, yes, it's pretty much nonsense to think there's some conspiracy or hidden agenda on the part of KC that makes certain sizes appear at certain exact intervals.
