Over the last year, I've bought about 50 starter cats (of various collections etc.) and got a grand total of 3 special sizes out of them, 2 being bigger de bigs and one a mega (that's 3 special sizes out of the entire breeds coming out of 25 pairs, so 3 in about 400 kittens were special sizes).
Which is about the same ratio I get overall for special sizes.
