I had a pixie point that I put with a Scotty Fold and it passed 8 Soft Curl before I got a Pixie, after 14 boxes and only 2 Pixie Points I gave up. Some Traits just don't pass and I will dispute with anyone that says you have a higher chance at getting the shown to pass when I have had numerous cats pass nothing but hid, Just retired a shadow who passed Toffee Caramel 5 weeks in a row and out of 11 breeds passed Shadow a total of 3 times. Got a Galaxy Gator currently passing Odyssey Bellini more often.
Of course my starters who I want to pass the hids, not a hope in hell!
I also agree that swapping mates makes no difference at to what a cat passes each time, its traits are set and the coin toss on that cat is unaffected by its mate which is undergoing the same coin toss. I also don't believe that waking them or drugging them makes any difference at all, or not doing that. Its pure luck every single time they breed unless its pure. And so damned frustrating its a wonder we don't all quit, I think we are all just masochists at heart
