Karloff is dumb (and needs help with breeding)

[Vrem Vaniva]

I'd want to look through unopened boxes, to see if there are some that you previously thought to be "dudders," but verifiably are hiding *only and exactly* foxie ears. When those do throw their foxie ears, especially if you have 2 of them together throwing foxie as their recessive, then you've got a solid unmixed ear. If those come from your foxie blondies with blonde whiskers, great.

Beyond that -- i second what Inia says about practical advice for carrying forward. It is correct, what you ask, "But because the new boxes are both showing OBB ears, and you can't have a dominant hiding behind a recessive, the cats are also both hiding OBB, is that correct?". You can never get Foxie ears from the Ody Boo Boo eared cats paired together, never. (You could get Foxie showing, only with foxie eared mates, or foxie-hiding mates, but the new boxes will be hiding OBB and it will come out again.)

When you "bury the trait" and pull it back out again ... You can do that with Nick and Catherine having separate mates, each with a super-nice mate with more dominant ears ... well, the boxes can be hiding Ody Boo Boo ears instead of Foxie. So it could become a long process.

Why would Nick or Cath be more likely to throw their shown ear when paired with , say, a soft-fold mate? ( No reason: at this point we're into the magic method. ) They will throw either the foxie-ear gene or the odyssey boo boo gene. So the resulting kitten box , showing soft fold, could contain a buried foxie or a buried ody boo boo, and you won't know until you breed it.
