Is there a test for them now? Can you give me a link or something? Over here we breed folds always with a Brit, so this doesn't become an issue. I hope it would be done much more elsewhere too (unless the test is reliable).
Personally I would avoid breeding with a double fold, the kittens wouldn't get triple fold ears and that's how they really are supposed to be (in shows at least) and I think most of the 'unfolding' folds come from a breeding with a single or double fold cat. Unfortunately we have lots of BYBs here breeding folds, and their cats & kittens often have very weird semi-straight ears.
l'm not sure about the involvement of the testing. l went to the breeder looking to buy a British Shorthair, and she gave me all her history and good breeding paractices about both the Shorthairs and the Folds - she breeds both. l was paying more attention to the British Shorthair content, but l do remember for sure that she said something to the effect that because she is a responsible breeder, if she does mate Fold to Straight, that the Straight is always tested first.
