CFA breeders have stated that using only Fold to non-Fold breeding has eliminated problems with stiff tails, shortened tails and bone lesions. In the FIFe discussion, the representative for British breeders claimed that they were not seeing the problem in their cats and that the study which showed that all heterozygous also have the condition had a small sample size. An offer of free X-rays was presented to 300 breeders to find a Fold cat with healthy hind legs but it was never taken up. A similar offer was set up by the World Cat Federation together with researcher Leslie Lyons but there was also no response. FiFe stated that they will not consider recognizing Scottish Folds if breeders will not allow their breed to be scrutinized.
