Health issues of the Scottish Fold cat
There is one medical problem that has been found to be related to Scottish Fold breeding. If both parents have folded ears, their kittens will be extremely prone to developing a painful degenerative joint disease that fuses the tail, ankles and knees.
This condition also affects Scottish folds with one copy of the fold gene, to a lesser degree, and is the reason the breed is not accepted by the Governing Council of the Cat Fancy and the Fédération Internationale Féline.
