The breed was not accepted for showing in Great Britain and Europe because people thought that they would be overly prone to ear problems such as infection, mites, and deafness, but the Folds were sold in America. The breed kept on growing using crosses with British Shorthairs and American Shorthairs. Despite the initial concerns, the Fold breed has not had the expected mite and infection problems. However, wax can build up faster than in the ears of other cats.
