Scottish Fold kittens are born with straight ears. At about three to four weeks of age, their ears fold…or they don’t! It is usually around eleven to twelve weeks of age that the breeder can determine the quality (pet, breeder or show). Presently, only folded ear cats of Scottish lineage are permitted in the show ring, and naturally, every breeder wants to produce show cats. The straight ear progeny of Scottish Folds, nevertheless, are invaluable to the breeding program.
