Scottish fold

Scottish fold

a breed of cats all of which trace their parentage to a mutant Scottish farm cat. Their distinctive feature is the forward and downward folding of ear cartilages that becomes apparent as kittens mature. This is inherited as a dominant trait which when homozygous is associated with multiple cartilaginous and bony malformations. To avoid these defects, Scottish fold cats are bred to normal eared cats and about half the offspring are otherwise normal cats with the fold.
