@MLClark I knew someone online who bred Scottish Folds, they are beautiful cats but you have to be careful breeding them. If I remember correctly you’re supposed to breed a folded ear with a straight ear or you get osteochoendrodysplasia. Unfortunately, because the folded ear cats go for more money disreputable breeders will breed folded with folded, ensuring folded eared kittens, so they can get more money.
I’m thankful your friend was willing to adopt one of those kitties.
