Small-eared cats include small-eared cats, Scottish folding cats and exotic short-haired cats. These cats have small and lovely ears and are deeply loved by the public. However, the Scottish folding ear cat, although cute, has genetic defects. If they suffer from genetic diseases, they will be in great pain. At present, there is no specific treatment plan. Therefore, if you want to raise a folding cat, the owner needs to be mentally prepared.
