The sumxu, Chinese lop-eared cat, drop-eared cat, droop-eared cat, or hanging-ear cat, all names referring to its characteristic feature of pendulous ears
The Sumxu, also known as the Chinese Drop-Eared Cat, is a fascinating, ancient, and highly enigmatic breed reported in historical Chinese texts for centuries, famous for their unique pendulous (hanging) ears. They are widely considered to be an extinct or highly mythical popular cat breed from antiquity.
Because the Sumxu is likely extinct (or was a historical misidentification), keeping them as modern pets is impossible. However, if they existed, choosing ancient, historical cat names would be appropriate. Their pet care would likely involve the specialized ear cleaning required for drop-eared animals, similar to dogs, to prevent severe chronic ear infections.
