A Sumxu Cat
Alternative Names

Droop-eared cat



Cat (Felis catus)
List of Cat Breeds

Experts aren’t sure if this animal was a mythical creation or a once-living cat; the Sumxu is now considered an extinct breed, but suspicions still remain. It was first described in 1656 in South China. Since then, anecdotal accounts, informal descriptions, and artistic interpretations have clouded our understanding of its history.

The droop-eared cat earned its name due to its supposedly droopy ears. One author in 1655 described the cat as having “pendulous” ears much longer than that of other cat breeds. It also was said to have yellow or black fur and resemble a marten. Some cat enthusiasts suggest that the Sumxu was proof of a cat and marten hybrid, however, this has no scientific basics.
