Kaibyō

Kaibyō (かいびょう, "strange cat") are supernatural cats in Japanese folklore. Examples include bakeneko, a yōkai (or supernatural entity) commonly characterized as having the ability to shapeshift into human form; maneki-neko, usually depicted as a figurine often believed to bring good luck to the owner; and nekomata, referring either to a type of yōkai that lives in mountain areas or domestic cats that have grown old and transformed into yōkai.

The reason that cats are often depicted as yōkai in Japanese mythology can be attributed to many of their characteristics: for example, the irises of their eyes change shape depending on the time of day; their fur can seem to cause sparks when they are petted (due to static electricity); they sometimes lick blood; they can walk without making audible sounds; their sharp claws and teeth; their nocturnal habits; and their speed and agility.
