Cat's are often seen as sly and mysterious creatures..
Cats depicted as yōkai in Japan date back as far as the Kamakura Period (1185–1333).
In the collection of setsuwa (oral tradition of folktales before the 14th century), the Kokon Chomonju from this period, there are several descriptions of cats that do odd and suspicious things, noting that "these are perhaps ones that have turned into demons.

One of the more well know legends regarding a Bakeneko...
is the story of Takasu Genbei...
In this story a man named Takasu Genbei, whose mother's personality suddenly changed after his pet cat went missing for many years. His mother avoided interactions with old friends and even family and would often eat alone in her room. Untill one day when the family peeked in on her, they saw a cat-like monster in the mother's clothes, chewing on animal carcasses. Takasu, still skeptical, slew what looked like his mother, and after one day his mother's body turned back into his pet cat that had been missing. Takasu then tore up the floorboards of his mother's room to find her skeleton hidden there, her bones gnawed clean of all flesh.

Folk lore:.....
The Bakeneko myths from arond Japan....In Yamagata District, Hiroshima Prefecture, it is said that a cat raised for seven years or longer would kill the one that raised it. There are also many regions where when people began raising a cat, they would decide in advance for how many years they would raise it because of this superstition.
Also, depending on the area, there are stories in which cats that were killed by humans in a brutal manner would become bakeneko and curse that human. The stories of bakeneko are not only about aged cats, but are also sometimes stories of revenge against cruel humans.
The abilities attributed to the bakeneko are various, but include shapeshifting into humans, wearing a towel or napkin on the head and dancing, speaking human words, cursing humans manipulating dead people, possessing humans and lurking in the mountains and taking wolves along with them to attack travelers.
As an unusual example, on Aji island, in Oshika District, of the Miyagi Prefecture and in the Oki Islands, Shimane Prefecture, there's a story of a cat that shapeshifted into a human and wanted to engage in sumo.
However the legend of cats with the ability to speak, may have arisen because humans simply misinterpring the cat's meowing as human language, and for this reason some would say that the cat is not a type of yōkai. In 1992 (Heisei 4), in the Yomiuri newspaper, there was an article that argued that when people thought they had heard a cat speak, upon listening a second time, they realized that it was simply the cat's meowing and that it was only coincidence that it resembled a word in human language.
In the Edo period (1603–1867), there was a folk belief that cats with long tails like snakes could bewitch people. Cats with long tails were disliked and there was a custom of cutting their tails. It is speculated that this is the reason that there are so many cats in Japan with short tails nowadays, because natural selection has favored those with short tails.
Folk beliefs that cats can cause strange phenomena are not limited to Japan. For example, in Jinhua, Zhejiang, in China, it is said that a cat, after having been raised for three years by humans, would then start bewitching them. Because it is said that cats with white tails are especially good at this, there arose the custom of refraining from raising white cats. Since it is said that their ability to bewitch humans comes from taking in the spiritual energy of the moon, it is said that when a cat looks up at the moon, whether its tail has been cut or not, it should be killed on the spot

The reason that cats are seen as yōkai in Japanese mythology is attributed to many of the characteristics that they possess: for example, the way the irises of their eyes change shape depending on the time of day, the way their fur seems to cause sparks due to static electricity when they are petted (especially in winter), the way they sometimes lick blood, the way they can walk without making a sound, their wild nature that remains despite the gentleness they can show at times, the way they are difficult to control (unlike dogs), the sharpness of their claws and teeth, their nocturnal habits, and their speed and agility.
There are many yōkai animals other than cats in old tales that have similar attributes: the deep tenacity of snakes, the ability of foxes (kitsune) to shapeshift into women, and the brutality of tanuki in eating humans depicted in the Kachi-kachi Yama folktale from the Edo period. Cats in particular, however, have acquired a great number of tales and superstitions surrounding them, due to the unique position they occupy between nature and civilization.
As cities and towns were established and humans began living farther apart from nature, cats came with them. Since cats live close to humans yet retain their wild essence and air of mystery, stories grew up around them, and gradually the image of the bakeneko was formed.
One folk belief concerning the bakeneko is that they would lick the oil of oriental lamps, and in the Edo period encyclopedia, the Wakan Sansai Zue, it is said that for a cat to lick this oil is an omen of some strange event about to occur.
People in the early modern period used cheap oils from fish, like sardine oil, in the lamps, and that could explain why cats would want to lick them.
The diet of most Japanese people at that time was based primarily on grains and vegetables, and the leftovers would be fed to the cats.
However, since cats are carnivores, such a diet would have been lacking in protein and fat, and therefore they would have been even more attracted to the oil in the lamps.
Furthermore, the sight of a cat standing up its hind legs to reach the lamp, with its face lit up and eyes round with anticipation, could have seemed eerie and unnatural, like a yōkai.
The mysterious air that cats possess was associated with the image of prostitutes who worked in the Edo period red-light districts. This was the origin of a popular character in kusazōshi (among other publications), the bakeneko yūjo
