On the Ryukyu island chain (an arc from Kyushu to Taiwan including Okinawa), if you kill a cat with a car, the car will be haunted by the cat’s dead spirit. To counter this, bury the cat at the edge of the town with cooked rice, bean paste and salt. On the same islands, cats are sometimes eaten for medicinal purposes.
In Akita, if a cat or dog dies you should spit on it three times and walk around the corpse three times to dispel the bad luck; if you do not do this, the spirit of the animal will haunt you. Alternatively, you can leave the corpse in a bamboo forest.
If you leave a cat with a dead body, the body will dance.
