Species: bakeneko
The bakeneko (化け猫, "changed cat") is a type of Japanese yokai, or supernatural entity; more specifically, it is a kaibyō, or supernatural cat. It is often confused with the nekomata, another cat-like yokai. The distinction between them is often ambiguous, but the largest difference is that the nekomata has two tails, while the bakeneko has only one.
