Senri, also known as Xian Li, are said to be old leopard cats that have gained divine powers in Chinese mythology. They can take the form of attractive men or women and drain the spirits of humans. The Japanese Nekomata is thought to come from tales of Senri.
"Origin: China. A mountain cat youkai and powerful Nekomata. Like Senko, they have lived long lives, strengthening their powers. They, too, take on the form of women and drain men's energy to enhance their own power."

Shin Megami Tensei III: Nocturne
"A Japanese monster born from a lynx. It absorbs spirits from men by transforming into a beautiful woman. It is said that other monsters collect spirits to become a Senri."
"In Japanese folklore, the senri are creatures that come into being when an extremely old mountain cat undergoes a spiritual transformation. It can take the form of a beautiful young lady and seduce unfortunate men that wonder into the mountains. It then steals their life energy in order to sustain itself and gain more power. The senri is the highest rank of bakeneko, and it is said that other animals that have become demonized gather life energy so that they themselves can become Senri. The senri are akin to the Chinese spirit animals known as the yao jing, which achieve human form after many years of training in the art of Taoism. "
