Too much info, Ran.

This is merely a fan made 4koma, but it is pretty amusing to think about a bakeneko, who is basically a cat that lived so long it became youkai, splitting its tail, stood on its hind legs and could take on human form. You'd think that instinctively, she would know about mating and the requirements for it. This way is cute too.
