There are no stray dogs in urban areas of Japan, but we can see stray cats sometimes.¬†Most cats run away when someone approaches, but some cats are familiar to humans.
There is also “regional cat”. They have no specific owner, but volunteers in the area feeds and watch over them.¬†They do not breed because they have undergone castration surgery. There is a notch in the ears of the castrated cat.
I do not know whether the anime of the “Youkai Watch” is being televised in the Philippines,¬†Jiba-nyan also has incise¬†in his ear, so he can not make offsprings. He dead already. He is a ghost called “Youkai”.
