Right now there is no tag to describe that a feral is a terrestrial animal. That means the bestiality and all other feral tags are applied to fantasy ferals as well as real ones, despite those being very different fetishes. There should be some sort of tag that I could use to blacklist bestiality when it specifically refers to interactions between humanoids and realistic earth animals, but right now there isn't one, and there isn't even a good combination of tags to blacklist that sort of thing. Bestiality is used in real life to refer to that exact thing, so I propose it be used for that, instead of just "feral on (anthro or human)" no matter what kind of feral it is.
