General: feral on feral
Used when ferals are depicted sexually with other ferals.
Note that for tagging purposes, human-like intelligence (sapience) does not determine whether or not a character is feral, it is entirely related to their physical form. In other words, if a human transformed into a wolf and starts having sex with a feral wolf, it is considered feral_on_feral, but not bestiality.
- Frequently used with interspecies.
