“feral” is just a widely-accepted terminology within the furry community to describe non-anthropomorphic characters, regardless of their intelligence.
Do we just use the tag “lifelike feral” for all the ones that are actual animals even if it doesn’t look realistic? Like, cartoony? Sorry, I’m not doing a good job explaining.
non-sapient, if that helps.
lifelike feralrequires realisticness AFAIK.
