Everything that I know about Therianthropy.

Therianthropy is a term originally from Greek meaning “wild animal” and “human.” Historically, it referred to mythological shapeshifting (like werewolves), but in modern usage it also refers to a personal identity experience where a person feels, mentally or spiritually, that they identify as a non-human animal.

Therianthropy is not a medically recognized mental disorder as of the time of writing this.

Psychological therianthropy
The identification with an animal may come from neurodivergency, the subconscious, or personal coping mechanisms developed over time.

Some theorize that early experiences (like trauma or unique brain wiring) could contribute to how someone relates to an animal identity.

There are rare clinical conditions (like clinical lycanthropy) where someone literally believes they are an animal, but that’s distinct from how therians describe their experience.

spiritual identity
The connection to an animal might be understood as a spiritual essence that resonates with that animal.

This interpretation is personal and varies. It isn’t tied to a specific religion, and many therians who think spiritually about their identity still practice entirely separate religions or none at all.
