Furry Lifestyler
The common word 'Furry', used as a noun, denotes a furry fan, a person who has an interest or appreciation for furry subjects in art, culture, and literature.

A furry lifestyler, by comparison, is someone who has a deeper connection to the animal of their choosing. Not necessarily to a shamanistic or therianthropic degree, but to a degree where they see their animal containing some qualities as a reflection of themselves in some fashion.
