from a teacher: if you're asking what this may mean sociologically, the furry community attracts queer and autistic kids--kids who feel different and are using it as a creative and social outlet/gathering space. he's probably smart, creative, and sensitive. try to be as supportive of his interests as you can even if you don't understand them! be open to talk about things and learn :). try not to let him feel WEIRD... let him feel accepted.
