Do you suppose different fursona species have better and worse relation with one another, like astrology signs? That'd be funny and awesome at the same time

I've never heard it put that way before, but it's an interesting observation. A lot of animals are culturally associated with personality traits (e.g. clever foxes, loyal dogs, proud lions) and furries usually choose a species they relate to, so it creates a system where people tend to self-sort into various tribes based on values and personality type. Look at any decently popular species and you'll likely find that most of the people repping it share a common set of traits.
