Hello and welcome to the forum! It's nice to meet you!
You definitely don't need anything other than feeling like you're a furry to be one. You can just make a quick fursona, or you can run faceless for a year and everyone will be the same either way.
I mean, from my experience, I made a sona basically while writing my introduction. I just went for things I feel are right.
And I didn't change anything since then. It just works.
On the other hand, we do have a certain member here that used a tank as a fursona for over a year. It was hilarious but it worked.
You mentioned hunting, is it culture for you or just a hobby? I like meeting people from different cultures, it's always fascinating.
I hope you enjoy your time here! If you have any questions feel free to ask!
