This reminds me of The Golden Compass. If I could have a spirit animal it would be the ocelot. I did a project on them in like 5th grade and loved them ever since.
It would be super fitting tho too. They are small but fierce when they need to be. I think I'm a nice person, a little too nice sometimes but when I get mad its not pleasant. If I chose a tiger or lion that would be lame cuz I know personality wise that doesn't fit. I'm not that tough. They are also nocturnal. That's the major similarity between us. And last, they are loners. Sometimes they let others into their circle but they spend most of their time alone. I'm a loner sometimes too. Partly cuz everyone lives far away but partly cuz I'm weird and sometimes I just wanna sit in my room all day and not talk to anyone.
