Animagus Wilderness

I jot down some traits, focusing on things like: is the applicant introverted / extroverted, wants to live in air / on land / in sea, etc. From there, I narrow it down a bit. Most mammals are more extroverted, but not all. Playful leans toward the small to medium mammals (primates, small pack animals). Shyness leans toward herd animals. Etc. I think about the evolution of the traits; I don't know if I can explain my thought process though.

I'm actually thinking of making a big matrix of animals for animagus voting, but I doubt I'll ever get to it.
