'furriness' - the feelings, emotions, thoughts and lifestyle that result from your attitude towards animals / relationship with your 'phenotype'.
Wolf, and dolphins during my childhood. Occasionally the dolphin returns when I'm around water.
I'd like to be an anthropomorphic wolf, ideally able to shift to a four legged form, but retaining my sentience.
A very great deal - which is why I try to avoid thinking along those lines too much.
I dream of being able to walk through the streets, muzzle and tail held high - in short to live the life I have now in my true form. I also dream of being able to walk away from that existence, into the wilderness, knowing that I am equally well adapted for that existence too.
In general I find it easier to begin to shift into my fur side when I am relaxed. This tends to mean in the company of other furs, in the outdoors, away from work. Curiously the wolf-thought can take over when I am most stressed, mentally and physically, and over-tired.
