I LOVE animals ! ! My very first obsession was animals. Since I was able to read I used to spend my afternoons reading books about animals, trying to visualize what I was reading. It was such a SWEET time !
Right now I'm taking back this interest I had forgotten for a while. I love watching National Geographic Channel, the calendar I have on the wall is made of pictures of animals (zebras this month ), I own two WONDERFUL parrots, I'm considering taking a cat (80% I will), since I was a kid I have always dreamt of owning a Husky (I will, sooner or later), I LOVE squirrels, the only kind of animals I don't like are insects.
I majored in psychology and that was a BIG help for me, but, if I could start again university, I would pick zoology (maybe I will, sooner or lalter).
I remember a nice episode: I was in a park and there was this dog barking at everyone. Then he came near to me and all of a sudden he changed his behavior, stopped barking and looked at me for a LONG while. It was a great moment.
My gamertag on XBOX LIVE is "Rainbow Gamer", to express my love for nature.
And yes, I feel WAY MORE close to (other) animals rather than to people.
Edit: Oh, sorry, I forgot to answer your question.... Yes, I think it's usual.
