I am with zoology girl. I used to obsess but am a little less prone to it now (with snakes, at least) that I know about what to expect. It's a wonder I didn't worry my first cornsnake, Hokie, to death!
I am still like that with other new pets, to an extent. Our almost 6 month old puppy is currently getting most of my "obsessive" attention. I can hear him instantly in the middle of the night if he so much as stirs... and wake from a dead sleep if he starts to go potty where he's not supposed to. I've heard new mothers of humans are the same way. :bang:
