We carried her out to the car in a shoebox, which upset her deeply. I gave her my finger to gnaw on through one of the holes in the box, but it wasn't much comfort. So once we were in the car I let her out.
While (e:zobar) went into Wegmans to get a litterbox and some kitten chow, I let her roam around the car. She climbed up on my headrest, leapt around the back seat, climbed up into the rear windshield ledge and stalked the guy collecting shopping carts, and then abruptly remembered I was there and came flying back to chew on my nose.
We got her home and let her explore the house. After she ravenously devoured like, five kibbles of kitten chow, she ignored the food and wandered around.
Then I played with her with a cat toy for about half an hour. I finally wedged it between my mattress and box spring so the string part would hang down. It took her fifteen minutes to bust it apart and carry the feathery fur-mouse away to gnaw on it.
Now Z has gone to bed, and I am in my bed, and she is wandering around the house meowing. I called her and she came racing into the bedroom, took a flying leap, and made it up onto the bed, where she briefly gave me lovies, but then leapt off to explore the house again.
Oop, she's back. She's climbing on my head and shoulders and down my back, purring like a small electric motor, the function of which is to produce cute.
There are four more kittens. They are all this cute. See (e:leetee)'s post for more details.

Update: Aw jeez, she keeps running across the room and smacking into the mirror. I think she's looking for the other kittens. :( I don't have room for that many cats in this house!
I kinda have to agree with (e:imk2) about getting her a sibling. That being said Make sure they are both spayed or nutered or what ever it is called so that you don't get more kittens. Some other advice that I have heard is to get a collar and a name tag thing. That way if they should ever get out side (assuming they don't get the collar off {breakaway is safer) then if someone sees them they know they aren't a stray. You may even want a bell so that you can hear when the kitten moves around (it can be a help). Somethings are cute when they are small but not when they are big so remember that when you decide if the cat should be punished for something they do. I'm glad someone took that little guy in, hope the kitten brings lots of joy to the home.
hoorah for kittens with homes!
you should totally get her a brother or sister so that she's not lonely.
She's so adorable:).
You two look so damn cute together! Yay! I'm so happy you took her home. Looking forward to the naming process!
