It is better to keep your little one in a room by herself with her food, toys, litter box for the first few days. Of course when you are home play with your kitten, speak softly to her, give her little treats. She will be a little overwhelmed at first and she may just hide, but it won't last long. When I got mine as babies this is what I did and they had no problems with the litterbox after they had free roam of the house. Make sure you kitty proof before she gets home, some kittens love to chew on electric cords. Also, if you have any delicate things on a mantle or shelve you may want to keep those where the kitten can not reach, I learned this the hard way. Enjoy your kitten and can not wait to see pictures of your little one.
