Where do kittens like to hide in the house?

The best place is the place you are the most (excluding the kitchen and bathroom and garage). For example let's say you are in the living room most of the day and your kitten is with you, then she is used to the environment and will feel safe in there. But if your leaving your kitten alone in the house, just buy a small play pen for dogs or cats at your local pet store (I recommend petsmart). Just make sure your kitten won't be able to get out of the play pen or won't get hurt in it. Also the play pen has to be a bit roomy so your kitten doesn't feel trapped in.
