Thank you all for the kind words. I should have known I could count on you guys.
Amanda, an x-pen is a play pen for pets. You can use it to keep them out of trouble, a place for them to sleep, play, etc.
Here is the one I have..

You can also get them in metal and different sizes.
LvLaila, I have the house in the x-pen next to my bed. I wasn't sure if he would use it but he really loves to sleep in it. A lot of yorkies like to have their own place to go. If he didn't I figured I could give it to someone.
