I got Pixie at 8 weeks but I was home 24/7 and I really am glad I was bc you do have to make sure that they are eating at least 4 times a day and can I plz suggest an ex-pen they sell them at pet smart
http://www.petsmart.com/product/index.jsp?productId=2753756 I set mine up the elongated way and had a plastic runner from home depot underneath for accidents. Then at one end I had her bed and in the middle her food and water and then near the end where the gate opend I had a pee pad tray. I really think a ex pen is the answer if you cannot be home as much bc at least they can move around and are not confined to a crate. good luck with your little one
