Rachel I have a big blue crate I got at Wal-Mart and pee pads that I put inside it....
here look at this picture. I fold them in half and place it in the back. She uses the pee pads most of the time...but lately she is out of her crate, unless I'm going out. Also I heard to neuter your boy before he starts hiking up his leg and he wont mark your house later...or spry the furniture.
Best of luck with your little one. If I can help holler at me!! or someone here will help.
