I use a metal x-pen from Petco. It is set up in my den. I have a pad, food and water dishes and his bed in it. I also bought a piece of linoleum at Lowe's to put under the pen. This all works great. Copper is about 4 lbs. He does not jump over the pen or climb out. The height of the pen is 2 feet. I like the metal x-pen because I can fold it up to travel and I can also change the shape of it in various ways to suit my needs.
Good luck with your new furbaby!
