We used a pen made for dogs for Bentley when we first got him and kept him on our kitchen tile when we were gone. He kept getting out but we couldn't imagine with him being so little that he was jumping. The little rascal was actually using all four paws and putting them into the holes and climbing up to the top and then jumping out. We put up a video camera to see how it did it. Needless to say, we no longer call him Bentley... he is our loving Monkey!
