This is what I use, it's awesome, Vinnie can't jump out, there are multiple ways you can shape it to fit in spaces, AND it easily comes apart at each joint, so if you want to take a panel or two out you can!!! We originally pee pad trained, after about a month in we put the pad in the pen instead of by the door, and i think it was just the right amount of privacy for him, he trained instantly! I don't have to feel bad about leaving for work, he goes in with food, water, toys, bed and a pad just in case, i don't want him holding it, and he just loves it, it's like his room! PLUS the panels can be used to make barricades if you want to keep them off furniture or out of rooms!
